Chlorogenic acid is a natural compound found in raw green coffee beans but when the coffee beans are roasted, the chlorogenic acid is mostly destroyed. So, the potential healthy benefits from drinking regular coffee (i.e. coffee brewed from roasted coffee bean) would likely be significantly less than if taking a green coffee chlorogenic acid nutritional supplement.
That said, there has been a lot of recent research suggesting a number of health benefits from traditional roasted coffee, even though brewed coffee from roasted coffee beans has substantially less chlorogenic acid than most raw green coffee bean supplements.
Raw coffee beans are the most abundant natural plant source of chlorogenic acid.
Green coffee bean extract is generally consumed as a supplement since drinking liquid coffee made from unroasted coffee beans would have a bitter unpleasant taste, and would not provide the desired dosage of chlorogenic acid.
Some recent research has suggested chlorogenic acid may improve retinal health. Other research suggests that chlorogenic acid inhibits the release of glucose into the blood stream. Japanese researchers did a study in 2005 using a placebo for some participants and green coffee bean extract on the others, in a test of the potential effects of the substance on people with mild hypertension. The result was lower blood pressure and no negative side effects.
Larger, peer-reviewed research is needed.
