Is Dicalcium Phosphate Safe in Supplements?

Dicalcium phosphate is a common additive in many products, from food to pharmaceuticals. In the realm of supplements, it is often used as a filler, binder, or calcium source. But is it safe?

What is Dicalcium Phosphate?

Dicalcium phosphate is an inorganic compound with the chemical formula CaHPO₄. It is a white powder that is insoluble in water but soluble in dilute acids. In its pure form, it is odorless and tasteless.

Uses of Dicalcium Phosphate in Supplements

Filler: Perhaps the most common use of dicalcium phosphate in supplements is as a filler. It helps to increase the bulk of a tablet or capsule, making it easier to manufacture and handle.
Binder: Dicalcium phosphate also acts as a binder, helping to hold the ingredients of a supplement together. This is particularly important for powdered supplements.
Calcium Source: As its name suggests, dicalcium phosphate is a source of calcium. However, it is not as bioavailable as some other forms of calcium, such as calcium citrate or calcium carbonate.

The short answer is: yes, dicalcium phosphate is generally considered safe for human consumption. It has a long history of use in food and pharmaceuticals and has been granted Generally Recognized As Safe (GRAS) status by the U.S. Food and Drug Administration (FDA).

However, as with any substance, there is always a potential for adverse reactions. Some individuals may experience mild gastrointestinal upset, such as constipation or bloating when taking supplements containing dicalcium phosphate.

Potential Side Effects

Gastrointestinal upset: This is the most common side effect associated with dicalcium phosphate. It can cause constipation, bloating, and gas.
Kidney stones: In rare cases, high doses of calcium supplements, including those containing dicalcium phosphate, may contribute to the formation of kidney stones.

Conclusion

Dicalcium phosphate is a safe and effective additive that is widely used in the supplement industry. It serves a variety of purposes, including acting as a filler, binder, and calcium source. While it is generally well-tolerated, some individuals may experience mild gastrointestinal side effects.
