Direct product answer
What is food grade magnesium citrate?
The supplied magnesium citrate is identified by CAS 144-23-0 and formula Mg3C12H10O14, with a reference magnesium-content range of 14.0–16.5% on a dry basis.
The supplied commercial limits must be matched to the exact grade, intended food category and destination-market rules. A product name alone does not establish regulatory conformity.
Application screening
Common food grade Magnesium Citrate applications
