How Serious Are Green Tea Side Effects?

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.

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.

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.

Industry experts carried out lab tests concerning dosage. A daily amount of 800mg of EGCG was successfully tested without unintended effects. One cup of green tea has close to 100mg of EGCG, which is 8 cups of green tea. Many laboratory experiments claim more EGCG equals to more fat burning, yet some health specialists advise that large amount of one compound from herbal products could be a problem. It is challenging to come to a definite conclusion based on clinical reports, still a good number of experts are saying 300mg of EGCG is an ideal dose to take in a day. There have been successful laboratory tests using the dosage of 300mg against cancer cells and weight reduction.

Because of the growing use of green tea as a fat burning aid, even more lab tests are going to be conducted. For the time being, 300mg seems to be an ideal dosage for both EGCG and caffeine.
