Allergy Research Esrerol is a customised formulation of Ester-C® with bioflavonoids. Ester-C® is a patented nutritional product that contains ascorbic acid and calcium demonstrated to enhance absorption and retention of vitamin C. This formulation is non-acidic and minimally irritating to the intestines. Esterol also provides 3 types of bioflavonoids - quercetin, rutin, and proanthocyanidins.
As a dietary supplement, 1 or 2 capsules one to three times daily between meals, or as directed by a healthcare practitioner.
Esterol is better tolerated by some individuals than pure ascorbic acid. However, Esterol may not be suitable for the severely allergic, as the vitamin C from which it is made is ultimately prepared from corn.
