Green coffee bean extract is a supplement made from unroasted coffee beans that contains chlorogenic acid and caffeine:

Blood pressure

Green coffee may help lower blood pressure in some people. The chlorogenic acid in green coffee may affect blood vessels.

Blood sugar

Green coffee may help improve blood sugar regulation. The chlorogenic acid in green coffee may lower blood sugar levels and reduce insulin spikes.

Weight loss

Some research suggests that green coffee may help with weight loss by lowering blood sugar and blocking fat buildup. However, many experts agree that there is no substitute for maintaining a healthy diet and getting regular exercise.

Anti-inflammatory

The chlorogenic acid in green coffee is a natural antioxidant that may help tame inflammation.

Anti-aging

Green coffee beans may help slow the overall effects of aging both mentally and physically. The caffeine and chlorogenic acid in green coffee may help with sun damage, wrinkles, and dry, rough skin.

Green coffee contains less caffeine than regular coffee. However, the quality and active ingredients in supplements may vary widely from maker to maker. You should ask your doctor for advice.
