A combination of vitamin D3 and K2

to support the normal function of the immune system, muscles and bones.

Vitamin D3

D3 (cholecalciferol) is the form the body naturally creates in the skin thanks to the sun — D2 (ergocalciferol) comes from plants and fungi. D3 is significantly more effective than D2 at raising and maintaining blood levels of 25(OH)D. That is why we choose D3 as our standard.

Vitamin K2

Vitamin D increases the absorption of calcium and activates the proteins that direct this calcium the right way — into the bones (osteocalcin), not into the blood vessels (matrix Gla protein). Without enough vitamin K2, however, these proteins cannot fulfil their function, because they need K2-dependent carboxylation to do so. That is why we combine D3 with K2 in the form of MK-7 in the product — a natural and well-absorbed form that the ordinary Western diet contains almost none of.

1 capsule a day

One capsule a day gives you the amount of vitamin D3 recommended by the European Football Association UEFA.

Support your muscles and immunity where it matters most

Vitamin D3 is directly involved in the renewal and repair of muscle tissue after demanding training and strengthens the normal function of the immune system. At the same time, vitamin K2 (MK-7) ensures that the calcium mobilised by vitamin D is deposited correctly in the bones, not in the blood vessels. Together they form the basic pair for faster recovery and stable performance throughout the whole season.

Why is vitamin D3 important for athletes?

In athletes it plays a key role mainly where you would not expect it: it is not just about bones, but above all about muscles and immunity. Vitamin D is involved in the recovery and renewal of muscle tissue after demanding training and supports the normal functioning of the immune system, which translates into less illness during the season.

Why isn't diet alone enough?


Vitamin D is not a classic "vitamin from food" — it is a hormone that the body primarily produces in the skin thanks to UVB radiation. 80–90 % of our vitamin D needs come from the sun, the remaining 10-20 % we can get from a normal diet. Above the 40th parallel the sun is practically unusable for synthesis from autumn to spring, and even people living in warmer climates often suffer from a deficiency because of an "indoor" life.

How much vitamin D3 do athletes need?

Standard dose: 2000 IU/day of vitamin D3

  • The daily dose recommended by the European Football Association (UEFA) or used, for example, for the British & Irish Lions rugby teams
  • Corrects the deficit in 95 % of the population
  • Safely below the EFSA upper limit of 4000 IU/day
  • In most athletes it reaches the target value of >75 nmol/l (25(OH)D)

More information

hyve D3+K2 was created for all athletes who want to support recovery, immunity and long-term health with a scientifically proven approach to vitamin D supplementation.

Scientifically proven effect

Studies show that a daily dose of 2000 IU of vitamin D3 raises the blood level of 25(OH)D above the threshold of 75 nmol/l, which is associated with optimal immune protection and faster recovery after exercise. In research, athletes with levels above 120 nmol/l showed a markedly shorter and milder course of colds compared with athletes with insufficient levels.

Suitable for competitive and recreational athletes training all year round – especially in the period from autumn to spring, when sunlight in Central Europe is not enough for the natural production of vitamin D in the skin.

How does vitamin D3 work?

Vitamin D3 (cholecalciferol) is the form the body creates naturally in the skin thanks to UVB radiation – which is why the body uses it more efficiently than the plant-based D2 form. In the body it is further converted into the active form, which binds to receptors (VDR) that are present in muscle and immune cells as well. The result is support for the renewal and remodelling of muscle tissue after training loads and support for the normal function of the immune system.

Why the combination with vitamin K2

Vitamin D increases the absorption of calcium in the body. Vitamin K2 (MK-7) activates proteins (osteocalcin, matrix Gla protein) that direct this calcium correctly into the bones – without enough K2 there is a risk that it is also deposited outside bone tissue. The D3 + K2 combination therefore supports not only the muscles and immunity, but also the long-term health of the bones and blood vessels.

Frequently asked questions

Get the most out of the product

When to take it

  • Daily, ideally with a meal containing fat (vitamin D is fat-soluble, so it is absorbed better that way)
  • All year round, but it matters most from autumn to spring (in our part of the world practically October–April), when the sun in Europe is not enough for the natural production of vitamin D in the skin
  • In summer, with enough sun exposure, the need may be lower, but supplementation remains a sensible safeguard even then, because an indoor lifestyle limits synthesis anyway
  • This is a long-term matter, not a one-off — regular daily (or equivalent weekly) dosing is recommended, not occasional "bombs"
  • Testing 25(OH)D levels (if the athlete has it done) is recommended seasonally — in autumn, in midwinter and at the end of winter — so that you can see whether the dosing keeps you above the target value of >75 nmol/l

1 capsule = 2000 IU of vitamin D3 + 75 µg of vitamin K2 (MK-7)

This combination:

  • Corrects the deficit in 95 % of the population and sits safely below the EFSA upper limit of 4000 IU/day
  • In most athletes it reaches the target value of >75 nmol/l 25(OH)D
  • 75 µg of K2 is the dose used in the same protocol to ensure the correct activation of osteocalcin and matrix Gla protein

Endurance athletes (runners, triathletes, cyclists) training in Europe, especially in the autumn–spring period, when sun exposure is minimal.

Strength athletes with an indoor lifestyle or training mostly indoors, where even in summer there is not enough UVB exposure.

Those who are working on recovery after exercise — vitamin D takes part in the repair and rebuilding of muscle tissue after training.

Athletes in winter preparation who want to reduce the risk of catching a cold and support the immune system during the season.

Anyone who wants to support the long-term health of their bones and blood vessels — thanks to the combination with K2, which directs calcium to where it belongs.

Yes, at the recommended dose of 2000 IU of D3 a day the product is safe for long-term use.

Why 2000 IU/day is a safe dose

  • Safely below the EFSA upper limit of 4000 IU/day
  • According to the US Institute of Medicine, toxicity is associated only with 25(OH)D levels above 180 nmol/l — with supplementation of 2000 IU/day such values are not reached.
  • It is a dose proven in practice (a protocol used for example for the British & Irish Lions)

Why it is important to stick to a daily rather than a bolus dose

  • Vitamin D is fat-soluble and is stored in fatty tissue — the body is set up for a steady supply, not one-off mega doses.
  • High bolus doses (35 000–70 000 IU/week) in the study by Owens et al. (2018) raised the catabolic metabolite 24,25(OH)D, which can suppress the active form of vitamin D — and this effect persisted even after the supplementation was stopped
