Microcrystalline Hydroxyapatite (M.C.H.A.), also known as Micro-crystalline Calcium Hydroxyapatite Complex (M.C.H.C.), is derived from raw bone and prepared by a special low temperature process (below 37° C) to preserve the protein content. The calcium thus provided is in an extremely bioavailable form. Vitamin D3 is because it is required for the absorption and utilization of calcium and phosphorus and is especially important for normal growth and development of bones and teeth. Vitamin K (both K1 and K2) is added support the synthesis of osteocalcin, the protein in bone tissue upon which calcium crystallizes.* However, because of its role in blood clotting, patients who have a problem in this area or who are taking medications to prevent blood clotting must carefully monitor their intake of vitamin K.

For an MCHC product without vitamin K, see #834.
