What it is

Vitamin K2 is a fat-soluble vitamin that plays a role in bone and heart health. It is found naturally in some animal products like egg yolks and butter, and also produced by bacteria. Some forms of Vitamin K2 are synthesized for use in supplements and fortified foods.

Health notes

Research suggests Vitamin K2 is important for bone health by helping direct calcium to bones and teeth. Some studies also indicate a potential role in cardiovascular health, though more research is ongoing.
