Description

Magnesium Fumarate is the magnesium salt of fumaric acid, a key compound valued for its role as a mineral supplement and functional excipient. Its primary commercial significance lies in providing bioavailable magnesium in a stable, non-hygroscopic form compared to other salts, which is critical for product shelf-life and efficacy. This product is essential for manufacturers in the pharmaceutical, nutraceutical, and functional food industries seeking a reliable source of magnesium for tablet and capsule formulations.

Application

• Pharmaceutical Tableting: Used as a source of magnesium in mineral supplement tablets and as a diluent or flow aid in solid dosage forms.
• Nutraceutical Formulations: A key active ingredient in magnesium capsules, powders, and chewable supplements for dietary deficiency correction.
• Functional Food Fortification: Incorporated into food products like cereals, beverages, and health bars to enhance magnesium content.
• Animal Feed Premixes: Serves as a nutritional additive in feed for livestock, poultry, and pets to support bone health and metabolic functions.
• Cosmetic Applications: Utilized in personal care products for its skin-conditioning properties.
