Similar to a lot of dietary supplements or prescription drugs, the amount provides an important role with regards to negative effects. If taken without careful attention, even the most herbal supplement can cause surprising effects. Similar logic can be applied here. Precisely what is the proper amount of tea?
Some of the more important active substances of tea are caffeine and catechin. Both help with using body fat as the source to make energy which is called thermogenesis. This procedure in return enhances metabolic function. Boosted metabolic rate burns fat quicker in the body.
There have been countless scientific studies on caffeine and how it impacts human body. Many nutritionists are saying in general more than 500mg of caffeine in a day is too much. It can be unhealthy causing side effects like insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health specialists also agree that level of sensitivity to caffeine differs by an individual, however 300mg or less is regarded a safe amount.
In a cup of tea, one can find around 20mg of caffeine. Compare to other caffeinated drinks, it is a small amount. In a single cup of coffee there are approximately 100mg of caffeine. If tea is the only caffeinated beverage taken then it should not be a problem. However if additional caffeinated beverages are consumed during the day, then it is critical to look at the entire daily dosage of caffeine.
There also have been a number of laboratory tests about dosage. A daily amount of 800mg of EGCG was successfully tested without any negative effects. A single cup of tea possesses roughly 100mg of EGCG, which is 8 cups of tea. Most lab evaluations suggest more EGCG implies greater fat reduction, yet some medical experts advise that large quantity of isolated compound from herbs may be a problem. It is hard to make an absolute conclusion based on laboratory research, yet numerous medical experts are saying 300mg of EGCG is the best dosage to consume in a day. There are actually successful lab experiments with the dosage of 300mg versus cancer cells and weight reduction.
Because of the growing popularity of green tea, much more tests are going to be conducted. In the meantime, 300mg seems to be an ideal amount for both caffeine and EGCG.
