SD Pharmaceuticals' GREEN COFFEE BEAN GCB delivers 350 mg of top-quality Green Coffee Bean powder in every capsule! In addition, SD Pharmaceuticals' GREEN COFFEE BEAN GCB delivers 50% chlorogenic acid content to support weight loss! Green coffee beans are coffee beans that have not yet been roasted. The roasting of coffee beans reduces the chlorogenic acid levels. That's why green coffee beans have a higher level of chlorogenic acid compared to regular, roasted coffee beans. The chlorogenic acid component in green coffee is what's thought to be responsible for several of its pharmacological effects, including fat-loss support. Research suggests that it's the chlorogenic acid constituent of green coffee bean that can support fat loss. Chlorogenic acid from green coffee bean has been shown to have modulating effects on glucose metabolism and it has also been shown to help inhibit fat accumulation and reduce weight in animal and humans studies.
