Does Green Coffee Bean Extract Work? Uses, Side Effects and Warnings

What’s the Deal with Green Coffee Bean Extract?

You’ve probably heard about green coffee extract on T.V. or from a friend. Several famous doctors have been spreading the word recently about the surprising weight loss results that many people are getting.

What is green coffee bean?

As the name implies, “green coffee” is simply unroasted seeds—aka beans—from Coffea, the plant that gives us so many of our morning brews. Coffee contains hundreds of compounds, many of which may have healthful benefits.

How Does Green Coffee Bean Work?

Green coffee bean contains polyphenols, including chlorogenic acids, which, like grape seed extract and green tea, have antioxidant that help the body neutralize harmful free radicals. Research has also shown that the chlorogenic acid in green coffee bean has an antihypertensive effect on rats and humans that promotes normal blood pressure.

Unlike coffee beverages, green coffee bean extract is low in caffeine and is not a stimulant. Chlorogenic acids are also destroyed when coffee beans are roasted and their benefits are not available in coffee drinks.

Chlorogenic acids support the weight loss benefits of green coffee bean in a couple different ways. First, promote balanced blood sugar by inhibiting the release of glucose within the body. Secondly, chlorogenic acids boost the metabolic output of the liver, which burns more fat. This dual mechanism works to support lean body mass by hindering the absorption of fat and weight gain.

What it’ll do for you?

Green coffee bean extract has gained quite a bit of buzz recently as a weight-loss supplement. Many websites sell green coffee pills, and a major coffee company has even started selling a beverage spiked with the extract.

In 2012 a study published by Diabetes, Metabolic syndrome and Obesity, found that on average test users lost 18 pounds in just 12 weeks while taking green coffee bean as a supplement.

Before we get into chlorogenic acid it’s good to understand the difference between coffee and green coffee beans.

All coffee beans are originally green beans that are removed from the fruit of a tree. Roasting the beans develops the characteristics that we know such as the different shades of brown and dark beans depending on your preference.

The beans are left out in the sun to dry, then are pounded and broken apart to get the coffee seed alone. This process can be done in different ways, but majority of companies have incorporated machines to handle the process.

Once the seeds have been separated from the fruit it goes through a few processes depending on the manufacturer. The beans are taken through either a washed or wet processes that gives the coffee beans higher notes and fuller flavor.

The coffee beans are then sorted and bagged according the grade level.

The roasting of coffee beans in regular coffee increases antioxidant levels and caffeine levels while minimizing chlorogenic acid benefits. Chlorogenic acid benefits are what is highlighted and known for green coffee bean.

Although green bean coffee has caffeine, no reports of it having side effects were ever reported.

The process for green coffee bean starts by soaking the coffee beans and then extracting Chlorogenic acid. Pure green coffee bean weight loss has been an added advantage of early research on Chlorogenic acid.

The main reason green coffee bean has seen an explosion in popularity is because of its weight loss benefits. Early randomized controlled trials have shown significant weight loss in groups that used green coffee bean as a supplement.

So what makes green coffee bean effective?

It’s widely known that the main component to this surge in weight loss comes from chlorogenic acid.

When it comes to green coffee beans effect on heart health we can look at what the extract does to the body.

Risk and side effects of Green Coffee Bean

All in all, green coffee bean shows to have an impact on weight loss, metabolism, blood pressure, and glucose levels. For this many other benefits can be derived from green coffee such as all that have been listed in this article.

Readers should also consider that majority of studies were small so it’s crucial that a diet and lifestyle change be made when trying any product to lose weight or gain some form of health.

Eating less processed food, dieting, and a healthy workout regimen can have a greater impact on your health than any supplement you buy.

These supplements are meant to add as a benefit to an already established healthy lifestyle an added boost, it does not serve to give a miracle transformation.
