Description

L-Aspartic Acid Zinc Salt is a coordination compound formed from the essential amino acid L-aspartic acid and the essential mineral zinc. This product is valued for its role as a bioavailable source of zinc, offering enhanced stability and absorption characteristics compared to inorganic zinc salts. It is primarily utilized in the formulation of high-quality dietary supplements, functional foods, and pharmaceutical preparations where precise mineral delivery and compatibility are critical.

Application

• Dietary Supplements & Nutraceuticals: A key ingredient in zinc supplements, multivitamin/mineral complexes, and specialized formulations targeting immune support, metabolic function, and skin health.
• Pharmaceutical Preparations: Used in solid dosage forms (tablets, capsules) and liquid formulations as a source of zinc for therapeutic applications and mineral fortification.
• Functional Food & Beverage Fortification: Incorporated into health drinks, meal replacements, cereals, and other fortified food products to enhance their nutritional zinc content.
• Animal Nutrition (Feed Premixes): Serves as an organic trace mineral source in premium livestock, poultry, and aquaculture feed to support growth, reproduction, and overall animal wellness.
• Cosmetic & Personal Care: Found in topical creams, lotions, and ointments for its potential skin-soothing and astringent properties.
• Research & Development: Employed in biochemical research, as a standard in analytical testing, and in the development of novel chelated mineral delivery systems.

Quality Control

Our L-Aspartic Acid Zinc Salt is manufactured under a strict quality management system. Each batch is tested to ensure it meets high-purity standards suitable for nutraceutical and pharmaceutical applications. We provide comprehensive Certificates of Analysis (COA) that detail key parameters such as assay (zinc and aspartate content), heavy metals, residual solvents, and microbiological limits. Specifications can be aligned with FCC, USP, or other relevant pharmacopeial standards upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
