Green coffee bean extract has been one of the hottest weight loss supplements since it can boost your metabolism and help you burn more fat.

Here’s what you need to know about the best green coffee bean extracts on the market.

1. NatureWise Green Coffee Bean Extract 800

As king of the sales hill with thousands of Amazon reviews, it’s hard to ignore NatureWise. What are they doing right? The supplement delivers 800 mg of green coffee bean extract, which is in the range of typical doses given in research studies.

More importantly, NatureWise uses an independent third-party lab to verify the purity and dosage of its supplement. This can’t be overemphasized, given the problems that have plagued the supplement industry when it comes to dosage and purity. The capsules come in a vegetable cellulose capsule and include only rice bran as a filler. With a guarantee of purity and a solid dosage, it’s hard to find fault with NatureWise.

2. Sport Research SVETOL Green Coffee Bean Extract

Finally, a company that takes a different tack with green coffee bean extract. This supplement comes in a gelatin capsule (sorry, vegans!) and provides a detailed breakdown of the chemical constituents of the 400 mg green coffee bean extract dose, listing the percentage contents of each active ingredient. 

The capsule also provides 800 mg of coconut oil, probably to jump-start your fat metabolism. The MCT oils in coconut oil are a great supplement in their own right; it’s just a matter of whether it’s enough to substantially change your metabolism is up in the air. Though it is more expensive, likely on account of the more scientific precision applied to the ingredients, it’s a very solid choice.

3. BulkSupplements Pure Green Coffee Bean Powder

For the real do-it-yourselfer, you can make and mix up your own green coffee bean extract from BulkSupplements’ bag of loose powder. This is not for everyone, though: given that green coffee bean extract is a potentially potent metabolism booster, you need a scale with milligram precision to measure out accurate doses. 

BulkSupplements makes fantastic products; the downside is always the challenges of measuring doses yourself. In the case of green coffee bean extract, eyeballing it with a scoop just isn’t an option. If you’ve got the right scale, go for it; otherwise, let the pros do the work.

4. Greenlabel Premium Green Coffee Bean Extract

Greenlabel toes the same line as most other green coffee bean extract manufacturers, delivering 800 mg of the supplement per capsule via a cellulose and magnesium stearate vegetarian capsule. 

The main advantage of Greenlabel is its cost-effectiveness, especially when you buy multiple packages at once. It’s one of the cheapest when bought in bulk, so if you know you’ll be taking it for a long time, it’s a good choice. It’s well-reviewed and has a lifetime money-back guarantee as added perks.

5. aSquared Nutrition Green Coffee Bean Extract

aSquared Nutritin’s green coffee bean product tries to capitalize on your pragmatic consumer sensibilities. In terms of ingredients, it’s nothing special, but it is made in the United States, so you can expect higher manufacturing quality. Unfortunately, aSquared hasn’t had their purity or dosage verified by an external lab, so you are still going by the honesty policy when it comes to the quality of the product.

6. NutraChamps Green Coffee Bean Extract

Yet another green coffee bean supplement in the “good but not great” category. NutraChamps offers the boilerplate arrangement: 800 mg of green coffee bean extract per capsule, and a vegan-friendly cellulose and stearate pill to contain it. 

The label, as usual, boasts of highest-quality ingredients and good purity, but there’s no independent verification of these claims. It’s made in the US and distributed by NutraChamps, which is based in Canada, but beyond that, there’s nothing very notable about this green coffee bean extract supplement.

7. DietWorks Green Coffee Bean Extract

Though DietWorks provides a pretty standard green coffee bean extract, it falls short in a few key areas. The capsules seem unneccessarily bloated with extra ingredients and fillers, and the green coffee antioxidant (GCA) content is only standardized to 45% instead of the typical 50%. 

While five percent is not a big deal, it’s pennies on the dollar to get a supplement that’s got more bang for your buck. It is fairly popular among the low-cost crowd, though.

8. Nature Berg Green Coffee Bean Extract

Click here for the lowest price on Amazon

Packaged in a vegetarian cellulose and stearate capsule with an 800 mg dosage, Nature Beg provides a solid green coffee bean extract supplement that includes green coffee antioxidants, or GCAs, as well. It’s a coffee-based product, so of course there is some caffeine in it; the label says each pill contains 20 mg of caffeine. 

Kudos to Nature Berg for actually disclosing the caffeine content of their supplement; not all manufacturers do this. The biggest drawback might be the lack of popularity: with a general lack of reviews, it’s hard to take Nature Berg too seriously.

9. Health Plus Prime Green Coffee Bean

Though this is one of the cheapest green coffee bean extract supplements you can buy, it seems to have a bad reputation recently among online reviewers. The label characteristics are mostly unremarkable except for one seemingly minor detail: the recommended dosage is two capsules, totaling 1600 mg of green coffee bean extract, instead of the typical one capsule of 800. 

This may account for the poor reviews; users complain of feeling jittery and an inconsistency in the coloring of the capsules: not a great sign! Others are plenty happy, though, so if you want to roll the dice on a cheaper green coffee bean extract, it’s an option.

10. Crystal Clear Solutions Extra Strength Green Coffee Bean Extract

One of the issues with green coffee bean extract supplements is that a lot of lesser-known manufacturers are trying to cash in on the supplement’s popularity by copying the formulation of the big brands. Now, there’s no way to know who’s legit and who’s not–and make no mistake, there are plenty of high-quality small batch supplement operations, but in this case, it’s hard to get an idea of whether Crystal Clear Solutions is a reputable manufacturer. 

Online reviews are mixed, and the company doesn’t have a huge selection of popular supplements, so it may be better to steer clear and let other people be the guinea pigs.

Part 2: Green coffee bean extract overview

Chlorogenic acid is the active ingredient in green coffee bean extract thought to assist in weight loss. The supplement is among the most popular weight loss aids in today’s market.

According to a recent Gallup poll, more than half of Americans say they want to lose weight. (1)

No big surprise there, since nearly two thirds of Americans classify as overweight or obese, and carrying extra pounds is considered a leading public health problem in our country. (2)

You may well be one of those contributing to the annual outlay of $60 billion on weight loss products (3), which includes gym memberships, exercise equipment, supplements, and specialty foods.

We all want to get something for the money we spend, especially when it comes to weight loss aids that claim to help drop numbers on the scale.

Let’s see if green coffee bean extract merits a slot in your budget.

Benefits

Human studies confirm caffeine boosts metabolism, causing the body to burn more calories, so that’s a good place to start if you enjoy coffee. (4)

Incorporating green coffee bean extract in your diet plan could boost the effectiveness of caffeine while adding other health benefits.

When coffee beans are roasted, the chlorogenic acid is lost (5, 6), whereas raw, green coffee beans are rich in the stuff.

Chlorogenic acid takes coffee’s effect on metabolism to another level by inhibiting the absorption of carbohydrates in the digestive system. This mutes the body’s insulin response, which results in keeping blood sugar levels lower. (7)

Here’s how mice and rats responded to chlorogenic acid in lab tests: (8, 9)

  • Body weight reduction
  • Less absorption of dietary fat
  • Less fat stored in the liver
  • Raised levels of adiponectin, the fat-burning hormone
  • Reduced absorption of glucose

There’s no guarantee the substance has the same effect on humans, but other health benefits noted in animal studies included lower triglyceride and cholesterol levels (10), both of which are risk factors in developing cardiovascular disease.

A small randomized, controlled trial working with 30 overweight participants during a 12-week period showed promising results for supplements containing green coffee bean extract. (11)

One group drank coffee with 200 mg of green coffee bean extract added, while the other group drank regular coffee. No one was asked to make any changes in diet or exercise.

Those taking the extract dropped nearly 12 pounds, while the control group was down 3.7 pounds over the three months.

The control group experienced a reduction in body fat percentage of less than 1%, while the others measured a significant change at 3.6%.

A longer study of 22 weeks involved 16 overweight participants. In this group, two separate dosage levels of green coffee bean extract (1050 mg and 700 mg) were used, along with placebos. Subjects took a two-week break between changing dosage or, in some cases, taking a placebo. (12)

The largest amounts of weight loss occurred during the time periods when participants were taking green coffee bean extract.

Average reduction was just over 8 pounds, and body mass index measurements dropped enough to shift some participants from pre-obesity to normal ranges. Decreases in body fat averaged close to 5%.

Other studies have been conducted by companies who profit from the sales of green coffee bean extract, a common practice that should inspire caution when reviewing the results since the methodology isn’t as rigorous or standardized. (13, 14)

While longer studies with more participants will determine if green coffee bean extract can be a significant boon to anyone looking to drop extra pounds, chlorogenic acid may be in the running for improving health in other ways.

The substance possesses strong antioxidant properties, and may have positive effects on blood vessel health. (15)

Subjects using 140 to 720 mgs of green coffee bean extract in one study had lower blood pressure measurements, an important marker for heart health. (16, 17)

The muting effect of the chlorogenic acid on glucose absorption could be helpful in managing symptoms of diabetes.

Side Effects

While the safety profile of green coffee bean extract is generally good, respiratory reactions may occur in people with allergies. (18) If you know you’re sensitive to coffee, consider skipping the risk of using the extract.

When caffeine is consumed in large amounts, it can cause side effects like rapid heartbeat, nervousness, insomnia and anxiety. Pregnant women and children shouldn’t use caffeine, including green coffee bean extract. (19)

Chlorogenic acid can exert a laxative effect in some individuals, causing diarrhea. Dosages of chlorogenic acid usually run between 120 and 300 mg, which translates to somewhere between 240 and 3000 mg of green coffee bean extract.

Recap

The idea that weight loss success can be achieved with a supplement like green coffee bean extract is appealing, especially for those who haven’t reached their goals through dieting alone.

Since one of the strengths of chlorogenic acid is to reduce the effect of carbohydrates on blood sugar, many people might see this as a way to support weight loss efforts while still being able to eat refined carbohydrates and other foods high in sugar content, all of which spike insulin levels and contribute to fat storage.

While it’s true these are “fun” foods to consume, controlling the damages inflicted by ingesting them isn’t the most effective approach.

Making changes in lifestyle is the only proven method for maintaining normal weight and improving overall health. For most people, this means cutting back or eliminating the foods that cause blood sugar problems and weight gain, replacing them with whole, nutritious choices, as well as engaging in regular exercise.

If you decide to give green coffee bean extract a try, a great selection of capsules in various strengths is available; like many supplements, the cost will often run around a dollar a day for recommended dosages.

Instructions usually say to take one serving about half an hour before each of three meals daily. Use caution and start with a single dose daily if you’re the sensitive sort.

Summary: Green coffee bean extract might be helpful for short term weight loss, but over the long term, taking any supplement in hopes of keeping weight off isn’t the best idea.
