Calcium is a mineral that helps us make strong bones and teeth. Most of the calcium in our bodies is in our bones. We spend almost half of our lives (30 to 35 years) building to a peak bone mass. Taking in enough calcium helps younger people build strong bones. Maintaining a safe calcium level helps older people limit bone loss.
