Television shows and medical magazines have been marketing tea as a good supplement for weight loss. Because of the growing interest of tea, many people are concerned about the safety aspects of the supplement. A lot of the media promoting the advantages of tea are usually not explaining enough of the negative effects. Thoroughly knowing the possible negative effects is important to be able to take benefits without having unwanted consequences.

Much like a lot of supplements or prescription drugs, dosage provides a vital role in relation to side effects. If consumed without careful attention, even the most healthy supplement will cause surprising effects. Identical reasoning is applicable here. Just what exactly is the proper amount of tea?

Some of the most active contents of tea are caffeine and catechin. Both help with using body fat as the resource to create heat which is known as thermogenesis. This procedure in return boosts metabolism. Enhanced metabolic function burns body fat much faster in the human body.

There have been countless experiments on caffeine and how it affects human body. Many experts are saying in most cases above 500mg of caffeine a day is too much. It could be unsafe causing side effects like insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health experts furthermore agree that level of sensitivity to caffeine varies by an individual, however 300mg or less is regarded a healthy dose.

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 if other caffeinated drinks are consumed throughout the day, then it is critical to check the total daily dosage of caffeine.

Industry experts carried out tests regarding dosage. A daily amount of 800mg of EGCG has been tested with success and with no unwanted effects. A cup of green tea comes with around 100mg of EGCG, which is about 8 cups of green tea. A lot of lab experiments claim more EGCG equals to greater fat reduction, but some professionals advise that large amount of one substance from herbs could be a problem. It is not easy to make a definite conclusion based on lab studies, but a lot of medical experts are saying 300mg of EGCG is an ideal dose to take on a daily basis. There are successful scientific tests with the amount of 300mg against cancer cells and weight reduction.

With the increasing interest in green tea as a weight loss aid, even more tests will be conducted. For the time being, 300mg seems to be a good dose for both caffeine and EGCG.
