Up to 50% by volume and 70% by weight of human bone is a modified form of hydroxyapatite, known as bone mineral. [7] Carbonated calcium-deficient hydroxyapatite is the main mineral of which dental enamel and dentin are composed. Hydroxyapatite crystals are also found in pathological calcifications such as those found in breast tumors, [8] as ...
Coral calcium is composed of calcium carbonate and trace minerals. Claims for health benefits unique to coral calcium have been discredited. Coral calcium, marketed as a cure for various diseases and linked to Okinawan longevity, is merely calcium carbonate, and it supposed superiority to regular calcium carbonate has not been proven.
The two major components of bone are hydroxyapatite [Ca10(PO4)6(OH)2], and collagen fibers. Hydroxyapatite, which is one of the most stable forms of calcium phosphate, makes up about 60 to 65 percent of the bone. [5] The rest of the bone is composed of materials including chondroitin sulfate, keratan sulfate and lipid. [5]
Bone meal (or bonemeal) is a mixture of finely and coarsely ground animal bones and slaughter-house waste products. [1] It is used as a dietary supplement to supply calcium and phosphorus to monogastric livestock in the form of hydroxyapatite. As a slow-release organic fertilizer, it supplies phosphorus, calcium, and a small amount of nitrogen ...
P11-4 is a self-assembling β-peptide. It builds a 3-D bio-matrix with binding sites for Calcium-ions serving as nucleation point for hydroxyapatite (tooth mineral) formation. The high affinity to tooth mineral is based on matching distances of Ca-ion binding sites on P11-4 and Ca spacing in the crystal lattice of hydroxyapatite.
Hydroxyapatite, also known as hydroxylapatite, is the major component of tooth enamel and bone mineral. A relatively rare form of apatite in which most of the OH groups are absent and containing many carbonate and acid phosphate substitutions is a large component of bone material. [13]

Calcium is an essential element needed in large quantities. [8] [9] The Ca 2+ ion acts as an electrolyte and is vital to the health of the muscular, circulatory, and digestive systems; is indispensable to the building of bone in the form of hydroxyapatite; and supports synthesis and function of blood
