Vitamin K1, also called phylloquinone or phytonadione, is a fat soluble vitamin. Phylloquinone is a cofactor of the enzyme γ-carboxylase, which modifies and activates precursors to coagulation factors II, VII, IX, and X. It is indicated in the treatment of coagulation disorders due to faulty formation of coagulation factors II, VII, IX, and X caused by deficiency or interference in the activity of vitamin K. Phylloquinone has been synthesized since at least 1939, and was approved by the FDA prior to 1955.
