Ester-C® is a natural, non-acidic water-soluble form of vitamin C that is distinguished by its unique chemical composition and biological activity. It is manufactured in an exclusive, water-based process that results in a mixture of naturally occurring vitamin C metabolites, including ascorbate, dehydroascorbate, and threonate. Vitamin C aids in the absorption of iron and the formation of red blood cells. Research indicates that vitamin C supports healthy hemoglobin levels.
