Description

Calcium Di(L-Lysinate) is a chelated mineral complex where calcium is bound to two molecules of the amino acid L-Lysine, enhancing its bioavailability. This compound is valued for its superior absorption and stability compared to inorganic calcium salts, making it an effective nutritional supplement. It is primarily utilized in the pharmaceutical and nutraceutical industries for formulating dietary supplements, functional foods, and clinical nutrition products aimed at supporting bone health and calcium metabolism.

Application

• Dietary Supplements: As a highly bioavailable source of calcium in capsules, tablets, and softgels for bone and joint health support.
• Functional Food & Beverage Fortification: For enriching products like dairy alternatives, nutritional bars, and meal replacement shakes with a stable, soluble calcium source.
• Clinical Nutrition: Used in medical and enteral nutrition formulas for patients with specific dietary requirements or malabsorption issues.
• Pharmaceutical Preparations: As an active pharmaceutical ingredient (API) or excipient in formulations designed to treat or prevent calcium deficiency.
• Animal Nutrition (Feed Grade): Incorporated into premixes for livestock, poultry, and pet food to promote skeletal development and overall health.
• Cosmetic & Personal Care: Potential use in skincare products for its role in skin barrier function and cellular signaling.

Quality Control

Our Calcium Di(L-Lysinate) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for nutritional and pharmaceutical applications. Certificates of Analysis (COA) documenting key parameters such as assay, heavy metals, and microbiological limits are available upon request. We can supply grades compliant with relevant specifications for dietary supplements.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
