Potassium citrate is considered an allowed synthetic substance for organic food production. Potassium is a necessary dietary mineral for humans, and including potassium in foods can help improve potassium levels. Potassium citrate as a supplement has therapeutic applications, and may help improve calcium status. There is no research showing that its addition to food is harmful. It’s important to note that potassium citrate is made using citric acid, of which the synthetically manufactured form may carry health concerns due to a type of black mold and known allergen, Aspergillus niger, that is used to produce it. There are potential concerns over trace mold exposure from continuous consumption of synthetic citric acid and lack of safety evaluation due to it being used prior to the Food Additives Amendment in 1958. It’s also necessary for patients of chronic kidney disease to pay attention to potassium citrate on food labels, as it is commonly a hidden source of potassium.
