Each Of The Following: Calcium Carbonate

Calcium carbonate is a common chemical compound found naturally in rocks like limestone and marble. It is also present in seashells and eggshells. For food use, it is typically manufactured from purified mineral sources.

Manufacturers add calcium carbonate as a source of calcium, a nutrient. It also functions as an anti-caking agent, preventing powders from clumping, and as a dough conditioner in baked goods. It is commonly found in cereals, baked goods, and some processed foods.

In the U.S., calcium carbonate is Generally Recognized As Safe (GRAS) by the FDA for use as a nutrient supplement and food additive. It is a source of dietary calcium, which is essential for bone health. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated calcium carbonate. Evidence does not suggest adverse health effects at typical dietary intake levels.
