menatto® supports healthy blood vessel elasticity*


A randomized, double-blind, placebo-controlled study of healthy post-menopausal women found that 3 years of supplementation with menatto® vitamin K2 (MK-7) supported healthy blood vessel elasticity, benefiting cardiovascular health.*


Observational studies indicate a link between vitamin K2 intake and the health of the heart and vascular system. However, human intervention trials have been lacking. Researchers investigated the effect of menatto® on blood vessel elasticity and function in healthy post-menopausal women.

Study details

For 3 years, 244 healthy post-menopausal women were randomly assigned to take either a placebo or 180 mcg of menatto® per day. Researchers measured the women’s blood vessel elasticity and function with a variety of tests. They also analyzed blood chemistry for markers of cardiovascular health and vitamin K status, including matrix GLA protein (MGP).


menatto® supported healthy blood vessel elasticity by helping maintain MGP in the blood vessel wall.* This action may support healthy blood flow, contributing to cardiovascular health.*
