Matti Narkia on 11 Dec 09Research has uncovered the fact that vitamin K also plays a crucial role in maintaining bone health. It was found that the amount of vitamin K required to halt bone absorption leading to osteoporosis requires much greater intakes than that required for blood clot regulation. Further, it appears that bone and vascular tissue (like coronary arteries) maintain a preference for a different form of vitamin K than that required for blood clotting regulation. Rather than vitamin K1 needed for clotting, vitamin K2 is the form preferred by bones and arteries (Schurgers LJ et al 2001). It appears that much of the information generated over the years for vitamin K focused on the K1 form, ignoring the K2 form necessary for bone and vascular health. Normal deposition of calcium occurs only in bone and in teeth. Abnormal deposition of calcium in the body occurs in three places: the inner lining of the arteries of the body (the intima) that causes atherosclerotic plaque; the muscle layer of arteries ("medial calcification"); and heart valves. K2 appears to be the form of vitamin K responsible for controlling these phenomena.
