By Michael A. Smith, MDIf you haven’t heard, green coffee bean extract is the latest weight loss supplement that’s been getting lots of attention over the past few weeks. It’s becoming clear from recent research that freshly picked coffee beans actually contain a whole lot of beneficial compounds with massively appealing benefits.
Now, since we’re an extraction-based company, naturally we asked, “What are those beneficial compounds?” The answer is antioxidants, in particular one that’s called chlorogenic acid.
But we didn’t stop there. The next question we asked is this: How much chlorogenic acid is needed to optimize the potential benefits, including reduced blood sugar levels and weight loss?
The answer to that question was found in the clinical studies. And that’s exactly what extraction-based companies like Life Extension® do — we look at the research. What amount or standardization of the extract was used to obtain the desired benefit? Answering this question is taking an evidenced-based approach to supplementation … and what we’re all about.
Well, let’s take a look at the research showing the weight loss benefits of chlorogenic acid. In this study, a specific amount of chlorogenic acid was used to block calorie absorption. Knowing this exact amount is probably a good idea if you’re planning on trying this yourself to lose weight.
Chlorogenic Acid from Green Coffee Inhibits Calorie AbsorptionTo investigate the weight-reducing effect that had been shown in previous brewed coffee studies, scientists turned to compounds extracted directly from green coffee beans. The green coffee beans contain higher amounts of chlorogenic acid and other polyphenol compounds that are substantially lost during the roasting process that turns them brown.
Here’s the breakdown of the study. This was a 12-week, placebo-controlled clinical study testing the effectiveness of green coffee extract in overweight and obese people:1
- Thirty overweight or obese human volunteers took either the extract or a placebo, dissolved in instant coffee.
- The extract produced an average 5.4 pound weight loss. This was paralleled by a decrease in glucose absorption and an increase in glucose utilization.
- The researchers reported that the lower availability of glucose that results from these effects would cause the body to increase the metabolism of fat reserves, which would eventually decrease body fat and mass.
How to Pick the Right Green Coffee Bean ExtractAnd this is where you can trust Life Extension. We are more than just an extraction-based company — we also formulate our products using the dosing and standardizations used in clinical studies. This is known as “evidenced-based supplementation.”
The study showcased above and additional studies using green coffee extracts standardized the chlorogenic acid to 50%. This means that in a green coffee extract of 200 mg, you’ll get 100 mg of chlorogenic acid — the dosing used in the weight loss study.
So achieving 11 pounds of weight loss in 12 weeks requires a minimum of 100 mg of chlorogenic acid. Be careful. Other companies are jumping in on the “chlorogenic acid bandwagon.” You’ll start to see it everywhere. But ask yourself this: Is the green coffee extract you’re about to purchase standardized to 50% chlorogenic acid? If not, don’t buy it.
How do you know if your coffee extract is standardized correctly? Look on the label. Here’s an example of one. First, locate the green coffee extract. Now look within the parentheses to find the standardization of chlorogenic acid:
Now, of course your other option is to just give our version of these products a look. We assure you that our labels will not disappoint!
