Vitamin K is a class of fat-soluble vitamins6. This essential vitamin exists naturally in foods such as leafy, green vegetables and soybeans, and is vital for your body to properly regulate and activate important proteins such as clotting factors in the liver, Matrix Gla Proteins found in your arteries, and osteocalcin in bones.7,8,9,15

Your body utilizes Vitamin K in two forms, Vitamin K1 (phylloquinone) and Vitamin K2 (menaquinones). Vitamin K1 helps blood coagulate/clot properly.18 Whereas, Vitamin K2 helps reduce calcium plaque build up in your arteries and guides calcium absorption to strengthen your bones. Several clinical studies show how Vitamin K2 serves to improve cardiovascular health while simultaneously increasing bone mineral density.4,10
