What Are The Facts About Negative Effects Of Green Tea?

By Anna Burns


TV shows and health periodicals have been advertising green tea extract as an excellent supplement for fat loss. With the raising interest of tea, a lot of people are questioning the safeness of the supplement. A lot of the media supporting the benefits of tea are usually not identifying enough of the unwanted effects. Fully knowing the possible side effects is crucial in order to take health benefits with no harmful outcomes.

Much like countless dietary supplements or medicines, dosage has an important role with regards to unwanted effects. If consumed without careful attention, even the most organic supplement will cause unexpected reactions. Identical reasoning is true here. Exactly what is the safe amount of tea?

A couple of active elements of tea are catechin and caffeine. These two help with utilizing fat as the source to make energy which is called thermogenesis. This procedure in return increases metabolism. Enhanced metabolic process burns fat more rapidly in the body system.

Various experiments on caffeine as well as its influence on human body have been conducted. Lots of health specialists are claiming in most cases above 500mg of caffeine in a day is too much. It can be harmful resulting in negative effects which include insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health specialists also acknowledge that level of responsiveness to caffeine varies by an individual, but 300mg or less is regarded as a good amount.

In a single cup of tea, one can find approximately 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. When tea is the only caffeinated beverage consumed then it should not be an issue. But if additional caffeinated beverages are consumed during the day, then it is important to check the entire daily amount of caffeine.

There have also been a few tests regarding the amount of tea. A daily dose of 800mg of EGCG was successfully tested without uncomfortable side effects. A cup of green tea contains approximately 100mg of EGCG, which is 8 cups of green tea. Numerous lab tests claim more EGCG equals to greater fat loss, however some health specialists warn that too much of isolated ingredient from herbal plants can be problematic. It is challenging to come to a definite conclusion based on clinical research, but many health experts are stating 300mg of EGCG is a safe amount to take daily. There have been successful lab experiments while using the dose of 300mg fighting cancer cells and weight loss.

Because of the growing popularity of green tea, much more laboratory tests will likely be done. For the time being, 300mg appears to be an ideal dosage for both EGCG and caffeine.
