Svetol is a proprietary standardized chlorogenic acid extract of decaffeinated green coffee beans, sold by Naturex. It is used as a weight-loss supplement and as an ingredient in other weight-loss products. Svetol has been on the market as a dietary supplement since 2002, Svetol is a hydroalcoholic decaffeinated green coffee extract produced from coffee beans of the variety Coffea canephora robusta Pierre. The extract is spray dried and encapsulated. Svetol contains a specific chlorogenic acids profile balanced between 3-, 4-, and 5-caffeoylquinic acid, and contains 45%-50% chlorogenic acids by weight. Efficacy A 2011 systematic review of scientific studies of GCE found a modest increase in weight loss in subjects who took GCE compared to those on the placebo, although the authors doubted whether such a difference would be meaningful to people. The authors said the studies were "of poor methodological quality", pointing to, among other problems, very small sample sizes, very short trial durations and "Two authors in one study were affiliated to a company which markets Svetol but did not specify whether or not they had any conflicts of interest." History Svetol was developed by Berkem, a French phytochemical and plant extract company. The product was first marketed as a dietary supplement in 2002. In January 2008, Naturex, an international natural ingredient manufacturer, acquired Berkem's plant extract division, of which a prime product was Svetol. The acquisition by the larger company boosted the marketing force behind the product, Svetol is one of the two brands of green coffee extract that is standardized to contain at least 45% chlorogenic acid.
