Dicalcium diphosphate is an acidic phosphate for baking powder and a calcium supplement, limited by the phosphate ADI.

Consumer Advice ​

Dicalcium diphosphate is an inorganic phosphate salt used as an anticaking agent and as a leavening component in baking powder, helping powdered foods stay free-flowing and baked goods rise. It is a calcium salt that is poorly absorbed by the body. It is safe at approved levels for most people, though those with kidney disease or who must limit phosphorus may want to monitor total dietary phosphate intake.
