What is Calcium Carbonate?

[ pronounced: kal-see-um kar-bo-nate  | kal-sē-əm kär-bə-ˌnāt]

Calcium carbonate is found everywhere on earth and even in the earth. In fact, more than 4% of the earth’s crust (hard outer layer) is made up of calcium carbonate. Calcium carbonate is added to infant formula to provide the mineral calcium. This is a very common form of calcium that is found in supplements, antacids, and other medications. Calcium carbonate is also commonly added to nut milks like soy, almond, and cashew.

What Does Calcium Do?

While we often think of calcium’s role in building strong bones and teeth, it is also needed to conduct messages along the nervous system, move all our muscles, and release hormones. Although it is widely dispersed, about 99% of it is found in bones and teeth.  

Regulations and Safety

The FDA Infant Formula Act requires formulas sold in the United States to have at least 60 milligrams (mg) calcium for every 100 calories prepared formula. A maximum level of calcium has not been established.

The European Commission requires calcium content to be between 50 and 140 mg per 100 calories prepared formula.

Dietary Considerations

All religious groups, vegans, and vegetarians can consume calcium carbonate.
