What is Calcium Dihydrogen Phosphate?

[KAL-cee-um  DI-hy-dro-gen faas-FATE]

Calcium dihydrogen phosphate is a specific form of calcium phosphate that is very similar to monocalcium phosphate. All three ingredients are so similar that their Ingredient Interpreter stories are identical.

Calcium dihydrogen phosphate is added to infant formula to provide the essential minerals calcium and phosphorus.

More than Bone Health

Calcium phosphate is the form of calcium that is found in bones and teeth. While we often think of calcium’s role in building strong bones, it is also needed to conduct messages along the nervous system, move all our muscles, and release hormones. Like calcium, the mineral phosphorus is well known for its contributions to bone health; however, it is also a core part of ATP, a chemical that provides energy for all metabolic processes.

Regulations and Safety

In the United States, calcium phosphate is generally recognized as safe (GRAS). In Europe, calcium phosphates are known as E341 in the E number system of substances that can be added to foods.  The World Health Organization considers it safe, as do Australia and New Zealand.

The FDA Infant Formula Act requires formulas sold in the United States to have at least 60 milligrams (mg) calcium for every 100 calories prepared formula. A maximum level of calcium has not been established. Formulas must also have at least 30 mg phosphorus per 100 calorie prepared formula.

The European Commission requires calcium content to be between 50 and 140 mg and phosphorus between 25 and 90 mg per 100 calories formula.

Dietary Considerations

All religious groups, vegans, and vegetarians can consume calcium phosphate. It is not sourced from animal bones.
