Why Vitamin K for Bone & Joint

For bone & joint support, Vitamin K is a supporting ingredient backed by research. K1 (phylloquinone) primarily supports blood clotting, while K2 (menaquinones) directs calcium into bones and teeth rather than arteries. Among K2 forms, MK-7 has a much longer half-life (~96 hours vs 1–8 hours for MK-4), making it far more effective for bone density and cardiovascular health at lower doses.

How much vitamin k do you need

Research points to 90–200 mcg as the effective range for vitamin k. MK-7 supplements typically provide 100–200 mcg. Lower doses may provide some benefit, but most studies showing clear results used this range.
