What is Green coffee bean extract?
Green coffee bean extract is a powder formed by grinding green coffee beans. Green coffee beans are simply unroasted coffee beans, which are often grown in Central and South America. These small beans now are being used as supplements to aid in weight loss and were even featured on the Dr. Oz show.
Green coffee bean extract is a relatively new ingredient on the market. It has strong anti-oxidant properties similar to other natural anti-oxidants like green tea and grape seed extract. It has polyphenols, such as chlorogenic acid, which act to help reduce free oxygen radicals in the body.
In March of 2012, Dr. Joe Vinson performed a clinical study with this substance and found a significant connection between consumption of green coffee and fat loss. Vinson speculates that this may be due to chlorogenic acid, which Vinson believes reduces the absorption of glucose and lowers the hyperglycemic peak. Vinson is a chemist at the University of Scranton in Scranton, PA. He says his successful trial results should pave the way for more research on this substance. So, a larger trial is being planned. Dr. Vinson adds that green coffee bean extract may also reduce insulin levels, which would improve metabolism function. He also said there were no indications of negative side effects reported by any of the clinical study participants.
What is chlorogenic acid?
Chlorogenic acid is a common dietary polyphenol found in many plants including certain fruits, green tea and green coffee bean. Chlorogenic acids are major secondary metabolites found in coffee seeds. Chlorogenic acid has a metabolite called m-coumaric acid.
Chlorogenic acids, or CGAs, include a group of closely related chemicals that possess a similar molecular structure. The most abundant chlorogenic acid in coffee is 5-caffeoylquinic acid. Your body metabolizes chlorogenic acid into its component chemicals, quinic acid and caffeic acid. Other CGAs in coffee include dicaffeoylquinic, feruloylquinic and coumaroylquinic acid. The relative concentrations of the various CGAs in coffee beans affect the flavor and aroma of coffee.
In laboratory experiments, chlorogenic acids demonstrate potent antioxidant effects.
