See also Phytonadione for additional information. Vitamin K is a cofactor used to synthesize coagulation factors in the liver (factors II, VII, IX, and X). Vitamin K-1 also is known as phytonadione and phylloquinone (Phytomenadione is the British spelling of Phytonadione). Vitamin K-2 is also known as menaquinone. Vitamin K-3 is known as menadione. Vitamin K-3 is a synthetic analogue and is not equivalent to Vitamin K-1. Vitamin K-3 is not recommended for clinical use. Vitamin K-1 is absorbed better with meals that contain fat.
Vitamin K-1 is a fat-soluble vitamin used to treat coagulopathies caused by anticoagulant toxicosis (warfarin or other rodenticides). Anticoagulants deplete vitamin K in the body, which is essential for synthesis of clotting factors. In large animals, it is used to treat sweet clover poisoning.
