Other than the obvious difference in color between roasted coffee beans and green beans, is it possible that green coffee bean extract benefits provide unique perks to health and wellness than any other kind of coffee bean?
A few interesting facts we’ll discuss are beneficial in choosing the best brands available at numerous drug drugstores or health food markets in your area.
The extract gained popularity after its mention on the Dr. Oz television show in 2012.
On the television show, Dr. Oz claimed that the beans burn fat fast and don’t necessarily require a person to diet or exercise to see results.

What is Green Coffee Bean Extract?
Many consumers are surprised to discover that it is not really a ‘bean’ plucked off a tree in that state.
Actually, the beans are more commonly known as berries, and are plucked off of coffee plants grown in over 70 countries around the world.
They come from the Coffea plant, grown mainly in regions around the equator including South America, India, Africa, and Southeast Asia.
The beans are picked when they’re ripe, and then processed and dried.
One of the earliest historical mentions of the popular beverage’s origin refers to Yemen and date back to the mid-1400s.
The first serious cultivation originated in southern Arabia. Over the centuries, coffee has become one of the most widely exported commodities in the world.
Green Coffee Bean Extract Benefits & Side Effects
During the roasting process, a component of green coffee beans is literally cooked out.
That ingredient found inside is known as chlorogenic acid or CGA. Chlorogenic acid is believed to enhance metabolism, or the rate at which the body consumes or utilizes energy for fuel.
During the roasting process, chlorogenic acid is destroyed.
It has also gained a reputation in promoting weight loss, of course when coupled with a well-balanced diet and exercise.
A number of studies have been conducted and results show that consumption has the ability to enhance glucose tolerance and lower cholesterol levels in the body.
Another benefit, at least for many coffee drinkers, is that green beans contain less caffeine than roasted beans do.
Green coffee bean extract capsules encourage the body to utilize enzymes that are designed to convert unused energy (glucose) into deposits of fat in the body for later use.
However, chlorogenic acid blocks those enzymes from doing that, effectively preventing unused energy from forming into fat. T
he extract is also believed to help the body break down stored fat cells while at the same time increasing metabolism, which effectively burns additional fat from the body.
Green Coffee Bean Extract Side Effects & Safety
While green coffee bean extract benefits are positive, side effects of the extract can occur if not taken or used as directed.
Consumers should know that even though it contains less caffeine than roasted beans, caffeine side effects can occur.
Depending on the amount of caffeine ingested, individuals may experience jitteriness, insomnia, an increased heart rate, and sometimes an upset stomach or nausea.
When consumed in large amounts, green or roasted beans can contribute to headaches, agitation or anxiety, an irregular heartbeat (arrhythmia), and even tinnitus (ringing in the ears).
Limited information is available regarding negative interactions of the bean extract with over-the-counter or prescription medications.
To be on the safe side, always confirm with a physician regarding potential interactions or complications of green coffee bean extract, especially if you’re diagnosed with a medical condition or are taking prescription medications.
Does Green Coffee Bean Extract Work For Weight Loss?
Despite its being mentioned on the Doctor Oz show as a supplemental product that works to enhance weight loss without diet or exercise, it is recommended that individuals seeking long-term weight loss and maintenance incorporate diet and exercise with any supplement for optimal benefits.
In fact, an article in Science Daily determined that green coffee bean dietary supplements don’t work to prevent weight gain (tested on obese laboratory mice) in conjunction with a high-fat diet. Some benefits were noted with those on a low-fat diet.
While the extract may help contribute to weight loss, combine it with a healthy, nutritious and well-balanced diet and moderate exercise for the greatest benefits.
Green Coffee Bean Extract Reviews
Scientific evidence has determined that coffee drinkers may have a decreased risk of high blood pressure, obesity, and certain metabolic orders such as type 2 diabetes.
However, quality and components found in a variety of supplements differ depending on manufacturer such as Leptin and country of origin
For the best in green coffee bean extract benefits, the extract should contain a minimum of 50% chlorogenic acid taken at a 1,600mg daily dose. It’s the amount of chlorogenic acid that matters!
