Vitamins And Minerals: Tricalcium Phosphate

Tricalcium phosphate is a white powder that is a salt of calcium and phosphate. It is found naturally in bones and teeth. In food, it is typically produced from calcium carbonate sources like limestone or oyster shells, and phosphoric acid.

Manufacturers add tricalcium phosphate to foods as an anti-caking agent, to prevent powders from clumping. It also functions as a nutrient supplement, providing calcium and phosphorus. It is commonly found in powdered drink mixes, baked goods, and cereals.

In the U.S., tricalcium phosphate is Generally Recognized As Safe (GRAS) by the FDA for use in food. It is a source of calcium and phosphorus, which are essential nutrients. Both JECFA and EFSA have evaluated tricalcium phosphate and established acceptable daily intakes. Evidence does not suggest adverse health effects from typical dietary intake.
