Potassium Citrate and the Peanut Free Diet

Potassium citrate is a white crystalline powder that functions as a potassium salt of citric acid. It is widely used in the food industry primarily as an acidity regulator, with the E number E332. This compound is also used in the medical field to prevent and treat kidney stones and to manage hypokalemia, a condition characterized by low potassium levels in the body. The citric acid used in potassium citrate is often derived from the fermentation of corn dextrose, which may be a concern for those with corn allergies or intolerances.
