Green coffee bean has strong anti-oxidant properties similar to other natural anti-oxidants like green tea and grape seed extract. These beans have polyphenols which act to help reduce free oxygen radicals in the body. Nutri-Fusion Systems brings you Pure Green Coffee Bean Extract, now with GCA, in a veggie capsule. Green coffee beans contain a special component called chlorogenic acid. Chlorogenic acid has been shown to inhibit the release of glucose while at the same time boosting metabolism. These two mechanisms work synergistically to inhibit fat absorption and eliminate weight gain. Green Coffee Bean Extract can be used as part of an overall wellness program.
