What it is

Calcium carbonate is a chemical compound that occurs naturally as the mineral calcite. It is also produced industrially for use in food. It is a white powder that is insoluble in water.

Why it's used

Calcium carbonate is used as an anti-caking agent, a colorant, a firming agent, and a nutrient supplement. It is often added to processed foods like baked goods, dairy products, and plant-based beverages to improve texture and provide calcium. It can also be used as a food-grade white pigment.

Health notes

In the U.S., calcium carbonate is Generally Recognized As Safe (GRAS) by the FDA for use in food. It is also a common dietary supplement for calcium intake. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated calcium carbonate. High intake may cause constipation or interfere with calcium absorption.

Calcium carbonate is not derived from any of the nine FDA major allergens. It does not contain gluten.
