Douglas Laboratories Calcium Microcrystalline Hydroxyapatite Calcium Microcrystalline Hydroxyapatite supplies 500 mg of elemental calcium from 2,000 mg of microcrystalline hydroxyapatite (MCHC), a bioavailable source of calcium derived from whole bone. Ingredients Each serving contains: Vitamin C - 150 mgCalcium (from Microcrystalline Hydroxyapatite) - 500 mgPhosphorus (from Microcrystalline Hydroxyapatite) - 260 mgMicrocrystalline Hydroxyapatit - 2,000 mgBoron (as Boron Citrate/Aspartate) - 5 mg Other ingredients: Cellulose, hydroxypropyl cellulose, carboxymethyl cellulose, stearic acid, vegetable stearate and silica. Suggested Use As a dietary supplement, adults take 2 tablets daily or as directed by your healthcare professional. More Info. The adult human body contains approximately 1,200 g of calcium, about 99% of which is present in the skeleton. Bone is constantly turning over, a continuous process of formation and resorption. In children and adolescents, the rate of formation of bone mineral predominates over the rate of resorption. In later life, resorption predominates over formation. Therefore, in normal aging, there is a gradual loss of bone. It is generally accepted that obtaining enough dietary calcium throughout life supports bone health. Among other factors, such as regular exercise, gender and race, calcium supplementation during childhood and adolescence appears to be a prerequisite for maintaining adequate bone density later in life. Calcium Microcrystalline Hydroxyapatite provides a highly beneficial source of dietary calcium together with other naturally occurring nutrients like phosphorus that assist in the maintenance of healthy bone structure and function, and aids in the absorption of calcium. Boron affects the composition, structure, and strength of bone. It appears to be necessary for calcium and magnesium absorption, their adequate renal reabsorption, and their incorporation into the bone matrix. Boron is absorbed at about 90% efficiency and is rapidly distributed among the tissues.
