    Ester-C provides vitamin C to help in the development and maintenance of bones, cartilage, teeth and gums.
    Ester-C¨ is 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. It 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 also enhanced with quercetin, a powerful bioflavonoid and antioxidant with anti-inflammatory and anti-histamine properties.
