Nutraceuticals and nootropics for anti-aging

Quercetin’s anti-cancer activity is enhanced by its metabolites.

Quercetin, a flavone found in red wine, green tea, onions, and a variety of fruits and vegetables, has become an exciting nutritional supplement and is the focus of many research studies because of its anti-cancer and cardiovascular-protective effects.

A new study at the University of Leicester has revealed that quercetin does not act alone in providing anti-cancer activity — some of its metabolites are involved, as well. In the body, quercetin is converted into a variety of related substances, including two called ‘isorhamnetin’ and ‘tamarixetin’. Quercetin itself produced a 50% decline in the marker substance used in the Leicester study to measure anti-cancer activity. Isorhamnetin and tamarixetin each produced a 90% decline in this same marker.
