Dicalcium phosphate is the inert diluent and carrier for Vitamin B12 in fortified organic foods. Monocalcium phosphate is used as a component of chemical leavening agents ("baking powder"). Tricalcium phosphate is commonly used in non-dairy beverages as a source of calcium since these beverages displace cows' milk from the diet.
