Green coffee extract is obtained in its natural form which retains beneficial phytonutrients. One such phytonutrients is chlorogenic acid, which is depleted during the roasting process. Genesis PURETM Green Coffee Bean contains 50% chlorogenic acid, offering beneficial polyphenol antioxidants. This amount is comparable to some products used in weight management research. Some studies show that the chlorogenic acid in green coffee beans affects how the body handles blood sugar and metabolism.
