How Serious Are 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.

As with countless dietary supplements or prescription drugs, dosage provides an important role with regards to adverse effects. If consumed without care, even the most healthy supplement may cause unexpected effects. Similar reasoning can be applied here. Precisely what is the ideal amount of tea?

Two active substances of tea are catechin and caffeine. These two assist with utilizing fat as the resource to generate heat which is known as thermogenesis. This procedure in return speeds up metabolism. Boosted metabolic function burns body fat quicker 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.

There have also been some laboratory tests about dosage. A daily amount of 800mg of EGCG was successfully tested without side effects. A single cup of green tea includes roughly 100mg of EGCG, which is about 8 cups of green tea. Lots of clinical evaluations suggest more EGCG implies greater fat burning, however some health specialists warn that large amount of isolated ingredient from herbal products might be a problem. It is challenging to come to a definite conclusion based on lab tests, yet many researchers are suggesting 300mg of EGCG is a proper dose to take daily. There are actually quality lab outcomes using the dosage of 300mg fighting 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.
