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.

Benefits of taking Green coffee bean extract


Weight loss

Green coffee bean extracts help to release fatty acids from stored body fats, as well as aid the liver in dispensing fatty acids, which help burn off the excess fat the body has.

The effect of chlorogenic acid enriched coffee on glucose absorption in healthy volunteers and its effect on body mass when used long-term in overweight and obese people.

J Int Med Res. 2007. Thom E. ETC Research and Development, Oslo, Norway.

The results from a clinical study performed in 12 healthy volunteers with different coffee products containing glucose show that instant coffee enriched with chlorogenic acid induced a reduction in the absorption of glucose of 6.9% compared with control. No such effects were seen with normal or decaffeinated instant coffee. In a second, comparative, randomized, double-blind, 12-week study we investigated the effect on the body mass of 30 overweight people, compared with normal instant coffee. The average losses in mass in the chlorogenic acid enriched and normal instant coffee groups were 5.4 and 1.7 kg, respectively. We conclude that chlorogenic acid enriched instant coffee appears to have a significant effect on the absorption and utilization of glucose from the diet. This effect, if the coffee is used for an extended time, may result in reduced body mass and body fat when compared with the use of normal instant coffee.

Boost digestion and metabolism.

By changing the process of how glucose is absorbed in the body, the acids in the green coffee beans help to improve your body’s metabolic rate.

Regulates blood sugar and reduce high blood pressure.

The chlorogenic acids in the bean neutralize free radicals in the body and regenerating vitamin E to control blood sugar levels. They help to reduce high blood pressure levels and are useful in treating hypertension.

Side effects and safety of Green coffee bean extract

Green coffee appears to be safe based on the limited research that has been done in people so far. In clinical research, no serious side effects were reported.
