Calcium L-Threonate is a food-grade organic calcium salt of L-threonic acid (a vitamin C metabolite).We supply bulk Calcium L-Threonate sourced from leading China manufacturers, available in powder form for global food and beverage producers. Our Calcium L-Threonate is widely used in osteoporosis-prevention supplements, calcium fortification beverages, women's nutrition, chewable calcium tablets and functional food calcium fortification.
Calcium L-Threonate is produced by reacting calcium with L-threonic acid, a natural metabolite of vitamin C.
The resulting organic calcium salt has excellent water solubility and bioavailability. L-Threonic acid itself promotes collagen synthesis and bone mineralisation, making this form particularly effective for bone-health and osteoporosis-prevention applications.
