Green Coffee is high in chlorogenic and caffeic acid, the two primary compounds responsible for the activity of green coffee. Leading US Physician, author and talk show host, Dr. Oz, recommends chlorogenic acid for aiding in weight loss. Caffeic acid is well known for its anti-oxidant power. Green coffee extract (GCA) is derived from raw, unroasted green coffee beans which are naturally low in caffeine.
