Should Drinkers Be Concerned With Green Tea Side Effects?

By Joseph Scott


TV programs and medical periodicals have been advertising green tea extract as a reliable supplement for weight loss. With the expanding interest of tea, many people are concerned with the safety aspects of the supplement. Many of the press promoting the benefits of tea are usually not explaining enough of the negative effects. Thoroughly knowing the potential negative effects is essential to be able to take health benefits without any damaging consequences.

Similar to many supplements or medicines, the amount plays a vital role when it comes to adverse effects. If consumed without care, even the most organic supplement results in unanticipated reactions. Identical reasoning applies here. So what is the right amount of tea?

A couple of active elements of tea are caffeine and catechin. Both of them assist with using fat as the resource to produce heat which is called thermogenesis. This process in return enhances metabolic function. Increased metabolism burns body fat much faster within the body.

A lot of analyses on caffeine and its impact on human body have been conducted. Numerous experts are saying normally above 500mg of caffeine in a day is too much. It can be harmful causing adverse reactions like insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Researchers furthermore agree that sensitivity to caffeine ranges by an individual, however 300mg or less is regarded a risk-free amount.

A single cup of tea has roughly 20mg of caffeine. It is a small amount. A single cup of coffee has roughly 100mg of caffeine. If tea is the only caffeinated drink taken then it should not be an issue. However if other caffeinated beverages are consumed during the day, then it is important to check the combined daily dosage of caffeine.

Industry experts carried out lab tests concerning dosage. A daily amount of 800mg of EGCG was successfully tested without unintended effects. One cup of green tea has close to 100mg of EGCG, which is 8 cups of green tea. Many laboratory experiments claim more EGCG equals to more fat burning, yet some health specialists advise that large amount of one compound from herbal products could be a problem. It is challenging to come to a definite conclusion based on clinical reports, still a good number of experts are saying 300mg of EGCG is an ideal dose to take in a day. There have been successful laboratory tests using the dosage of 300mg against cancer cells and weight reduction.

Due to the increasing interest in green tea, even more lab tests are going to be conducted. As for now, 300mg appears to be a good amount for both caffeine and EGCG.
