Vitals Ester-C® 1000 mg (90 tablets) offers a unique form of vitamin C that is gentle on the stomach. Ester-C® is a unique, patented formulation of vitamin C in which calcium ascorbate has already been converted into a form that contains natural metabolites, including threonic acid. These metabolites, with threonic acid leading the way, help improve the absorption and utilization of vitamin C by the body. Furthermore, threonic acid has the special ability to activate vitamin C already present in the body and make it available for use.
