Menadione is a fat-soluble vitamin precursor that is converted into menaquinone in the liver. The primary known function of vitamin K is to assist in the normal clotting of blood, but it may also play a role in normal bone calcificaton. Vitamin K is primarily found in green leafy vegetables, but also in lesser amounts in some dairy products, meat, eggs, and fruits.
