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. Combine red light therapy with an anti-inflammatory diet and supplements, regular exercise, stress management, and good sleep hygiene for best results.

Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are two of the most common neurodevelopmental conditions in children and adolescents, and both frequently persist into adulthood. In the US, ADHD is estimated to affect approximately 7 million children, while ASD affects roughly 1 in 31 children, according to recent surveillance data.
Although autism and ADHD are distinct diagnoses, they often overlap clinically. Many individuals with ASD also meet criteria for ADHD, and both conditions can involve challenges with attention, emotional regulation, sleep, and executive function. In fact, 50-70% of people with ASD also meet the criteria for ADHD.
Beyond behavioral symptoms, research over the past two decades has identified recurring biological themes in both conditions. These findings do not suggest that ASD or ADHD are caused by a single mechanism. Both are multi-factorial and are influenced by complex genetic and environmental factors. However, patterns involving cellular energy metabolism, inflammation, gut–brain signaling, and circadian regulation have been repeatedly observed. These shared biological themes have opened the door to new supportive, non-pharmacologic strategies that target cellular function and regulatory balance.
One area of emerging interest is photobiomodulation, commonly referred to as Red Light Therapy (RLT). RLT uses red and/or near-infrared light to influence biology and has been studied for decades in the context of wound healing, musculoskeletal health, and brain injury. More recently, early-stage research has begun exploring its potential role in supporting brain function in conditions such as ADHD and ASD.
In this article, we will review:
The biological overlap between ASD and ADHD
How red and near-infrared light influences cellular function
What current research shows (and does not show) in these conditions
Practical considerations for safe and thoughtful use
As always, our goal is not to position red light therapy as a cure or replacement for established therapies. Instead, we aim to present the science clearly, so families and clinicians can make informed decisions about whether it may serve as a complementary support strategy.
What Is Red Light Therapy, and How Does It Work?
Red light therapy refers to the use of specific wavelengths of red and near infrared light to influence biological function. Unlike ultraviolet light, red and near infrared wavelengths are non-ionizing and do not damage DNA at therapeutic intensities. Instead, they interact with cells through light sensitive molecules called chromophores.
Most RLT devices use wavelengths in the red range, commonly around 630 to 660 nm, and the near infrared range, commonly around 800 to 850 nm, although some use longer wavelengths (over 1000nm) for broader effects. Red light tends to interact more strongly in superficial tissues, while near infrared light penetrates more deeply into soft tissue. For this reason, many devices combine both wavelengths. RLT devices that target brain health sometimes use only near infrared light, due to its deeper penetration, while others use both red and near-infrared for broader effects.
The best supported biological mechanism involves the mitochondria, the energy producing structures inside cells. Red and near infrared light have been shown to influence mitochondrial function, including pathways related to cellular energy production and cellular redox signaling. When mitochondrial function is supported, cells may regulate inflammation, oxidative stress, and metabolic activity more effectively.
In the brain, RLT has been studied for its effects on energy metabolism, inflammation, blood flow, and neural signaling. These mechanisms are part of why researchers have begun exploring red and near infrared light in brain health applications, including emerging work in ADHD and autism.
What is the Shared Biology of ADHD and Autism?
Although ADHD and ASD are distinct clinical diagnoses, research increasingly shows that they share overlapping biological patterns. These shared themes do not define every individual with either condition, and neither condition can be reduced to a single mechanism. However, certain pathways appear repeatedly in the scientific studies. Understanding these patterns helps explain why interventions that support cellular energy, inflammation regulation, gut function, and sleep may be relevant in both conditions.
1. Mitochondrial Dysfunction and Impaired Brain Energy Metabolism
Mitochondria are responsible for producing cellular energy in the form of ATP. The brain is one of the most energy-demanding organs in the body, and even subtle shifts in energy metabolism can influence attention, emotional regulation, and executive function.
In ADHD, studies have reported alterations in mitochondrial activity, increased oxidative stress, and changes in brain energy metabolism. In ASD, mitochondrial dysfunction has been observed in a significant subset of individuals, including abnormalities in electron transport chain activity, altered redox balance, and increased markers of oxidative stress.
Not every person with ADHD or ASD has measurable mitochondrial dysfunction. However, cellular energy regulation appears to be a recurring theme in both conditions.
2. Increased Oxidative Stress and Neuroinflammation
Oxidative stress refers to an imbalance between reactive oxygen species and antioxidant defenses. When persistent, it can influence cellular signaling, immune activity, and neural function.
Elevated oxidative stress markers have been reported in both ADHD and ASD. In ASD in particular, neuroinflammation has been studied extensively. Post-mortem and imaging studies have identified activated microglia and altered inflammatory signaling in subsets of individuals with ASD. Neuroinflammation has also been observed in ADHD.
Neuroinflammation does not imply infection, and it does not apply uniformly to all individuals with ASD or ADHD. Rather, it reflects altered immune signaling within the brain that may interact with mitochondrial function and oxidative stress pathways.
3. Altered Gut–Brain Axis & Microbiome
The gut and brain communicate bidirectionally through neural, immune, and metabolic signaling pathways. This is often referred to as the gut–brain axis.
In ADHD, research has identified differences in gut microbiome composition and diversity compared to neurotypical controls. In ASD, gastrointestinal symptoms are common, and multiple studies report microbiome differences, altered short-chain fatty acid profiles, and immune signaling shifts linked to gut health.
The gut–brain axis is complex and not fully understood. However, microbiome composition can influence inflammation, neurotransmitter production, and metabolic signaling, all of which are relevant to attention and behavior.
4. Circadian Rhythm and Sleep Dysregulation
Sleep disturbance is common in both ADHD and ASD. In ADHD, delayed sleep phase, difficulty with sleep onset, and evening alertness patterns are frequently reported. In ASD, sleep disturbance rates are high, with research showing differences in melatonin regulation and circadian rhythm signaling in some individuals.
Circadian rhythm regulation is closely connected to mitochondrial function and inflammatory signaling. Disrupted sleep can amplify cognitive, emotional, and behavioral challenges in both conditions.
How Does Red Light Therapy Intersect with These Pathways?
This interconnected framework helps explain why researchers are exploring interventions that support cellular energy metabolism and regulatory balance across systems, rather than targeting only one symptom at a time. RLT has attracted interest in this context because of its documented effects on all four of the biological patterns that are commonly observed in both ADHD and ASD.
1. Mitochondrial and Cellular Energy Support
The most widely studied mechanism of red and near-infrared light involves the mitochondria, and through the mitochondria, light also affects metabolism. In addition to regulating reactive oxygen species production, mitochondria also make the energy currency of the cell, called ATP. Specifically, red and near-infrared light stimulates cytochrome c oxidase, a mitochondrial enzyme that produces ATP. This increases ATP synthesis which provides more energy to brain cells. This appears to support more efficient cellular energy regulation under certain conditions.
2. Oxidative Stress Modulation
Light is absorbed in cells by molecules called chromophores, many of which are found inside the mitochondria. Mitochondria are involved in regulating the production the reactive oxygen species that cause oxidative stress when present in high amounts. Light therapy has been shown to modulate oxidative stress and reactive oxygen species production.
3. Inflammation Reduction
Red and NIRL have anti-inflammatory effects, and studies have found that light therapy affects levels of many molecules involved in inflammation, including reactive oxygen species, reactive nitrogen species, and prostaglandins.
Red and near-infrared light therapy have specifically shown to reduce neuroinflammation. Some of these anti-inflammatory effects are linked to improved mitochondrial redox signaling. Others appear to involve immune cell modulation and nitric oxide signaling pathways.
4. Gut–Brain Axis & Microbiome Support
Red and near-infrared light can be applied not only to the head but also to the abdomen. The intestinal lining is metabolically active and rich in mitochondria, and the gut microbiome interacts closely with immune and metabolic signaling systems. Animal and human research suggests that RLT may influence microbiome composition and gut inflammatory pathways. This axis represents an additional pathway through which light exposure to the body could exert indirect effects on the brain.
5. Circadian Rhythm and Sleep Regulation
Red and near-infrared light interact with cellular energy systems and nitric oxide pathways, which may help support biological processes related to sleep quality. Research suggests that light exposure may improve sleep quality, especially when light is applied to the head. Importantly, unlike blue light exposure at night, red and near-infrared wavelengths do not suppress melatonin and are generally considered circadian-friendly. Improved sleep alone can meaningfully affect attention, mood regulation, and executive function which is highly relevant for people with ADHD and ASD.
What Current Research Shows, and What It Does Not
Research on red light therapy in autism and ADHD is still early, but a small number of human and animal studies have begun exploring its effects. Below is a brief overview of the most relevant studies to date.
Several small clinical and preclinical studies have examined transcranial red and near-infrared light in autism:
Diaz et al., 2026 - In this prospective open label case series, eight weeks of near-infrared RLT applied to the head of ASD subjects ages 6-38 resulted in improvements in cognition, emotional regulation, focus, and sleep quality.
Fradkin et al., 2024 – In this randomized controlled trial, eight weeks of near-infrared RLT applied to the head in children 2-6 years resulted in statistically significant reductions in autism severity scores compared to sham treatment, with no moderate or severe adverse effects reported.
Pallanti et al., 2022 – Six months of home-based near-infrared RLT applied to the head by 21 subjects with an average age of 9.1 years was associated with improvements in autism severity, rigidity, sleep quality, attention, and reduced parental stress.
Ceranoglu et al., 2022 – Adults with high-functioning autism showed improvements in social responsiveness and executive function after eight weeks of treatment with near-infrared light applied to the head.
Kim et al., 2022 – In a mouse model of autism, red/near-infrared light reduced neuroinflammation and improved social and cognitive behaviors.
Research in ADHD is more limited, but studies have explored both human and animal models:
Lai et al., 2025 – Adults with ADHD who received near-infrared light to the head for four weeks showed improvements in working memory and sustained attention performance, with mild and transient side effects.
Huang et al., 2025 – In a rat model of ADHD, red/near-infrared light reduced hyperactivity and impulsivity behaviors and decreased markers of neuroinflammation in the prefrontal cortex.
Taken together, these studies indicate that RLT with near-infrared light can influence biological systems relevant to both autism and ADHD, including mitochondrial function, inflammatory signaling, and neural connectivity, especially when applied to the head. Early human trials suggest potential improvements in attention, executive function, and autism severity scores, and animal studies consistently show reductions in neuroinflammation and behavioral improvements. Importantly, safety signals across studies have been reassuring, with few serious adverse effects reported in either pediatric or adult populations.
At the same time, this field is still in its early stages. Most studies are small, and only one ASD study to date has used a randomized sham-controlled design. There are no large, multi-center clinical trials in either ADHD or autism, and long-term outcomes have not been well studied. Treatment protocols vary widely, making it difficult to compare results across studies.
Red light therapy should not be viewed as a cure or a replacement for established therapies. Rather, current research suggests it may serve as a complementary approach that supports underlying biological systems in some individuals.
Practical Ways to Use Red Light Therapy for ADHD and Autism
If families or clinicians choose to explore RLT as a supportive approach in ADHD or ASD, it can be helpful to think about three areas discussed earlier in this article: brain function, gut–brain signaling, and circadian rhythm regulation.
Common approaches include:
We recommend a frequency of 3-5 times per week, although it is also safe to use RLT daily. Some people choose to alternate locations daily, applying light to the head one day and to the gut the following day. It is also possible to apply light to both the head and gut in the same day. Because some individuals with ASD have sensory sensitivities, it may be helpful to start gradually and ensure the device feels comfortable.
Red light therapy should not replace established medical or behavioral care. However, emerging research suggests it may support biological systems relevant to ADHD and ASD, including cellular energy metabolism, inflammation, and circadian regulation.
Conclusion
Both ASD and ADHD involve complex interactions between brain biology, metabolism, sleep, and the gut–brain axis. Red and near-infrared light therapy is an emerging area of research that may help support some of these underlying systems.
Although the science is still developing, early findings are encouraging. For families and clinicians interested in complementary approaches, RLT may offer a simple, non-invasive way to support overall neurological health alongside established care.
Light therapy is increasingly used as a supportive tool for everyday health challenges that come up in family life. Using red, near infrared, and blue light, light therapy works at a cellular level to support processes like energy production, inflammation regulation, circulation, and nervous system balance. Because these processes are shared across all ages, light therapy can be adapted to a wide range of common needs, from skin irritation and minor injuries to immune support and digestive comfort.
The Fringe Tiny Wrap was designed with this flexibility in mind. Its compact size and multiple light options make it easy to target specific areas of the body, allowing families to incorporate light therapy into daily routines in a simple, focused way.
Below are some of the most common ways families incorporate red, near infrared, and blue light using the Fringe Tiny Wrap.
1. Aches, Pains, Bumps & Bruises
Red and near-infrared light are commonly used to support circulation, cellular energy production, and inflammatory balance following minor injuries or physical strain. This can be helpful for sore muscles, tender spots, or bruises that linger after everyday activity. The Tiny Wrap’s small size makes it easy to place directly over the affected area, supporting recovery without restricting movement.
2. Skin Rashes & Inflammation
Skin irritation and inflammation can appear anywhere on the body and often involve a mix of barrier disruption, inflammation, and microbial imbalance. Red and near-infrared light may support tissue repair and calm inflammatory responses, while blue light is known for its antimicrobial effects. The Tiny Wrap allows for targeted skin support in areas where larger devices aren’t practical.
3. Allergies & Seasonal Sensitivities
Allergies are best understood as an over-reactive immune response rather than a weak one. Light therapy is sometimes used to support immune balance and tissue response during seasonal or environmental challenges. When symptoms are localized (such as sinus, skin, or upper-chest discomfort) the Tiny Wrap can be used to deliver focused light support as part of a broader wellness routine.
4. Asthma-Related Inflammation
While light therapy is not a treatment for asthma, red and near-infrared light are sometimes discussed in the context of supporting inflammatory balance and relaxation in surrounding tissues. The Tiny Wrap’s compact design allows for gentle placement on areas like the upper chest or back, always alongside appropriate medical care and guidance.
5. Colds & Flus
During periods of illness, the body’s energy and recovery demands increase. Red and near-infrared light are often used to support circulation, inflammation regulation, and cellular energy during rest and recovery. The Tiny Wrap makes it easy to apply light to areas such as the chest, back, or neck without adding strain during times when rest is a priority.
6. Growing Pains
Periods of rapid growth are often accompanied by leg discomfort, muscle tightness, or nighttime aches. Light therapy is commonly used to support muscle relaxation, circulation, and comfort when applied locally to the legs or joints. The Tiny Wrap is especially well suited for this type of targeted, localized support.
7. Emotional Regulation & Stress
The nervous system plays a central role in how the body responds to stress, sensory input, and emotional load. Light therapy is sometimes incorporated into calming routines to support nervous system balance and regulation. Because the Tiny Wrap is small and unobtrusive, it can be used gently and briefly as part of wind-down or regulation-focused routines.
8. Gut Health & Digestive Comfort
Red and near infrared light applied externally to the abdomen are often discussed in the context of supporting digestive comfort, inflammatory balance, and gut–brain communication. The Tiny Wrap works well for focused abdominal placement, making it a practical option during periods of digestive stress or disruption.
9. Immune Support
Immune function depends heavily on cellular energy availability and efficient inflammatory signaling. Light therapy is often used during times of increased immune demand to support these underlying processes. The Tiny Wrap’s portability and ease of placement make it convenient to incorporate into daily routines during cold season or periods of stress.
10. Targeted Skin Support Anywhere on the Body
With blue light for surface-level skin concerns and red and near-infrared light for deeper tissue support, the Tiny Wrap is especially useful for localized skin needs beyond the face. Its precision placement allows families to support specific areas of concern wherever they appear, without committing to larger devices.
Say Hello to the Tiny Wrap
Conclusion
At Fringe, we view light therapy as a foundational, at-home tool that supports the body on a cellular level. The Fringe Tiny Wrap reflects this philosophy by offering red, near infrared, and blue light in a small, adaptable format designed for precision placement. By making light therapy easy to use, easy to place, and easy to integrate into daily routines, the Tiny Wrap helps families support comfort, resilience, and everyday health in a simple, consistent way.
Fringe Kids Mission
We’re excited to introduce the Fringe Kids Mighty Multivitamin, a food-based vitamin and mineral supplement designed to support growing bodies.
This formula was created to fill common nutritional gaps in children’s diets using primarily food derived ingredients rather than synthetic isolates. It provides foundational vitamins and minerals that support energy, learning, immune function, and overall development, without added sugar, artificial or “natural” flavors, dyes, or unnecessary additives.
At Fringe, we believe children deserve supplements that are as thoughtful and intentional as the food we try to put on their plates. The Kids Mighty Multivitamin was designed with that philosophy in mind.
Nutrient Depletion and Nutrient Gaps in Modern Childhood
When we look at the context for children’s nutrition today, it helps to separate two related but distinct issues. One is the nutrient content of what children eat and drink. The other is whether what they consume provides enough of the vitamins and minerals their bodies need for growth, learning, immunity, and everyday function.
Many aspects of our food supply have shifted over the past several decades in ways that can affect both vitamin and mineral content. Studies of nutrient density in fruits, vegetables, and staple crops have documented declines in both minerals and vitamins compared with historical baselines, reflecting changes in agricultural practices, plant breeding, soil quality, and global food systems. These analyses have found measurable drops in nutrients such as calcium, magnesium, iron, vitamin A, and vitamin C in a range of produce over time, suggesting that even when children eat foods that appear wholesome, the absolute nutrient content per serving may be lower than it once was. Magnesium has been especially affected, with losses of up to 80-90% in some foods over the last century.
In addition to agricultural influences, naturally occurring minerals in water such as calcium, magnesium, sodium, chloride, and potassium have traditionally contributed to daily intake for many individuals. Depending on local water composition, these minerals can account for meaningful portions of recommended intake values, particularly for calcium and magnesium. However, modern filtration practices remove these minerals from water in the process of ridding them of contaminants, which can reduce overall nutrient intake. Collectively, these patterns in food and water help explain why certain micronutrients are consistently identified as shortfall nutrients in U.S. dietary surveys.
National data from the National Health and Nutrition Examination Survey (NHANES) show that many U.S. children do not meet recommended intakes for multiple vitamins and minerals when intake is assessed from foods and beverages alone. In toddlers and young children, large proportions fall below the Estimated Average Requirement (EAR) for vitamin D and vitamin E, while most do not reach Adequate Intake (AI) levels for potassium and choline. As children move into the school-age years, nutrient gaps widen, with continued inadequacy in vitamin D, vitamin E, calcium, choline, and potassium. By adolescence, NHANES data show widespread shortfalls across a broad range of nutrients, including vitamin D, vitamin E, calcium, magnesium, folate, iron, and potassium, with particularly high rates of inadequacy among adolescent females. These patterns occur even when overall calorie intake is sufficient, indicating that nutrient gaps reflect dietary quality and food patterns rather than simple undereating.
These gaps are not simply a “picky eater” issue. They reflect modern dietary patterns that can provide adequate calories while still falling short on micronutrients. One major factor is the high proportion of daily calories coming from ultra processed foods among U.S. youth. Ultra processed food intake increased among U.S. youths from 1999 to 2018, with recent CDC NHANES-based surveillance data reporting that youth ages 1 to 18 obtain about 62 percent of calories from ultra processed foods. When a large share of the diet is coming from foods designed for convenience, shelf stability, and hyper palatability, there is less room for consistent intake of nutrient dense staples like vegetables, legumes, seafood, and mineral rich whole foods.
The take-home point is that nutrient gaps in U.S. children are measurable, consistent, and widespread, affecting both vitamins and minerals. These gaps matter because many micronutrients support foundational biological processes, from energy metabolism to immune signaling to neurologic development. When intake falls short of recommended levels year after year, it contributes to what nutrition scientists describe as chronic insufficient intake, or “micronutrient gaps,” rather than acute clinical deficiency. Addressing these gaps requires thoughtful support for nutrients that are hard to obtain consistently from modern diets alone. This is the context in which a carefully designed children’s multivitamin can serve as a nutritional backstop for growing bodies.
Why These Nutrients Matter During Childhood
Identifying nutrient gaps is only part of the picture. It is also important to understand why adequate intake matters during childhood, when growth and development place higher and more dynamic demands on the body. Vitamins and minerals support fundamental biological processes, and when intake consistently falls below age-appropriate needs, those processes can be affected even in the absence of overt deficiency disease.
1) Growth and physical developmentNormal growth during childhood depends on the coordinated activity of multiple micronutrients that support cell division, tissue development, and skeletal maturation. Zinc plays a role in growth and bone formation, calcium and vitamin D are central to bone mineralization and skeletal integrity, magnesium supports bone structure and energy metabolism, and iron contributes to oxygen delivery and physical capacity during growth. Research has shown that inadequate intake or status of these nutrients can be associated with impaired growth patterns, reduced bone mineral density, or suboptimal physical development, particularly during periods of rapid growth. While severe deficiency states are uncommon in high-income countries, habitual intakes that fall below recommended levels may still limit optimal support for these foundational processes over time.
2) Brain development, learning, and cognitionBrain development during childhood relies on a steady supply of micronutrients that support neuronal growth, myelination, neurotransmitter synthesis, and energy metabolism in the nervous system. Iron is required for oxygen delivery and normal neurodevelopment, and inadequate iron status in childhood has been associated with alterations in cognitive development and attention. Iodine is essential for thyroid hormone production, which plays a central role in brain development and cognitive function, particularly during early life. Choline contributes to cell membrane structure and neurotransmitter synthesis and is involved in pathways related to memory and learning, yet intake is consistently low in children. Several B vitamins, including folate, vitamin B6, and vitamin B12, support one-carbon metabolism and neurotransmitter production, while magnesium participates in neuronal signaling and energy metabolism. When habitual intake of these nutrients falls below recommended levels, it may limit optimal support for the developing brain, especially during periods of rapid learning and cognitive growth.
3) Immune function and energy metabolismThe immune system and the body’s ability to produce and regulate energy are closely tied to micronutrient status during childhood. Vitamin A supports the integrity of epithelial barriers and immune cell differentiation, while vitamin D plays a regulatory role in both innate and adaptive immune responses. Vitamin C and zinc contribute to immune cell function and antioxidant defense, and inadequate intakes have been associated with altered immune responsiveness. At the same time, nutrients such as magnesium, iron, and B vitamins are involved in mitochondrial function and enzymatic reactions that govern energy production and cellular metabolism. When intake of these nutrients is consistently low, children may have less metabolic flexibility to meet the demands of growth, physical activity, and immune challenges, even if overt illness or deficiency is not present.
Taken together, this research highlights that vitamins and minerals support a wide range of foundational processes during childhood, from physical growth to brain development to immune and energy regulation. When intake consistently falls short of age-appropriate needs, these systems may be supported less efficiently over time, even in the absence of overt deficiency. This is the context in which maintaining adequate, consistent micronutrient intake becomes relevant to everyday childhood health.
Why We Consider a Multivitamin “Essential” for Kids (Even for Healthy Eaters)
We consider a children’s multivitamin essential because meeting nutritional needs consistently over time is challenging, even in families that prioritize healthy food. As we’ve just seen, nutrition needs are often unmet due to nutrient gaps, water and mineral depletion of vitamins and minerals, and high consumption of ultra processed food. In addition, childhood is a period of rapid growth and development, and the demand for vitamins and minerals shifts alongside physical growth, brain development, immune maturation, and learning. At the same time, food intake is rarely steady, varying with changes in appetite, preferences, and habits.
Even with a well-planned diet, children do not eat the same foods in the same amounts every day, and nutritional adequacy is determined by patterns over weeks and months rather than by individual meals. Some nutrients need to be consumed regularly to maintain adequate levels, and repeated shortfalls, even small ones, can accumulate during periods of growth. This reality is not a reflection of poor parenting or poor dietary choices, but a natural consequence of childhood and the modern food environment.
We believe that a daily kid’s multivitamin with minerals is “essential” because it provides a steady nutritional baseline when intake is uneven, inadequate, or unpredictable. While this support can be provided by synthetically sourced nutrients, food-based vitamins and minerals are delivered in amounts and combinations that more closely resemble how nutrients occur in the diet, which allows them to support physiology in a way that is gentler and more consistent with nature. In this context, a food-based multivitamin is better suited to act as an everyday nutritional backstop, working alongside real food rather than attempting to replace it or override normal dietary patterns.
Fringe Kids Mighty Multivitamin: What’s In It?
When we formulate supplements for children, we start by asking a simple question: what does the body actually need on a daily basis, and how can we provide that support in the most appropriate way? The Kids Mighty Multivitamin was built using a “nature first” philosophy with that question in mind, using a combination of whole-food nutrients, targeted additions, and carefully chosen supporting ingredients to create a formula that is both effective and gentle.
Meet the Mighty Good Multivitamin!
1. The Foundation: A Whole-Food Nutrient Blend
At the core of the Kids Mighty Multivitamin is a 21-nutrient, organically grown fruit and vegetable blend, which provides a broad spectrum of vitamins, minerals, and phytonutrients in a form that closely resembles how nutrients occur in food. This blend includes broccoli, spinach, kale, pumpkin, sweet potato, sunflower seed, cranberry, chlorella, maitake mushroom, and shiitake mushroom.
Because this multivitamin is built on a food-based foundation, some of the vitamin forms may look different from what people are used to seeing in standalone supplements. The vitamin D present in the blend is vitamin D2, and the vitamin K is vitamin K1, which reflect the forms naturally found in plant foods. Vitamin D3 and vitamin K2 can also be derived from natural, vegan sources and are often used in targeted supplements for specific goals (such as our Fringe Vitamin DK supplement). In this formula, however, the intent is different. As an everyday, food-based multivitamin, the goal is to provide gentle, consistent nutritional support using nutrient forms that align with how vitamins are typically consumed in the diet, while still supporting normal absorption and biological function.
By building our multivitamin around real foods rather than isolated synthetic vitamins, we aim to provide nutritional support that works alongside the body’s natural processes, rather than overwhelming them with high doses of single compounds.
2. What We Added, and Why
While a food-based foundation can provide a broad range of vitamins and minerals, it also reflects the realities of the modern food system. Declines in soil mineral content, loss of naturally occurring minerals from filtered water, and inconsistent intake of nutrient-dense foods mean that some nutrients are simply harder for children to obtain in adequate amounts, even with a diet built around whole foods. For that reason, relying on a fruit and vegetable blend alone is not always sufficient to meet foundational needs. Based on intake data and these practical constraints, we made the intentional decision to add three nutrients that consistently emerge as shortfall nutrients in children.
Magnesium was added because it plays a central role in energy metabolism, muscle and nerve function, and overall cellular health, and because both dietary intake and environmental availability have declined over time.
Calcium, sourced from calcified algae, was added to support bone development and growth during childhood, using a naturally derived form that fits within a food-based framework.
Choline is the only synthetic ingredient in the formula, and its inclusion was deliberate. Choline is essential for brain development, cell membrane structure, and neurotransmitter synthesis, yet intake is consistently low in children. Because choline is not present in meaningful amounts in most plant foods or food-based blends, we chose to include it as a standalone nutrient to ensure adequate support during key developmental years.
3. The Supportive Players
Beyond the primary nutrients, the Kids Mighty Multivitamin includes a small number of supportive ingredients that were chosen with equal care. Chicory root inulin provides a gentle source of prebiotic fiber to support gut health. Organic freeze-dried raspberry and strawberry fruit powders contribute natural flavor and color without added sugar or artificial ingredients. Organic rice hulls serve a functional role in the powder without introducing unnecessary additives.
For sweetness, we use thaumatin, a protein-derived sweetener sourced from the katempfe fruit. Thaumatin is intensely sweet, which allows us to use it in extremely small amounts, contributing virtually no calories and having no impact on blood sugar. Unlike many other sweeteners used in children’s supplements, thaumatin does not rely on sugar alcohols, stevia, or artificial sweeteners, making it a cleaner and better-tolerated option. Malic acid, which occurs naturally in fruits, is included to support flavor and palatability while fitting seamlessly into a food-based formulation. We’ve taste tested our Mighty Multivitamin with kids and they’ve loved it!
Every ingredient in the Kids Mighty Multivitamin serves a purpose. There are no dyes, added sugars, “natural” or artificial flavors, or unnecessary fillers. The goal is not to make a supplement that looks or tastes like candy, but one that supports children’s health thoughtfully and responsibly, using ingredients that align with how their bodies are meant to be nourished.
How to Use It
The Kids Mighty Multivitamin is designed to provide meaningful nutritional support without overwhelming the system or attempting to replace food. Across age groups, the recommended servings deliver supportive amounts of most vitamins and minerals, generally falling in at 30-70% of daily requirements. This is intentional. The goal is to leave room for nutrients to come from the diet while providing a steady baseline that helps cover common gaps when intake is uneven or unpredictable. At times when nutritional intake is clearly inadequate, the recommended daily dose can be increased by 1/3, 1/2, or – on rare occasions – even a full scoop.
For many nutrients, daily intakes in the range of moderate support rather than full replacement are both appropriate and desirable, particularly when a multivitamin is used long term. Calcium is a good example. The amount included in Kids Mighty is not intended to meet daily calcium needs on its own, but rather to mirror the type of calcium intake that typically accompanies meals. Most children obtain calcium primarily from food, and this formula is designed to complement that pattern rather than override it.
Vitamin D deserves special mention. While Kids Mighty provides a food-based source of vitamin D, many children will still require additional vitamin D supplementation depending on factors such as sun exposure, latitude, season, skin coverage, and time spent outdoors. When vitamin D is supplemented separately, vitamin K should also be included to support proper calcium handling and bone health. This is why we offer a dedicated vitamin D and K supplement for families who need targeted support beyond what a daily multivitamin can reasonably provide.
To use, simply mix the recommended serving into water, a beverage, or food of choice and stir well.
Ages 2 to 3: ⅓ scoop daily
Ages 4 to 8: ½ scoop daily
Ages 9 and up: 1 scoop daily
Kids Mighty is not intended for children under 2 years of age.
As with all Fringe supplements, this product is meant to work alongside real food, not replace it. Think of it as a quiet, consistent layer of support that fits into daily life and adapts to the realities of growing bodies, changing appetites, and modern nutrition.
Kids Mighty Multivitamin & Our Small Scoops Mission
The Kids Mighty Multivitamin was created as a reflection of our Small Scoops Mission. We believe that supporting children’s health means being thoughtful and restrained, not aggressive or excessive. Supplements should work alongside food, respect the body’s natural processes, and provide meaningful support without unnecessary ingredients or high doses.
Every aspect of our Kids Mighty Multivitamin was designed with this philosophy in mind. A food-based foundation, targeted additions where modern diets often fall short, and carefully chosen supporting ingredients, all combined in amounts that are intended to complement, not replace, real food. Just as important are the ingredients we chose to leave out, including added sugars, artificial and “natural” flavors, dyes, and unnecessary fillers.
As parents, we take seriously the responsibility of formulating for children. The Small Scoops Mission is about stewardship, transparency, and long-term thinking, and Kids Mighty is our way of putting that into practice in a form that fits naturally into daily life.
