Do Green Tea Supplements Cause Any Side Effects?

By Robert Neely


Talk shows and medical magazines have been advertising green tea extract as a great supplement for fat reduction. With the growing interest of tea, many are concerned about the safeness of the supplement. Many of the press promoting the benefits of tea are not identifying enough of the negative effects. Thoroughly understanding the potential side effects is crucial in order to take health rewards with no damaging outcomes.

Just like many dietary supplements or medicines, the amount has an important role with regards to negative effects. If consumed without care, even the most natural supplement triggers unexpected reactions. Same logic applies here. What exactly is the safe amount of tea?

Some of the most active contents of tea are caffeine and catechin. Both help with using body fat as the resource to create heat which is known as thermogenesis. This procedure in return boosts metabolism. Enhanced metabolic function burns body fat much faster in the human body.

There have been countless experiments on caffeine and how it affects human body. Many experts are saying in most cases above 500mg of caffeine a day is too much. It could be unsafe causing side effects like insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health experts furthermore agree that level of sensitivity to caffeine varies by an individual, however 300mg or less is regarded a healthy dose.

A cup of tea possesses about 20mg of caffeine. Compare to coffee, it is not a lot. A cup of coffee possesses about 100mg of caffeine. If tea is the only caffeinated drink consumed then it should not be a concern. However when other caffeinated drinks are consumed during the day, then it is critical to look at the entire daily amount of caffeine.

Researchers carried out laboratory tests regarding dosage. A daily dosage of 800mg of EGCG has been tested successfully and with no uncomfortable side effects. A cup of green tea has about 100mg of EGCG, which is about 8 cups of green tea. A lot of laboratory tests suggest more EGCG means greater fat burning, however some health professionals agree that an excessive amount of one ingredient from herbs could be problematic. It is not easy to make an absolute conclusion based on lab studies, still numerous health experts are claiming 300mg of EGCG is an ideal dosage to take in a day. There have been good clinical outcomes with the amount of 300mg against cancer cells and weight loss.

Due to the growing interest in green tea, even more laboratory tests will be conducted. For now, 300mg seems to be a safe dosage for both caffeine and EGCG.
