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.
Safety profile
JECFA's group ADI for glutamic acid and its salts is 'not specified' (1987), meaning no numerical limit, and JECFA notes that intake of magnesium glutamate is limited by its laxative action. In 2017 EFSA set a group ADI of 30 mg/kg body weight per day for glutamic acid and its salts (E620–E625), expressed as glutamic acid. Same safety profile as the other glutamates. The magnesium contribution is small relative to typical dietary intake but adds at high doses.
