Esterol Ester-C® is a combination of vitamin C in the form of calcium ascorbate and the bioflavonoids quercetin, rutin and proanthocyanidins.


The key benefits of the water soluble antioxidant vitamin C include immune support, as well as to support the body against stress because this essential vitamin is required for the adrenal glands’ production of its hormones. In addition to white blood cell production, Vitamin C is required for histamine release and degradation, the reduction of glutathione, and the metabolism and protection of several other nutrients including vitamin E.

Esterol Ester-C®is formulated with calcium and the bioflavonoids quercetin, rutin and proanthocyanidins. Bioflavonoids work synergistically with vitamin C. Studies indicate that Ester C® is absorbed faster into the bloodstream and white blood cells. In addition, it maintains higher blood and tissue levels than other forms of vitamin C and is excreted in the urine at a slower rate. A recent, not yet published human study at the University of California, Los Angeles, suggests that Ester-C is retained longer than regular vitamin C in white blood cells. Ester C has a pH of 7.0, potentially reducing acidity and improving bowel tolerance.
