Esterol is a highly absorbable vitamin C-bioflavonoid mixture.  It contains Ester-C®, a patented, non-acidic mixture of ascorbic acid containing other clinically significant metabolites. Esterol also contains three types of bioflavonoids: rutin, quercetin and proanthocyanidins.


Vitamin C is a very important nutrient we need to consume on a daily basis. It is essential for the proper functioning of many aspects of our health including:


  • The maintenance of the immune system, ensuring it functions properly, especially during and after intense physical exercise
  • The protection of all cells from the potential damage of oxidative stress
  • It is also integral in the regeneration, or the “recycling” of vitamin E
  • The reduction of tiredness and fatigue
  • Our normal psychological function
  • It is also essential for our nervous system to function properly


Vitamin C is a crucial component of ALL collagen formation in the body. Collagen is the main structural protein found in skin and other connective tissue in the body. Therefore, as vitamin C contributes to normal collagen formation it is needed for:


  • The normal function of blood vessels
  • The normal function of cartilage (ligaments, tendons, joints)
  • The normal function of skin, teeth, gums and bones

In studies, the bioflavonoids quercetin, rutin and proanthocyanidins (a polyphenol from grape pips) have demonstrated potent activity protecting cells from oxidative stress. These bioflavonoids and polyphenols are also known to potentiate the antioxidant activity of vitamin C. They all tend to occur naturally together in the foods they are found in.


Ester-C® and calcium ascorbate are highly absorbable forms of vitamin C. Ester-C®, being a non-acidic form of ascorbic acid, is an ideal supplement for those wishing to take larger quantities of vitamin C, or for those who are sensitive to acid-containing foods.

Esterol is suitable for vegetarians and vegans.
