Frequently Asked Questions

What is the difference between Vitamin K1, K2 MK-4, and K2 MK-7?

K1 (phylloquinone) is found in leafy vegetables. K2 MK-4 is a short-chain menaquinone. K2 MK-7 (menaquinone-7) is the long-chain form derived from natto fermentation, with a half-life of 72+ hours in the blood.*

Why is the D3 + K2 combination so popular?

Vitamin D3 increases calcium absorption from the gut, while vitamin K2 (as MK-7) is involved in directing calcium into bone tissue. D3 and K2 are a popular pairing for bone support.*

Can I take K2 MK-7 if I am on warfarin?

No — not without medical supervision. Vitamin K2 (and K1) activate blood clotting factors, which can directly interfere with warfarin's anticoagulant mechanism. If you take warfarin or any other anticoagulant, consult your physician or haematologist before adding any vitamin K supplement to your regimen.
