What is Monopotassium Phosphate?

Monopotassium phosphate is an inorganic compound that combines potassium and phosphate. It is typically synthesized in a laboratory setting by reacting phosphoric acid with potassium hydroxide, resulting in a white, granular substance.

In the food and beverage industry, it serves as a buffering agent, helping to maintain acidity levels, and as a nutrient source, especially in sports drinks and supplements for its potassium content. Health research indicates that it is generally considered safe in typical consumption amounts, but any dietary impacts from excessive potassium should be noted.

When you see monopotassium phosphate on a label, it is often used to balance the electrolytes and nutrient levels in products, particularly in those aiming to support hydration or energy production.

Commonly found in: sports drinks, dietary supplements, processed foods, fertilizers, laboratory reagents

What to watch
