Green coffee bean extract is a new ingredient on the market. 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. Green coffee bean extract is sometimes standardized to 30 to 50% chlorogenic acid, a compound present in coffee which has long been known for its beneficial properties. This active ingredient makes green coffee bean 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 bean extract is made from the green beans of the coffea Arabica plant. There are two types of coffee plants, arabica and robusta… the arabica is higher in quality and higher in chlorogenic and caffeic acids, two primary compounds responsible for anti-oxidant activity.
Boiled coffee drinks contain cafestol which is associated with the negative effects of using coffee as a stimulant, this is not present in green coffee beans or the extract. This natural supplement has been mentioned on a Dr. OZ TV program.
