PRLog - Nov. 15, 2012 - BROOKLYN, N.Y. -- After Dr. Mehmet Oz’s appearance on his show introducing this “miracle” dietary supplement back in May 2012, the sales of green coffee extract has exploded and has been flying off vitamin store product shelves. According to clinical studies, green coffee extract is not just hype. Its claim to weight loss fame stands up to the test of rigorously-designed clinical research. Studies suggest that it may be an effective natural product for weight loss in overweight adults. So what is the chemical ingredient in green coffee extract that is responsible for this frenzy? Chlorogenic acid. Let’s take a look at chlorogenic acid and green coffee extract and their proven benefits.
Green Coffee Extract
Chlorogenic acid’s Health Benefits
Green coffee extract is made from green coffee beans of two coffee plants: Arabica and Robusta. Primarily grown in Central America and in South America, Arabica is the most consumed and produced type of coffee, in beverage form, due to its superior quality and aroma. Robusta is typically grown in Central and West Africa, South-East Asia and Brazil. Unlike traditional coffee beans that are roasted to make the coffee beverage we’re so addicted to, green coffee beans are not roasted. In their 100% purest form, green coffee bean extract maintains a naturally high content of chlorogenic acid, which helps the liver process fat easily. Chlorogenic acid is an organic compound naturally found in plants and fruits including peaches, prunes, and blueberries, and green coffee extract. Chlorogenic acid is derived from cinnamic acid, which as its name reveals, comes from cinnamon oil, and has known anti-oxidant and anti-inflammatory benefits. In addition, many published scientific studies have shown that chlorogenic acid exhibits health benefits such as cardiovascular health improvement, as a result of its antioxidant properties, diabetes type 2 prevention, Alzheimer’s disease prevention, and weight loss benefits.
It’s effects on the human body has been thoroughly studied. Chlorogenic acid prevents glucose from being released from the liver into the blood stream. Blocking additional glucose storage allows the glucose present in the body’s fat deposits to be used up which helps facilitate weight loss. Because glucose metabolism is better controlled, chlorogenic acid helps lower blood glucose levels. Chlorogenic acid also increases metabolism which helps prevent weight gain and lowers blood pressure. The antioxidant present in green coffee extract is similar to that found in green tea.
A scientific study conducted with 10 healthy males and females demonstrated that chlorogenic acid from green coffee extract is highly absorbed and readily metabolized by the body. Many other studies have demonstrated chlorogenic acid’s excellent antioxidant properties.
Green Coffee Extract’s Effectiveness as a Dietary Supplement
A number of well-designed clinical studies have evaluated green coffee extract for its safety and effectiveness in the reduction of weight. A 2012 randomized, controlled research study conducted by Dr. Joe Vinson looked at the effects of Green Coffee Antioxidant (GCA®) on 16 overweight adults (8 men, and 8 women) whose body mass index (BMI) measurements were 25-30. The adults were given 350mg GCA®, including a high dose of 1050mg taken 3x daily and a low dose of 700mg taken twice daily, and a placebo (a inactive formula) taken twice daily over a 22-week period. The study revealed that the adults who were given GCA® experienced significant weight reduction, as a well as a drop in systolic and diastolic blood pressure and heart rate. For those receiving the high and low dose, the mean (or average) change in weight measurement was 10.5%, 10.3% change in BMI measurement, and 15.8% change in percent body fat. For both GCA® doses, the change in weight, BMI and percent body fat were equally significant. There were no reported side effects with GCA®.
Other human studies were conducted with another branded green coffee extract called Svetol®. Svetol®
Dr. Oz and his medical team also conducted their own randomized, placebo-controlled clinical study with 100 overweight women whose BMI were between 25 and 45. The women received either the green coffee bean extract or a placebo at 400mg, and were instructed to take them three times a day, 30 minutes before each meal, over a course of two weeks. After two weeks, the women who received the green coffee extract lost an average of two pounds, while those who received placebo lost one pound.
These studies suggest that green coffee bean extract dietary supplement may be effective in significant reducing weight in overweight adults. So now that we know that the evidence suggests that green coffee extract works, how do you know which brand is right for you?
Brand Choice Recommendations
Yes, there are so many brands of green coffee extract on the market today, and it is difficult to know which brand is the best. Everyday Vitamin will point out some recommendations from Dr. Oz.
The extract used in the January 2012 Vinson study contained GCA® which contains 46% of chlorogenic acid. Svetol®, the other brand has also been shown in several clinical studies to have superior absorption and bioavailability (the degree of availability of a given dosage for the body’s use), and to cause significant reduction to the percentage of body fat. Svetol® also contains 45% chlorogenic acid. GCA® and Svetol® are available in 200mg, 400mg and 800mg dosages.
On his website, http://www.doctoroz.com, Dr. Oz urges consumers to conduct due diligence when considering purchasing a specific brand of green coffee extract. He recommends the following:
• Choose a supplement that contain either GCA® or Svetol®.
• A minimum dosage of 200mg of either GCA® or Svetol®, but 800mg twice daily is the regimen proven effective in the research.
• Reading the supplement facts label to ensure that green coffee extract is clearly listed as the only ingredient (fillers and artificial ingredients should not be listed) and warns consumers not to be deceived by products that overtly tout the product’s benefits.
• Find out if the brand is produced in a FDA registered laboratory.
• Find out if the brand is manufactured under the strict guidelines of the U.S. Food and Drug Administration.
It is important to conduct thorough research to find out which brand is 100% pure and contains the rawest form of green coffee bean extract. Not all green coffee extracts are created equal.
