Vitamin K2 MK7
TL;DR
Vitamin K2 MK-7 (menaquinone-7) is the most bioavailable and longest-acting form of vitamin K2, derived from natto fermentation. It activates osteocalcin (directing calcium to bones) and matrix Gla protein (preventing arterial calcification).
Overview
Vitamin K2 MK-7 (menaquinone-7) is the most bioavailable and longest-acting form of vitamin K2, derived from natto fermentation. It activates osteocalcin (directing calcium to bones) and matrix Gla protein (preventing arterial calcification). MK-7 has a 72-hour half-life vs 1-2 hours for MK-4, making it superior for daily dosing.

Products with Vitamin K2 MK7
Interactions
synergistic. Vitamin D increases calcium absorption from the gut; K2 activates osteocalcin and matrix GLA protein to direct that calcium into bones rather than soft tissues and arteries
synergistic. K2 activates osteocalcin which binds calcium for bone mineralization; without K2, supplemental calcium may deposit in arteries and soft tissues instead of bones
inhibits. Warfarin works by blocking vitamin K recycling (VKOR); K2 supplementation directly antagonizes warfarin, potentially causing treatment failure and thrombotic events
synergistic. Magnesium supports vitamin K-dependent carboxylation reactions and is required for proper osteocalcin function; the D3+K2+Mg triad is the foundation of bone health
