Hydroxyapatite (HA) is a naturally occurring mineral form of calcium apatite with the formula Ca5(PO4)3(OH), but it is usually written Ca10(PO4)6(OH)2. Pure hydroxylapatite powder is white. Naturally occurring apatite can, however, also have brown, yellow, or green colorations. Calcium hydroxyapatite is a complete bone building food. Calcium hydroxyapatite can help to reduce bone loss and is the most easily absorbed calcium source. The mineral component of bones and teeth, it has been used therapeutically as a prosthetic aid and in the prevention and treatment of osteoporosis.
