How does green coffee bean extract work… what is the mechanism?
Green coffee bean extract contains caffeine.Several studies have shown that caffeine can stimulate metabolism up to 3-11% However, the main active ingredient is supposed to be chlorogenic acid.Some human studies suggest that it can reduce the absorption of carbohydrates from the digestive tract, which lowers blood sugar and insulin spikes If this is true, then take the green coffee bean extract would be like eating a slightly lower diet in carbohydrates.Other studies have shown that chlorogenic acid can reduce body weight, reduce fat intake, reduce stored fat in the liver, and improve the function of adiponectin, a fat-burning hormone.Chlorogenic acid has also been shown to significantly improve cholesterol and triglyceride levels in rats. These are important risk factors for heart disease.
