What it is

Calcium carbonate is a mineral that occurs naturally in rocks and is also found in seashells and eggshells. It is commonly produced industrially by passing carbon dioxide through a solution of calcium hydroxide. It is then purified and processed for use in food.

Why it's used

Calcium carbonate is often added to foods as a nutrient supplement, providing calcium. It can also function as an anti-caking agent, preventing powders from clumping, and as a firming agent in some processed fruits and vegetables. It is frequently found in fortified cereals, baked goods, and some dairy alternatives.

Health notes

In the US, calcium carbonate is generally recognized as safe (GRAS) by the FDA when used as a nutrient supplement or anti-caking agent. It is an essential mineral for bone health. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) and the European Food Safety Authority (EFSA) have evaluated calcium carbonate. Typical dietary intakes from food sources are not associated with adverse health effects.

Allergen info

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