Health Benefits of Vitamin K2

Vitamin K2, also know as menaquinone, is a fat-soluble vitamin. This essential nutrient is found in certain foods and dietary supplements. Bacteria in our gut also converts the dietary form of vitamin K1 into vitamin K2.

The main role of Vitamin K2 in the body is to help activate the hormone osteocalcin, which helps deposit calcium into bones. Vitamin K2 also activates a group of proteins called ‘matrix GLA proteins’ which prevent calcium from being deposited into the walls of arteries.
