Caroline, here is the link to the study about MK7 that I mentioned in my first post on this thread.

An excerpt:

“The three-year study, published first online in Thrombosis and Haemostasis, included 244 healthy postmenopausal women aged 55-65 years. Subjects were randomly assigned to either 180 mcg of MenaQ7 daily or placebo. Using pulse wave velocity and ultrasound analysis, researchers determined that vitamin K2 not only inhibited age-related stiffening of artery walls but also achieved “unprecedented statistically significant improvement” in vascular elasticity. Vermeer says these results confirm vitamin K2’s contributions toward improving cardiovascular outcomes.”

Kiwi33, sometimes the message is more important than the messenger.
