                                Hydroxyapatite makes up approximately 97% of tooth enamel and 70% of human bone, acting as the primary mineral component that gives them their hardness and structure. The term 'hydroxyapatite' can be used broadly, but a specific form known as microcrystalline hydroxyapatite (MCHA) offers a unique, more complete nutritional profile for bone health.
