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.

Similar to many supplements or prescription drugs, dosage plays a significant role in terms of side effects. If consumed without care, even the most herbal supplement will cause unanticipated reactions. Identical reasoning can be applied here. So what is the proper amount of tea?

A couple of active contents of tea are catechin and caffeine. These two assist with taking body fat as the supply to make energy which is known as thermogenesis. This procedure in return improves metabolic rate. Enhanced metabolic rate burns body fat much faster in the human body.

Numerous scientific tests on caffeine and its effect on human body system have been done. Lots of health experts are stating usually above 500mg of caffeine per day is too much. It can be unsafe causing adverse reactions which include insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health specialists also agree that level of responsiveness to caffeine differs by an individual, but 300mg or less is regarded a low risk amount.

A single cup of tea carries about 20mg of caffeine. Compare to coffee, it is a small amount. A single cup of coffee carries about 100mg of caffeine. If tea is the only caffeinated drink taken then it should not be a problem. But if other caffeinated beverages are consumed during the day, then it is important to consider the combined daily dose 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.

Due to the increasing interest in green tea as an alternative medicine, much more tests will likely be done. For now, 300mg appears to be a good amount for both EGCG and caffeine.
