Sodium phosphateMonosodium phosphate, Disodium phosphate, Trisodium phosphate

Sodium phosphate is a chemical compound that is commonly used as a food additive, including in protein powders. It is a type of salt that is made up of sodium and phosphate ions, and it comes in several different forms, including monosodium phosphate, disodium phosphate, and trisodium phosphate.

Sodium phosphate is used in protein powders for several reasons. One of its primary functions is as a pH stabilizer, helping to maintain the acidity of the protein powder and prevent it from spoiling. It can also act as a buffering agent, helping to regulate the acidity of the protein powder during the manufacturing process.

In addition, sodium phosphate is sometimes added to protein powders as a source of dietary phosphorus. Phosphorus is an essential mineral that is important for bone health and many other bodily functions.

While sodium phosphate is generally recognized as safe by the US Food and Drug Administration (FDA), it can be harmful in large amounts. Excessive intake of sodium phosphate can lead to a number of health problems, including kidney damage, osteoporosis, and high blood pressure.

Individuals with kidney disease, heart disease, or high blood pressure should consult with their healthcare provider before using protein powders that contain sodium phosphate.
