How do calcium supplements work?

Calcium can work in many ways, and sometimes the exact way it works may be unclear. In conditions where a calcium deficiency is the problem, taking calcium supplements can help restore calcium to your body, which helps bone and teeth strength as well as organ function. When treating heartburn and indigestion, calcium carbonate behaves like an antacid to neutralize the acid and to relieve symptoms. People with kidney disease are at risk for or have high phosphate levels take calcium to prevent phosphate from being absorbed by binding to it in the gut. Calcium may help relieve PMS symptoms by boosting the lower calcium levels that occur before menstruation. Though it hasn't been proven, calcium may lower blood pressure by making the kidneys dispose of more sodium, which can cause high blood pressure, in urine. Theoretically, calcium may promote weight loss by boosting the breakdown of fatty tissue and making it more difficult for the body to form it.
