Description

Magnesium Maleate is the magnesium salt of maleic acid, a compound valued for its role as a source of bioavailable magnesium and as a functional additive. It is particularly significant in the pharmaceutical and nutraceutical industries for formulating high-quality mineral supplements. This product is essential for manufacturers seeking a stable and effective magnesium ingredient for dietary supplements, food fortification, and specialized chemical synthesis.

Application

• Dietary Supplements & Nutraceuticals: A key ingredient in magnesium capsules, tablets, and powder blends to support bone health, muscle function, and energy metabolism.
• Pharmaceutical Formulations: Used as an active pharmaceutical ingredient (API) or excipient in solid dosage forms where magnesium supplementation is clinically indicated.
• Food & Beverage Fortification: Serves as a mineral fortifier in functional foods, sports nutrition products, and health beverages.
• Chemical Synthesis: Acts as a catalyst or a reagent in organic synthesis and polymer chemistry due to the maleate functional group.
• Cosmetic & Personal Care: Incorporated into skincare formulations for its potential skin-conditioning properties.
• Industrial Applications: Utilized in specific catalytic processes or as a stabilizing agent in various chemical manufacturing operations.
