    Vitamin K2

    Vitamin K is a type of fat-soluble vitamin that is essential for the activation of vitamin K-dependent proteins, and is involved in blood coagulation and tissue calcification in animals. There are two main types of vitamin K, Vitamin K1 (phylloquinone) contained in vegetables and seaweed, and Vitamin K2 (menaquinone-7, MK-7) produced by microoganisms. Nature-MK7 is produced from Bacillus subtilis var. , which is used in traditional oriental fermented foods. Unlike Vitamin K1, Vitamin K2 promotes calcification and, in addition, increases the amount of osteocalcin, a bone hormone in cultured human osteoblasts, and therefore is known to increase bone density and strength.
