Calcium L-Threonate is a highly bioavailable calcium salt of L-threonic acid, a metabolite of Vitamin C. It is recognized as one of the most effective calcium supplements due to its superior intestinal absorption rate and cellular uptake compared to traditional forms like calcium carbonate or citrate.
Unlike other calcium sources, Calcium Threonate bypasses many absorption issues, making it ideal for supporting bone density, joint strength, and healthy aging. It is widely used in nutraceuticals, functional foods, and clinical research on osteoporosis prevention.
