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

Jarrow Formulas MK-7 — 90 mcg of Vitamin K2 as natural MK-7 (Menaquinone-7) per softgel, produced via fermentation by Bacillus subtilis subsp. natto — the same traditional process used to make Japanese Natto. The most bioavailable and longest-acting form of Vitamin K2, 10x better absorbed than K1 from spinach. Supports bone health and cardiovascular health. 60 softgels — 60-day supply.

Why you need it

Here’s something most people don’t know: calcium on its own isn’t enough for strong bones. Your body also needs something to tell that calcium where to go — and that’s exactly what Vitamin K2 does. Without enough K2, calcium can end up in the wrong places: depositing 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 traffic. Osteocalcin pulls calcium into your bones and teeth where it belongs. Matrix Gla protein keeps it out of your arterial walls. Together, they make K2 one of the most important nutrients for both bone density and heart health — yet most people don’t get nearly enough from diet alone.

Not all K2 is equal either. 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 keeps your K2 levels topped up 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 that’s been used in Japan for centuries — the richest natural source of K2 known. Delivered in a softgel with MCT oil and olive oil so your body can absorb every drop.

Note: contains bovine gelatin — not suitable for vegans or vegetarians.
