Microcrystalline hydroxyapatite is a calcium supplement with a high concentration of hydroxyl ions. This type of calcium is more useful by the body as it is easier to absorb. Hydroxyapatite is the main component of tooth enamel and is used as a graft material in dental and orthopedic surgery.
According to the Weston A Foundation - a non-profit, charitable foundation founded in 1999 for the dissemination of nutritional studies and research - the most effective calcium hydroxyapatite is the microcrystalline hydroxyapatite collagen (MCH) extracted from oleander. These cows are fed naturally and are not burdened with antibiotics, pesticides, hormones or other toxic chemicals.
NOW calcium microcrystalline hydroxyapatite (MCHA or MCHC) is extracted from cattle from Australian organic farms. NOW Calcium Hydroxyapatite formulation contains calcium, phosphorus, magnesium, proteins, minerals and amino acids that are normally found in bone tissue.
