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.

Much like a lot of supplements or prescription drugs, dosage provides a vital role in relation to side effects. If consumed without careful attention, even the most healthy supplement will cause surprising effects. Identical reasoning is applicable here. Just what exactly is the proper amount of tea?

An active ingredients of tea are caffeine and catechin. Both help with utilizing body fat as the source to produce energy which is known as thermogenesis. This process in return enhances metabolic rate. Increased metabolic process burns fat more rapidly in the human body.

Many analyses on caffeine and its effect on human body have been carried out. Many experts are claiming in general above 500mg of caffeine in a day is too much. It can be harmful resulting in side effects which include insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health specialists furthermore agree that sensitivity to caffeine ranges by an individual, however 300mg or below is regarded as a good amount.

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.

With the increasing interest in green tea as a weight loss aid, even more tests will be conducted. For the time being, 300mg seems to be a good dose for both caffeine and EGCG.
