A green coffee extract is an extract of unroasted, green coffee beans. Green coffee extract has been used as a weight-loss supplement and as an ingredient in other weight-loss products. Its efficacy and mechanism of action have been the subject of controversy.
There is tentative evidence of benefit; however, the quality of the evidence is poor. In 2014 one of the primary trials showing benefit was retracted and the company that sponsored the study, Applied Food Sciences, was fined by the Federal Trade Commission for making baseless weight-loss claims using the flawed study.
Green coffee extract is sold under various proprietary brand names including Svetol, and is included in weight-loss products such as CoffeeSlender.
Health effects:-
A 2011 review found tentative evidence that green coffee extract promotes weight loss; however, the quality of the evidence was poor. This review looked at three published randomized controlled trials of green coffee extract, totaling 142 participants, and found a small effect. The review stated that more rigorous trials with longer duration were needed to assess the efficacy and safety of green coffee as a weight loss supplement. Participants in the studies were instructed to restrict their diet and increase their exercise in addition to taking the supplement.
One of the trials was retracted in 2014 because the accuracy of the data was unclear.
History:-
In April and September 2012, The Dr. Oz Show featured green coffee extract, and conducted its own non-scientific study as to its efficacy. The guest on that show, Lindsey Duncan, has been fined $9 million by the Federal Trade Commission for making deceptive and unsubstantiated claims related to green coffee products promoted on The Dr. Oz Show.
Svetol was developed by Berkem, a French phytochemical and plant extract company. The product was first marketed as a dietary supplement in 2002. By 2005 it was the active ingredient in CoffeeSlender, a popular weight-loss product in Norway, and the product launched in the UK the following year. At the 2006 Health Ingredients Europe conference it received the Bronze Award in the best ingredient category.
In January 2008, Naturex, an international natural ingredient manufacturer, acquired Berkem’s clinically tested plant extract division, of which a prime product was Svetol, and Naturex brought Svetol to the U.S. market.
Svetol is one of the two brands of green coffee extract that is standardized to contain at least 45% chlorogenic acid. (unreliable source?][unreliable source?] In 2013 EuroPharma added Svetol to its line.
