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

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 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.

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.

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.
