@fify-- Why don't you take ECGC capsules? This is the main beneficial ingredient in green tea. ECGC capsules are more potent than green tea capsules and more effective in my opinion.
Also, green tea capsules have caffeine and ECGC capsules don't. Some people don't want the caffeine and some do, so you can pick your supplement based on what you prefer.
Either way, green tea capsules are much better than drinking green tea because I can never drink enough to get the maximum benefits.
