Vitamin K

Vitamin K,” the fat-soluble vitamin with a common chemical structure of 2-methyl-1,4-naphthoquinone, naturally present in foods and available as a dietary supplement. These compounds include

  • Phylloquinone (vitamin K1)
  • Menaquinones (vitamin K2). Menaquinones have unsaturated isoprenyl side chains and are designated as MK-4 through MK-13, based on the length of their side chain. MK-4, MK-7, and MK-9.

Vitamin K and blood clotting

Vitamin k helps to make 13 proteins that have a role in blood clotting, which helps prevent your wounds from continuously bleeding so they can heal quickly. The body needs vitamin K to produce prothrombin, a protein and clotting factor important in blood clotting and bone metabolism.

Vitamin K and CVD

Vitamin K helps in producing matrix Gla proteins (MGP), which may  help prevent calcification or hardening of heart arteries,

Vitamin K and bone health

Vitamin K helps in the production of proteins in bone, including osteocalcin, which is required to prevent the weakening of bones. Vitamin K is an essential nutrient that works with calcium to build strong bones.  People who have higher blood levels of vitamin K have higher bone density.

Recommended amount of Vitamin K

The AI amount is estimated to ensure nutritional adequacy. For adults 19 years and older, the AI for vitamin K is 120 micrograms (mcg) daily for men and 90 mcg for women and for those who are pregnant or lactating.

Vitamin K rich food

•          Phylloquinone is present primarily in green leafy vegetables and is the main dietary form of vitamin K

•          Menaquinones, which are primarily of bacterial origin, are present in large amounts in various animal and fermented foods. Almost all menaquinones, especially the long-chain menaquinones, are also produced by bacteria in the human gut.

•          MK-4 is unique in that the body produces it from phylloquinone via a conversion process that does not involve bacterial action.
