By Kenneth Palmer


TV programs and medical journals are promoting tea as a reliable supplement for weight loss. With the raising curiosity of tea, many people are wondering the safety aspects of the supplement. Most of the press promoting the advantages of tea is usually not identifying enough of the unwanted side effects. Thoroughly knowing the possible negative effects is vital in order to take health benefits without having unwanted effects.

Like countless dietary supplements or medications, the amount plays an important role in terms of unwanted effects. If consumed without care, even the most organic supplement can cause unanticipated effects. Similar reasoning is applicable here. What exactly is the proper amount of tea?

A couple of active components of tea are caffeine and catechin. Both help with utilizing body fat as the supply to create energy which is known as thermogenesis. This process in return enhances metabolic function. Boosted metabolic function burns body 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.

Tea researchers conducted tests pertaining to dosage. A daily dose of 800mg of EGCG was tested with success and no side effects. A single cup of green tea contains approximately 100mg of EGCG, which is about 8 cups of tea. Most laboratory evaluations suggest more EGCG equals to greater fat reduction, yet some professionals warn that large dose of isolated ingredient from herbs could be a problem. It is not easy to come to an absolute conclusion based on lab studies, yet numerous researchers are suggesting 300mg of EGCG is a proper amount to consume on a daily basis. There are actually dependable clinical results with the amount 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.
