What You Should Know
Green Coffee Bean Extract is one of those new weight loss supplement ingredients that gains a huge following extremely quickly. We first noticed the ingredient when Hydroxycut removed several products from the market and replaced the garcinia cambogia with green coffee bean extract. Garcinia cambogia was originally included as a fat burner, so we assume the green coffee bean extract was used for the same purpose. When coffee is boiled, a substance called cafestol is extracted. This is the part of coffee that causes negative side effects. Essentially, green coffee bean extract is supposed to supply all the healthy benefits of coffee without any negative side effects, but it is hard to get a clear answer about the stimulant effect of the extract.
List of Ingredients
- Extract of an Unripe Coffee Bean
There have been several small studies on the weight loss benefits of green coffee bean extract. The studies have used more than 1,000 mg of the extract, which is much more than is commonly found in typical green coffee bean extract supplements. Some manufacturers claim they are just playing it safe with a lower dose until larger studies are completed and others don’t address the clinical research at all.
We also found some studies on the effect of green coffee bean extract, specifically the chlorogenic acid, on blood pressure. According to the studies, the extract can lower blood pressure when taken regularly.
There is no doubt that green coffee bean extract offers some health benefits, but until large-scale studies are completely on humans, these studies are irrelevant. We cannot take the effect of a supplement on mice and expect the same effect on humans. Humans have much more stress and mental connection with food than mice so we are more apt to overeat for all the wrong reasons. In many cases, genetically altered mice are used for the studies and we hope the humans taking the supplements are not genetically altered in any way.
- May increase weight loss.
- May decrease blood pressure.
- May be a safe alternative to stimulants.
- Some clinical studies have been completed.
- No large-scale clinical studies on humans.
- Animal studies cannot be used to gauge human effect.
- Not as effective as caffeine at boosting metabolism.
Ideally, green coffee bean extract would be taken as part of a combination supplement. The dieter could see some health benefits from the chlorogenic acid, but whether or not the effects are statistically significant is yet to be proven. We suggest using green tea, caffeine and chromium as the base three ingredients in your supplement until further research is completed.
