It is made using a proprietary, water-based manufacturing process which results in a pH neutral product that contains naturally occurring vitamin C metabolites. These metabolites activate the vitamin C molecules, making it easier for the body to transport them from cell to cell for numerous health benefits.*The Science Behind Ester-C: Immune Support*One clinical study showed that Ester-C increased vitamin C levels in the body.1 White blood cell levels of vitamin C were elevated in subjects receiving Ester-C when measured after initial dose. The presence of key metabolites such as threonate may contribute to this increased level and retention of vitamin C by the cells.Non-Acidic and Gentle On the Stomach*In one published study, individuals sensitive to acidic foods were given one gram of vitamin C as ascorbic acid or as Ester-C. Subjects reported heartburn "significantly more frequent and severe after intake of ascorbic acid" and subjects rated Ester-C as tolerated "very good" -- significantly more than ascorbic acid.2 So for anyone who has difficulty tolerating vitamin C, it's comforting to know that Ester-C is non-acidic and gentle on the stomach.*How Can Ester-C Help Me?The main benefit of Ester-C is its quick absorption and retention in the immune system.*What's in the BoxEster-C 500mg.*These statements have not been evaluated by the Food and Drug Administration.
