Label names and ingredient questions
Look for E625, E 625, or the ingredient name. Related names and label terms include magnesium glutamate. A family code can cover more than one specified form; check the full declaration when the distinction matters.
Check the complete nutrition label when comparing mineral intake. The name of a flavor enhancer does not disclose the amount of elemental magnesium per serving.
Is E625 safe?
EFSA’s 2017 review set a group intake limit and identified potential exceedance in some population groups. EFSA glutamate assessment (2017).
A label identifies the ingredient but usually not its concentration. Calculating daily intake requires the amount in the food and the quantities eaten.
