Magnesium diglutamate

Magnesium diglutamate (CAS 18543-68-5) is the magnesium salt of glutamic acid, commercially known under names including Glutamag and Magnesium-Verla. It does not carry an E-number and is distinct from monosodium glutamate, though it shares the same amino acid backbone. The molecular formula is C10H14MgN2O8 with a tetrahydrate form common in commercial supply.

In food and nutrition applications, magnesium diglutamate functions as a flavour enhancer by activating umami taste receptors, delivering both glutamate activity and a bioavailable magnesium source in a single ingredient. In pharmaceutical and nutraceutical formulations, it serves as a mineral supplement where the glutamate ligand is selected to improve magnesium absorption relative to inorganic salts.

Magnesium diglutamate is supplied in food-grade and pharmaceutical-grade forms and is subject to REACH registration requirements for EU market supply. Procurement quantities are typically available in kilogram to multi-tonne packaging. Buyers should confirm grade specification against FCC or in-house monograph requirements prior to ordering.
