Risk level on the Yenzo Scalelow?Based on EFSA's scientific assessment, 2017
EFSA (2017) found that intake in some population groups can exceed the ADI. On the Yenzo Scale this finding does not raise the risk level by itself.
How much a day stays within the ADI?EFSA 2017: 30 mg/kg bw per day
about 2.0 g a daythat is 1,950 mg

Questions about magnesium diglutamate
Is magnesium diglutamate harmful?
In 2017 EFSA set a group ADI of 30 mg/kg body weight a day (expressed as glutamic acid) for glutamic acid and the glutamates E620–625. EFSA noted that intake from additives exceeded the ADI in some scenarios; counting also the glutamate naturally present in food, intake exceeded the ADI at the mean and high (P95) level in all population groups except the mean for the elderly. The biggest contributors were fine bakery wares, soups and broths, sauces, meat and meat products, seasonings and food supplements.
Is INS 625 permitted in Vietnam?
Yes. Magnesium di-L-glutamate (INS 625) is listed in Appendix 1 of Circular 24/2019/TT-BYT, the list of additives permitted in food, with the function flavour enhancer.
