Vitamin K is a group of fat-soluble vitamins essential for blood clotting and bone metabolism. It plays a crucial role in activating proteins required for these processes, including prothrombin for coagulation and osteocalcin for bone mineralization. Vitamin K exists in two primary forms: K1 (phylloquinone), found in leafy green vegetables, and K2 (menaquinone), found in animal products and fermented foods, and also synthesized by gut bacteria. Adequate intake is necessary to maintain proper physiological function, particularly concerning cardiovascular health and skeletal integrity.
