Esterol (Ester-c with bioflavonoids) We often recommend this form of vitamin C because of the extra antioxidants it provides. It very powerfully supports immune system function.

• Ester-C« is a patented nutritional product that contains ascorbic acid together with clinically significant metabolites and calcium.
• Ester-C« is highly bioavailable, and is well retained in the blood after it has been absorbed.
• Esterol is better tolerated by some individuals than are ascorbic acid crystals. However, Esterol may not be suitable for the severely allergic, as the vitamin C from which it is made is prepared from corn.
• In addition to being a well tolerated source of vitamin C, Esterol also provides 3 types of bioflavonoids-quercetin, rutin, and proanthocyanidins. The bioflavonoids are water-soluble antioxidants that were discovered by Szent-Gyorgyi in plants, almost simultaneously with his discovery of vitamin C. Quercetin and rutin are well-recognized; the proanthocyanidins are highly bioavailable and are particularly potent antioxidants.
