Green coffee beans are the coffee beans that not roasted. These beans have a higher level of chlorogenic acid, which is normally displaced or destroyed in the roasting process. Chlorogenic acid is believed to have health benefits for combating cardiovascular diseases, contributing to weight loss, and prevention of contracting chronic conditions such as diabetes.
Green coffee beans became known for its contribution to better health, when it was originally mentioned by Dr. Oz on his TV show in early 2012. It was mentioned in connection with the capability to induce rapid weight loss with minimal effort. The mode of operation is not yet fully understood, but it appears that metabolic functions rates are greatly increased.
There are no serious side effects noted with the use of green coffee bean. Some studies have shown that, when it is taken in prescribed amounts, it can contribute to reduced blood pressure in certain individuals. Over a 12-week period, the recommended dosage of 80 – 200 mg has shown a moderate weight loss, and as much as 10% of the body fat in some people who may be considered as obese. The green coffee bean extract has quickly become the top selling weight loss supplement.
It is important to remember that green coffee bean contains caffeine, which has been linked to some negative health effects. Consumption should be carefully regulated, and it may necessary to consult your family doctor, before embarking on any weight loss program, and green coffee bean is no different.
There have been no significant adverse effects noted in human trials of Green Coffee extract, but there a few side effects that have been connected with the consumption of coffee, and have been noted as green coffee extract side effects.
One of the major green coffee extract side effects, is the apparent contribution to the condition of osteoporosis.
Caffeine appears to increase the amount of calcium that is dissolved and passed in urine. Calcium contributes to bone formation and if there is not enough present, bones can become brittle and weak. The maximum recommended dosage of daily consumption of caffeine should be limited to 300 mg per day which is about the amount of caffeine in 10- 8 oz cups of coffee.
Over consumption of caffeine has been associated with insomnia, restlessness, anxiety, and sometimes it can also attribute to increased heart rates. Although there is no direct correlation, pregnant and breast-feeding women should avoid heavy consumption of caffeinated products.
Caution must be exercised when consuming caffeine, as it has also be known to cause vomiting and nausea.
Along with nervousness, and restlessness, caffeine does nothing to help anxiety.
Research shows that caffeine can affect the manner in which the body metabolizes sugar, and the caffeine in green in green coffee bean extract may contribute to unstable blood sugar compositions. Diabetics that consume caffeine must regularly monitor the levels of sugar in the blood.
Caffeine has also been associated with the occurrence of diarrhea, and irritable bowel syndrome.
High levels of consumption of caffeine has also been linked to other conditions, such as glaucoma. In patients with glaucoma, there has been a noted increase in the pressure in the eye, which may be caused by dilation of the blood vessels. There has also been reports of increased blood pressure in individuals with already high blood pressure, who consume green coffee bean extract.
There has been very little concrete evidence to suggest that there are serious side effects that are directly related to the use of green coffee extract, however much of the negative effects are noted with consumption of caffeine.
Some research shows that results may be different in males, than those achieved in females.
In a recent study where 117 males were tested, Green coffee been was shown to be quite effective in reducing blood pressures, while no significant side effects were noted. It may be possible, that it may affect different people differently, and a much wider testing sample may be needed for more representative results. The study did not take the background or lifestyle nor medical history of the test subjects into account.
In another short clinical trial of 28 Japanese subjects, who were tested for a period of 60 days, there were some positive effects noted with the incidences of hypertension, and there was very little chemical changes noted in the composition of minerals in the blood, such as copper, magnesium, zinc and vitamin B complex.
Green coffee bean extract appears to increase the rate and the manner in which glucose and fats are absorbed the small intestine, it also appears to reduce the amount of insulin which results in increased metabolic rates.
During many of the studies that were conducted over several months, much of the adverse effects were all unnoticed.
There has been a strong positive correlation, between weight loss, an the consumption of green coffee extract, but as with any unregulated supplement, there is a need to exercise some caution. Weight loss products, by the very nature of operation, can produce harmful side effects, if they are consumed indiscriminately.
Caffeine has shown to cause problems in many people, but green coffee bean extract is an all-natural product without the addition of synthetic substances. Although the product is not regulated or can be approved by the FDA as a drug, because it is actually sold as a food supplement, it contains much less caffeine than regular coffee beans and retains the benefits of chlorogenic acid that is destroyed when coffee beans are roasted.
The maximum dose of green coffee bean extract, as recommended by some producers, contain less than 20% of that in a cup of espresso. The adverse effects may attributed to the effects of consumption of caffeine, and it may be advisable to lower the dosage of the extract, if any ill effects are experienced.
The major concern may be with the collective effect known as “malabsorption”, which is associated with irregular heart beats, and excessive weight loss, or malnutrition, as the useful as minerals and vitamins are absorbed, rather than being passed through for assistance in metabolizing food in the small intestine. Improper metabolism can lead to serious heath conditions and may even lead to cardiovascular malfunctions.
