Sports Research Vitamin K2 (MK-7)
by Sports Research
"MenaQ7 vitamin K2 in coconut MCT oil — the calcium-directing vitamin that keeps calcium in bones, not arteries"
Overview
Sports Research Vitamin K2 provides 100mcg of vitamin K2 as MK-7 (MenaQ7) in a coconut MCT oil softgel. MenaQ7 is the most clinically studied form of vitamin K2, with research showing it activates osteocalcin (directing calcium into bones) and matrix GLA protein (preventing calcium from depositing in arteries). Vitamin K2 is the essential partner to vitamin D3 — while D3 increases calcium absorption, K2 ensures that calcium goes to the right places. The coconut MCT oil carrier enhances absorption of this fat-soluble vitamin.
