Monopotassium Glutamate
The short version
The potassium salt of glutamate — a low-sodium alternative to MSG.
It's widely considered safe at the amounts used in food, so we mark it green. The Safety section below has the details.
Where it comes from
Produced by neutralizing glutamic acid with potassium hydroxide instead of the more common sodium hydroxide. Used in products targeting reduced sodium content.
How it's used
Found in low-sodium soups, broths, and seasoning blends where MSG's sodium content would conflict with the reduced-sodium claim. Provides identical umami flavor enhancement to MSG.
Safety profile
No ADI specified. Same safety profile as MSG. The potassium contribution can matter for patients with kidney disease or those on potassium-sparing medications.
Physical & chemical properties
White crystalline powder, very soluble in water. Provides the same free glutamate ion that activates umami receptors.
Regulation worldwide
Permitted globally. EU labelling required.
