Green tea contains much higher concentrations of catechins than black teas, accounting for up to 30% of the dry weight; however, standard brewing methods are insufficient to fully extract them so it may take drinking 10 cups of tea per day to reach the doses of catechins used in studies. A more natural, cold brewed green tea is another potential solution to that problem (available here).
