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.
A green coffee extract is an extract un-roasted, green coffee beans. Green coffee extract has been used as a weight-loss supplement and as an ingredient in other weight-loss products. Its efficacy and mechanism of action have been the subject of controversy.
Green coffee beans are coffee beans that have not yet been roasted. The roasting process of coffee beans reduces amounts of the chemical chlorogenic acid. Therefore, green coffee beans have a higher level of chlorogenic acid compared to regular, roasted coffee beans. Chlorogenic acid in green coffee is thought to have health benefits for heart disease, diabetes, weight loss, and others.
A 2011 review found tentative evidence that green coffee extract promotes weight loss; however, the quality of the evidence was poor. This review looked at three publishedrandomized controlled trials of green coffee extract, totaling 142 participants, and found a small effect. The review stated that more rigorous trials with longer duration were needed to assess the efficacy and safety of green coffee as a weight loss supplement
The Dr. Oz show referred to it as “The green coffee bean that burns fat fast” and claims that no exercise or diet is needed.In April and September 2012, The Dr. Oz Show featured green coffee extract, and conducted its own non-scientific study as to its efficacy.
Svetol was developed by Berkem, a French phytochemical and plant extract company. The product was first marketed as a dietary supplement in 2002.By 2005 it was the active ingredient in Coffee Slender, a popular weight-loss product in Norway, and the product launched in the UK the following year. At the 2006 Health Ingredients Europe conference it received the Bronze Award in the best ingredient category.
In January 2008, Naturex, an international natural ingredient manufacturer, acquired Berkem's clinically tested plant extract division, of which a prime product was Svetol,and Naturex brought Svetol to the U.S. market.
Svetol is one of the two brands of green coffee extract that is standardized to contain at least 45% chlorogenic acid. In 2013 EuroPharma added Svetol to its line
Green coffee beans are coffee beans that have not yet been roasted. These coffee beans contain a higher amount of the chemical chlorogenic acid. This chemical is thought to have health benefits. For high blood pressure it might affect blood vessels so that blood pressure is reduced.
For weight loss, chlorogenic acid in green coffee is thought to affect how the body handles blood sugar and metabolism
Other studies (in mice and rats) have shown that chlorogenic acid can reduce body weight, reduce fat absorbed from the diet, reduce fat stored in the liver and improve the function of the fat burning hormone adiponectin .
Chlorogenic acid has also been shown to drastically improve cholesterol and triglyceride levels in rats. These are important risk factors for heart disease .
Does Green Coffee Have Too Much Caffeine In?
With such a long and impressive list of benefits, it’s natural if you wonder about the side effects. After all, there has to be some potential side effects that balance out all the good things that green coffee offers, right? In both studies, there were no side effects reported at all. There were no reports of any symptoms associated from drinking too much coffee. But is it possible?
Who Is Green Coffee Extract NOT Safe For?
So what are the possible dangers? Like just about any medication or supplement, there are some possible risks:
You may be allergic to coffee beans or to caffeine. This is extremely rare, but it is possible. People who are allergic to coffee can show symptoms such as hives and breathing difficulties. If you also can’t drink soda or tea, then you are allergic to the caffeine. If you can’t drink decaffeinated coffee, then you’re allergic to the coffee itself.
Either way, obviously you cannot take green coffee supplements.
Women who are pregnant or breastfeeding should not take pure green coffee extract. Most reputable green coffee supplement manufacturers have a warning to this effect on their websites and on their products. It is not because green coffee supplements have been proven to be dangerous for women in these conditions. It’s a reasonable precaution because there has not been enough conclusive data from studies involving these types of women, to discount the possibility.
So to sum it up, if you are an adult with no serious medical condition besides obesity or being overweight, then taking green coffee capsules is the PERFECT supplement to your diet and exercise regimen. You get to enjoy great health benefits including weight loss, and yet you do not have to worry at all about any green coffee side effects. This supplement is generally safe to take which means that by taking it, you have a lot to gain, and nothing to lose (except fat of course).
