What it is

Monobasic sodium phosphate is a salt made from phosphoric acid and sodium. It is a white, crystalline powder that is soluble in water. It is produced industrially through chemical synthesis.

Why it's used

Manufacturers use monobasic sodium phosphate as an acidity regulator and a buffering agent in foods. It helps control the pH of products, which can affect taste, texture, and shelf life. It is commonly found in powdered drinks, sports drinks, and specialty formula supplements.

Health notes

Monobasic sodium phosphate is generally recognized as safe (GRAS) by the FDA for use in food. It is a source of phosphorus, an essential mineral. The Joint FAO/WHO Expert Committee on Food Additives (JECFA) has evaluated it. Some research suggests that high phosphate intake from processed foods may be linked to health issues in certain populations, but evidence is mixed and more research is needed.

Allergen info

Monobasic sodium phosphate is not derived from any of the nine FDA major allergens. It does not contain gluten.
