Calcium-rich supplement with phosphorus, boron, and vitamin D. Vitamin D promotes the absorption and utilization of calcium and phosphorus, which, combined with one another, contribute to the maintenance of normal bones and teeth. Calcium may be helpful in reducing bone mineral loss in post-menopausal women aged 50 and over, where low bone mineral density is a risk factor for osteoporotic fractures*. Calcium and vitamin D also contribute to the maintenance of muscle function and are involved in cell division processes. Calcium, finally, contributes to normal neurotransmission and blood clotting and, combined with phosphorus, supports energy metabolism. * The beneficial effect can be obtained by taking at least 1200 mg of calcium daily, from all sources.
