Facts About Green Tea Side Effects

By Jeffrey Singer


Talk shows and medical periodicals are promoting green tea as a good supplement for losing weight. Because of the raising interest of tea, many are concerned with the safety aspects of the supplement. Most of the press promoting the advantages of tea is usually not discussing enough of the side effects. Thoroughly understanding the possible unwanted effects is important to be able to take health benefits without any unwanted consequences.

Much like many dietary supplements or medicines, dosage has a significant role in terms of side effects. If taken without care, even the most natural supplement allows surprising effects. Same reasoning can be applied here. Precisely what is the ideal amount of tea?

Two active substances of tea are caffeine and catechin. Both help out with taking fat as the supply to make heat which is referred to as thermogenesis. This procedure in return increases metabolism. Enhanced metabolic rate burns body fat quicker within the body.

There have been a number of scientific studies on caffeine and how it influences human body. Numerous professionals are stating commonly greater than 500mg of caffeine per day is too much. It could be harmful causing adverse reactions such as insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Industry experts furthermore acknowledge that responsiveness to caffeine varies by an individual, but 300mg or less is considered to be a healthy amount.

A single cup of tea carries approximately 20mg of caffeine. Compare to other caffeine containing drinks, it is a small amount. A single cup of coffee carries approximately 100mg of caffeine. When tea is the only caffeinated drink taken then it should not be a concern. However if other caffeinated beverages are consumed throughout the day, then it is critical to look at the overall daily amount of caffeine.

Tea researchers carried out lab tests concerning the amount of tea. A daily amount of 800mg of EGCG was tested with success and zero unwanted side effects. A cup of tea comes with roughly 100mg of EGCG, which is about 8 cups of tea. Lots of lab experiments claim more EGCG equals to more fat reduction, but some professionals agree that large amount of isolated ingredient from herbal plants could be a problem. It is challenging to come to an absolute conclusion based on clinical research, but a great number of medical experts are claiming 300mg of EGCG is a good dose to consume in a day. There are actually successful scientific studies while using the dose of 300mg against cancer cells and weight reduction.

Because of the increasing availability of green tea as a natural supplement, much more laboratory tests are going to be conducted. In the meantime, 300mg seems to be a good amount for both caffeine and EGCG.
