Are There Any Side Effects With Green Tea?


By Tom Nelson



Health television shows and periodicals are promoting tea as a beneficial supplement for weight reduction. With the raising interest of tea, a lot of people are concerned with the safeness of the supplement. Many of the press supporting the advantages of tea are not explaining enough of the side effects. Thoroughly understanding the possible side effects is important to be able to take health rewards with no undesirable outcomes.

Similar to numerous dietary supplements or medications, the amount plays a vital role with regards to negative effects. If consumed without careful attention, even the most organic supplement results in unexpected effects. Similar logic is true here. What exactly is the right amount of tea?


A couple of active components of tea are caffeine and catechin. Both of them help out with taking fat as the source to produce heat which is called thermogenesis. This procedure in return raises metabolism. Enhanced metabolic rate burns fat more rapidly in the body.

There were countless experiments on caffeine and how it impacts human body. Lots of specialists are claiming in most cases more than 500mg of caffeine per day is too much. It could be unsafe causing unwanted effects which include insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Experts furthermore acknowledge that responsiveness to caffeine differs by an individual, however 300mg or below is considered a risk-free amount.

In a single cup of tea, there are around 20mg of caffeine. It is not a lot. A cup of coffee possesses about 100mg of caffeine. If tea is the only caffeinated drink taken then it should not be an issue. However when other caffeinated drinks are consumed during the day, then it is important to check the combined daily dosage of caffeine.

There also have been a few tests concerning dosage. A daily amount of 800mg of EGCG was successfully tested without any uncomfortable side effects. A cup of green tea includes roughly 100mg of EGCG, which is about 8 cups of tea. Lots of lab evaluations indicate more EGCG implies greater fat burning, but some medical experts agree that too much of one substance from herbs might be a problem. It is hard 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 successful lab tests with the amount of 300mg versus cancer cells and weight reduction.

Due to the growing interest in green tea as a weight loss aid, additional tests will be conducted. As for now, 300mg appears to be a ideal dose for both caffeine and EGCG.
