Quercetin
I'm sure everyone remembers hearing their mother say, an apple a day keeps the doctor away. Well, science has proved that mom was absolutely right. Apples are a rich source of a potent flavonoid called Quercetin. This powerful antioxidant supports the immune system by neutralizing free radicals before they can damage cells. Quercetin is also being studied for its antihistamine properties; and its inflammatory properties. Research suggests that Quercetin may also assist the body in maintaining cardiovascular, ocular, respiratory and vascular health.
