Description
Calcium L-Aspartate is a highly bioavailable, organically-bound calcium salt of the essential amino acid L-Aspartic acid. This compound is valued for its superior absorption profile and stability compared to inorganic calcium sources, making it an effective nutritional and functional ingredient. It is primarily utilized in the formulation of dietary supplements, functional foods, and pharmaceutical preparations targeting bone health and mineral fortification.
Application
- Dietary Supplements: A key ingredient in calcium supplements, multivitamin/mineral complexes, and bone support formulas due to its excellent bioavailability and gentle effect on the digestive system.
- Functional Food & Beverage Fortification: Used to enrich products like dairy alternatives, juices, cereal bars, and sports nutrition products with a highly absorbable form of calcium.
- Pharmaceutical Preparations: Employed in the development of tablets, capsules, and effervescent formulations for the prevention and treatment of calcium deficiency and osteoporosis.
- Animal Nutrition (Feed Additives): Incorporated into premixes and feed for livestock, poultry, and pets to support skeletal development, eggshell quality, and overall metabolic functions.
- Cosmeceuticals: Found in skincare products for its potential role in supporting skin barrier function and cellular regeneration.
- Chelated Mineral Source: Serves as a model for well-tolerated, amino acid-chelated minerals in advanced nutritional science research and product development.
