Green Coffee Bean Extract is one of the new ingredients on the market for "anti-aging" formulas. Studies show that green coffee bean extract may have stronger anti-oxidant properties than other natural anti-oxidants such as green tea and grape seed extract. Chlorogenic Acid is the compound present in coffee which is believed to confer the majority of these beneficial properties.. Chlorogenic Acid is an excellent agent to absorb free oxygen radicals; as well as helping to avert hydroxyl radicals, both which contribute to degradation of cells in the body. Green coffee beans have other strong polyphenols which also act to help reduce free oxygen radicals in the body. There is also evidence that Chlorogenic Acid may cause the small intestine to alter patterns of glucose uptake, helping to regulate the metabolism.
