One capsule of NOW EGCg Green Tea Extract delivers the phytonutrient content equal to about 2-3 cups of green tea. Green Tea Extract contains numerous compounds, including Polyphenols and Catechins, that provide potent antioxidant benefits. One Catechin in particular, EGCg, has demonstrated extraordinary free radical-quenching power in laboratory studies. In non-clinical studies, EGCg has also been shown to be protective against chemical and environmental assault on tissues and helps to support healthy cell cycle regulation.
