Everyone is talking about Green Coffee Extract. It is the hottest product on the Internet. It gives you energy and helps you lose weight. Even stores have come out with a low calorie drink that has the extract in it. Of course, given the history of weight loss discoveries people are also wondering if it is safe. Numerous studies have been made and have found that not only does GCBE promote weight loss, an average of 17 lbs in 6 weeks but has not found any side effects with the taking of it in average doses. An average dose ranges from 700 mg to 1050 mg.
In a recent 22 week study, funded by Applied Food Services, Inc. subjects lost an average of 22 lbs and no adverse side effects were found. GCBE has been associated with weight loss and with all weight loss products there is always good reason to be cautious.In theory, the caffeine content of GCBE could potentially cause problems for some people. However, since GCBE contains only about 10% caffeine by weight, a high daily dose contains no more than about 20% of the caffeine content of a strong cup of coffee.
Animal studies have found evidence that chlorogenic acids from green coffee bean extract can reduce blood pressure. Based on this, researchers have started conducting human trials.
Right now there are not enough studies to prove that GCBE lowers blood pressure but the researchers are very excited about results. Chlorogenics Acids and GCBE have been found to lower blood pressure in over stimulated rats and humans in a controlled study. No adverse results were found.
Roasted (as opposed to green) coffee beans contain the substances kahweol and cafestol, which appear to increase levels of LDL ("bad" cholesterol). The fact that GCBE does not contain these substances is used as an argument in its favor. However, these substances remain in the coffee grounds and so they are also not present in standard beverage coffee, so this is probably not a significant point. Unfiltered or boiled coffee, with the grounds left in, however, may present a risk.
Of course GCBE has also shown a bit of promise for aiding weight loss, perhaps in part due to its chlorogenic acid content. The caffeine in GCBE proves to be a weight loss benefit.
In studies GCBE is thought to be a safe substance. In human trials, no significant adverse effects have yet to been seen.
In the large human trial of GCBE for hypertension noted above, the extract was most effective when taken at a dose of 185 mg daily.
Since green coffee bean extract typically contains about 30% chlorogenic acids, this works out to a dose of about 60 mg of chlorogenic acids daily. Another study used 140 mg of purified chlorogenic acids daily. This is important in weight loss and in reducing blood pressure.
In theory, the caffeine content of GCBE could potentially cause problems for some people. However, since it contains only about 10% caffeine by weight, a high daily dose contains no more than about 20% of the caffeine content of a strong cup of coffee.
Maximum safe doses in pregnant or nursing women, young children, or people with liver or kidney disease have not been established.
I write a blog that helps women over 40 be healthier and lose weight(don't worry, under 40 and men can read it too) Find the information that has helped me at http://fatlostquickly.com/
