When coffee beans are roasted, something is lost: chlorogenic acid. This remarkable compound appears to block the absorption of sugar and fats by inhibiting several key enzymes. That’s crucial, because your body can only turn calories into fat if you absorb them. Each 500 mg vegicap of Green Coffee Extract contains 250 mg of chlorogenic acid per vegicap. Double-blind, placebo-controlled human studies, lasting 4 to 12 weeks, have shown that green coffee bean extract promotes an agerage weight loss of 5.5 lbs. To maximize weight loss, combine Green Coffee Extract by Vitagen with a healthy diet and regular exercise.
