Calcium L-threonate is a calcium salt of L-threonic acid, a naturally occurring sugar acid derived from L-ascorbic acid metabolism. It is produced through a controlled synthesis process, yielding a high-purity crystalline powder that is highly water-soluble and bioavailable. As a premium mineral supplement ingredient, it is standardized to ≥98% purity (HPLC) and meets stringent quality standards for pharmaceutical and nutraceutical applications.
With the growing demand for effective calcium supplementation and cognitive health products, Calcium L-threonate has gained attention as a superior calcium source. Its unique ability to facilitate calcium transport across cell membranes, particularly in the nervous system, positions it as a valuable ingredient in formulations targeting bone health and cognitive function. LyvBio supplies Calcium L-threonate in commercial quantities, backed by comprehensive technical support and regulatory documentation.
