Quercetin (pronounced kwer-suh-tin) has been in the news recently, and for good reason. This yellow pigment is a flavonoid that occurs in apples, grape skin, red onions, and green tea.
While quercetin’s presence in foods has long been recognized, it has only been lately that some of its remarkable effects have come to light.
Quercetin’s recently discovered properties include protective effects against cancer, cardiovascular disease, allergies and immune dysfunction — all of which, if prevented, could help improve or extend life.
For life extensionists, however, the most exciting research involves the use of quercetin as a potential treatment for aging.
