Product Description

Calcium L-Threonate is a highly bioavailable organic calcium salt formed from L-threonic acid, a metabolite of vitamin C. It is designed to improve calcium absorption efficiency and support bone health, making it suitable for use in dietary supplements, functional foods, and nutraceutical formulations.

Compared with inorganic calcium sources, Calcium L-Threonate offers better solubility and gentler gastrointestinal tolerance, making it ideal for long-term calcium supplementation products.
