How to Choose a Green Coffee Bean Extract

By Michael A. Smith, MD

If 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 Absorption

To 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.
Now in order for you to achieve similar results, you will need to take the same green coffee extract in terms of dosing and standardization of chlorogenic acid.

How to Pick the Right Green Coffee Bean Extract

And 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!

Anonymous - We can’t suggest certain brands. However, consider products that are standardized to contain chlorogenic acid- the active ingredient in green coffee. Supportive dosages range between 200-600 mg daily. Hope this helps!

I have tried many diet pills such as duramine, prescopodine, ultra detox but none of them has helped. I am fed up and quite annoyed but still cant stop looking for weight loss pills and programs. My schedule is very tiet and have no time for gym at all. I weigh 120 kgs and hieght is 5 feet 9 inches. Heard about this green coffee bean so got bit excited that it might help. But does it really helps? What brand do you recommend and what should be dosage of chlorogenic acid in it and how to take it? This is my last hope, please help with the answers. thanks

Anonymous - Research shows that green coffe supports healthy weight management. Here's a link to a study in case you're interested: http://ow.ly/gBu8t

Consider products that are standardized to contain chlorogenic acid- the active ingredient in green coffee. Supportive dosages range between 200-600 mg daily and should be taken before your heaviest meals. In regard to a certain brand, we can't make a suggestion in that department, but we're sure you won't have to look far to find a good one. ;-)

I take Armour for under active thyroid and metformin. Is it safe for me to take GC50 Green Coffee? And will it work?

LifeExtension said...

Anonymous - Since you're taking a blood sugar lowering medication (Metformin), you may wan to be extra cautious in taking green coffee extract, since there could be an increased risk for hypoglycemia (low blood sugar levels). Please work with your doctor and make sure to take supplements at least 2 hours apart from any medication.

In regard to the green coffee extract, the research shows that it has helped people lose weight, but we can't guarantee 100% that it will work for you, since everyone reacts differently to supplements.

We hope this helps!

will this work, green coffee bean extract 400mg caps with 45% xc
45% chlorogenic Acid? anonomys?

LifeExtension said...

Terri Loten - It may work, the only way to know is to try! The research showing a weight loss benefit used a 50% chlorogenic acid extract.

Anonymous said...

I also have a bottle that says 45%chlorogenic acid but it also says 200mg it says its made wit svetole is this ok an will it work just as good plz tell me??

LifeExtension said...

Anonymous - We can't know for sure if a certain brand of green coffee extract will work. A minimum of 100 mg of chlorogenic acid has been shown to support weight loss. The product you're taking contains 90 mg.

Paul Rodriguez said...

The bottle I have now list this:
Serving size: 1 capsule

Green coffee bean extract (Coffea arabica) 400mg

(Standardized to contain 45% chlorogenic Acids, 180mg)

Why two different amounts of MG's listed? What number do I pay attention to? Am I wasting my money on 180mg because im paying for a false 400mg?

Thank you

LifeExtension said...

Paul Rodriguez - The active ingredient in the green coffee extract which supports weight loss is chlorogenic acid. Per capsule you are getting 400 mg of green coffee extract. Within the 400 mg, there is 180 mg of chlorogenic acid. Does that make sense?

Paul Rodriguez said...

Now it makes sense. Thank you. Now although the one I have is 45% chlorogenic acid and not the 50% BUT it is over the 100mg of chlorogenic acid used in the weight loss study. So it seems my product should be more than adequate.

LifeExtension said...

Paul Rodriguez - OK good!

Anonymous said...

hi, do you have any clue about the remaining 50% of coffee extract, what does it contain? I mean all the substances in coffee extract which are not chlorogenic acid. Regards, Kasia

Life Extension said...

Anonymous - It depends on the brand, but in it's natural state green coffee contains ingredients such as alkaloids, proteins, free amino acids, and carbohydrates.

Anonymous said...

Mine say each capsule contains 7,000mg of green coffee bean with 180mg of chlorogenic acids but you take two a day? Because of the double dose is that enough?

Life Extension said...

Anonymous - You may want to follow the dosing instructions of your product. Unfortunately, we can't provide suggestions for another company's products.
