How To Avoid Green Tea Side Effects?

By Richard Davis


TV programs and medical periodicals have been advertising green tea extract as an excellent supplement for reducing weight. Because of the growing interest of tea, many are concerned about the safeness of the supplement. A lot of the presses promoting the advantages of tea are not identifying enough of the unwanted side effects. Thoroughly knowing the potential unwanted effects is crucial to be able to take health benefits with no harmful consequences.

As with a lot of dietary supplements or prescription drugs, the amount has a major role in terms of negative effects. If taken without caution, even the most healthy supplement may cause unanticipated reactions. Similar reasoning is true here. Precisely what is the safe amount of tea?

The most active substances of tea are caffeine and catechin. Both of them help out with using fat as the supply to produce heat which is called thermogenesis. This process in return speeds up metabolism. Enhanced metabolic function burns body fat more rapidly in the human body.

There were countless researches on caffeine and how it affects human body. Many health experts are stating usually greater than 500mg of caffeine a day is too much. It could be harmful resulting in unwanted effects like insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health specialists furthermore acknowledge that responsiveness to caffeine ranges by an individual, however 300mg or lower is considered to be a safe amount.

Within a cup of tea, one can find roughly 20mg of caffeine. Compare to other caffeine containing drinks, it is not much. Within a cup of coffee there are approximately 100mg of caffeine. When tea is the only caffeinated beverage taken then it should not be a concern. But when additional caffeinated drinks are consumed throughout the day, then it is critical to consider the overall daily dosage of caffeine.

Scientists conducted lab tests concerning the amount of tea. A daily amount of 800mg of EGCG has been successfully tested without any unwanted effects. One cup of green tea carries close to 100mg of EGCG, so that is 8 cups of green tea. Lots of lab evaluations claim more EGCG means more fat burning, yet some medical experts warn that too much of isolated element from herbal products can be a problem. It is difficult to come to a definite conclusion based on clinical studies, yet a good number of health professionals are saying 300mg of EGCG is an ideal dose to consume daily. There are actually reliable lab outcomes using the dose of 300mg fighting cancer cells and weight loss.

With the growing popularity of green tea, much more lab tests are going to be done. As for now, 300mg seems to be a good dosage for both caffeine and EGCG.
