• Hygroscopicity: Slightly hygroscopic in ambient air; store in a tightly sealed container in a dry place.

Main Chemical Uses & Applications

1. Pharmaceuticals & Healthcare Products: High-Efficiency New-Generation Calcium Supplement (Main Application)

   • Prevention & Treatment of Osteoporosis: As a highly effective source of calcium, it not only replenishes calcium ions, but its metabolite, L-threonate, also stimulates cellular vitamin C uptake and promotes bone collagen synthesis, thereby significantly increasing bone density and improving bone quality.

   • High Intestinal Absorption Rate: Absorbed through dedicated passive diffusion and active transport pathways in the gut, its absorption rate is significantly higher than that of inorganic calcium (e.g., calcium carbonate). It causes minimal gastrointestinal irritation and carries a very low risk of constipation or kidney stones.

2. Nutritional Fortifiers & Food Additives

   • Widely added to functional beverages, dairy products, infant formulas, and dietary supplement tablets or capsules as a premium dietary calcium source
