Green Coffee Bean Reviews


After being featured as a weight loss supplement on a popular television show, green coffee bean has been the subject of many research studies.

Using green coffee bean extract for weight loss is growing in popularity, but there are facts that you need to be aware of before choosing it as an option.

What is Green Coffee Bean?

Green coffee bean extract is made from unroasted coffee beans. The beans contain a significant amount of chlorogenic acids have been shown to have antioxidant properties.

Antioxidants can lower blood pressure, build the immune system and have been shown to aid in weight loss.

When coffee beans are roasted, they lose some of the chlorogenic acids, which is why drinking brewed coffee does not have the same effect as using green coffee beans. [1]

Use of Green Coffee Bean

Research has shown that coffee existed over 1,000 years ago and were commonly used in Africa.

Arabica were popular in South Sudan and Ethiopia while robusta was popular in West Africa.

At that time, beans were not roasted, but were blended with fat and seeds to make the earliest version of energy bars.

The ancient civilizations boiled the leaves to create green coffee bean drink that they used as an added energy boost. Other cultures used green coffee bean herbs to make teas and other substances used for medicinal purposes.

It wasn’t until African slaves brought the beans to Asia in the 1400s that roasting began, creating the liquid today known as coffee.

As a result, the consumption of green coffee beans dropped significantly as people preferred the roasted beans.

Then, in 2012, Dr. Mehmet Oz aired a segment on his popular afternoon television series, “The Dr. Oz Show,” which featured a study that found the use of green coffee bean could improve weight loss results.

Following the show, sales of green coffee beans rose significantly.

Green Coffee Bean Ingredients

There are many different ways to consume green coffee beans. You can purchase green coffee bean powder which can be mixed into smoothies or other foods.

You can also consume green coffee bean chews or capsules. It is also possible to use green coffee bean drops or oils. When choosing a green coffee bean supplement, be sure to read the label carefully.

You want to choose a product that does not contain artificial or synthetic chemicals. Choose green coffee bean pills or powder that has a high level of chlorogenic acid.

Experts recommend levels of 45 percent or higher for maximum benefit. [2]

Green Coffee Bean Nutrition Facts

When it comes to green coffee bean nutrition facts, one green coffee bean extract pill has zero calories, zero fat and zero cholesterol.

It also contains no sodium, potassium, carbs or protein. Therefore, adding green coffee bean extract to your diet won’t increase calorie, fat or carbohydrate intake.

Green coffee bean powder also adds no calories or other nutritional value to your diet. It is important to note that green coffee bean oil, powder and supplements, as well as green coffee bean drops do contain caffeine, usually around 40 mg which is the equivalent of half a cup of brewed coffee. [3]

What Does Green Coffee Bean Do?

There is extensive research that indicates the benefits of chlorogenic acid on weight loss, blood pressure and how the body regulates blood sugar.

When coffee beans are roasted, they lose much of the chlorogenic acid which is why green coffee beans are a better option.

However, the bitter taste of green coffee beans means they are not suitable for brewing without being roasted.

For this reason, many people choose green coffee bean pills or other supplement versions to get green coffee bean for weight loss benefits.

Chlorogenic acid is also found in prunes and is thought to be the compound that causes the laxative effect, which is also a side effect found in coffee.

Scientists believe that chlorogenic acid helps regulate bile as it flows from your liver and helps prevent side effects from bile build up in the liver.

It has been shown to improve liver health and may prevent against some types of liver disease, such as cirrhosis and cancer. [4]

Green Coffee Bean and Weight Loss

On the Dr. Oz Show, one of the biggest green coffee bean benefits was its effect on weight loss.

On the show, Dr. Oz touted one study that reported significant green coffee been extract benefits in relation to weight loss, but since the show aired, experts have downplayed the study.

In a 2011 report published in Complementary Medicine, a publication of the Peninsula Medical School at the University of Exeter, researchers found that several animal studies that found a change in glucose concentration in rats, indicating that green coffee bean capsules and oils may provide the same benefits in humans. [5]

In this study, a review of several clinical trials found that there may be a connection between the intake of green coffee bean extract and weight loss, but because the samples in those studies had been small, more research needed to be conducted.

Another report in the Journal of International Medical Research found that coffee enriched with chlorogenic acid appeared to have an effect on the absorption and utilization of glucose.

This indicates that the use of a green coffee bean dietary supplement may result in a reduced body mass and could result in a reduction of body fat when used consistently.

Green Coffee Bean and Gallstones

In addition to weight loss, researchers are finding that the supplements may also reduce the risk of gallstones, adding one more green coffee bean extract benefits.

Bile is produced in the liver which is then emptied into the gallbladder. Inside the gallbladder, bile is either stored temporarily or emptied into the small intestine.

Impairments of the flow of bile in the gallbladder can result in the development of gallstones.

In a study conducted at the Institute for Traditional Medicine in Portland, Oregon, Dr. Subhuti Dharmananda found that increased intake of chlorogenic acid improved the flow of bile and reduced the risk of stagnation in the gallbladder. [6]

There are those who believe that a green coffee bean detox helps cleanse the liver and gallbladder as well.

Green Coffee Bean and Blood Pressure

Several research studies have found that chlorogenic acid reduces blood pressure in hypertensive rats and humans.

Clinical trials found that substances like a green coffee bean dietary supplement can reduce blood pressure and pulse rate.

In one study, it was determined that green coffee bean diet supplements did reduce blood pressure and had no side effects.

However, the study also found that there was no difference in body mass index or pulse rate.

Although more research is necessary, current reports indicate that taking 50 mg to 140 mg of green coffee bean supplements for between 4 and 12 weeks may reduce systolic blood pressure by 5 mmHg to 10 mmHg and diastolic blood pressure from 3 mmHg to 7 mmHg. [7]

Green Coffee Bean and Diabetes

A study conducted by the University of Scranton found that patients in a clinical trial who consumed green coffee bean extract for weight loss also saw a reduction in blood glucose levels. [8]

Patients were given green coffee bean capsules over a period of 22 weeks at dosages between 100 mg and 400 mg. Those who took the higher levels of green coffee bean supplements saw the highest drop in blood glucose.

In addition, the participants saw a 10 percent reduction in weight.

The study was a small sampling and more research is necessary to determine how green coffee bean extract may benefit those diagnosed with Type 2 diabetes.

Green Coffee Bean and Energy

Green coffee beans have no coffee flavor but contain the same amount of caffeine as roasted beans which is why many people use green coffee bean for energy.

The extraction process used while roasting the beans is what increases the amount of caffeine in the beans.

Most supplements are made by soaking the bean and using the concentrate produced to create green coffee bean oil, powder or tablets. It is also possible to drink green coffee bean coffee, although it will not taste like traditional coffee.

Although green coffee beans have a lower caffeine level than roasted coffee, it can actually make you feel more energetic as the caffeine boost is more natural than what comes with roasted coffee beans. [9]


Does Green Coffee Bean Work?

Although most of the studies are on small samples, there are numerous studies that indicate the right green coffee bean dosage can aid in weight loss, lowering blood pressure and improving blood glucose levels.

In some cases, users of green coffee bean lose belly fat at a higher rate than those who do not, although those reports have not been substantiated by scientific study.

In one study, 30 overweight individuals consumed regular instant coffee while another consumed regular coffee combined with green coffee bean coffee.

Both groups were instructed not to change their diet. At the end of 12 weeks, the group drinking green coffee bean coffee lost almost 12 pounds while the group drinking regular coffee lost less than four pounds. [10]

In addition, the green coffee bean drinkers lowered their body fat by almost four percent while the regular coffee drinkers saw a body fat drop of less than one percent.

Scientists warn that some of the studies conducted were paid for by companies that manufacture green coffee bean supplements and products.

More research needs to be conducted to determine conclusively that green coffee beans promote weight loss or provide any other medical benefits.
