Product Details
Your bones ache. Your muscles feel weak for no clear reason. You're fatigued in a way that doesn't make sense, your joints are stiff, and you keep getting sick. These aren't random — they're classic signs of two of the most widespread nutrient deficiencies in the world.
Vitamin D3 regulates calcium absorption, immune defence, muscle function, and energy metabolism. But D3 alone is only half the picture. Without Vitamin K2, the calcium D3 mobilises doesn't reach your bones — it deposits into your arteries instead, stiffening vessels and straining your heart.
Together, D3 and K2 fix the problem at the source. One formula, doing what neither vitamin can do alone.
Stronger bones. Healthier arteries. Less fatigue. Better immunity.
Aevion Health's D3+K2 delivers 10,000 IU of cholecalciferol and 200 mcg of MK-7 — the most bioavailable, longest-acting forms of each nutrient — in a single daily softgel carried in coconut oil for maximum fat-soluble absorption. 300 softgels per bottle. No fillers. No compromises.
- 3rd Party Tested — Every batch independently verified for purity and potency
- GMP Certified — Manufactured in an FDA-registered, Good Manufacturing Practice facility
- No Fillers — Zero magnesium stearate, silicon dioxide, or artificial flow agents
- Full Label Transparency — No proprietary blends. Every dose disclosed.
How It Works — The Ingredients
10,000 IU Vitamin D3 — Cholecalciferol
The bioidentical form of Vitamin D your skin produces from sunlight. Cholecalciferol is the most effective form at raising D levels in the blood — regulating calcium absorption, immune defence, muscle function, and mood. Most people are chronically deficient without knowing it.
200 mcg Vitamin K2 — MK-7
The longest-acting form of K2, with a half-life of 72 hours. MK-7 activates the proteins that direct calcium into your bones and out of your arteries — making it essential, not optional, when taking high-dose D3. Without it, calcium ends up where you don't want it.
Coconut Oil — Absorption Carrier
D3 and K2 are fat-soluble. Without a fat source, a significant portion of each dose is wasted. Coconut oil ensures both nutrients are properly absorbed — the way clinical studies actually administer them.
How To Use
Take 1 softgel daily with food and drink. For best results:
- Take consistently — the benefits of D3 and K2 are cumulative. Most users notice improvements in energy, strength, and wellbeing within 4–6 weeks of daily use.
- Take with a meal containing healthy fats to further support absorption.
- Pair with regular movement and time outdoors for compounded benefit.
If you are pregnant, breastfeeding, or taking prescription medication, consult your healthcare provider before use.
Why D3K2 — The Science
The deficiency problem is bigger than you think
Vitamin D deficiency is one of the most prevalent nutritional problems in the world, affecting an estimated 1 billion+ people. It doesn't just cause low energy. Chronic deficiency is linked to accelerated bone loss, impaired immune function, muscle weakness, cardiovascular disease, and depression. Standard sunlight exposure and diet are rarely sufficient — particularly in modern desk-job and indoor lifestyles.
Why D3, not D2
Not all Vitamin D is equal. D2 — the form found in most fortified foods — raises blood levels at roughly a third of the rate of D3. Cholecalciferol, the D3 form used in this formula, is bioidentical to what your skin synthesises from sunlight. It is the form used in virtually every significant clinical trial on Vitamin D supplementation.
The calcium problem nobody talks about
Here's what most people are never told. High-dose D3 significantly increases calcium absorption. That calcium has to go somewhere.
Without Vitamin K2, it doesn't reliably go to your bones — it circulates in the bloodstream and deposits into soft tissues and arterial walls. This is known as vascular calcification, and it's a meaningful cardiovascular risk factor.
K2 — specifically the MK-7 form — activates two critical proteins: osteocalcin, which binds calcium into bone, and matrix Gla-protein (MGP), which actively removes calcium from arterial walls. A landmark three-year trial published in Thrombosis and Haemostasis found that MK-7 supplementation significantly reduced arterial stiffness in healthy postmenopausal women. A separate study in the Journal of Bone and Mineral Research demonstrated meaningful improvements in bone mineral density with combined D3 and K2 versus D3 alone.
The bottom line
D3 and K2 are not two separate supplements that happen to be combined. One drives calcium into the body. The other ensures it ends up in the right place.
Taken together, they address bone density, cardiovascular health, immune resilience, muscle function, and energy — at the root, not the surface.

The science does not lie
Dr. Jan O. Aaseth, MD, PhD
One of Europe's leading researchers on vitamins D and K, Dr. Aaseth's 2024 peer-reviewed paper published in Nutrients examined the combined role of vitamins K and D in calcium metabolism and bone health across decades of clinical data.
His findings are direct: adequate vitamin K status is required for the carboxylation of both osteocalcin and matrix Gla-protein — the two proteins responsible for directing calcium into bone and away from arterial walls.
His review draws a clear conclusion: combined supplementation with vitamin K on top of an optimal vitamin D status appears to add meaningful benefit for maintaining bone health — beyond what either vitamin achieves alone. Critically, his work highlights the underappreciated cardiovascular risk of taking D3 in isolation: without K2, increased calcium absorption can contribute to vascular calcification rather than bone mineralisation.
Prof. Grace A. McComsey, MD
Vice President of Research, University Hospitals Cleveland Medical Center
Prof. McComsey's 2025 randomised controlled trial found combined K2+D3 supplementation delivered meaningful reductions in systemic inflammation and improved gut integrity over 24 weeks — with an excellent safety profile throughout.
Prof. Leon Schurgers, PhD
Maastricht University
Prof. Schurgers' research shows that in most Western adults, the protein responsible for protecting arteries from calcification is functionally inactive — due to K2 deficiency. K2 isn't optional. It's the difference between calcium building bones and calcium hardening arteries.
Prof. Michael F. Holick, MD, PhD
Boston University School of Medicine
One of the world's foremost authorities on Vitamin D. Prof. Holick's research underpins the Endocrine Society's clinical guidelines on D3 supplementation — and he has identified vitamin D deficiency as one of the most common, most overlooked medical conditions in the world.

The foundation your body was always missing
What To Expect In Your First 12 Weeks
The Foundation Forms
D3 begins entering your bloodstream and accumulating in tissue. Most users notice subtle shifts first — slightly more stable energy through the day, less of that mid-afternoon crash. Your immune system starts receiving signals it may have been missing for years.
Energy & Mood Lift
Blood levels of D3 are rising meaningfully. Fatigue starts to ease. Mood stabilises — D3 plays a direct role in serotonin production, and many users notice a clearer, lighter feeling during this window. Muscle aches begin to subside.
Strength & Resilience
D3 is now supporting muscle fibre function at a cellular level. Physical strength improves, recovery feels easier, and the body feels less depleted after exertion. K2 is actively redirecting calcium into bone — the structural work is well underway.
The Compound Effect
This is where consistent users report the most significant change. Energy is stable. Immunity feels stronger. Bones and muscles feel more solid. The cumulative effect of D3 and K2 working together is now operating at full capacity.
Your New Baseline
The goal of D3+K2 isn't a temporary boost — it's restoring what your body has been missing. At this point, most users describe feeling noticeably stronger, more energised, and more resilient than they have in years.
Individual results may vary. Timeline reflects published clinical research on D3 and K2 supplementation.
