Vitamins And Minerals: Potassium Chloride

Potassium chloride is a mineral compound that occurs naturally in rocks and salts. It is often produced industrially by reacting potassium hydroxide with hydrochloric acid. It is commonly used as a salt substitute and a source of potassium.

Potassium chloride is frequently added to foods as a potassium supplement and a salt substitute, offering a less salty taste than sodium chloride. It is found in a variety of processed foods, including cereals, baked goods, and snack foods, where it can also act as a flavor enhancer.

Potassium chloride is generally recognized as safe (GRAS) by the FDA when used as a nutrient supplement. The National Academies have established an upper intake level for potassium. JECFA and EFSA have evaluated potassium chloride, and it is considered an essential mineral. While beneficial for blood pressure regulation, excessive intake can be problematic for individuals with kidney issues.
