How it helps your body
Quercetin is one of the best studied flavonoids, and has been shown to help your body in multiple avenues. It acts as an antioxidant in multiple ways (directly by scavenging free-radicals and helping activate your body’s antioxidant defenses), can help your body respond to inflammation by reducing cyclooxygenase activity, and is effective at stabilizing mast cells. Plus, it has been shown to increase the effectiveness of other supplements.
Commonly found in: dark green vegetables (kale, wattercress, radish leaves, etc) and fruit (skins of apples and other fruit).
