Green coffee bean extract is simply coffee bean that has not yet been roasted. In order to commercialize regular coffee, it first needs to be roasted. The roasting process gives coffee its wonderful aroma; however during this same roasting process, it loses an important element: chlorogenic acid. The chlorogenic acid in green coffee has been proven to combat diabetes, heart disease, and weight gain, among other health issues. So the non-roasted coffee bean (or green coffee bean extract), contains a significantly high amount of chlorogenic acid. Clorogenic acid is the ingredient within coffee beans that has been suggested to help lose weight. A month’s supply of this supplement costs between $20 and $30.
The popularity of green coffee bean extract reached its peak after Dr. Oz mentioned it on his show sometime in 2012. On the show, Dr Oz referred to it as “the green coffee bean extract that burns fat”.
Is the Green Coffee Bean Extract Backed by Research?
The answer to that question is Yes and no.
YES: When you type “green coffee bean extract” into Google, you’ll see that most of the articles point to a study by Dr. Joe Vinson, which was published in the journal Diabetes, Metabolic Syndrome and obesity. 8 men and 8 women participated in the study and after 22 weeks (roughly 5 months), it was determined that the participants lost more than 17 pounds on average. Dr. Joe Vinson, who was a professor of Chemistry at the University of Scranton, Pennsylvania (and lead author of this particular study), noted that the green coffee bean extract has a significant weight loss associated with it.
NO: Not everyone is in agreement with this study. Some obesity experts point out that the study has several flaws, mainly the fact that the sample size was so small, combined with the fact that participants still lost weight during the placebo phase of the study.
In addition, they claim that Dr. Joe Vinson was financially incentivized to conduct the study, which represents in itself a major conflict of interest.
Are all Brands of Green Coffee Bean Extract the Same?
As you may have guessed, not all brands are equal. 3 important things make a brand of green coffee bean extract legitimate:
- It should contain at least 45% chlorogenic acid
- It should contain Green Coffee Anti-oxidant (GCA)
- It should have at least “400 mg Strength”
Dr Oz advised that people add green coffee bean extract to their weight loss regimen. As mentioned above, it’s recommended that you use a capsule that contains a minimum of 45% chlorogenic acid. The recommended dosage is 400 mg taken 3 times daily, approximately 30 minutes before your meal.
There’s no adverse side effects noted in adults, however pregnant women and people under the age of 18 should stay away from it. Same goes for those who are allergic to caffeine.
