Calcium provides the building blocks that help keep bones and teeth strong and healthy. It also plays a role in proper function of the 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. Vitamin D is required to promote calcium absorption, which helps to maintain healthy bones and teeth. Vitamin D also supports a healthy immune system.
