Calcium carbonate is a chemical compound with the chemical formula CaCO3.  It is a common substance found in rock in all parts of the world, and is the main component of shells of marine organisms, snails, pearls, and eggshells.  Calcium carbonate is the active ingredient in agricultural lime, and is usually the principal cause of hard water.    It is commonly used medicinally as a calcium supplement or as an antacid, but excessive consumption can be hazardous.

 

Calcium carbonate is widely used medicinally as an expensive dietary calcium supplement or gastric antacid.  It may be used as a phosphate binder for the treatment of hyperphosphatermia (primarily in patients with chronic renal failure).  It is also used in the pharmaceuticals.  Calcium carbonate is used in the production of toothpaste and has seen resurgence as a food preservative and color retiner, when used in or with products such as organic apples or food.

 

As a food additive, it is designated E170.  It is used in some soy milk products a s source of dietary calcium;  one study suggests that calcium carbonate might be as bioavailable as the calcium in cow’s milk.  Calcium carbonate is also used as firming agent in may canned or bottled vegetable products.
