Studies have demonstrated that the polyphenols in green tea, particularly the catechin component, offer potent antioxidant activity through the scavenging of free radicals.
Antioxidant supplementation may also offer some protective benefits to the skin from free radical damage. 
Among the polyphenols that are antioxidants in green tea, EGCg and ECG show the strongest effect in reducing collagenase activity—an enzyme that breaks down collagen.1Additional third party research shows that green tea supplementation may help improve lipid and glucose metabolism, maintain normal insulin sensitivity, and support a healthy metabolic rate.1 IngredientsEach capsule contains 250 mg of extract of green tea leaves (Camellia sinensis) standardized to a minimum 97% pure polyphenols including 162 mg catechins, of which 95 mg is EGCg.
