Green coffee beans, or raw coffee beans, are coffee beans that are not roasted. Green coffee bean extract is a popular weight loss supplement.

Some research also suggests that green coffee bean extract could have health benefits, such as improving blood pressure and cholesterol levels. This belief stems from the antioxidant properties and other pharmacologically active compounds in the unroasted beans.

Green coffee extract contains chlorogenic acids, which are a group of antioxidant compounds that scientists believe may be responsible for its health effects.
