Description

Calcium Dihydrogen Di-L-Aspartate is a highly bioavailable, chelated form of calcium bound to two molecules of the amino acid L-aspartic acid. This specific molecular structure enhances mineral absorption and stability, making it a superior choice for applications requiring high bioavailability and low reactivity. It is primarily utilized in the pharmaceutical and nutraceutical industries for dietary supplements, as well as in food fortification and specialized biochemical research. Our supply ensures consistent quality and reliable global availability for industrial-scale procurement.

Application

• Dietary Supplements & Nutraceuticals: A key active ingredient in calcium supplements, capsules, and tablets due to its excellent bioavailability and gentle effect on the digestive system.
• Pharmaceutical Formulations: Used in the development of prescription and over-the-counter (OTC) medications for calcium deficiency and bone health management.
• Functional Food & Beverage Fortification: Incorporated into dairy alternatives, sports nutrition products, juices, and baked goods to enhance their nutritional calcium content.
• Animal Nutrition (Feed Premixes): Serves as a premium calcium source in feed for livestock, poultry, and pets to support skeletal development and metabolic functions.
• Biochemical Research & Cell Culture: Employed in laboratory settings as a defined calcium source in media and buffers for studying cellular processes.
• Cosmeceuticals: Formulated into topical creams and serums aimed at supporting skin health and barrier function.

Quality Control

Our Calcium Dihydrogen Di-L-Aspartate is manufactured under a quality management system and undergoes rigorous analytical testing to ensure it meets stringent specifications for identity, purity, and composition. We can supply grades compliant with relevant standards for food and pharmaceutical applications. A comprehensive Certificate of Analysis (COA) documenting purity, heavy metals, residual solvents, and microbiological parameters is provided with each batch.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive). Keep the container tightly sealed in a dry environment to prevent caking or degradation due to moisture absorption.
