Calcium and bones: MedlinePlus Medical Encyclopedia

The mineral calcium helps your muscles, nerves, and cells work normally. Your body also needs calcium (as well as phosphorus) to make healthy bones. Bones are the main storage site of calcium in the body. Your body cannot make calcium. The body only gets the calcium it needs through the food you eat, or from supplements.
