Nutrition supplements
Used as a magnesium source after confirming composition, dosage and market requirements.
Food grade ingredient · Citrate salt
Magnesium citrate is a magnesium salt of citric acid used in suitable foods, supplements and premixes as a magnesium source.

Product overview
The commercial reference identifies magnesium citrate by CAS 144-23-0 and formula Mg3C12H10O14, with a reference magnesium-content range of 14.0–16.5% on a dry basis.
The commercial reference 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
Confirm legal use, dosage, technical performance and sensory impact in the finished product.
Used as a magnesium source after confirming composition, dosage and market requirements.
Evaluate magnesium contribution, taste and compatibility in qualifying foods.
Assess solubility, sediment, acidity and sensory effects.
Specify magnesium basis, particle size, hydrate form and contaminants.
Evaluate flow, compression and uniformity in the finished dosage form.
Non-food formulations require separate grade and application qualification; this page concerns food-grade procurement.
Commercial specifications
These commercial reference limits are separate from batch COA results. Agree the grade, analytical basis and applicable standard before ordering.

Specification note: Commercial magnesium citrate may vary in hydration and stoichiometry. The overview describes magnesium content, while the table labels its 14.0–16.5% field as magnesium citrate content. Agree the measured analyte, chemical identity, hydration form and dry-basis method before acceptance, together with the loss-on-drying method and market requirements.
Qualification support
Request the current specification/TDS, SDS, methods and representative or batch COA.
Verify applicable HACCP, Kosher, Halal and ISO documents for the exact product and site.
Review the NIH PubChem magnesium citrate record for identity context.
