Green coffee bean extract has exploded onto the weight loss market ever since it first made headlines and appeared on "The Dr. Oz Show" in March. When the show returned in September for the fourth season, Dr. Mehmet Oz spoke again about green coffee bean extract for weight loss. He encouraged viewers to look for the words "Svetol" or "GCA" on the nutrition label to know you're getting the best one. But he didn't really say why.
Many of our customers have called with questions like "How are these products different?" or "Are the results different?" So we did a little digging.
What Green Coffee Extract Does
Green coffee beans are simply unroasted coffee beans. By not roasting the beans, you keep their levels of chlorogenic acid intact. Chlorogenic acid has been shown to inhibit glucose formation in the liver, speed up the metabolism and slow fat absorption for weight loss. A study published in the medical journal Diabetes, Metabolic Syndrome and Obesity caught the attention of the news media, stating that participants lost an average of 10 percent of their total body weight, or about 18 pounds in just 12 weeks on the supplement.
And so the craze began.
How is Svetol or GCA different?
Svetol or GCA are the names for the patented green coffee bean extract developed by Naturex, a maker of ingredients for cosmetics, nutraceuticals, pharmaceuticals, foods and beverages based in Avignon, France. Produced from the Robusta variety of coffee beans, this extract provides 50 to 55 percent polyphenols and 45 to 50 percent chlorogenic acid per serving, according to Naturex. The company follows a traditional extraction process to keep the nutrient profile of the beans intact while removing caffeine.
This extract has no reported side effects and is made with only non-GMO coffee beans and is free of allergens, pesticides, heavy metals and contaminants like aflatoxins or ochratoxin A. The chlorogenic acid in this particular extract was found to be highly bioavailable in humans, according to a 2008 study published in the Journal of Nutrition. This means they're well absorbed from the intestines, which could make them more effective.
We weren't able to find any research to indicate this patented extract was more effective in promoting weight loss than others, but increased bioavailability is known to improve the usefulness of the extract by the body and its effects.
