Calcium provides the building blocks that help keep bones and teeth strong and healthy.* It also supports the health of musculoskeletal and nervous systems.* Magnesium helps to regulate calcium transport and stimulates the secretion of calcitonin, a hormone that aids in the influx of calcium into bone.* It plays an important role in protein formation and healthy muscle function.* This formulation also contains Zinc, a trace mineral that plays a role in the synthesis of collagen in bone tissue. Adequate Calcium as part of a healthful diet, along with physical activity, may reduce the risk of osteoporosis in later life.
