By Joseph Scott


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.

As with countless dietary supplements or prescription drugs, dosage provides an important role with regards to adverse effects. If consumed without care, even the most healthy supplement may cause unexpected effects. Similar reasoning can be applied here. Precisely what is the ideal amount of tea?

Two active contents of tea are caffeine and catechin. Both of them assist with utilizing body fat as the supply to generate energy which is referred to as thermogenesis. This process in return raises metabolic rate. Improved metabolism burns body fat more quickly in the body.

Various analyses on caffeine and its impact on human body have been carried out. A lot of professionals are stating in most cases more than 500mg of caffeine in a day is too much. It could be harmful causing unwanted effects which include insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Experts furthermore agree that level of responsiveness to caffeine ranges by an individual, however 300mg or less is considered to be a risk-free dosage.

Single cup of tea possesses around 20mg of caffeine. It is a small amount. Single cup of coffee possesses around 100mg of caffeine. When tea is the only caffeinated drink consumed then it should not be a problem. However when additional caffeinated drinks are consumed throughout the day, then it is important to look at the total daily dose 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.

Due to the increasing interest in green tea, even more lab tests are going to be conducted. As for now, 300mg appears to be a good amount for both caffeine and EGCG.
