Vitamin D and K are structurally similar fat-soluble vitamins. Synergistically, they support healthy calcium metabolism and bone mineralization throughout the body as well as a healthy calcium balance in vascular tissues. Vitamin K also provides critical cardiovascular protection by helping to activate matrix Gla protein (MGP), an inhibitor of circulatory calcification. 
 
This Vitamin D Plus K is a bioavailable combination of 5,000 IU of Vitamin D3 (cholecalciferol) and 100 mcg Vitamin K2 (menaquinone-7, MK7).
