Quercetin is a powerful antioxidant, as well as a natural antihistamine and anti-inflammatory. It is a citrus bioflavonoid, a natural substance that helps protect capillaries, prevent bruising, and intensify the effect of vitamin C in the body – in fact, bioflavonoids are essential for total vitamin C effectiveness.

In a study of adults with symptoms of macular degeneration, moderate red wine consumption (a source of quercetin) offered some protection against the development and progression of the disease.

Dark berries, such as blueberries, blackberries, and cherries, are also high in flavonoids. Animal studies suggest that quercetin inhibits the activity of compounds that contribute to the development of cataracts.
