Complex Vitamin D3 + K2 MK-7 is a D3 + K2 stack built for athletes and high-performers who want consistent recovery, resilience, and performance year-round.

Vitamin D3 supports far more than immunity - it helps maintain normal muscle function, supports recovery under stress, and plays a role in overall hormonal balance. Despite its proven benefits, vitamin D deficiency remains common because modern life keeps us indoors and UVB levels are too low for meaningful production for months at a time. And if you supplement D3 without K2 (MK-7), the job isn’t fully finished: D3 helps your body absorb calcium, while K2 helps direct it where it belongs, into bones and teeth, instead of letting it drift into soft tissues. 

The result is simple: stronger foundations, better day-to-day readiness, and a smarter way to cover the October–April gap when your body can’t reliably make enough vitamin D on its own.

When should I take Vitamin D3+K2 MK-7?

After a meal, ideally after breakfast or lunch.

The presence of fats in the meal significantly increases the absorption of vitamin D from your diet.

How can I tell if I have a vitamin D deficiency?

Go for a blood test.

A blood test is the only way to tell whether your vitamin D level in the blood is optimal.

Is vitamin D safe for children as well?

Yes.

However, the exact dosage should always be consulted with a pediatrician.

Can I take too much vitamin D?

Yes.

That’s why you should always follow the recommended dosage, and consult your doctor before taking higher doses.

I have blood test results, how much vitamin D should I supplement?

Breakdown of ideal supplementation based on blood vitamin D levels:

<20 ng/ml (<50 nmol/l) -> 4,000 to 8,000 IU/day -> 4 to 8 weeks, then re-test

20 to 29 ng/ml (50 to 72.5 nmol/l) -> 2,000 to 4,000 IU/day -> 4 to 8 weeks, then re-test

30 to 50 ng/ml (75 to 125 nmol/l) -> less than 2,000 IU/day -> 4 to 8 weeks, then re-test

50 ng/ml (>125 nmol/l) -> Consume foods rich in vitamin D

However, always consult your doctor about the exact dose.
