Vitamin K acts primarily in blood clotting, where its presence can make the difference between life and death.Vitamin K is essential for the activation of several proteins. When any of the blood clotting factors is lacking, hemorrhagic disease (uncontrolled bleeding) results.Vitamin K also participates in the metabolism of bone proteins, most notably osteocalcin.Without vitamin K, osteocalcin cannot bind to the minerals that normally form bones, resulting in poor bone mineralization.Vitamin K is stored in the liver.
