MK-7, Vitamin K2 as MK-7, 90 mcg, 60 Softgels, Jarrow Formulas

90 mcg of natural MK-7 Vitamin K2 from natto fermentation — the most bioavailable and longest-acting form of K2, activating the proteins that direct calcium into bones and keep it out of arteries.

Why

Calcium on its own isn’t enough for strong bones — your body also needs something to tell that calcium where to go. That’s exactly what Vitamin K2 does. Without enough K2, calcium can deposit in the wrong places: in your arteries instead of your bones, contributing to stiffness and cardiovascular risk rather than bone strength. K2 activates two key proteins that manage this: osteocalcin pulls calcium into bones and teeth where it belongs, and matrix Gla protein keeps it out of arterial walls. MK-7 (menaquinone-7) is the form that stays active in your body the longest — with a half-life of around 72 hours, a single daily dose maintains active K2 levels around the clock. Compare that to MK-4, which clears your system within hours. Jarrow Formulas produces their MK-7 through the same traditional natto fermentation process (Bacillus subtilis subsp. natto) used in Japan for centuries — the richest natural source of K2 known. Delivered in a softgel with MCT oil and olive oil for optimal fat-soluble absorption. Note: contains bovine gelatin — not suitable for vegans or vegetarians.
