What Are Green Tea Extract Side Effects?

By Kenneth Palmer


Health television programs and journals are promoting green tea extract as an excellent supplement for weight reduction. Because of the expanding curiosity of tea, many people are questioning the safeness of the supplement. A lot of the presses supporting the benefits of tea are not explaining enough of the side effects. Fully understanding the potential negative effects is vital to be able to take health rewards without having damaging 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 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.

A lot of scientific studies on caffeine and its influence on human body have been conducted. Many health specialists are saying in most cases above 500mg of caffeine in a day is too much. It can be unhealthy causing negative effects such as insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health experts furthermore agree that level of sensitivity to caffeine differs by an individual, but 300mg or lower is regarded a risk-free dosage.

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.

There also have been a number of laboratory tests about dosage. A daily amount of 800mg of EGCG was successfully tested without any negative effects. A single cup of tea possesses roughly 100mg of EGCG, which is 8 cups of tea. Most lab evaluations suggest more EGCG implies greater fat reduction, yet some medical experts advise that large quantity of isolated compound from herbs may be a problem. It is hard to make an absolute conclusion based on laboratory research, yet numerous medical experts are saying 300mg of EGCG is the best dosage to consume in a day. There are actually successful lab experiments with the dosage 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.
