Vitamin C is a factor in the maintenance of good health, wound healing and in the normal 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
  • 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
  • Ester-C® has a clinically proven higher bioavailability and retention rate than other forms of vitamin C
  • Available in three natural flavours: orange, wildberry
