What Are The Facts About Negative Effects Of Green Tea?

By Anna Burns


Health television shows and journals have been promoting green tea extract as an effective supplement for weight reduction. Because of the expanding curiosity of tea, a lot of people are wondering the safety aspects of the supplement. A majority of the press promoting the benefits of tea are usually not discussing enough of the side effects. Thoroughly knowing the possible side effects is vital in order to take benefits with no undesirable results.

Much like many dietary supplements or prescription drugs, the amount has an important role with regards to side effects. If consumed without care, even the most healthy supplement results in unanticipated effects. Identical reasoning is true here. Exactly what is the right 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.

There were a lot of experiments on caffeine and how it impacts human body. Many health specialists are stating typically beyond 500mg of caffeine per day is too much. It could be harmful resulting in side effects like insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Industry experts also acknowledge that level of responsiveness to caffeine varies by an individual, however 300mg or lower is considered a risk-free dose.

Within a cup of tea, there are around 20mg of caffeine. Compare to other caffeine containing drinks, it is not much. Within a cup of coffee there are around 100mg of caffeine. If tea is the only caffeinated beverage taken then it should not be an issue. However if additional caffeinated beverages are consumed throughout the day, then it is critical to look at the overall daily amount of caffeine.

There also have been a few lab tests regarding the amount of tea. A daily dose of 800mg of EGCG has been tested successfully and with no unwanted side effects. A cup of tea includes approximately 100mg of EGCG, which is 8 cups of green tea. A lot of clinical experiments suggest more EGCG means more fat burning, but some professionals warn that too much of one compound from herbs may be problematic. It is difficult to make a definite conclusion based on clinical studies, yet a lot of health experts are stating 300mg of EGCG is a safe dosage to take on a daily basis. There are actually reliable laboratory outcomes using the dose of 300mg against cancer cells and weight loss.

Because of the increasing curiosity about green tea, additional laboratory tests are going to be done. In the meantime, 300mg appears to be a good dosage for both caffeine and EGCG.
