†Supports bone mineral composition; reduces risk of osteoporosis *Calcium microcrystalline hydroxyapatite is a calcium compound which contains a mixture of minerals in their natural ratios, as well as residues of matrix, proteins, and glycosaminoglycans. Calcium microcrystalline hydroxyapatite supports bone mineral composition. †Risk factors for osteoporosis include sex, race, age and inadequate calcium intake. Populations at highest risk for osteoporosis include Caucasian, Asian, postmenopausal women, and elderly women and men. Adequate calcium intake throughout life is linked to a reduced risk of osteoporosis, as calcium helps to optimize peak bone mass during adolescence and early adulthood in conjunction with exercise and healthy diet. Calcium intake greater than 2,000 mg per day has no further known benefit to bone health.
