Vitamin D and Immune Health
What is vitamin D? Vitamin D is a fat-soluble vitamin that plays a key role in many bodily processes, especially those related to bone strength and immune function. Unlike most vitamins, your body can actually make its own vitamin D — but only when your skin is exposed to direct sunlight. Specifically, ultraviolet B (UVB) rays trigger a reaction in the skin that produces a precursor to vitamin D, which is then converted by the liver and kidneys into its active form. Beyond sunlight, vitamin D is found in a limited number of foods. Fatty fish like salmon, sardines, and mackerel are among the richest natural sources. Smaller amounts occur in egg yolks and beef liver, and many everyday products — such as milk, orange juice, and breakfast cereals — are fortified with added vitamin D. Because few foods naturally contain much vitamin D, and because modern lifestyles often limit sun exposure (due to indoor living, sunscreen use, and geographic location), vitamin D deficiency is surprisingly common, even in generally healthy individuals. For this reason, many people turn to supplements to maintain healthy levels year-round. There are two main forms of supplemental vitamin D: D2 (ergocalciferol) and D3 (cholecalciferol). Vitamin D2 is typically derived from plant sources like mushrooms exposed to UV light, while D3 usually comes from animal-based sources such as lanolin (from sheep’s wool) or fish oil. There is one vegan source of vitamin D3: lichen, which is an organism comprised of algae or cyanobacteria combined with fungi. Both D2 and D3 can raise vitamin D levels in the blood, but D3 is generally more effective and better absorbed by the body. Absorption also depends on dietary fat, since vitamin D is fat-soluble — meaning it’s best taken with a meal that includes some healthy fat to help your body use it efficiently. However, vitamin D can be made to be water soluble, which greatly increases its bioavailability. How does vitamin D affect the immune system? Vitamin D plays a central role in helping the immune system function efficiently and stay balanced. Rather than simply “boosting” immune activity, it acts more like a modulator — supporting the body’s ability to defend against harmful invaders while also preventing the immune system from becoming overactive. This balancing act is crucial for staying healthy, as both underactive and overactive immune responses can lead to problems. Immune cells throughout the body — including in the skin, lungs, and gut — have receptors for vitamin D, meaning they can respond directly to its presence. In the innate immune system — the body’s first line of defense — vitamin D enhances the ability to recognize and respond to threats quickly. It helps activate important immune cells which are responsible for detecting pathogens and signaling other immune responses. Vitamin D also promotes the production of antimicrobial molecules which act like natural antibiotics and can directly destroy bacteria, viruses, and fungi. These rapid-response mechanisms are essential for containing infections early, before they spread. In the adaptive immune system — which provides more targeted, long-term protection — vitamin D helps fine-tune how immune cells behave. It influences T cells which help keep the immune system in check and prevent excessive inflammation. It also affects B cells, which are responsible for producing antibodies, by reducing unnecessary activation and promoting immune tolerance. In this way, vitamin D supports a balanced immune response — strong enough to protect, but not so aggressive that it turns against the body’s own tissues. Is there evidence that vitamin D promotes effective immune function? Yes, a growing body of research supports the role of vitamin D in promoting effective immune function in a wide range of immune-related outcomes, including: Infections: Some studies have shown an association between low levels of vitamin D and increased susceptibility to colds, flu, and viral illnesses as well as reduced infections with vitamin D supplementation. For example, a randomized controlled trial of vitamin D supplementation by frontline healthcare workers in Mexico found that participants receiving 4000IU/day of vitamin D had a lower rate of infection with SARS-CoV2 compared to those receiving a placebo. Similarly, another randomized controlled trial found that vitamin D supplementation by children aged 2 to 5 years with 2000IU/day reduced infection with influenza (but not enterovirus). Autoimmune diseases: Because of its role in regulating immune function, vitamin D has garnered attention for its potential role in influencing autoimmune diseases. The VITAL study, a large-scale randomized trial, found that participants taking 2,000 IU of vitamin D daily (combined with omega-3 fatty acids) for five years experienced a 22% reduction in the incidence of autoimmune diseases, including rheumatoid arthritis and psoriasis, compared to those receiving a placebo. Similarly, a comprehensive review highlighted that numerous studies have found correlations between low vitamin D levels and both the onset and progression of MS. Additionally, a scoping review focusing on MRI findings in MS patients reported that higher vitamin D levels were associated with fewer new active lesions and reduced lesion volume, suggesting a potential protective effect. Cancer: Emerging research suggests that vitamin D may play a significant role in cancer prevention and management. A comprehensive umbrella review of 71 systematic reviews found that vitamin D₃ supplementation was associated with a 10% reduction in total cancer mortality (odds ratio , 0.9; 95% CI, 0.87-0.92; P < 0.01). Additionally, an analysis indicated that achieving higher serum 25-hydroxyvitamin D concentrations could potentially reduce cancer incidence rates by approximately 70%. These findings underscore the potential of vitamin D in reducing both the occurrence and mortality of various cancers. Inflammatory responses: Vitamin D also appears to help regulate inflammation in the body, acting almost like a natural “dimmer switch” for the immune system. Several studies have found that vitamin D can reduce the production of pro-inflammatory molecules — the kinds that are often elevated in chronic diseases — while increasing anti-inflammatory compounds. This balancing effect may help explain why low vitamin D levels are often linked with higher levels of systemic inflammation. For example, a study found that people with lower vitamin D levels had significantly higher levels of C-reactive protein (CRP), a common marker of inflammation in the blood. While more research is needed, these findings suggest vitamin D may support overall immune balance, not just in response to illness but also in maintaining a healthy baseline state. How much vitamin D is needed for optimal immune function? While it’s clear that vitamin D plays an important role in immune regulation, there is no universally agreed-upon amount that guarantees optimal immune function. Research continues to evolve, and current recommendations vary widely depending on the source. Most guidelines were designed with bone health in mind and may not reflect what’s truly needed for immune support or chronic disease prevention. Blood Levels (25-hydroxyvitamin D) Vitamin D status is measured by a blood test that checks for 25-hydroxyvitamin D , the circulating form of the vitamin. Deficiency is typically defined as anything below 20 ng/mL (50 nmol/L), but for immune function, many researchers argue that this threshold is far too low. Levels of at least 30 ng/mL (75 nmol/L)are often cited as a baseline, but some of the strongest evidence — including large trials like the VITAL study — suggests that 40–60 ng/mL (100–150 nmol/L) may offer the most benefit for immune system balance and resilience. Raising blood levels into this optimal range can be surprisingly difficult with low doses. Many people — especially those with darker skin, higher body weight, or limited sun exposure — require higher intakes for levels of blood vitamin D to increase. Daily Intake (From Diet and Supplements) Although official government recommendations suggest 600–800 IU per day for adults, this level is primarily intended to prevent bone disease, not to support optimal immune function. A growing number of clinicians and researchers now advocate for daily intakes of 2,000–5,000 IU to achieve and maintain optimal blood levels for immune health — especially in people who live in northern latitudes, use sunscreen regularly, or spend most of their time indoors. In fact, research has shown that intakes up to 10,000 IU per day are safe for most people, with no evidence of toxicity at these levels in healthy individuals over extended periods. The commonly cited upper limit of 4,000 IU/day was set conservatively and has been challenged by multiple studies that demonstrate a much higher threshold for risk. Ultimately, because vitamin D needs vary based on genetics, lifestyle, and current levels, the most reliable approach is to test blood levels periodically and tailor supplementation accordingly. Why should vitamin D be taken with vitamin K? Many health professionals recommend pairing vitamin D3 with vitamin K2(typically in the MK-7 form) to ensure that calcium metabolism stays properly balanced — especially when supplementing with higher doses of vitamin D. Vitamin D and vitamin K work together to support not just immune health, but also calcium balance and cardiovascular safety. One of vitamin D’s primary roles is to help the body absorb calcium from the diet. But once calcium is in the bloodstream, vitamin K helps direct it to the right places — such as bones and teeth — and away from soft tissues like arteries, where excess calcium could contribute to plaque buildup. What makes Fringe Vitamin D & K Mix the best in the market? Fringe Vitamin D & K Mix, providing 2,500 IU of vitamin D3 per day, aligns well with the evidence-based perspective of doses that support optimal immune function. It also has three unique characteristics that make it a better choice than other Vitamin DK supplements on the market: Water Solubility – Both vitamin D and K are fat-soluble vitamins, which makes their absorption of fat-soluble vitamins complex and results in a lower bioavailability than water-soluble vitamins (bioavailability refers to how much of the ingested nutrient is delivered to body tissues). The bioavailability of fat-soluble vitamins can be increased significantly through a safe and simple conversion process that makes them water-soluble and able to readily be absorbed through the walls of the small intestine. Research has demonstrated that water-soluble vitamin D is about twice as bioavailable as fat-soluble vitamin D. Vegan D3 – Research has clearly demonstrated that vitamin D3 is superior to vitamin D2 at raising blood levels of 25-hydroxyvitamin D. The vast majority of vitamin D3 supplements source the vitamin from sheep’s wool, which produces a waxy substance called lanolin. Because it is animal based, lanolin-derived vitamin D3 is not suitable for vegans. In contrast, Fringe Vitamin D & K Mix uses the only vegan source of vitamin D3, which is lichen. Lichens are living organisms that consist of fungus combined with algae or cyanobacteria. Lichen-derived vitamin D3 is identical to that produced from sheep’s wool, but is non-animal based, making it suitable for everyone. Vitamin MK-7 - Fringe Essentials Vitamin D & K contains vitamin MK-7, the most bioavailable form of vitamin K. It is derived from the fermentation of Nattō, which is plant-based and suitable for vegan diets. Other ingredients The other ingredients in Fringe Vitamin D & K Mix are all natural and non-GMO. They include inulin and myo-inositol (also sometimes called vitamin B8) to help with dosing, medium chain triglyceride (MCT) oil to help with emulsification, and licorice extract for increased bioavailability. All our products are verified by independent third-party lab testing to ensure that they are free from molds, pesticides, mycotoxins, and heavy metals. We also leave out all the stuff you don’t want like artificial sweeteners, additives, gums, and ‘natural flavors’. Conclusion Vitamin D plays a vital role in helping the immune system function effectively and stay in balance. While there’s still some debate about the exact levels needed for optimal immune function, a growing body of evidence suggests that many people benefit from higher blood levels and daily intakes than current guidelines recommend. Maintaining healthy vitamin D levels is one of the simplest and most impactful steps you can take to support long-term immune resilience, and Fringe Vitamin D & K Mix is an ideal supplement to help you achieve this goal.

Sodium: Yeah or Nay?
Sodium: Yeah or Nay? Fringe Electrolyte & Mineral Mix contains 190mg of sodium. Of all our supplement ingredients, sodium is the one we get customer queries about most often. These questions generally fall into two camps. In the first, people ask us “is it safe for me to consume that much sodium in an electrolyte supplement 1-2 times per day?” And in the second, people ask us “why isn’t your sodium content higher, like it is in some of the other electrolyte supplements on the market?” Our answer is pretty simple. We formulated the sodium content of our electrolytes with Goldilocks in mind: not too much, and not too little – but just right. Our level of sodium is safe for (almost) all kids and adults when taken as recommended. However, it’s absolutely true that as far as minerals go, sodium is the one whose optimal level of intake is most hotly contested in scientific circles. In this article, we’re going to give you a bit of insight into the sodium controversy, and how we came to determine the level that is “just right” for our customers. Shop Fringe Electrolyte & Mineral Mix Camp #1: "Whoa! Shouldn't I LIMIT my intake of sodium?" Here are some of the points that support this argument: + Supportive points: Several chronic diseases, including hypertension, cardiovascular disease, kidney disease, and osteoporosis have been associated with high sodium intake. And while association does not necessarily equal causation, there is also some causal evidence that shows that high intakes of sodium can be harmful to health for some people. People who experience poor health in response to sodium are called “salt sensitive”. These people experience an increase in blood pressure with higher sodium intake. Several medical organizations (such as the World Health Organization) recommended a low intake of sodium, in the range of 1500-2300mg/day. Camp #2 "Whoa! Shouldn't I be consuming MORE sodium?" Here are some of the points that support this argument: + Supportive points: The majority of people are not “salt sensitive”. Contrary to popular belief, some research suggests that consuming low sodium (less than 2500mg per day) may be associated with higher, rather than lower, blood pressure. In contrast to the recommendations that US adults should consume 1500-2300mg/day of sodium, research has shown intakes of sodium in this low range can be harmful to health, including increasing the risk of cardiac death, insulin resistance, and adversely affecting blood lipids. The average global intake of sodium per day is 3000-5000mg per day and has been remarkably stable across cultures for many decades, which suggests that this range of intake can be considered as “normal” (even though it is much higher than the medical recommendations). In studies showing harm, sodium intake may be a “red herring” for other more important dietary habits, such as consuming too much. Camp #3: Fringe Electrolyte & Mineral sodium content is JUST RIGHT! Here’s why our sodium content is “just right”: + Supportive points: The PURE study found that sodium intake between 3,000–5,000 mg/day was associated with the lowest cardiovascular risk. Some people, like folks consuming a whole food, paleo or keto diet, usually consume below 2500mg sodium/day, so they can use some additional sodium in their diet. Additional sodium is also needed in many other conditions, like sweating, illness, and hot weather. However, supplements that contain 500-1000mg sodium per serving can quickly bump up daily sodium intake. Think of it like climbing three stairs at a time, rather than one. At just under 200mg sodium per serving, Fringe Electrolyte & Mineral Mix gives you more control over how much sodium you want to consume. Instead of lunging up those stairs, you can do a steady climb, simply by increasing the number of servings per day! All other ingredients in Fringe Electrolyte & Mineral Mix (including chloride, magnesium, calcium, potassium, and trace minerals) are also safe to consume in higher amounts. And if you’ve never seen our scoops – they’re small! Our “small scoop mission” focuses on using simple formulations with minimal ingredients (especially unnecessary fillers). So, it’s really easy to increase the number of servings used per day, based on your personal needs – without worrying that you’re consuming stuff you don’t want more of. Is there anyone who needs to be concerned about their daily sodium intake? Yes! As mentioned, some people are salt sensitive, and their blood pressure increases with increased sodium consumption. Among salt sensitive people, some responses are minimal while others are quite dramatic. If you have hypertension, and especially if you know you are salt sensitive, you do want to be careful not to consume too much sodium. However, if you’re consuming a whole foods, paleo or keto diet, sodium containing supplements may still be needed to get you into a healthy range. Talk to your doctor about your individual needs. Other populations that should limit their sodium intake include people with chronic kidney disease, heart disease, diabetes, liver disease, pregnant women with preeclampsia, and people at risk of stroke. If you have these or any other serious health condition, please consult with your doctor before taking sodium containing dietary supplements. The Verdict? There is clearly controversy about how much sodium people should consume each day. Yet evidence is accumulating that intake less than 2300mg per day (as per official recommendations) may not be optimal for many people. This is suggested by the finding that only 9% of the population currently adheres to this guideline. However, excessive consumption of sodium is not recommended either, with research showing a U-shaped curve in which both very low, and very high, intakes of sodium are harmful, while the middle range of 3000 to 5000mg (or even higher) is ideal. With this target in mind, people can be mindful of their dietary patterns and include supplemental sodium, usually in the form of fluid electrolytes, as needed. Supplements that provide sodium at levels of 1000mg per serving may be ideal for certain populations (like people eating keto or paleo diets, or those losing a lot of salt through sweating), but for average men, women and children, smaller doses of sodium may be more appropriate. So, what’s the verdict? At 190mg sodium per serving, Fringe Electrolyte & Mineral Mix provides just the right amount of sodium for most people to consume one to two servings per day - and this can easily be increased for people with higher needs. An amazing tool for hydration, our mineral mix helps with fluid balance, and supports heart, muscle, nerve and blood vessel functions.

Should I Take a Vitamin D & K Supplement?
Should I Take a Vitamin D & K Supplement? The short answer to this question is, “almost definitely, yes!” Vitamin D is the “sunshine vitamin”, and since modern humans spend so much time indoors, most of us are woefully deficient in this critically important vitamin. And while vitamin D is found in some foods, surveys of dietary intake have shown that almost everyone consumes inadequate amounts. Some people are also deficient in vitamin K, and because vitamin D and K work synergistically, they should always be taken together. Read on to learn more about how these important nutrients work in our bodies to support health, and why Fringe’s unique vitamin D and K formulation is ideally designed to meet our needs. shop fringe vitamin D & K What is vitamin D & K? Vitamins are nutrients that our bodies require in small amounts for proper growth and metabolism. Since they’re required in amounts as low as milligrams (mg) or micrograms (mcg), they’re referred to as micronutrients. This contrasts with macronutrients, which are needed in larger amounts, and include carbohydrates, proteins and lipids (fats). Vitamins D and K share the unique characteristic of being fat-soluble. The absorption of fat-soluble vitamins requires dietary fat, which makes it more complex than the absorption of water-soluble vitamins. Fat-soluble vitamins are also stored in the body, while water soluble vitamins are not. Examples of water-soluble vitamins are vitamin C and the B vitamins. What is vitamin D & K? Technically, vitamins are obtained from the diet – but as already mentioned, vitamin D is the “sunshine vitamin”. While all vitamins (including D) can be ingested through food, vitamin D is also made when the skin is exposed to the UVB light from the sun. In fact, the amount of vitamin D that can be made from the sun far exceeds the amount that is normally consumed from food sources. And since UVB rays don’t pass through windows, direct sun exposure is required for vitamin D synthesis. + More Since our modern lifestyles now have us spending up to 90% of our time indoors, dietary intake of vitamin D has become really important, with dietary supplements taking centre stage. This is because it’s hard to match the amount of vitamin D made from sun exposure from vitamin D rich foods. Thirty minutes of midday sun in the summer results in the body making around 10,000 to 20,000IU of vitamin D – which is the equivalent of consuming 50 to 100 servings of sardines, one of the best food sources of vitamin D! In the absence of sun exposure, dietary supplements are really the only way to ensure that you’re consuming sufficient vitamin D to support optimal health. Vitamin D is so important that many governments recommend, and even mandate, that it to be added to certain commonly consumed foods. When vitamin D is added to food, these are called fortified foods. In the United States, vitamin D is often added to fluid milk and other dairy products, calcium fortified fruit juices, and breakfast cereals and grains. The amount of added vitamin D is usually limited to around 100IU per serving. Clearly, this falls way short of the 10,000 to 20,000IU we generate from 30 minutes in the midday sun! In addition to fortified foods, good food sources of vitamin D include egg yolks, fatty fish (such as sardines, salmon, arctic char, herring, mackerel and rainbow trout), and beef liver. Since both fortified and natural vitamin D containing foods are usually animal-based, vegans and vegetarians are more likely to be deficient. Vitamin D2 comes from plants and fungi, while vitamin D3 comes mainly from animal sources, or less commonly, non-animal sources like lichen. Fortified food may contain either form. Like vitamin D, there is also some uniqueness in terms of how we obtain vitamin K, at least one of its two forms. The two forms of vitamin K are phylloquinones (vitamin K1) and menaquinones (vitamin K2), with K2 being produced by bacteria in the human gut. Vitamin K2 produced in the gut is absorbed into the body, and does contribute to our overall vitamin K status. However, the amount produced in insufficient to meet our needs, and some dietary intake is also required. Dietary intake of vitamin K1 comes mainly from leafy green vegetables, such as spinach, broccoli, and lettuce, as well as some oils such as canola and soybean. Vitamin K2 is mainly produced by bacteria and is found in some animal-based foods like meat, dairy, and eggs, as well as fermented foods. Since K1 in plants is tightly bound to chlorophyll, it is less bioavailable than K2, with less than 20% being absorbed into the body. What do vitamins D & K do in the body? Vitamins D and K each have critical biological functions. Here’s a look at what each one does to support our health: + Vitamin D Maintains Bone Health – Vitamin D is required for the absorption of calcium from the intestine and the mineralization of bone. Supports Muscle Strength – Vitamin D increases protein synthesis in muscle cells, thereby helping to support muscle strength. Decreases Inflammation – Vitamin D is associated with reduced inflammation, at least in part by shifting the profile of immune cells from a pro-inflammatory to an anti-inflammatory state. Regulates Immune System Function – Vitamin D is a powerful regulator of the immune system, and supports protective immunity. Protects Against Oxidative Stress – Vitamin D reduces oxidative stress, and can protect cells and tissues against oxidative damage. Supports Brain Function – Vitamin D supports brain function by protecting it against damage from inflammation and oxidative stress. This “neuroprotective action” occurs across multiple regions of the brain. + Vitamin K Maintains Bone Health – Vitamin K is required for the activation of proteins involved in bone assembly, in a process known as carboxylation. Without vitamin K, these proteins remain inactive and bone structure is compromised. Regulates Blood Clotting – Vitamin K is required for proper blood clotting, also known as coagulation. Here, vitamin K activates proteins involved in the blood clotting cascade, again via the process of carboxylation. Decreases Inflammation – Vitamin K reduces the expression of pro-inflammatory molecules, which may reduce overall inflammation. Protects Against Oxidative Stress – Vitamin K has antioxidant activity that can reduce oxidative stress by inhibiting the buildup of damaging reactive oxygen species. This is a poorly understood role of vitamin K, but it may have important health implications. Regulates Glucose & Insulin Metabolism – Vitamin K helps to regulate glycemic status, affecting both glucose and insulin metabolism. This occurs via activating effects on proteins, which are dependent on vitamin K. Regulates Immune System Function – Although a minor player relative to vitamin D, vitamin K plays a role in immune system regulation, as evidenced by its ability to affect levels of certain immune cells. How do vitamin D & K work together to support health? It’s obvious from this list that vitamin D and K overlap in some of their biological roles. And it turns out that when it comes to maintaining bone health, they actually work together as a team. Simply put, vitamin D increases the absorption of calcium from the intestines into the blood, which ideally should be delivered to bones (as well as teeth). The transfer of calcium from the blood into bones first requires vitamin D dependent synthesis of specific proteins. However, these proteins are synthesized in an inactive form. This is where vitamin K comes in... + More As previously mentioned, vitamin K activates proteins involved in bone assembly, turning these inactive proteins into active ones which can then shuttle calcium into bone. In the absence of vitamin K, calcium won’t be deposited where it should be – in the bones and teeth. When calcium isn’t deposited into the bones and teeth, it is also a problem for the cardiovascular system. If calcium builds up in the blood, which is what happens when vitamin D is present without sufficient vitamin K, this calcium gets deposited in the arteries – which can cause atherosclerosis and cardiovascular disease. So, vitamins D and K must be taken together to ensure that calcium gets deposited into bones, and not arteries, and to support optimal bone and cardiovascular health. How much vitamin D & K do I need? Vitamin D The issue of optimal vitamin D intake is highly controversial. The Institute of Medicine (which sets the dietary intake recommendations for all nutrients as recognized by the US government) recommends 400 international units (IU) for children up to age 12 months, 600 IU for people ages 1 to 70 years, and 800 IU for people over 70 years. However, this recommendation only considers amounts needed to prevent serious bone disease, not to support optimal health. According to a scientific article published by authors including Harvard University’s Chair of Nutrition, the Institute of Medicine’s recommended intake of vitamin D “may be insufficient for important disease outcomes” and recommends a higher daily intake of up to 4,000IU per day, which has also been recommended as the “prophylactic” daily dose for most adults. Notably, total body sun exposure provides the equivalent of 10,000IU per day. The conflict over optimal vitamin D intake is based on disagreement over what target levels of blood vitamin D should be. While the Institute of Medicine states that 20ng/mL of 25-hydroxyvitamin D is sufficient, this is solely based on evidence related to bone health, which ignores the multitude of other biological roles for vitamin D. In contrast, the Endocrine Society recommends having blood levels over 30ng/mL, the American Association of Clinical Endocrinologists recommends 30-50ng/mL, and the D* Action Project suggests 40-60ng/mL. With so much controversy, how should the average person approach vitamin D supplementation? Our advice is to work with a health care provider who can monitor your blood vitamin D levels and tailor recommendations accordingly. Many people have genetic polymorphisms or medical disorders that affect their vitamin D levels, so it’s difficult to make blanket recommendations that apply to everyone. People also have different lifestyles, including time spent outdoors, and live at latitudes with varying sun exposure. Body weight is also an important factor for vitamin D recommendations, as is skin color. Working with a health care provider who can consider your unique variables and do appropriate lab work is the best way to ensure you meet your personal needs. Vitamin D needs will also vary depending on your level of seasonal sun exposure. In general, vitamin D needs go up in the winter months, especially for people who live at northern latitudes. Vitamin K The recommended intake for vitamin K is 120mcg for males and 90mcg for females aged 19 and over. Since disturbance of the gut microbiome (called dysbiosis) decreases intestinal vitamin K2 synthesis, people with gut issues may have increased dietary requirements for vitamin K. Am I at risk of vitamin D or K deficiency? There are several groups that are at an increased risk of vitamin D deficiency, including: Groups at an increased risk of vitamin K deficiency include: People taking blood thinners, which antagonize vitamin K People taking antibiotics, which destroy vitamin K producing gut bacteria (cephalosporin antibiotics may be especially problematic) People with malabsorption disorders including celiac disease, ulcerative colitis and Cystic Fibrosis, who have difficulty absorbing vitamin K People who have undergone bariatric (weight loss) surgery Can I take too much vitamin D & k? Vitamin D The main concern about excessive vitamin D intake is that it may increase calcium to dangerous levels. However, research suggests that hypercalcemia is unlikely to occur in healthy adults when blood vitamin D is below 700ng/mL, which far exceeds the recommended targets of 20 to 60ng/mL previously described. A 2007 scientific analysis of vitamin D intake and toxicity found no evidence of toxicity at an intake of 10,000IU per day and suggested that the currently recommended upper limit of 4000IU per day be revised. Subsequently, the Institute of Medicine revised their “No Observed Adverse Effect Level” to 10,000IU per day. Vitamin K There is no recognized upper limit to the amount of vitamin K1 or K2 that can be consumed. The Office of Dietary Supplements states that “no adverse effects associated with vitamin K consumption from food or supplements have been reported in humans or animals”. A synthetic form of vitamin K, called menadione, has caused toxicity in infants, but in the US this form is generally only used at present in animal food. What is the prevalence of vitamin D & K deficiencies? + Vitamin D The prevalence of vitamin D deficiency depends on what level of intake is targeted. The most conservative recommendation is the “official” recommendation from the Institute of Medicine, which as mentioned recommends 400IU for children up to age 12 months, 600 IU for people ages 1 to 70 years, and 800 IU for people over 70 years. Even at this low level of recommended intake, the most recent national analysis of vitamin D intake in the US found that daily intake of vitamin D from food was only 204 IU in men and 168 IU in women. This is only about a third of the Institute of Medicine recommended intake, and about 5% of the 4000IU per day recommended by other experts. At the population level, approximately 92% of men, 97% of women, and 94% of people ages 1 year and older consumed less dietary vitamin D than is estimated to meet the needs of at least half the US population. Many people do take vitamin D supplements, which increases the overall observed combined daily intake from food and supplements to 692 IU in men and 1204 IU in women, with more women taking supplements than men. Supplements are clearly helpful at increasing daily vitamin D intake, but at the current level of supplementation most people still fall well short of the higher intakes recommend by some experts. + Vitamin K The average daily intake of vitamin K according to the most recent national dietary analysis shows that men consume 118mcg and women consume 121mcg. This increases to 125mcg and 129mcg for men and women, respectively, when vitamin K supplements are also considered. These results show that most people are meeting their recommended daily intake of vitamin K intake. However, low levels of vitamin K intake have been observed in older adults, where they are associated with an increased death rate. These results show that most people are meeting their recommended daily intake of vitamin K intake. However, low levels of vitamin K intake have been observed in older adults, where they are associated with an increased death rate. Because increasing intake of vitamin D results in the synthesis of proteins that must be activated by vitamin K to prevent deposition of calcium in the arteries, vitamin K should always be supplemented along with vitamin D, regardless of whether dietary intake is sufficient. Especially considering that there is no upper limit of intake for vitamin K, combining these two vitamins in a supplementation regimen is prudent. What are the health risks of vitamin D deficiencies? Identification of health risks from having low vitamin D depends in part on what value of blood vitamin D (specifically, 25-hydroxyvitamin D) is determined as the level of deficiency. The “deficiency level” ranges from less than 12ng/mL to less than 30ng/mL, depending on which organization you follow. This will reflect a wide range of dietary and supplemental vitamin D intake. Because of this variation, the health risks of vitamin D deficiency will vary based on the deficiency level cutoff being used. + More If we broadly consider vitamin D deficiency to include anything below 30ng/mL of 25-hydroxyvitamin D, some of the associated health risks are: Loss of calcium from bones and increased risk of osteoporosis Increased risk of bone fractures Reduced muscle strength and increased risk of falling Increased blood markers of inflammation Increased risk of autoimmune disease, such as inflammatory bowel disease Increased susceptibility to infection Increased risk of dental cavities Increased risk of cancer Increased oxidative stress and related diseases such as diabetes and cardiovascular disease Increased risk of brain diseases such as dementia and depression Low circulating levels of vitamin D have also been associated with an increased risk of death from all causes, called “all-cause mortality”, as well as deaths from cardiovascular disease and can What are the health risks of vitamin k deficiencies? Although rare, vitamin K deficiency is associated with several notable health risks, including: Increased risk of osteoporosis Increased risk of bleeding disorders Increased risk of diseases with an inflammatory component, such as diabetes Increased risk of cardiovascular disease Low circulating levels of vitamin K have also been associated with a 19% increased risk of all-cause mortality. How could taking a vitamin D & K supplement help me? Vitamin D Multiple scientific studies show benefits from taking supplements of vitamin D. These include: Reduced incidence of viral infections Reduced incidence of dental cavities Reduced incidence of cancer (when administered daily) Reduced symptoms of Polycystic Ovary Syndrome (PCOS) Increased bone mineral density (when supplemented with calcium) Reduced risk of falling (especially when combined with calcium) Reduced depressive symptoms Reduced mortality in critically ill patients Improved blood markers in patients with ulcerative colitis Reduced insulin resistance in non-diabetic pregnant women Reduced C-reactive protein, a biomarker of inflammation Reduced systolic blood pressure Reduced exercise-induced muscle cell damage Improved non-verbal memory in healthy adults Improved glycemic control in diabetics Vitamin K For vitamin K, scientific studies also show benefits of supplementation, including: Decreased risk of bone fractures Improved bone mineralization and strength Reduced risk of developing diabetes Improved glycemic control Reduced C-reactive protein, a biomarker of inflammation Reduced wound healing time (when applied topically) Reduced symptoms of peripheral neuropathy (in patients with vitamin B12 deficiency or Type II Diabetes) Improved markers of cardiovascular disease Importantly, supplementation with vitamin K2 and vitamin D in combination has shown positive effects on bone mineral density when compared to a control group eating a regular diet. Should I take a calcium supplement when taking vitamin D & K? One of the main effects of vitamin D is to increase calcium absorption from the intestine, which – along with vitamin K – will allow calcium to be deposited into bone. But for this to occur, dietary or supplementary calcium must be ingested as well, or else there won’t be any calcium present to absorb! + More Some research has shown that bone mineral density improves when taking vitamin D supplements, provided it is taken along with calcium. Research has also shown that supplementation with vitamin D and calcium reduces the risk of total fractures by 15%, and the risk of hip fractures by 30%. However, not all studies have shown these benefits, leading some researchers to conclude that taking calcium (with vitamin D) for the prevention of osteoporosis and fractures is unwarranted. Some research has also suggested that taking supplemental calcium can have adverse effects on the cardiovascular system. This has led to a debate over whether taking calcium supplements to prevent osteoporosis has more benefits than risks. There’s no doubt, however, that calcium is an essential mineral. Ideally, it should be obtained from foods, such as dairy foods, almonds, and sardines. A little-known fact is that natural water also often contains calcium, which is removed with many modern filtration systems. Drinking calcium-rich mineral water in place of filtered water can be source of dietary calcium intake. Interestingly, the daily target range of calcium intake from diet and/or supplements varies widely among health organizations, from a minimum of 400mg to up to 1300mg per day, depending on age and gender. These recommendations have also changed across time, which shows a lack of clarity regarding optimal intake. If you consume very little calcium in your diet, then taking a supplement may be warranted. Many supplements on the market are quite high in calcium, with 500-1000mg per serving. These should be avoided. It’s better to take a supplement that more closely mimics dietary intake, at 250mg or less. If your calcium intake is extremely low, a low dose supplement could be taken 2 to 3 times per day. Are there nutrients other than calcium and vitamin K that interact with vitamin D? Yes! Magnesium is another nutrient that is interacts with vitamin D. Many enzymes that synthesize and metabolize vitamin D are dependent on magnesium for proper functioning, so optimal magnesium status is important for vitamin D. Most people do not consume sufficient dietary magnesium, and due to depletion of magnesium from our soil and foods, supplementation may be necessary to meet our daily needs. Vitamin A is another nutrient that interacts with vitamin D. Some vitamin D binds to vitamin A, forming a unit called a “heterodimer”. This A/D heterodimer can regulate the expression of many different genes, including several involved in bone health. Vitamin A is found in foods like liver, fish, eggs, and dairy, while pre-vitamin A (also known as carotenoids) are found in plant foods like leafy greens, peppers, and carrots. Ensuring adequate intake of vitamin A is important when supplementing with vitamin D. Vitamin A can be consumed through foods and supplements, and it is also added to some foods (like breakfast cereals) via fortification. Survey data has shown that 22% of the US population suffers from vitamin A deficiency, while 33% consume an excess. Since there are serious risks (like birth defects) associated with taking too much vitamin A, widespread supplementation is not recommended, although it is certainly warranted in some cases. shop fringe vitamin D & K What should I look for in a vitamin D & K supplement? (1) Read the ingredients – Most dietary supplement will contain both active and inactive or “other” ingredients. You need to pay attention to both. The active ingredients are the ones that you are looking for, and a vitamin D and K supplement will contain at least one form of each as an active ingredient. Choose the form that best meets your needs (see #3 in this list for more details!). Although this information may be hard to find, it’s helpful to know where these active ingredients are sourced from. Naturally sourced ingredients are always better than artificial ones. + More The inactive ingredients are usually there to: (1) provide bulk (filler), (2) hold the product together (binding agents, coatings), (3) add flavor or sweetness, or (4) keep the product from clumping together (flow enhancers). Sometimes this list is long, and it’s often where some undesirable ingredients sneak in, such as potassium sorbate, artificial colors, or titanium dioxide. It’s best to keep this list short and naturally sourced. (2) Verify product purity – Only choose high quality products that verify their purity via an unbiased chemical analysis performed by a third-party lab. These analyses should be reported in a Certificate of Analysis (COA) that is readily available to consumers, often through a QR code link. COA’s should be available for each batch of products, and will measure contaminants such as heavy metals, microbes, and pesticides. (3) Consider the form(s) of vitamin D & K in the supplement – There are two forms of vitamin D that are found in dietary supplements, vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D3 is sourced mainly from animals, although lichen is a vegan source of D3. Vitamin D3 is the form made in humans following exposure to UVB light. In contrast, vitamin D2 is sourced from plants. Vitamin D3 is largely recognized as being more “bioavailable”, meaning more of the vitamin that is ingested gets delivered to body tissues. Studies that directly compare the bioavailability of D3 to D2 show that vitamin D3 raises blood levels of 25-hydroxyvitamin D more than vitamin D2, so it is preferable to choose a supplement containing vitamin D3. If you are vegan, choose a supplement that contains D3 sourced from lichen. As previously described, there are also two forms of vitamin K, vitamin K1 (phylloquinone) and vitamin K2 (menaquinones). Vitamin K1 comes mainly from plants, while vitamin K2 is made by bacteria and is found in animal-based and fermented food. Vitamin K2 is further subdivided into MK-4 through MK-13. Each of these subgroups of vitamin K2 has a slightly different molecular structure. Dietary supplements usually include MK-4 or MK-7. MK-4 occurs naturally in foods including liver, butter, and cheese, while MK-7 is made through fermentation, with the best source being Japanese fermented soybeans (called Nattō). Studies have shown that vitamin MK-7 is more bioavailable than vitamin MK-4, so it is preferable to choose a supplement containing vitamin MK-7. (4) Choose the supplement form you prefer – Supplements come in three main forms: capsules/tablets, powders, or liquids. Which one you choose is really a personal preference. Powders and liquid can be added to liquids, like smoothies, and are a great option if you don’t like swallowing pills. How is Fringe Essentials Vitamin D & K different from other supplements? Fringe Essentials Vitamin D & K has three highly unique attributes that make it superior to other products on the market: + Water Solubility Water Solubility – We’ve already covered that both vitamin D and K are fat-soluble vitamins. The absorption of fat-soluble vitamins is complex, which results in a lower bioavailability than water-soluble vitamins (recall that bioavailability refers to how much of the ingested nutrient is delivered to body tissues). The bioavailability of fat-soluble vitamins can be increased significantly through a safe and simple conversion process that makes them water-soluble and able to readily be absorbed through the walls of the small intestine. Research has demonstrated that water-soluble vitamin D is about twice as bioavailable as fat-soluble vitamin D. Another advantage to making vitamin D and K water-soluble is that it will eliminate the competition that occurs for the absorption of fat-soluble vitamins. And when you supplement with water-soluble vitamin D and K, you don’t need to consume them with food (especially food that contains some fat) to optimize absorption, like you do with fat-soluble vitamins.As a water-soluble powder, Fringe Essentials Vitamin D & K can be added to any liquid where it will dissolve easily without residue. + Vegan D3 Vegan D3 – Research has clearly demonstrated that vitamin D3 is superior to vitamin D2 at raising blood levels of 25-hydroxyvitamin D. The vast majority of vitamin D3 supplements source the vitamin from sheep’s wool, which produces a waxy substance called lanolin. Lanolin is extracted from sheep’s wool and put through a process which creates and extracts vitamin D3 using UVB light and chemical solvents. Because it is animal based, lanolin-derived vitamin D3 is not suitable for vegans. Fringe Essentials Vitamin D & K uses the only vegan source of vitamin D3, which is lichen. Lichens are living organisms that consist of fungus combined with algae or cyanobacteria. Lichen also make vitamin D3 following exposure to UVB. Lichen-derived vitamin D3 is identical to that produced from sheep’s wool, but is non-animal based, making it suitable for everyone. + Vitamin MK-7 Vitamin MK-7 – Fringe Essentials Vitamin D & K contains vitamin MK-7, the most bioavailable form of vitamin K. It is derived from the fermentation of Nattō, which is plant-based and suitable for vegan diets. The other ingredients in Fringe Essentials Vitamin D & K water-soluble powder are all natural and non-GMO. They include inulin and myo-inositol (also sometimes called vitamin B8) to help with dosing, medium chain triglyceride (MCT) oil to help with emulsification, and licorice extract for increased bioavailability. Dosing & Safety Fringe Essentials Vitamin D & K contains 2500IU of vitamin D3 and 130mcg of vitamin K2 (as MK-7). Because our vitamins are water soluble, they are more readily absorbed than most vitamin D and K supplements on the market, which means you don’t need to take as much to have the same effect. + Learn more For adults, we recommend using 1 scoop of Fringe Essentials Vitamin D & K per day as a maintenance dose when sun exposure is limited. A maintenance dose is meant to maintain blood levels of 25-hydroxyvitamin D within the range of 40-60ng/mL. However, if your blood vitamin D is very low, it may be necessary to take more until you reach this target range. The only way to know for certain how your body is responding to supplementation is to have your blood tested. This inexpensive test can be ordered by your health care provider, and home testing kits are also available. Lesser amounts can be taken when direct sun exposure is higher because skin synthesis of vitamin D will be much higher. Kids can also take Fringe Essentials Vitamin D & K. Based on age, the recommended doses are: for children aged 1-3 years old, ¼ scoop per day; ages 4-8, ½ scoop per day; ages 9-13, ¾ scoop per day; ages 14+, 1 full scoop per day. As with adults, the only way to know for certain how a child is responding to supplementation is to have their blood tested. For children under 1 year of age, please consult a health care provider before using. Vitamin D and K are safe to take when pregnant and breastfeeding. Of course, consult your doctor before beginning a supplement regimen. Fringe Essentials Vitamin D & K is incredibly safe. We use high quality ingredients and test every batch of our final product to ensure safe levels of toxic ingredients, including heavy metals, molds, and pesticides. We also leave out all the stuff you don’t want like artificial sweeteners, additives, gums, and ‘natural flavors’. Is there anyone who should not take a vitamin D & K supplement? One group that needs to be cautious about vitamin K supplementation is people taking anticoagulant, or blood thinning, medications. Taking high levels of vitamin K when on anticoagulants can decrease the effectiveness of the drug, which could increase the risk of blood clot formation. This is because of vitamin K’s important role in the blood clotting cascade. To recap Vitamin D deficiency is rampant in modern society. Sunshine provides us with a free and natural source of this essential vitamin, but on average, we spend 90% of our time indoors, leaving this vital resource untapped. Since it’s difficult to consume enough vitamin D from the diet, adding a high-quality supplement to your daily health regimen is an easy fix. Fringe Essentials Vitamin D & K combines vitamin D with vitamin K, a duo that is needed for optimal bone and cardiovascular health. In contrast to most supplements on the market, ours is water-soluble, which means more of it gets to where it’s needed. It’s also naturally sourced, non-GMO, and vegan – containing only what you need, without unnecessary additives and fillers. Simply mix 1 scoop of Fringe Essentials Vitamin D & K into your water, smoothie, coffee, tea, or favorite beverage daily. You can also take a bit more or less, depending on the season and your unique needs! The contents in this blog; such as text, content, graphics are intended for educational purposes only.

Red Light Therapy vs Ice
Red Light Therapy vs Ice. If you were to take a sample of doctors and athletic trainers and ask them what therapy they recommend that people use for post-exercise muscle recovery, you are guaranteed to find that a majority will tell you to apply ice. Cryotherapy or icing has long been considered the gold standard for dealing with pretty much any kind of inflammatory process, including the muscle inflammation that occurs following strenuous exercise. Cryotherapy is a therapeutic technique that involves exposing the body or specific areas to extremely cold temperatures, typically using ice packs, cold water immersion, or specialized cryochambers. But research has now clearly shown that when you put icing head-to-head with Red Light Therapy – which uses red and/or near infrared light to influence biology - and look at which one works better to support exercise recovery, Red Light Therapy consistently comes out on top. In 2019, a scientific article was published that reviewed three clinical trials and two animal studies comparing cryotherapy to Red Light Therapy. Each human clinical trial administered both red and near infrared light, while the two animal studies used near infrared light only, and light or cryotherapy were applied following exercise. The outcome for each study was post-exercise muscle recovery. All five studies found that Red Light Therapy was superior to cryotherapy at improving outcomes related to exercise recovery. This included decreased delayed onset muscle soreness and reduced muscle inflammation. The research also showed that in contrast to Red Light Therapy, cryotherapy did nothing to prevent muscle damage from occurring following strenuous exercise, since markers of muscle damage like creatine kinase were only reduced with Red Light Therapy. The superiority of Red Light Therapy over cryotherapy makes perfect sense when you consider the mechanisms of how the two modalities work. In a nutshell, red light therapy stimulates mitochondria to produce energy and modulate oxidative stress, decreasing cellular markers of inflammation. Red Light Therapy also induces cellular changes like increasing the production of growth factors. This is how it can have effects such as decreasing inflammation and healing damaged muscle fibers, and how it can positively influence many aspects of exercise recovery. In contrast, cryotherapy constricts blood vessels and decreases blood flow, which leads to less edema formation (swelling). This might reduce inflammation and decrease pain, but it really does nothing on a cellular level to support healing. In fact, it’s been argued by some experts to do the opposite. Several criticisms of cryotherapy have been raised, including that it only provides temporary relief and does not promote long-term healing. The studies described in this analysis used light that was quite low in intensity. Light intensity refers to the amount of light being delivered by a device. It is also sometimes called irradiance, and it’s usually measured in units called mW/cm2. Red Light Therapy devices on the market vary widely in terms of their intensity. While it’s common to see marketing claims that high intensity products (at upwards of 100mw/cm2) are needed to reap the benefits of Red Light Therapy, this research (and a lot of other studies too), show that this is false. When it comes to using Red Light Therapy for post-exercise muscle recovery, research has clearly shown that more is not better. Instead of high intensity products, it’s best to use a device that delivers both red and near infrared light at a low to moderate intensity. Fringe Red Light Therapy products are great options for post-exercise support, delivering the optimal intensity of light at between 20 and 40mw/cm2. This is like the intensity of the sun. Fringe Red Light Therapy wraps even have the advantage of being portable and cordless, offering the flexibility of immediate use, including on the sideline! So, the next time you have a hard workout, reach for a Red Light Therapy device instead of ice to support muscle healing. And the advantages of Red Light Therapy over cryotherapy extend to healing for other conditions as well. Basically, you can use Red Light Therapy for anything that you would consider using ice for. By using Red Light Therapy instead, you’ll not only decrease pain and inflammation, but you’ll also activate cellular healing mechanisms that will help you to feel better faster.

Should I Take a Magnesium Supplement?
Should I take a magnesium supplement? The simple answer to this question is: Most likely, yes. Scientific evidence suggests that many people are at risk of magnesium deficiency, even those consuming a healthy diet. There are many reasons for this, most of which are out of our control. Given the critical importance of magnesium in the human body, and the significant health risks that accompany even a subclinical magnesium deficiency, regular supplementation with a high-quality dietary supplement is a wise investment in your health. shop fringe magnesium What is Magnesium? Magnesium is one of the most abundant minerals, both in the earth and inside the human body. Most magnesium in the body is found inside cells, rather than in the blood, and it is especially concentrated in the muscles and bones. In the body, magnesium carries a positive charge, and is therefore referred to as an ion or electrolyte. The recommended intakes of magnesium have been determined and are based on age and gender. These values are known as the dietary reference intakes (DRI’s). Recently, it has been suggested that the DRI’s for magnesium are too low because they haven’t been adjusted for rising body weights. The new estimates recommend an additional intake for adults of between 60-235mg magnesium per day beyond what is shown in table 1. What does magnesium do in the body? Magnesium is involved in virtually every cellular metabolic and biochemical process in the human body. As a cofactor or activator for over 800 chemical reactions, magnesium regulates everything from metabolism to protein synthesis, to DNA repair and synthesis. It is also involved in conveying messages between molecules within the cell as well as in regulating cell replication. What are good sources of magnesium? Magnesium is found in many foods, both plant and animals. Some good sources of magnesium are: Green leafy vegetables Legumes Nuts Seeds Whole grains Good sources of magnesium should contain around 40-80mg per serving. Meat, dairy and fruit also contain some magnesium but at lower amounts. A general rule of thumb is that the more highly processed a food, the less magnesium it will contain (unless it has been fortified). Although there are many food sources of magnesium, a drastic loss of magnesium from agricultural soil over the last century has led to a decrease in the magnesium content of plant foods due to their inability to absorb sufficient magnesium from the earth. For example, the magnesium content of vegetables has decreased by 80-90% over the last century. As a result, supplementation with magnesium may be necessary to avoid deficiency. What is the prevalence of Magnesium deficiency? There are two types of nutrient deficiencies, frank and subclinical. Frank deficiencies have obvious signs, while subclinical deficiencies do not. Frank deficiencies of magnesium are rare because the kidneys can limit its excretion. But subclinical deficiencies are extremely common, since over half of the US population don’t consume the recommended amount. In fact, according to a research article in the Open Heart medical journal, “the evidence in the literature suggests that subclinical magnesium deficiency is rampant and one of the leading causes of chronic diseases including cardiovascular disease and early mortality and should be considered a public health crisis.” What are the causes of Magnesium deficiency? As already described, two of the main causes of magnesium deficiency are (1) low intake of dietary magnesium, and (2) a substantial loss of magnesium from agricultural soil causing a decrease in the magnesium content of foods. These two issues will be compounded, such that even when people attempt to consume sufficient dietary magnesium, they may be unable to. There are also several other factors that increase the risk of magnesium deficiency. These include: Magnesium also interacts with other nutrients, which can increase the risk of deficiency. For example, taking high doses of vitamin D can increase the loss of magnesium from the body, while taking high doses of zinc can interfere with magnesium absorption. High doses of fiber can also interfere with magnesium absorption. What are the health risks of Magnesium deficiency? Because of its nearly ubiquitous role in the body’s processes, low levels of magnesium can create widespread physiological dysfunction. And because of the widespread incidence of low magnesium intake, magnesium deficiency is recognized as an important global concern. A frank magnesium deficiency will manifest with clinical signs, including: Low appetite Nausea and vomiting Fatigue and weakness Muscle spams or tremors Abnormal heart rhythm Convulsions Psychiatric disturbances But because the kidneys regulate the excretion of magnesium from the body, it’s rare to have magnesium be depleted to the point where these potentially life-threatening symptoms occur. Far more common is subclinical magnesium deficiency, which often does not have obvious signs. Because it’s so easy to under consume magnesium, and since the signs of subclinical magnesium deficiency are hard to spot, it often extends over time leading to long-term adverse complications. These include a wide range of health problems and chronic diseases, including: Cardiovascular diseases Diabetes Migraines Osteoporosis Asthma Metabolic disorder Alzheimer’s Disease Parkinson’s Disease Premenstrual Syndrome Dysmenorrhea These conditions have potentially devastating consequences, which makes magnesium a critical nutrient of concern for public health. How could taking a magnesium supplement help me? There are both long-term and short-term benefits to ensuring adequate magnesium intake, which for many people, will require taking a magnesium supplement. As just described, there is a long list of health problems and chronic diseases associated with a long-term subclinical magnesium deficiency, many of which can be helped by taking a magnesium supplement. Can I take too much magnesium? Magnesium toxicity is mostly seen with consumption of high doses of magnesium containing laxatives and antacids. Consumption of more than 5000mg per day can cause toxicity, with symptoms including low blood pressure, nausea, vomiting, muscle weakness, and even cardiac arrest. It would be nearly impossible to consume this much magnesium through dietary supplements, which usually contain less than 300mg per serving, and totally impossible through food. Because the excretion of magnesium is regulated by the kidneys, it is difficult to take too much, and is not a concern except with consumption of magnesium containing medications. How do I choose a Magnesium supplement? Read the ingredients - Most dietary supplement will contain both active and inactive or “other” ingredients. You need to pay attention to both. The active ingredients are the ones that you are looking for; for example, a magnesium supplement will contain at least one form of magnesium as the active ingredient. Some supplements, like multi-vitamins, have many active ingredients. Usually, these are vitamins, minerals, of phytochemicals derived from plants. Although this information may be hard to find, it’s helpful to know where these active ingredients are sourced from. Naturally sourced ingredients are always better than artificial ones. The inactive ingredients are usually there to: (1) provide bulk (filler), (2) hold the product together (binding agents, coatings), (3) add flavor or sweetness, or (4) keep the product from clumping together (flow enhancers). Sometimes this list is long, and it’s often where some undesirable ingredients sneak in, such as potassium sorbate, artificial colors, or titanium dioxide. It’s best to keep this list short and naturally sourced. Verify product purity – Only choose high quality products that verify their purity via an unbiased chemical analysis performed by a third-party lab. These analyses should be reported in a Certificate of Analysis (COA) that is readily available to consumers, often through a QR code link. COA’s should be available for each batch of products, and will measure contaminants such as heavy metals, microbes, and pesticides. Consider the form(s) of magnesium in the supplement – There are several different forms of magnesium that are included in dietary supplements, each of which has unique properties. Look for ones that are bioavailable and easy on digestion. The forms of magnesium that are most likely to cause diarrhea are magnesium chloride, carbonate, oxide, and gluconate. Magnesium malate shows high bioavailability compared to the commonly supplemented forms of magnesium oxide and magnesium citrate. Other organic forms of magnesium such as magnesium glycinate and magnesium orotate also show high bioavailability. Some forms of magnesium have also shown unique health benefits; for example, magnesium orotate helps with cardiovascular and gut health. While all magnesium supplements can help to prevent magnesium deficiency, some forms may be better suited to your unique needs. Choose the supplement form you prefer – Supplements come in three main forms: capsules/tablets, powders, or liquids. Which one you choose is really a personal preference. Powders and liquid can be added to liquids, like smoothies, and are a great option if you don’t like swallowing pills. Fringe Essentials Magnesium Powder The Fringe Essentials Magnesium Powder contains three forms of magnesium: orotate, malate, and glycinate, at 173mg total and 41% of the recommended Daily Value. These forms of magnesium have been shown to be better absorbed into the body, and they’re easily digested. Each one has unique health benefits that make them well suited to not only ensure sufficient magnesium intake, but also to reap a wide range of health benefits. Here’s what they do: + magnesium glycinate: Magnesium glycinate is a standout in helping to reduce anxiety, promote relaxation, support deep sleep, reduce muscle tension, and balance mood. _____________________________________ + magnesium orotate: Magnesium orotate is one of the best forms of magnesium to consume for heart health. It’s been shown to help with hypertension and heart disease, and to reduce risks of heart attacks. It also supports gut and mental health and helps with exercise recovery. It may even be helpful in diabetes and Alzheimer’s Disease. _____________________________________ + magnesium malate: Magnesium malate is great for chronic pain, inflammation, energy production, and muscle tension and recovery. _____________________________________ The other ingredients in Fringe magnesium powder are all natural, and include non-GMO inulin to help with dosing, organic monkfruit extract for a bit of natural sweetness, and vitamin C for an antioxidant boost. Simply mix 1 scoop of magnesium into your water, smoothie, or favorite beverage 1-2 times per day. shop fringe magnesium

Should I Take an Electrolyte Supplement?
The simple answer to this question is: Most likely, yes. The story of fluid-based electrolytes is very much a story of water – which as you will see, has changed dramatically in the last few decades. As water processing has evolved to remove harmful contaminants, essential nutrients (in the form of minerals) have also been lost, with potentially negative consequences. In this article, you’ll learn about the role of fluid-based mineral electrolytes in supporting human health, and how this has changed across time. shop fringe electrolytes How has the composition of drinking water changed across time? When most people think of water, they think of the water molecule: H2O. What many people don’t realize is that water in nature also contains a wide range of nutrients in the form of dissolved minerals. As it travels over rocks and through the earth, minerals make their way into water. The result is complex fluid matrix that is far more than just H2O. The nutrients (minerals) commonly found in natural water include: Sodium Potassium Magnesium Calcium Trace minerals, such as selenium, iodine, molybdenum, zinc, copper, manganese, and chromium. Unfortunately, the water that is accessible to most humans on earth also contains a wide range of potentially harmful contaminants. While developing countries experience the greatest contamination, water in developed countries also often contains contaminants of concern. For example, tap water in the US often contains things like lead, arsenic, and industrial and agricultural contaminants. Removing these contaminants is critical to supporting human health. To remove these undesirable compounds, water filtration devices are used. These devices pass water through a semi-permeable filtration membrane, and range in complexity from simple pitchers and countertop basins to industrial reverse osmosis filtration systems. Reverse osmosis filtration is also widely used in government, commercial, and military applications. Filtration devices do not distinguish between minerals such as magnesium, which are essential for human health, and harmful contaminants such as lead. The filters are non-specific and remove any molecules bigger than the size of the filtration pores, which include naturally occurring minerals. As a result of this processing, our modern filtered water becomes simple H2O. Should water be a source of essential nutrients? A little-known fact is that consumption of water from nature will make a small (but appreciable) contribution to our required nutrient intake, specifically the intake of some minerals, which are a class of micronutrient. Most commonly, recommended nutrient intake is defined using the Recommended Dietary Allowance (RDA), which refers to nutrients that come from food. But this term is a bit of a misnomer, as it ignores nutrient intake from water. Instead, the World Health Organization recommends that we use the term Recommended Nutrient Intake (RNI, also referred to as the Reference Nutrient Intake), which refers to nutrients that come from food and water. As already mentioned, there are many nutrients that occur naturally in water, including calcium, magnesium, sodium, chloride and potassium. These minerals are estimated to contribute between 1 and 20% of our recommended daily intake values when natural water is consumed. Water makes the most appreciable contribution to nutrient intake for calcium and magnesium, at up to 20%, while for most other minerals it provides between 1 and 5%. By removing minerals from water using processes such as reverse osmosis, we are eliminating a vital nutrient source. Putting minerals back into water, which can be done with electrolyte mineral formulations, is an easy way to circumvent this problem. Are there any health impacts of drinking highly filtered water? While it’s obviously important to remove harmful contaminants from water, this can’t be done without also removing essential nutrients. And there is clearly a downside to this removal. Here are a few important health risks that have been associated with drinking highly filtered water: Mineral loss from the body: Studies have shown that consumption of demineralized water can lead to a loss of body minerals that are excreted in the urine, faces and sweat. In kids, this can slow growth and lead to cavities. Water loss from the body: In addition to mineral losses, drinking demineralized water also leads to the loss of water from the body - there is an up to 20% increased excretion of body water in studies of human volunteers drinking demineralized water. Impaired electrolyte homeostasis: Drinking demineralized water may impair electrolyte homeostasis and lead to changes that may increase the risk of cancer. There is also some evidence of mineral intake specifically from water preventing disease in humans. For example, magnesium in drinking water is associated with protection against death from acute myocardial infarction (heart attack) among males. Similarly, drinking hard water (which contains dissolved electrolytes, including calcium and magnesium) is associated with protection against cardiovascular disease. Drinking hard water has also been associated with a decreased risk of some types of cancer, including stomach and esophageal, as well as stroke. Calcium rich water has also been found to support bone health. What are electrolytes? You’ve probably already realized that the minerals found in natural water have something to do with electrolytes. In fact, many of these minerals are electrolytes. Electrolytes are minerals that carry an electric charge and can conduct electricity in the body when in a dissolved state. The most important electrolytes in the body are sodium, potassium, chloride, magnesium, calcium, phosphorous, and bicarbonate. These charged ions are found throughout the body, and their levels are carefully maintained in balance, or homeostasis. What do electrolytes do in the body? The general role of electrolytes is to regulate physiological function, but each one is unique. Here is an overview of the primary electrolytes and their specific roles in the body. Why can’t I just consume electrolytes from food and supplements? Electrolytes have two sources in nature, food and fluids (especially water). And in modern society, we’ve added a third: dietary supplements. Both food and dietary supplements are good sources of electrolytes and should comprise the majority of nutrient intake. However, water can provide between 1 to 20% of certain minerals, and it is abundantly clear that consumption of electrolytes from water yields unique benefits irrespective of food and supplement consumption, including protection against: Mineral losses from the body Water losses from the body Some types of cancer Stroke Cardiovascular disease Consumption of electrolyte containing water also supports the maintenance of electrolyte homeostasis in the body, which is essential for optimal physiological function. Water that contains electrolytes is obtained in one of two ways: by drinking natural mineral rich water, or by adding a mineral rich electrolyte supplement to a demineralized water source, such as reverse osmosis water. Can electrolytes become deficient or imbalanced? Electrolyte imbalances can occur when blood levels become too high, or too low. Each electrolyte can become imbalanced, with potentially serious (and even life threatening) consequences. Levels of electrolytes are tightly regulated in the body for this reason, which occurs mainly at the level of the kidneys. Electrolyte deficiencies occur when there is Inadequate dietary consumption of a nutrient. Both imbalances and deficiencies are possible. Do some people need more electrolytes? Yes, there are some people who need more electrolytes. Anyone who – for whatever reason – is losing fluid from the body at a higher-than-normal rate will need to intake more to restore electrolyte balance. And anyone consuming low levels of electrolytes from food and water will require more to prevent deficiency. This applies to the following conditions: People who are exercising and sweating (even more so if in hot and/or humid conditions). People eating a low sodium diet, such as keto, paleo, or other low carb diets. Note – if you are on a low sodium diet because of a medical condition, such as a kidney disease, be cautious about supplemental sodium intake. People who are fasting. People experiencing illnesses involving vomiting and diarrhea. People with certain medical conditions, such as Postural Orthostatic Tachycardia (POTS) Increasing intake of mineral rich water, either natural or supplemental, as well as consuming more electrolyte containing foods, can help people meet these increased needs. How do I choose a mineral electrolyte supplement? Read the ingredients – Most dietary supplement will contain both active and inactive or “other” ingredients. You need to pay attention to both. Electrolyte supplements should contain several electrolytes, such as sodium, magnesium, chloride, and potassium, as the active ingredients. Although this information may be hard to find, it’s helpful to know where the active ingredients are sourced from. Naturally sourced ingredients are always better than artificial ones. For example, in an electrolyte supplement, a natural source of sodium and chloride would be natural sea salt. Electrolyte supplements usually also contain inactive ingredients. The inactive ingredients are usually there to: (1) provide bulk (filler), (2) hold the product together (binding agents, coatings), (3) add flavor or sweetness, or (4) keep the product from clumping together (flow enhancers). Sometimes this list is long, and it’s often where some undesirable ingredients sneak in, such as potassium sorbate, artificial colors, or titanium dioxide. It’s best to keep this list short and naturally sourced. Verify product purity – Only choose high quality products that verify their purity via an unbiased chemical analysis performed by a third-party lab. These analyses should be reported in a Certificate of Analysis (COA) that is readily available to consumers, often through a QR code link. COA’s should be available for each batch of products, and will measure contaminants such as heavy metals, microbes, and pesticides. Look at the amounts listed in the Nutrition Facts – Electrolyte supplements are not meant to provide high levels of the daily value of nutrients, so when you look at a Nutrition Facts table, the %DV (Daily Value) for each nutrient should be twenty or less. Minerals from natural water will be between 1 and 20% DV, so this is a simple rule of thumb to follow. An additional consideration is that if an electrolyte supplement can be added to water, rather than being pre-packaged in plastic bottles, contamination of the water with microplastics can be reduced. What's NOT in fringe electrolytes? Let’s start off describing what we’ve (intentionally) left out of Fringe electrolytes. They contain no: What's in the tub? Sodium Chloride from Sea salt: Sea salt provides both sodium (at 8%DV) and chloride (at 20% DV). It also contains small amounts of other minerals like iron, iodine, manganese, zinc, and selenium. We opted for a high-quality natural sea salt, sourced from Australian sea water, rather than table salt, because of its natural origin and more diverse mineral profile. Calcium from Calcified Algae Calcium is essential for supporting bone and teeth health, but also important for muscle and nerve function. Potassium: Potassium (at 2% DV) is essential for regulating many processes in the body, including heart, muscle, nerve, and blood vessel function. Magnesium from magnesium malate: Magnesium malate (at 3% DV) is a highly absorbable form of magnesium that helps reduce pain and inflammation, improve mood, and supports heart, nerve, and muscle health – without causing unpleasant digestive symptoms. Trace minerals: We wanted to up the ante on our electrolytes and supplement trace minerals – essential micronutrients which are critical in many biological processes in the body! Our trace minerals are naturally sourced from the Great Salt Lake and include selenium, iodine, molybdenum, zinc, copper, manganese, and chromium. These are present in small amounts that are below 1% DV. *Our ratio of sodium to potassium is at around 3:2, which is the same ratio used by the sodium potassium pump. Non-GMO Inulin: This is a soluble fiber derived from chicory root. It helps to maintain accurate dosing with the product and is also a prebiotic resistant starch which has a positive effect on gut health! shop fringe electrolytes Recap We’ve covered a lot of ground in this article, but the key takeaway is that mineral rich electrolyte supplements will help to support hydration and electrolyte balance. Adding minerals to water at between one and 20% of the recommended daily nutrient intake will restore your water to the way that nature intended. An easy way to do this is by using Fringe electrolytes as a regular part of your wellness routine. Simply mix 1 scoop of electrolyte powder into your water, 1-2 times per day. For a bit of natural flavor, add a squeeze of citrus or a few drops of essential fruit oil. Add a boost of hydration in the morning to start your day right, rehydrate after a tough workout, throw in your kiddos water to keep them hydrated in a clean way…there’s no right or wrong way to do it!

Light Therapy for Inflammation
Inflammation is one of the most popular topics in healthcare, and rightfully so. It is a hallmark of many diseases currently ravaging modern society, such as arthritis, ulcerative colitis, inflammatory bowel disease, heart disease, diabetes, cancer, Alzheimer’s Disease, and depression. Inflammation is also associated with acute diseases involving the heart, pancreas, liver, and other organs, as well as trauma and infection. The personal and economic burden of these diseases cannot be overstated. Treatment of inflammation associated diseases makes up the majority of health care spending in the US, costing billions of dollars annually. There are also indirect costs of illness, such as reduced work and productivity. The most common treatments for inflammation are pharmaceuticals, including prescription (such as Celebrex) and the over-the-counter drugs (such as Aspirin and Alleve). However, many of these drugs have serious side effects, such as hypersensitivity reactions and ulcers. Given these risks, many people are turning to non-invasive therapies to fight inflammation, some of which are highly effective and have far fewer side effects than their pharmaceutical counterparts. One of these is treatment with red and near infrared light (also called red light therapy or photobiomodulation), which uses light waves at specific frequencies to decrease inflammation at a cellular level. Red Light Therapy The term “red light therapy” usually describes the use of both red and near infrared light, although only the red light produced by the device is visible to the naked eye. Infrared light can still be perceived by the body as heat when it contacts skin. Red and near infrared light therapy is the application of artificially generated light in the red and near infrared spectral bands. Red and near infrared light are naturally produced by the sun, which gives off solar radiation. The term radiation describes energy that is transmitted in the form of waves or particles. The spectrum of light in our environment consists of both light we can see (visible light) and light that our eyes can’t perceive (invisible light). This is called the electromagnetic spectrum. The visible light spectrum is quite narrow, consisting of wavelengths that range from 400 to 700nm and span from violet to red in color. Red light is part of this visible light spectrum, while near infrared light is not. While early research on light therapy used primarily lasers, more recent research has found that LED’s can also be used, which also have the advantage of applying light to a larger area of the body as well as an improved safety profile. The use of LED in red/near infrared light therapy devices has also greatly reduced the cost of treatment, making it something that can be done in the comfort of one’s own home. Inflammation The inflammatory process is mediated by the immune system, specifically the innate (or non-specific) component. Inflammation protects the body from injury and infection. There are many goals of the inflammatory response, including reducing the extent of injury, limiting the spread of infection, and restoring the body back into balance. While we mostly think of inflammation as being harmful, it’s actually a natural and essential physiological function. Inflammation becomes harmful when it is uncontrolled, lasts for a long time, or just generally occurs when it shouldn’t. There are three types of inflammation, which are mainly defined by their length. Acute inflammation is short term, lasting days. This is what happens when you sprain your ankle, and it swells up, becomes warm, and may show color changes. That response is designed to limit movement, which prevents further injury and allows the damaged tissue to heal. Sub-acute inflammation lasts from two to six weeks, and often follows acute inflammation as healing progresses. The response here is similar, but less intense, than acute inflammation. Chronic inflammation lasts for months or even years, and at this point, inflammation has ceased to be a normal (and healthy) response to a stimulus and has become pathological. Chronic inflammation is the type that is associated with most diseases. It is also associated with oxidative stress. Chronic inflammation is not associated with visible signs of inflammation (such as redness, heat, and swelling), so people often aren’t even aware it is happening. This contrasts with acute inflammation, which is usually visible and occurs because of trauma or infection. Red Light Therapy for Inflammation As described by Dr. Michael Hamblin, former Associate Professor at Harvard Medical School, “one of the most reproducible effects of is an overall reduction of inflammation”. Studies have found that light therapy affects levels of many molecules involved in inflammation, including reactive oxygen species, reactive nitrogen species, and prostaglandins. Light therapy has even been found to reduce inflammation in the brain, known as neuroinflammation. Red light therapy has been shown to have anti-inflammatory effects in the following conditions: Brain Disorders – Neuroinflammation is one of the foundational pathologies underlying a wide range of brain disorders. Light therapy has been found to decrease inflammation in Alzheimer’s Disease, as well as to improve cognitive function. Several clinical trials have been published which have shown positive results. Most studies have exclusively used near infrared light, which has been found to penetrate more deeply into the brain. Light therapy has also been found to decrease inflammation and improve recovery after a stroke. When used to treat brain disorders, light therapy is usually applied to the head area, using devices such as hats and helmets. Traumatic Brain Injury - Traumatic brain injuries (TBI) occur when there is a violent blow to the head. Approximately 17% of people with repeated TBI progress to chronic traumatic encephalitis (CTE), a brain disorder caused by repeated head injuries. Concussions are another common type of TBI. TBI’s result in acute neuroinflammation, which can become a chronic problem if not treated properly. Research using light therapy (both red and near infrared) for TBI has looked at both immediate and chronic effects in animal and human models. Animal studies have shown a reduction in the size of the brain lesion when light therapy was applied to the head immediately following trauma, which correlated with the severity of neurological symptoms, which may be due (in part) to decreased inflammation. Depression – Neuroinflammation is similarly found in people suffering from depression, and it is thought to be a key factor and therapeutic target in depressive disorders. Several clinical trials of light therapy in depression have been conducted, all of which used near infrared light applied directly to the head. A 2022 systematic review concluded that light therapy “can be classified as strongly recommended for moderate grade of major depressive disorder”. Similarly, a 2023 meta-analysis concluded that there is a “promising role of in the treatment of depressive symptoms”. Gut Disorders – Inflammatory gut diseases like colitis and inflammatory bowel diseases may benefit from red light therapy. Research has found that application of red light to the abdomen of rats with experimentally induced colitis (a form of inflammatory bowel disease) improved many markers of gut health, including reducing inflammation. There is interest in studying the use of light therapy to improve gut health in human subjects as well, with research currently ongoing to see if it helps patients with inflammatory bowel disease. When treating gut disorders, light therapy is usually applied directly to the abdomen. Pain - Pain creates a huge burden of disability, both personal and economic. There is evidence that red light therapy decreases many types of pain, including knee, neck, low-back, temporomandibular joint, and post-surgical pain. Red light therapy can also reduce pain associated with arthritis and fibromyalgia. One of the primary mechanisms of pain reduction by light therapy is by decreasing inflammation. Red light therapy also reduces pain by decreasing oxidative stress, reducing the sensitivity of neurons, and decreasing the transmission of pain related nerve impulses. Arthritis – In addition to reducing arthritis pain by decreasing inflammation, the anti-inflammatory effects of red light therapy on arthritis also yields other benefits. Inflammation in arthritis is responsible for much of the observed pathology, including cartilage breakdown. Treatment with red light therapy may have a range of positive effects, such as preserving joint function, avoiding joint deformities, and reducing drug side effects and toxicities. Delayed Onset Muscle Soreness – Delayed onset muscle soreness (DOMS) is pain that occurs in the muscles between 12 and 24 hours after a workout. DOMS is caused by tiny muscle tears that results in inflammation, which causes pain. Treatment with red light therapy to muscles after a strength training session has been shown to decrease markers of inflammation, as well as to improve other outcomes like decreased fatigue and increased protein synthesis. Injury – In addition to its anti-inflammatory effects on muscle tissue, including speeding recovery from post-exercise damage, red light therapy also reduces inflammation and speeds wound healing, such as from burn injuries. Red light therapy can also reduce inflammation and speed healing from injuries to bone, including fractures and more complex bone injuries that require the use ceramic materials. Tendon injuries also benefit from red light therapy. Skin Disorders – Many skin disorders are characterized by inflammation, including acne, psoriasis and eczema. Light therapies treat acne through anti-inflammatory and antimicrobial effects, and by decreasing the production of oil. Inflammatory acne is more responsive to light therapy than non-inflammatory acne, and studies have even found it to be superior to some medications. Red and near infrared light is also recommended in the treatment of psoriasis in part because of its anti-inflammatory effects. And in eczema, an inflammatory skin disease, treatment with near infrared light therapy has been found to decrease skin itching and lesions. Alopecia Areata – Alopecia Areata (AA) is an autoimmune disease that causes the body to attack its own hair follicles. This causes the hair to fall out, resulting in patches of baldness. AA can affect hair on any part of the body but is most common on the head. It is characterized by inflammation around hair follicles during the growth phase. The anti-inflammatory effects of light therapy may decrease this inflammation. In fact, treatment with red and near infrared light has been found to increase hair growth in bald patches. How To Use Red Light Therapy To Reduce Inflammation There is no single right way to use red light therapy to reduce inflammation. It all depends on what condition you are trying to treat and what your personal preferences are as far as treatment approach. The following are a few simple questions that can be used to guide you towards selecting the device that is most suitable for your needs: 1. What are your specific health concerns? Red light is usually applied to the affected body part, either directly in contact with the skin or at a distance of around 4 to 12 inches away. Some devices are location specific, such as knee wraps, head wraps or helmets, shoulder and neck wraps, or elbow and wrist red light wraps. Other devices are non-specific, such as square or rectangular light wraps, or red light panels. If you are dealing with a single, region-specific concern – such as knee arthritis or Alzheimer’s Disease - you may prefer to get a regionally targeted red light therapy device. However, if you are dealing with inflammation in more than one area of the body and want a device that can be used in multiple locations, a non-specific wrap may be preferable. Red light panels can also be used to address multiple body parts, although they may be difficult to position properly for some locations, such as the feet and ankles. 2. What are your preferred treatment conditions? Treatments using red light panels are most often done in a seated position, with the panel oriented towards the face, neck, torso, or other affected body part. They can also be done in a standing position, although this is not as relaxing. Lying down is possible if the treatment location allows it. Red light panels are wired and require the user to stay in the same position throughout the duration of the treatment. In contrast, treatments using red light wraps can be done in any position, including standing, sitting, and lying down. They can even be worn while moving around. Some red light wraps are wired, while others are wireless, with wireless models providing more flexibility. 3. What device specs should you look for? At home red light therapy devices almost always use LED’s as the light source. However, they do vary in other parameters, such as light wavelength(s) and intensity. When it comes to choosing the optimal wavelengths, you should look for light in the red and/or near infrared spectrums - but avoid the range of 700-780nm which has been found to be ineffective. Multi-wavelength devices including both red and near infrared light may be the most versatile. In terms of intensity, it has been found that it is ideal to mimic the intensity of the sun, which is around 24 mW/cm2 at the skin. This is described as the “sweet spot” between higher intensities, which can have harmful effects, and lower intensities, which will have no effect at all. Many devices on the market are at a much higher intensity than the sun, so choose a sun-mimicking product and don’t overdo it when it comes to treatment frequency and duration. Conclusion Red light therapy (with red and near infrared light) may be used to reduce inflammation in a wide range of diseases, both acute and chronic. There are very few contraindications to red light therapy, and it can be safely used at home as part of a regular wellness regime. Choose a device that suits your needs and preferred treatment conditions, and which delivers both red and near infrared light at an appropriate intensity. Combine red light therapy with an anti-inflammatory diet and supplements, regular exercise, stress management, and good sleep hygiene for best results.

Red Light Therapy for Chronic Inflammation
Chronic inflammation has recently been proposed as being the common underlying cause of the “four horsemen of the medical apocalypse”, which are heart disease, diabetes, cancer, and Alzheimer’s Disease. Inflammation has also been suggested as a biological cause of depression. And it is a hallmark of other diseases such as arthritis, ulcerative colitis, and inflammatory bowel disease. Not surprisingly, some of the most widely used drugs are anti-inflammatory medications, both prescription and over the counter. By 2030, the global market for non-steroidal anti-inflammatory drugs (NSAIDS) is projected to reach over 31 billion USD. However, many of these drugs have serious side effects, such as hypersensitivity reactions and ulcers. Red and near infrared light have anti-inflammatory effects, and unlike medications, do not cause harm. Studies have found that red and near infrared light affect levels of many molecules involved in inflammation, such as prostaglandins. The ability of red and near infrared light to reduce inflammation suggests that it could have therapeutic potential in many chronic diseases that involve inflammation, including arthritis, Alzheimer’s Disease, and depression. Red and near infrared light therapy devices come in panels and wearable forms such as wraps. Wearable wraps provide more flexibility in terms of application while panels are better for general irradiation of larger surfaces. Fringe makes a 12x12 inch red light panel as well as a variety of light therapy wraps that are specific to certain areas (such as the head, knee, shoulder, or elbow) as well as small and large wraps that can be used on most parts of the body. Designed to mimic the intensity of the sun using LED light chips, these products are a great addition to an anti-inflammatory wellness plan.

Red Light for Arthritis
Arthritis refers to a group of diseases that are characterized by inflammation. Inflammation (also known as swelling) can cause both pain and stiffness. The two main types of arthritis are osteoarthritis – where joint damage causes inflammation – and inflammatory arthritis – where inflammation itself causes joint damage. Most inflammatory arthritis conditions are autoimmune in nature. Arthritis can affect any joint in the body, but is most common in the hips, knees, and spine. For years, anti-inflammatory and pain-relieving pharmaceuticals were used as first-line therapies for arthritis, with natural therapies viewed as being less effective. However, the widespread use of opioids resulted in an epidemic of addiction that necessitated the search for new ways to deal with pain. These medications also have side effects such as GI bleeding. Given these risks, many people are turning to non-invasive therapies to fight arthritis, some of which are highly effective and have far fewer side effects than their pharmaceutical counterparts. One of these is treatment with red and near infrared light (also called red light therapy or photobiomodulation), which uses light waves at specific frequencies to decrease inflammation at a cellular level. As described by Dr. Michael Hamblin, former Associate Professor at Harvard Medical School, “one of the most reproducible effects of is an overall reduction of inflammation”. Studies have found that light therapy affects levels of many molecules involved in inflammation, including reactive oxygen species, reactive nitrogen species, and prostaglandins. This makes red light therapy well suited to treat both osteo- and inflammatory arthritis. In addition to reducing arthritis pain by decreasing inflammation, the anti-inflammatory effects of red light therapy on arthritis also yields other benefits. Inflammation in arthritis is responsible for much of the observed pathology, including cartilage breakdown. Treatment with red light therapy may have a range of positive effects, such as preserving joint function, avoiding joint deformities, and reducing drug side effects and toxicities. Fringe makes many red light products that can be used to treat arthritis, including joint wraps, rectangular wraps, and red light panels. If you are dealing with a single, region-specific concern you may prefer to get a regionally targeted red light therapy device, like the Fringe Knee/Foot/Ankle or Elbow/Wrist Wrap. However, if you are dealing with arthritis in more than one area of the body and want a device that can be used in multiple locations, a non-specific wrap (like the Fringe Red Light Therapy Wrap or Extra Long Wrap) may be preferable. The Fringe Red Light Panel can also be used to address multiple body parts, although it may be difficult to position properly for some locations, such as the feet and ankles. There are very few contraindications to red light therapy, and it can be safely used at home for the treatment of arthritis. Choose a device that suits your needs and preferred treatment conditions, and which delivers both red and near infrared light at an appropriate intensity.
