Product Information

  • 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
  • The calcium in Ester-C provides part of your daily calcium requirements
  • Ester-C 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
  • Less acidic and easier on the stomach than ascorbic acid
  • Enhanced with quercetin, a bioflavonoid and powerful antioxidant with anti-inflammatory and anti-histamine properties
  • Added bioflavonoids from berry fruits for superior vitamin C absorption
  • Arabinogalactan is a type of polysaccharide that offers additional immune support during stressful times and the cold and flu season
  • Ester-C has a clinically proven higher bioavailability and retention rate than other forms of vitamin C
  • Formulated with citrus-free ingredients for people wishing to avoid citrus
