Are There Any Side Effects With Green Tea?

By Tom Nelson


Health television shows and periodicals are promoting tea as a beneficial supplement for weight reduction. With the raising interest of tea, a lot of people are concerned with the safeness of the supplement. Many of the press supporting the advantages of tea are not explaining enough of the side effects. Thoroughly understanding the possible side effects is important to be able to take health rewards with no undesirable outcomes.

As with countless dietary supplements or medications, the amount plays an important role in terms of adverse effects. If taken without caution, even the most herbal supplement allows surprising reactions. Same reasoning applies here. Precisely what is the ideal amount of tea?

Among the most active contents of tea are caffeine and catechin. These two assist with taking body fat as the resource to make heat which is referred to as thermogenesis. This process in return improves metabolism. Enhanced metabolic function burns fat much faster in the human body.

There have been quite a few studies on caffeine and how it affects human body. A lot of health experts are claiming usually beyond 500mg of caffeine a day is too much. It could be unhealthy causing adverse reactions which include insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health specialists also acknowledge that sensitivity to caffeine ranges by an individual, but 300mg or less is regarded a good dosage.

Within a single cup of tea, one can find approximately 20mg of caffeine. Compare to other caffeine containing drinks, it is a small amount. Single cup of coffee possesses roughly 100mg of caffeine. When tea is the only caffeinated beverage consumed then it should not be an issue. But if additional caffeinated drinks are consumed during the day, then it is important to consider the combined daily amount of caffeine.

Scientists carried out tests related to the amount of tea. A daily dose of 800mg of EGCG has been successfully tested without any uncomfortable side effects. A cup of tea comes with roughly 100mg of EGCG, so that is 8 cups of green tea. Many clinical experiments suggest more EGCG means more weight loss, yet some professionals advise that too much of one compound from herbal plants can be a problem. It is not easy to come to a definite conclusion based on clinical tests, still many health specialists are stating 300mg of EGCG is a safe dosage to take in a day. There are successful lab tests with the dose of 300mg fighting cancer cells and weight reduction.

With the increasing popularity of green tea, additional tests will likely be done. In the meantime, 300mg seems to be a good dosage for both caffeine and EGCG.
