Brief Introduction：
Vitamin K2, also known as menadione, is a fat-soluble vitamin and one of the indispensable and important vitamins for the human body. In the human body, vitamin K2 is mainly synthesized by intestinal bacteria, and also exists in some animal meat products and fermented products, such as animal liver, fermented milk products and cheese, among which the most abundant source is natto. As a cofactor of γ-glutamine carboxylase, vitamin K2 activates multiple vitamin K-dependent proteins that play key roles in cardiovascular and bone health.
