Calcium provides the building blocks that help keep bones and teeth strong and healthy. 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 aiding protein formation and healthy muscle function. Zinc is a trace mineral that plays a role in the synthesis of collagen in bone tissue, and supports immune health.
Adequate Calcium as part of a healthful diet, along with physical activity, may reduce the risk of osteoporosis in later life.*
