Green Tea Can Be Consumed Without Any 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.

Similar to many supplements or medicines, the amount plays an important role with regards to unwanted effects. If taken without careful attention, even the most herbal supplement results in unexpected reactions. Identical logic can be applied here. Just what exactly is the safe amount of tea?

The most active substances of tea are caffeine and catechin. Both of them help with using fat as the supply to generate energy which is known as thermogenesis. This process in return boosts metabolic rate. Enhanced metabolic process burns body fat more rapidly in the body system.

There were many scientific tests on caffeine and how it influences human body. Lots of health specialists are saying in most cases beyond 500mg of caffeine in a day is too much. It could 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 ranges by an individual, but 300mg or less is perceived as a low risk dose.

Single cup of tea possesses approximately 20mg of caffeine. Compare to other caffeine containing drinks, it is a small amount. Single cup of coffee possesses approximately 100mg of caffeine. When tea is the only caffeinated drink consumed then it should not be a concern. However when additional caffeinated beverages are consumed during the day, then it is important to check the combined daily dose 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.
