Green Tea Extract Side Effects - What Is The Safe Amount?

By Kenneth Palmer

Talk shows and health magazines are promoting green tea as an excellent supplement for weight loss. With the increasing interest of tea, many people are concerned with the safety aspects of the supplement. A lot of the media promoting the advantages of tea are usually not explaining enough of the negative effects. Thoroughly knowing the potential unwanted effects is important to be able to take health benefits with no damaging outcomes.

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.

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.

Industry experts carried out laboratory tests pertaining to the amount of tea. A daily amount of 800mg of EGCG was tested with success and with no uncomfortable side effects. A single cup of tea comes with roughly 100mg of EGCG, which is about 8 cups of green tea. Numerous laboratory experiments indicate more EGCG means more fat burning, yet some health specialists warn that large amount of one element from herbal plants may be a problem. It is challenging to make an absolute conclusion based on lab experiments, still a lot of health specialists are stating 300mg of EGCG is a safe dosage to consume daily. There are actually successful scientific studies using 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.
