Are There Any Unwanted Effects From Drinking Too Much Green Tea?

By Peter Martin


Health related television shows and journals have been promoting green tea as a good supplement for weight loss. With the growing interest of tea, many are questioning the safeness of the supplement. Many of the media supporting the advantages of tea are usually not identifying enough of the unwanted effects. Thoroughly understanding the possible side effects is vital to be able to take health rewards with no harmful consequences.

Like numerous dietary supplements or medicines, dosage provides an important role in terms of side effects. If consumed without care, even the most healthy supplement results in surprising reactions. Same reasoning can be applied here. Precisely what is the ideal amount of tea?

Two active components of tea are catechin and caffeine. Both help with taking body fat as the resource to produce heat which is known as thermogenesis. This process in return boosts metabolism. Increased metabolic rate burns body fat faster in the body.

Various experiments on caffeine and its effect on human body system have been performed. Numerous nutritionists are claiming typically greater than 500mg of caffeine in a day is too much. It can be damaging resulting in negative effects like insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health experts furthermore acknowledge that responsiveness to caffeine differs by an individual, but 300mg or lower is considered to be a low risk amount.

In a cup of tea, there are about 20mg of caffeine. Compare to other caffeinated drinks, it is not a lot. In a cup of coffee there are about 100mg of caffeine. If tea is the only caffeinated beverage consumed then it should not be an issue. However if other caffeinated drinks are consumed throughout the day, then it is important to look at the overall daily dosage of caffeine.

Tea researchers performed tests regarding the amount of tea. A daily dose of 800mg of EGCG was tested with success and without any unwanted effects. A cup of tea contains approximately 100mg of EGCG, which is around 8 cups of tea. Numerous laboratory experiments suggest more EGCG implies more fat reduction, still some health professionals advise that large quantity of single compound from herbs can be a problem. It is challenging to make an absolute conclusion based on laboratory experiments, still a lot of health experts are claiming 300mg of EGCG is the best dose to consume in a day. There are successful scientific reports with the amount of 300mg fighting cancer cells and weight reduction.

Because of the raising use of green tea as an alternative remedy, a lot more tests will be done. In the meantime, 300mg appears to be a safe dose for both EGCG and caffeine.
