Calcium D-Aspartate (also known as D-Aspartic Acid Calcium Chelate, DAACC) is an organic chelated compound formed by the combination of calcium ions and D-aspartic acid, with wide applications in nutritional supplementation and health product development.
Core Basic Information
- Chemical Formula: Anhydrous Ca(CHNO), molecular weight 304.27
- CAS Number: 21059-46-1 (D-Aspartate form), 39162-75-9 (commercial grade)
- Appearance: White crystalline powder, highly soluble in water (≈50g/100ml at 25°C)
- Density: 1.91 g/cm³, stable under normal storage conditions
- Molar Ratio: Calcium bound to D-aspartic acid at 1:2, forming a stable chelate structure
Key Functional Mechanisms
As a bioavailable calcium source, it leverages the unique advantages of D-aspartic acid:
- Enhanced Calcium Absorption: The amino acid carrier enables direct absorption via intestinal amino acid transporters, avoiding gastric acid decomposition, with absorption efficiency 2-3 times that of traditional inorganic calcium salts.
- Targeted Bone Mineralization: Promotes calcium deposition in bone matrix, stimulates osteoblast activity, and increases bone mineral density, reducing osteoporosis risk.
- Dual Physiological Roles:
- Supports muscle protein synthesis, aiding muscle growth and contraction.
- Modulates reproductive hormone levels (e.g., ), with potential benefits for male fertility.
- Participates in energy metabolism via the tricarboxylic acid cycle, alleviating fatigue.
Main Applications
1. Nutritional Supplements
- Core ingredient in bone health products, suitable for middle-aged/elderly individuals, pregnant/lactating women, and those with low dietary calcium intake.
- Fitness and sports nutrition: Supports muscle maintenance and recovery.
2. Food & Beverage Industry
- Used as a nutritional fortifier to enhance calcium content in functional foods, beverages, and health foods.
- Compliant with certifications like ISO9001, ISO22000, KOSHER, and HALAL, suitable for diverse consumer groups.
3. Animal Feed Additives
- Mineral supplement for livestock and poultry, improving growth performance and bone development.
Safety & Usage Notes
- Recommended Dosing: Follow product specifications; excessive intake may cause mild gastrointestinal discomfort.
- Contraindications: Pregnant/nursing women and individuals with pre-existing conditions should consult healthcare providers before use.
- Storage: Keep in a cool, dry, well-ventilated area, away from direct sunlight and contaminants.
