Ester-C Supreme is a vitamin C supplement that is enhanced with quercetin, arabinogalactins and added bioflavonoids from berry fruits for superior vitamin C absorption.
This formulation includes a unique, patented form of calcium ascorbate, which is made when ascorbic acid (regular vitamin C) is buffered with calcium using a water-based process, and contains active vitamin C metabolites including L-threonate which enhance cellular absorption and retention. Ester-C is the only form of vitamin C that has been proven to last up to 24 hours in the white blood cells of the immune system.
This formula is enhanced with quercetin, a bioflavonoid and powerful antioxidant with anti-inflammatory and anti-histamine properties, and bioflavonoids from berry fruits for superior vitamin C absorption.
