Are There Any Side Effects With Green Tea?

,

Daytime talk shows and medical journals are promoting green tea as a reliable supplement for fat reduction. With the raising interest of tea, a lot of people are wondering the safeness of the supplement. A majority of the media promoting the advantages of tea are not discussing enough of the unwanted side effects. Thoroughly understanding the possible unwanted effects is essential in order to take benefits without having unwanted consequences.

As with countless dietary supplements or medications, the amount plays an important role in terms of adverse effects. If taken without caution, even the most herbal supplement allows surprising reactions. Same reasoning applies here. Precisely what is the ideal 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 have been quite a few studies on caffeine and how it affects human body. A lot of health experts are claiming usually beyond 500mg of caffeine a day is too much. It could be unhealthy causing adverse reactions which include insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health specialists also acknowledge that sensitivity to caffeine ranges by an individual, but 300mg or less is regarded a good dosage.

A cup of tea possesses around 20mg of caffeine. Compare to other caffeinated drinks, it is a small amount. In a single cup of coffee there are around 100mg of caffeine. When tea is the only caffeinated beverage taken then it should not be a concern. However if other caffeinated beverages are consumed throughout the day, then it is important to consider the overall daily amount of caffeine.

Tea researchers carried out laboratory tests about the amount of tea. A daily dosage of 800mg of EGCG was tested with success and with no uncomfortable side effects. One cup of tea possesses roughly 100mg of EGCG, which is 8 cups of tea. A lot of clinical tests indicate more EGCG implies more fat reduction, yet some health specialists warn that a lot of one ingredient from herbal products can be problematic. It is hard to make a definite conclusion based on laboratory studies, yet many health specialists are suggesting 300mg of EGCG is a good dose to consume daily. There are actually safe clinical outcomes using the dose of 300mg against cancer cells and weight reduction.

Due to the increasing use of green tea as a fat burning aid, even more laboratory tests are going to be done. For now, 300mg appears to be a safe amount for both EGCG and caffeine.
