Currently one of the world’s most popular weight-loss supplements, green coffee bean extract is being seen as the new magical solution for instant weight loss. As the name suggests, the supplement is prepared from green coffee beans and was put under spotlight by famous American TV doctor Dr Oz.

What Are Green Coffee Beans?

As coffee beans are naturally green, green coffee beans are nothing but coffee beans that haven’t been roasted. They are rich in antioxidants and active compounds such as caffeine and chlorogenic acid.

While studies show that caffeine can boost metabolism by three to 11 percent, chlorogenic acid is believed to be the active substance that produces the weight loss effects.[1,2,3] However, most of the chlorogenic acid is removed when the coffee beans are roasted to get a brown color.[4]

Health Benefits Of Green Coffee Bean Extract

Green coffee beans are more bitter in taste than roasted beans and are easier to consume as an extract. And while everyone associates them with weight loss, did you know that green coffee bean extract also helps in managing diabetes?

1) Reduces Risk Of Heart Disease

Chlorogenic acid in green coffee beans effectively reduces cholesterol and triglyceride levels, both risk factors for heart disease.[5] It is also an excellent antioxidant.[6]

2) Helps Manage Diabetes

Clinical studies suggest that chlorogenic acid also reduces the absorption of carbohydrates from the digestive tract that lowers blood sugar and controls spikes in insulin levels.[7,8] Animal studies suggest that it can even reduce glucose absorption.[9]

3) Reduces High Blood Pressure

Animal and clinical studies show that doses ranging from 140mg to 720mg of green coffee bean extract per day have been effective in lowering blood pressure.[10,11]

4) Weight Loss

Chlorogenic acid can reduce fat absorbed from the diet, reduce the fat stored in the liver and improve the function of the fat-burning hormone adiponectin, thereby reducing body weight.[12,13] A clinical study found that people who consumed green coffee bean extract lost more weight in comparison to the group that had regular instant coffee.[14]
