Calcium L-Threonate；CAS 70753-61-6

Calcium threonate is a calcium salt of threnoic acid and a novel drug developed for the treatment of osteoporosis and as a calcium supplement 1. It is found in dietary supplements as a source of L-threonate used in the treatment of calcium deficiency and prevention of osteoporosis. The most common form is calcium L-threonate, or (2R, 3S)-2, 3, 4-trihydroxy butyric acid calcium 1. L-threonate is an active metabolite of vitamin C that mediates a stimulatory action on vitamin C uptake 1. Therapeutic efficacy of calcium threonate in reducing was studied and investigated due to the hypothesis that it may play a role in the mineralization process through its positive action on vitamin C.
