Description

Copper Aspartate is a high-purity, bioavailable coordination compound of copper and the amino acid L-aspartic acid. This specialized ingredient is valued for its role as a stable and effective source of bioavailable copper in nutritional and pharmaceutical formulations. It serves as a critical raw material for manufacturers in the dietary supplement, functional food, and advanced pharmaceutical industries seeking a highly absorbable mineral chelate.

Application

• Dietary Supplements & Nutraceuticals: As a premium source of bioavailable copper in multivitamin/mineral complexes, standalone mineral supplements, and specialized health formulas.
• Pharmaceutical Intermediates: Used in the synthesis of advanced pharmaceutical compounds where a bioavailable copper source is required for efficacy.
• Functional Food & Beverage Fortification: For the enrichment of foods and drinks, such as sports nutrition products and health beverages, due to its stability and bioavailability.
• Animal Nutrition (Feed Premixes): Incorporated into high-quality feed additives for livestock, poultry, and aquaculture to ensure optimal copper nutrition and health.
• Cosmetic & Personal Care Ingredients: Employed in specialized skincare formulations for its potential role in enzymatic processes related to skin health and antioxidant protection.
• Research & Development: Serves as a standard or reagent in biochemical and nutritional research studies investigating copper metabolism and chelation science.

Quality Control

Our Copper Aspartate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for identity, purity, and heavy metal content. Certificates of Analysis (COA) documenting parameters such as assay, specific rotation, and residual solvents are provided with every shipment. We adhere to cGMP principles, and our quality systems support compliance with relevant standards for nutritional and pharmaceutical ingredients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept in its original, sealed packaging until use to prevent absorption of atmospheric moisture, which can affect stability and handling properties.
