Important Health Risk Information Regarding Green Tea Dosage

By Jonathan Judd


Health related TV shows and periodicals are marketing green tea as a good supplement for weight loss. Because of the increasing interest of tea, a lot of people are concerned with the safety aspects of the supplement. Many of the media supporting the advantages of tea are not explaining enough of the side effects. Thoroughly knowing the possible side effects is crucial to be able to take health rewards with no harmful effects.

Just like a lot of supplements or prescription drugs, the amount has a vital role with regards to negative effects. If taken without care, even the most healthy supplement can cause unexpected effects. Same reasoning is true here. So what is the safe amount of tea?

Two active substances of tea are caffeine and catechin. Both help with using fat as the source to make energy which is known as thermogenesis. This procedure in return increases metabolic function. Enhanced metabolic rate burns fat faster in the body.

There were quite a few studies on caffeine and how it affects human body. Many nutritionists are saying in most cases beyond 500mg of caffeine a day is too much. It can be harmful resulting in unwanted effects like insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Researchers also agree that responsiveness to caffeine ranges by an individual, however 300mg or lower is considered a good amount.

A single cup of tea possesses about 20mg of caffeine. Compare to coffee, it is a small amount. A single cup of coffee possesses about 100mg of caffeine. If tea is the only caffeinated drink taken then it should not be a concern. But when other caffeinated beverages are consumed throughout the day, then it is critical to consider the overall daily amount of caffeine.

There also have been some laboratory tests regarding the amount of tea. A daily dose of 800mg of EGCG was successfully tested without any unwanted effects. A single cup of green tea contains approximately 100mg of EGCG, which is about 8 cups of green tea. Most lab experiments claim more EGCG implies greater fat burning, however some health professionals warn that too much of isolated ingredient from herbs may be problematic. It is challenging to come to a definite conclusion based on laboratory studies, still a good number of researchers are suggesting 300mg of EGCG is an ideal dose to consume daily. There are dependable lab outcomes with the dosage of 300mg versus cancer cells and weight reduction.

Because of the growing availability of green tea as an organic supplement, more lab tests will likely be done. As for now, 300mg appears to be an ideal dose for both EGCG and caffeine.
