Vitamin K2 helps keep blood vessels flexible; a link to longevity

In the first study on long-term vitamin K2 supplementation and cardiovascular health, 244 healthy postmenopausal women took 180 mcg of vitamin K2 – menaquinone 7 per day, or a placebo.

After three years, while the placebo group had an increase in blood vessel stiffness, women who took vitamin K2 saw an average 33 percent improvement in blood vessel flexibility. Discussing the findings, doctors said it was remarkable that the women taking vitamin K2 not only did not experience the typical age-related stiffening of the arterial walls, but also saw measurable improvements in vascular elasticity across the entire circulatory system compared to the placebo group. Arterial flexibility has a direct link to longevity.
