Calcium is required by the body for maintaining bones, muscles and nervous system. So it is used as a dietary supplement and for treatment of weakening of bones (osteoporosis). Calcium carbonate is used along with vitamin D3 for better absorption. Calcium carbonate is also used as an antacid to relieve acidity/heartburn (acid reflux) and stomach/duodenal ulcer.
Calcium carbonate is a dietary supplement used when the amount of calcium taken in the diet is not enough. It acts by neutralizing acids when taken as antacid.
