Vitamin K is a family of structurally similar, fat-soluble vitamers found in foods and marketed as dietary supplements. [1] The human body requires vitamin K for post-synthesis modification of certain proteins that are required for blood coagulation ("K" from Danish koagulation, for "coagulation") or for controlling binding of calcium in bones and other tissues.

Vitamin K 2 or menaquinone (MK) (/ ˌ m ɛ n ə ˈ k w ɪ n oʊ n /) is one of three types of vitamin K, the other two being vitamin K 1 (phylloquinone) and K 3 . K 2 is both a tissue and bacterial product (derived from vitamin K 1 in both cases) and is usually found in animal products or fermented foods .
Vitamin K 1-deficiency may occur by disturbed intestinal uptake (such as would occur in a bile duct obstruction), by therapeutic or accidental intake of a vitamin K 1-antagonist such as warfarin, or, very rarely, by nutritional vitamin K 1 deficiency. As a result, Gla-residues are inadequately formed and the Gla-proteins are insufficiently active.
