Fringe “Essentials” Supplements
At Fringe, we believe that foundational health starts with giving your body what it needs to function every single day. That’s why we created our Essentials line: three core supplements that we think most people should take on most days.

These include:
- Vitamin D & K Mix – for bone, immune, and cardiovascular health.
- Magnesium Mix – to support over 800 enzymatic processes in the body.
- Electrolyte + Mineral Mix – to replenish the vital nutrients missing from modern water.
Each was chosen not because they’re trendy, but because they fill real gaps created by how we live today — from sun avoidance to soil depletion to water purification.
Here’s why these three have earned their place in our Essentials line.
1. The Vitamin D & K Combo: A Vital Synergy
The Widespread Problem of Vitamin D Deficiency
Despite being called the “sunshine vitamin,” most people today don’t get enough vitamin D — especially in North America, where long winters, sunscreen use, and indoor living are the norm. Over 90% of Americans don’t get enough vitamin D from their diets, making supplements essential to raise vitamin D levels when sun exposure is inadequate.
Why does this matter?
Vitamin D plays a crucial role in:
- Calcium absorption
- Bone mineralization and remodeling
- Immune function, including pathogen defense and inflammation control
- Mood regulation and brain health
But supplementing with Vitamin D alone isn’t enough. How your body uses that calcium matters too.
Vitamin K: Vitamin D’s Partner in Calcium Transport
Vitamin K (especially MK-7, the most bioavailable form of vitamin K2) acts like a traffic director for calcium, whose absorption from the intestines is regulated by vitamin D. It activates proteins that help shuttle calcium into bones and teeth (where it belongs), and away from soft tissues like arteries (where it absolutely does not belong).
Without adequate vitamin K, high vitamin D and calcium levels could contribute to arterial calcification and cardiovascular issues. That’s why we combine Vitamin D3 and K2 (MK-7) in our Fringe Vitamin D & K Mix.
In short: Vitamin D helps you absorb calcium. Vitamin K makes sure it goes to the right places.
2. Magnesium: The Mineral You're Probably Not Getting Enough Of
Magnesium is involved as a cofactor or activator in more than 800 enzymatic reactions in the body — everything from energy production and muscle function to blood sugar regulation and stress modulation.
Yet it’s one of the most commonly deficient nutrients, with over 50% of adults falling short of the Recommended Dietary Allowance (RDA).
Why Is Magnesium Deficiency So Common?
- Modern agriculture has depleted our soil of magnesium, so plants (and animals that eat them) contain less.
- Processed foods — which make up the bulk of the modern diet — are stripped of minerals.
- Stress, caffeine, alcohol, certain medications, and sugar all increase magnesium excretion.
- Most multivitamins either lack magnesium or contain forms with poor absorption.
Even people trying to eat a whole-foods, nutrient-dense diet may struggle to get enough, especially if they have higher needs due to exercise, stress, or underlying conditions.
What Magnesium Supports:
- Nervous system regulation and resilience to stress
- Muscle relaxation and prevention of cramps or twitching
- Heart rhythm stability
- Sleep quality and circadian rhythm regulation
- Blood sugar control
- Bone strength (working hand-in-hand with Vitamin D)
Fringe Magnesium Mix is formulated with bioavailable forms (including glycinate, orotate, and malate), making it gentle on digestion and effective at raising magnesium in the body.
In short: If you’re not actively supplementing with magnesium, there’s a good chance you’re not getting enough.
3. Electrolyte + Mineral Mix: What Water Is Missing
Most people think of electrolytes only when they’re sweating — but these charged minerals are always working behind the scenes to keep your body in balance.
What Are Electrolytes?
Electrolytes are minerals that carry an electric charge. They’re critical for:
- Hydration
- Muscle contractions (including your heart)
- Nerve signaling
- pH balance
- Nutrient transport in and out of cells
The key players include sodium, potassium, magnesium, calcium, and chloride.
The Hidden Problem: Modern Water Is Mineral-Empty
Our ancestors drank natural water from springs and rivers — water that picked up minerals as it flowed over rocks and through earth. This water was a meaningful source of nutrients, especially calcium and magnesium.
Today, most of us drink filtered, distilled, or reverse-osmosis water. While necessary to remove contaminants like lead, arsenic, or chlorine, these processes also remove beneficial minerals.
According to the World Health Organization (WHO), natural water can contribute 1% to 20% of daily intake for key minerals. Removing them leaves us not only with nutrient gaps, but with “hungry” water that can actually pull minerals from the body.
Filtered water has been linked to:
- Increased mineral losses in urine, sweat, and feces
- Reduced hydration (water is less retained)
- Impaired electrolyte homeostasis
Why Supplementing Electrolytes Daily Makes Sense
Fringe Electrolyte + Mineral Mix is formulated to:
- Re-mineralize filtered or RO water
- Restore hydration balance
- Support energy production and exercise recovery
- Replenish electrolytes lost via sweat, urination, or stress
- Help offset mineral-poor modern diets
It’s a simple, effective way to bring your drinking water closer to what nature intended.
In short: Supplementing with electrolytes daily helps restore the essential minerals missing from modern, filtered water — supporting hydration; energy, nerve and muscle function; and overall mineral balance.
Why We Chose These 3 as Our Essentials
You might be wondering: Why these three? Why not include more?
Here’s what makes them “Essential”:
- They’re fundamental – They address chronic, widespread deficiencies.
- They’re backed by science – There are decades of research supporting their safety and benefits
- They’re difficult to get from nature in our modern world – Because of depletion of soil, water, and our indoor lifestyles, the nature-based sources of these nutrients are hard to access.
They’re interconnected – Magnesium and Vitamin D work together; electrolytes and magnesium support hydration and muscle function; and vitamin K2 ensures D3 doesn’t misplace calcium.
It’s true that some people would benefit from taking additional supplements. But these are the three that most people need most often. Our future plans include developing supplements for special populations, but we’re committed to always being transparent about who would (and would not) benefit from taking them. Our primary goal isn’t to sell products – it’s to educate, support, and empower people to enjoy optimal health as naturally as possible.
What Makes Fringe “Essentials” Supplements Unique?
There are a lot of supplements out there. So, what makes Fringe’s Essentials line stand out?
Here’s what sets our Essentials apart:
Better Forms of Nutrients – Backed by Science
Vegan Vitamin D3
Unlike most D3 supplements sourced from lanolin (derived from sheep’s wool), ours is 100% vegan, derived from sustainable lichen.
MK-7 Vitamin K2
We use the most bioavailable, long-acting form of Vitamin K2, shown to stay active in the body for up to 48 hours and effectively direct calcium into bones and away from arteries.
Water-Soluble DK Formula
Most fat-soluble vitamins are difficult to absorb without food. Our DK is designed for optimal absorption even without fat in a meal, supporting consistency and convenience.
Three Forms of Magnesium
Our Magnesium Mix contains a thoughtful blend of magnesium glycinate, malate, and orotate — three highly bioavailable forms that are gentle on digestion and support energy, calm, muscle, and cardiovascular health.
Electrolytes + Trace Minerals
Our Electrolyte & Mineral Mix includes a broad spectrum of trace minerals, not just sodium and potassium. These support everything from thyroid health to enzymatic function and help mimic the natural balance found in spring water.
Clean Formulations
We skip all the unnecessary extras found in most supplements:
- No natural flavors
- No stevia or artificial sweeteners
- No sugar
- No gums or thickeners
- No unnecessary fillers
- No soy, dairy, or gluten
Our belief is simple: If your body doesn’t need it, it doesn’t belong in your supplement.
Our Small Scoops Mission
One of our core values is helping people feel better, without overwhelming them with capsules or giant scoops. That’s why we’ve committed to our Small Scoops Mission.
We formulate our powders to be low in volume and high in impact, so they can easily be mixed into water, added to a smoothie, or even mixed into foods. No giant tubs or 4-pills-a-day protocols. Just what your body needs, in a form you’ll actually want to use.
Final Thoughts
Health doesn’t have to be complicated. Sometimes, it’s about giving your body the basic building blocks it needs with consistency.
Fringe’s Essentials line isn’t about treating symptoms. It’s about supporting your body’s capacity to thrive by filling in modern-day nutrient gaps with the most foundational support we can offer.
Because sometimes, feeling better starts with getting back to what’s essential.
