Facts About Green Tea Side Effects

By Jeffrey Singer


TV programs and health magazines have been promoting green tea as an excellent supplement for fat loss. With the growing curiosity of tea, many are wondering the safeness of the supplement. Many of the press promoting the benefits of tea are not discussing enough of the side effects. Fully knowing the potential side effects is essential to be able to take benefits with no harmful 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 components of tea are caffeine and catechin. Both together help out with utilizing fat as the source to generate heat which is called thermogenesis. This process in return increases metabolism. Enhanced metabolism burns fat more quickly in the body.

There were many researches on caffeine and how it affects human body. Many health experts are stating in general above 500mg of caffeine a day is too much. It can be harmful resulting in side effects which include insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Industry experts furthermore agree that level of sensitivity to caffeine varies by an individual, however 300mg or less is perceived as a risk-free dosage.

A single cup of tea carries about 20mg of caffeine. Compare to coffee, it is a small amount. A single cup of coffee carries about 100mg of caffeine. If tea is the only caffeinated beverage taken then it should not be a concern. But when other caffeinated beverages are consumed throughout the day, then it is critical to consider the combined daily dosage of caffeine.

There also have been some laboratory tests related to the amount of tea. A daily dose of 800mg of EGCG has been successfully tested with no side effects. A single cup of tea comes with around 100mg of EGCG, so that is 8 cups of green tea. A lot of clinical tests claim more EGCG means more fat reduction, however some experts advise that an excessive amount of isolated element from herbal products may be problematic. It is challenging to make a definite conclusion based on clinical studies, but numerous experts are saying 300mg of EGCG is an ideal dosage to take daily. There are successful laboratory experiments using the dosage of 300mg fighting cancer cells and weight loss.

With the increasing curiosity about green tea as an alternative medicine, a lot more lab tests will be conducted. For now, 300mg seems to be a good amount for both caffeine and EGCG.
