TV programs and medical periodicals have been advertising green tea extract as a reliable supplement for weight loss. With the expanding interest of tea, many people are concerned with the safety aspects of the supplement. Many of the press promoting the benefits of tea are usually not explaining enough of the negative effects. Thoroughly knowing the potential negative effects is essential to be able to take health benefits without any damaging consequences.

Similar to many supplements or medicines, the amount plays a vital role when it comes to adverse effects. If consumed without care, even the most organic supplement results in unanticipated reactions. Identical reasoning applies here. So what is the right amount of tea?

A couple of active elements of tea are caffeine and catechin. Both of them assist with using fat as the resource to produce heat which is called thermogenesis. This process in return enhances metabolic function. Increased metabolism burns body fat much faster within the body.

A lot of analyses on caffeine and its impact on human body have been conducted. Numerous experts are saying normally above 500mg of caffeine in a day is too much. It can be harmful causing adverse reactions like insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Researchers furthermore agree that sensitivity to caffeine ranges by an individual, however 300mg or less is regarded a risk-free amount.

A single cup of tea possesses around 20mg of caffeine. It is a small amount. A single cup of coffee possesses around 100mg of caffeine. If tea is the only caffeinated drink taken then it should not be an issue. However if other caffeinated drinks are consumed during the day, then it is critical to look at the total daily dosage of caffeine.

Tea researchers carried out lab tests about dosage. A daily dose of 800mg of EGCG has been successfully tested without having any unintended effects. One cup of tea possesses approximately 100mg of EGCG, so that is about 8 cups of tea. Most lab experiments indicate more EGCG equals to more fat reduction, still some professionals warn that large quantity of one compound from herbal products might be problematic. It is difficult to come to an absolute conclusion based on laboratory studies, still a lot of health experts are saying 300mg of EGCG is a proper dosage to take daily. There are actually safe clinical results using the amount of 300mg versus cancer cells and weight loss.

Because of the increasing interest in green tea, more laboratory tests are going to be conducted. In the meantime, 300mg appears to be an ideal amount for both caffeine and EGCG.
