Health television programs and publications have been marketing green tea extract as a beneficial supplement for losing weight. Because of the expanding interest of tea, a lot of people are questioning the safety aspects of the supplement. A lot of the press supporting the benefits of tea is usually not explaining enough of the unwanted effects. Fully knowing the possible negative effects is crucial in order to take health rewards without any damaging results.

Similar to many supplements or medicines, the amount has an important role with regards to negative effects. If taken without caution, even the most natural supplement allows surprising effects. Similar logic is applicable here. So what is the ideal amount of tea?

The most active substances of tea are caffeine and catechin. Both of them help with using fat as the supply to generate energy which is known as thermogenesis. This process in return boosts metabolic rate. Enhanced metabolic process burns body fat more rapidly in the body system.

There were countless scientific tests on caffeine and how it influences human body. A lot of industry experts are saying usually greater than 500mg of caffeine per day is too much. It can be unhealthy causing unwanted effects which include insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Industry experts furthermore acknowledge that sensitivity to caffeine differs by an individual, however 300mg or below is regarded as a low risk amount.

A cup of tea has approximately 20mg of caffeine. It is not a lot. In a cup of coffee there are approximately 100mg of caffeine. If tea is the only caffeinated beverage taken then it should not be a concern. However if other caffeinated drinks are consumed during the day, then it is critical to consider the total daily dosage of caffeine.

Tea researchers conducted lab tests related to the amount of tea. A daily dose of 800mg of EGCG has been tested with success and no negative effects. A single cup of tea contains around 100mg of EGCG, which is around 8 cups of tea. Lots of laboratory experiments indicate more EGCG means greater fat burning, yet some professionals advise that large quantity of isolated element from herbal plants can be a problem. It is difficult to make an absolute conclusion based on clinical research, still a great number of health professionals are stating 300mg of EGCG is an ideal dosage to consume on a daily basis. There are successful scientific studies using the dose of 300mg fighting cancer cells and weight reduction.

Because of the growing use of green tea as a fat burning aid, even more lab tests will likely be conducted. For the time being, 300mg seems to be an ideal dosage for both EGCG and caffeine.
