One capsule of NOW Green Tea Extract with 200 mg EGCg possesses the phytonutrient content equal to about 2-3 cups of green tea. Green Tea Extract contains numerous compounds, including Polyphenols and Catechins, that provide antioxidant benefits.* Laboratory studies suggest that one Catechin in particular, EGCg, may support against free radicals.* Other non-clinical studies suggest EGCg may also be protective against chemical and environmental effects on tissues.
