Should Drinkers Be Concerned With 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?

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.

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.

There have also been some laboratory tests about dosage. A daily amount of 800mg of EGCG was successfully tested without side effects. A single cup of green tea includes roughly 100mg of EGCG, which is about 8 cups of green tea. Lots of clinical evaluations suggest more EGCG implies greater fat burning, however some health specialists warn that large amount of isolated ingredient from herbal products might be a problem. It is challenging to come to a definite conclusion based on lab tests, yet many researchers are suggesting 300mg of EGCG is a proper dose to take daily. There are actually quality lab outcomes using the dosage of 300mg fighting cancer cells and weight reduction.

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.
