When you think of coffee beans, it’s probably the roasted variety that comes to mind: deep brown in color, heady in aroma. But prior to roasting, the coffee beans are actually green and rich in a natural chemical compound called chlorogenic acid. It’s this ingredient that’s purported to reduce weight. American Formulators standardizes each of their green-coffee-bean extract supplements to contain 50% of this key ingredient; the rest of the veggie capsule remains free of fillers, binders, and porterhouse steaks shaped like broccoli. Take one capsule twice a day 30 minutes before meals. The caffeine amount in each capsule is less than half a cup of coffee.
