What are calcium supplements used for?

Calcium is used in a variety of ways, some of which are more effective than others. The medical community generally supports calcium supplements to:

  • supply extra calcium to pregnant women, nursing mothers, adolescents, and children who don't get all the calcium they need from food
  • treat and prevent osteoporosis and other bone disease
  • treat indigestion and heartburn
  • treat hyperphosphatemia (a condition where there is too much phosphate in your bloodstream)
  • treating hypocalcemia (a condition where calcium levels are too low in the bloodstream)
  • help build strong bones in unborn children during pregnancy
  • prevent the symptoms of premenstrual syndrome (PMS)

Other calcium uses are more controversial because of a lack of scientific evidence, but research is ongoing. It has been suggested that calcium supplements may help:

  • decrease blood pressure
  • decrease the symptoms of fluorosis (high fluoride) in overexposed children
  • decrease bad (LDL) cholesterol
  • increase good (HDL) cholesterol
  • encourage weight loss
  • prevent colorectal cancer
  • prevent strokes in women
  • prevent tooth loss in older people
  • reduce the risk of high blood pressure during pregnancy and preeclampsia

Talking to your doctor or pharmacist may help you decide whether a calcium supplement may be helpful for you.
