Many people are already familiar with vitamin K as a necessary blood-clotting factor, but Vitamin K has been receiving more attention as research reveals other important roles in the body. For example, vitamin K is also vital for proper mineralization of bone and also helps to prevent the inflammation-related calcification of arteries.

As important as vitamin K is, however, it can be difficult to obtain enough from diet alone. Most of our vitamin K comes from intestinal bacteria (vitamin K2) with a much smaller proportion coming from foods like leafy greens and soy (vitamin K1).

Research suggests that the body can convert K1 into K2, so many people now supplement with 100 mcg a day of K1 to optimize all vitamin K-dependent functions within the body.

MK-7 (menaquinone-7) is a bioactive form of vitamin K2 and plays an critical role in calcium metabolism, and supports cardiovascular health including arterial elasticity.*
