Description

Vitamin K is a group of fat-soluble vitamins found in foods and in dietary supplements. It is present in the form of phylloquinone (vitamin K1) and menaquinones (vitamin K2). Phylloquinone is present primarily in green leafy vegetables and is the main dietary form of vitamin K while Menaquinones, which are predominantly of bacterial origin, are present in modest amounts in various animal-based and fermented foods. The most common sources of vitamin K are spinach, broccoli, and fats and oils, particularly soybean and canola oil.

Health benefits

  • Vitamin K is a cofactor for osteocalcin, one of the main proteins in bone. It helps to maintain bone mineral density and reduces the chances of osteoporosis. (1)
  • Matrix Gla-protein (MGP) is a vitamin K-dependent protein that may play a role in the prevention of vascular calcification. Vascular calcification is one of the major causes of coronary heart diseases. (1)
  • Increased blood levels of vitamin K have been linked with improved episodic memory in older adults. (2)
  • Giving vitamin K1 by mouth or as a shot into the muscle helps to prevent bleeding problems in newborns. (3)
  • Taking a specific form of vitamin K2 seems to improve bone strength and reduce the risk of fracture in older women with weak bones. (3)

Note

Vitamin K can have a serious and potentially dangerous interaction with anticoagulants such as warfarin. Bile acid sequestrants, such as cholestyramine can reduce the absorption of vitamin K and other fat-soluble vitamins. (1)
