Description

Magnesium D,L-Hydrogenaspartate Tetrahydrate is a highly bioavailable organic magnesium salt complex. This compound is valued for its superior absorption and utilization profile compared to inorganic magnesium sources, making it an essential ingredient in high-performance nutritional and pharmaceutical formulations. It is primarily sought by manufacturers in the nutraceutical, pharmaceutical, and functional food industries seeking to enhance the efficacy of their magnesium-fortified products.

Application

• Dietary Supplements & Nutraceuticals: As a premium source of bioavailable magnesium in capsules, tablets, and powdered drink mixes for supporting bone health, muscle function, and energy metabolism.
• Pharmaceutical Preparations: Used in the formulation of prescription and over-the-counter (OTC) magnesium supplements and electrolyte replacement therapies.
• Functional Food & Beverage Fortification: Incorporated into sports nutrition products, health drinks, and fortified foods where high solubility and bioavailability are critical.
• Clinical Nutrition: A key component in medical nutrition products, such as enteral feeds and parenteral solutions, designed for patients with magnesium deficiency.
• Cosmetic & Personal Care: Utilized in topical formulations for its potential skin-soothing and anti-inflammatory properties.
• Animal Nutrition (Feed Grade): As a nutritional additive in premium pet food and livestock feed to support animal health and development.
