MK-7 Vitamin K Supplements

What MK-7 vitamin K2 is

Vitamin K2 belongs to the menaquinone family, and MK-7 is its long-chain, natto-derived form. Compared with the shorter MK-4, MK-7 stays in the bloodstream much longer, so a modest once-daily dose (often 90–120 mcg) is enough to keep levels steady.

K2, D3 and calcium

Vitamins D3 and K2 work as a team in calcium metabolism: D3 supports the absorption of calcium from your diet, while K2 helps activate the proteins that direct that calcium into bone. That partnership is why K2 is valued for bone health and why you’ll so often see D3 and K2 combined in a single product.

Choosing a K2 supplement

• Form — MK-7 is the long-acting, natto-derived option most people choose; MK-4 is shorter-acting and usually taken in higher, more frequent doses.
• On its own or with D3 — standalone K2 lets you tune the dose, while D3+K2 combinations are convenient and cover both nutrients at once.
• Format & label — capsules, softgels and drops are all available, often in an oil base to aid absorption; look for soy-free or non-GMO if that matters to you.
