Magnesium Diglutamate
The short version
The magnesium salt of glutamate — used in some specialty seasonings and supplements.
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 magnesium hydroxide. Less common than the sodium or potassium salts.
How it's used
Used where mineral magnesium content is also desired — in specialty seasoning blends and certain supplement formulations. Identical umami activity to MSG.
Safety profile
No ADI specified. Same safety profile as the other glutamates. The magnesium contribution is small relative to typical dietary intake but adds at high doses.
Physical & chemical properties
White crystalline powder, soluble in water. Provides the same free glutamate that activates umami receptors.
Regulation worldwide
Permitted globally.
