Green Coffee
Overview
"Green coffee" beans are coffee seeds (beans) of Coffea fruits that have not yet been roasted. The roasting process of coffee beans reduces amounts of the chemical chlorogenic acid. Therefore, green coffee beans have a higher level of chlorogenic acid compared to regular, roasted coffee beans. Chlorogenic acid in green coffee is thought to have health benefits.
Green coffee became popular for weight loss after it was mentioned on the Dr. Oz show in 2012. The Dr. Oz show referred to it as "The green coffee bean that burns fat fast" and claims that no exercise or diet is needed.
People take green coffee by mouth for obesity, diabetes, high blood pressure, Alzheimer's disease, and bacterial infections.

How Does It Work?
Green coffee beans are coffee beans that have not yet been roasted. These coffee beans contain a higher amount of the chemical chlorogenic acid. This chemical is thought to have health benefits. For high blood pressure it might affect blood vessels so that blood pressure is reduced.
For weight loss, chlorogenic acid in green coffee is thought to affect how the body handles blood sugar and metabolism.
Uses
- High blood pressure. Early research suggests that taking green coffee extracts containing 50 mg to 140 mg of chlorogenic acids daily for 4 weeks to 12 weeks can reduce blood pressure in Japanese adults with mild and untreated high blood pressure. Systolic blood pressure (the top number) appears to be reduced by 5 mmHg to 10 mmHg. Diastolic blood pressure (the bottom number) appears to be reduced by 3 mmHg to 7 mmHg.
- Obesity. Early research shows that adults with obesity who take a specific green coffee extract (Svetol, Naturex) five times daily for 8 weeks to 12 weeks, either alone or together with the regular coffee product Coffee Slender (Med-Eq Ltd., Tonsberg, Norway), lose an average of 2.5 to 3.7 kg more weight than people taking a placebo or regular coffee by itself.
- Alzheimer's disease.
- Type 2 diabetes.
- Other conditions.
Recommended Dosing
The appropriate dose of green coffee depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for green coffee (in children/in adults). Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
