While the beans contain dozens of chemical components, many of which produce a number of unique pharmacological effects, most people drink it for its caffeine.
In addition to caffeine, a large number of other components in green coffee include chlorogenic acid, lignans, and guinides – all believed to improve the metabolism of glucose (blood sugar) – in animal studies.
What does glucose have to do with weight gain? The body uses glucose as a form of energy.
When glucose from carbohydrates consumed from diet is not utilized, carbohydrates are converted into fat and stored in the body.
Chlorogenic acid is a common and natural compound found in many plants and not just the coffee plant. Not only is chlorogenic acid important for plant metabolism, it is believed to be beneficial in human metabolism as well.
A 2010 article defined a study of chlorogenic acid benefits in regard to weight loss in obese mice.
The study determined that chlorogenic acid showed significant benefits in reduction of visceral fat mass and lower body weight, as well as insulin levels (in mice supplemented with a 0.2% high-fat diet) in comparison to a control group of mice who were fed a high-fat (37%) diet.
What does that mean? It means while that the chlorogenic acid benefits can aid in weight loss, optimal benefits will be received in conjunction with a reduced fat diet coupled with exercise.
Because the chemical components such as chlorogenic acid and caffeine have been showed to moderately enhance metabolism, pure green coffee bean extract may be beneficial in modest weight loss attempts.
These components have also displayed some effectiveness in treatment of hypertension (high blood pressure).
The few clinical trials that have produced data regarding efficacy of the extract have shown that individuals diagnosed with mild hypertension taking between 93 mg and 185 mg of green coffee extract may reduce systolic and diastolic low-pressure after approximately 28 days of treatment.
Very few side effects of green coffee bean extract have been noted among users.
However, consumers should be aware that people may react differently to caffeine.
Common side effects of caffeine ingestion include jitteriness and insomnia, again depending on the time of day taken.
More severe reactions to caffeine, again depending on amount consumed, may also include anxiety, upset stomach, headaches, nausea, and in some cases, vomiting.
Some interactions with prescription drugs are possible. For example, it may moderately interact with adenosine as well as alcohol.
Alcohol can reduce the metabolism of caffeine in the body and lead to a high concentration of adverse caffeine affects. If you take Fosamax (for osteoporosis) or anticoagulant medications, avoid use of the beans altogether.
Be on the safe side and confer with your family physician before taking the supplement, especially if you’ve been diagnosed with a medical condition for which you are taking prescription medications or herbal remedies.
It should be noted that a coffee drinker may ingest approximately 0.5 to 1g of chlorogenic acid in regular brands, while 200 mg doses of some green tea and coffee extract supplements including Svetol® or Green Coffee Plus provide an equivalent of drinking three to five cups.
While precise dosage and recommendations can differ between individuals based on age, overall health, contributing medical conditions or factors, and weight, green coffee bean extract is generally considered safe when taken and used as directed.
Exact dosage for treatment of obesity in humans is still undetermined, but suggested doses average 10g of the extract for approximately 14 days.
Because verifiable information and data regarding safety of the extract for use by pregnant or breast-feeding women is lacking, it is recommended that any herbal supplements such as Garcinia Cambogia be avoided prior to discussion with healthcare providers.
Manufacturing processes, country of origin, and brands differ when it comes to green coffee for sale on the market today.
Look for brands that contain one major ingredient – chlorogenic acid. A number of manufacturers add useless fillers that reduce their efficacy. Choose green coffee bean extract that contains a minimum of 50 mg chlorogenic acid for optimal benefits.
