Description

Aspartate Calcium is a chelated mineral compound where calcium is bound to the amino acid L-aspartic acid, enhancing its bioavailability. This specialized form is crucial for applications requiring superior absorption and stability compared to inorganic calcium salts. It serves as a high-performance ingredient for manufacturers in the nutraceutical, pharmaceutical, and functional food industries seeking to fortify their products with a well-tolerated and effective calcium source.

Application

• Dietary Supplements & Nutraceuticals: A key active ingredient in capsules, tablets, and powders designed for bone health, osteoporosis prevention, and general mineral supplementation.
• Functional Food & Beverage Fortification: Used to enrich products like dairy alternatives, juices, cereal bars, and sports nutrition products with bioavailable calcium without compromising taste or texture.
• Pharmaceutical Preparations: Employed in the formulation of prescription and over-the-counter (OTC) medications for calcium deficiency and as a therapeutic mineral source.
• Animal Nutrition (Feed Additives): Incorporated into premixes for livestock, poultry, and pet food to support skeletal development, eggshell quality, and overall metabolic functions.
• Cosmetic & Personal Care: Utilized in topical formulations for its potential skin-conditioning and stabilizing properties.

Quality Control

Our Aspartate Calcium is produced under strict quality management systems. Each batch is tested to ensure it meets stringent specifications for identity, purity, and heavy metal content. We can supply material compliant with relevant standards for dietary supplements and food ingredients. Certificates of Analysis (COA) documenting purity, assay, and other critical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); the original container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
