"This fat-loss booster (chlorogenic acid) works synergistically with caffeine to burn the body fat that has been released from storage by caffeine. Look for products that contain 200 to 400 milligrams of green-coffee extract that's been standardized to 50% chlorogenic acid, and take it 2-3 times a day between meals." <Stiefel, Steven, and Chris Logan.

Also if you guys remember I did a product review for Amino Energy, guess what, it has green coffee extract in there! if you haven't seen it yet take a look, I definitely recommend you try it out!
