How Safe Is Green Tea As A Daily Supplement?

By Robert Neely


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?

The most active substances of tea are caffeine and catechin. Both help with using fat as the source to make heat which is known as thermogenesis. This process in return increases metabolic rate. Accelerated metabolism burns body fat much faster in the body.

Many analyses on caffeine and its effect on human body have been carried out. Many experts are claiming in general above 500mg of caffeine in a day is too much. It can be harmful resulting in side effects which include insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health specialists furthermore agree that sensitivity to caffeine ranges by an individual, however 300mg or below is regarded as 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 if other caffeinated drinks are consumed throughout the day, then it is critical to check the total daily dosage of caffeine.

Researchers carried out laboratory tests regarding dosage. A daily dosage of 800mg of EGCG has been tested successfully and with no uncomfortable side effects. A cup of green tea has about 100mg of EGCG, which is about 8 cups of green tea. A lot of laboratory tests suggest more EGCG means greater fat burning, however some health professionals agree that an excessive amount of one ingredient from herbs could be problematic. It is not easy to make an absolute conclusion based on lab studies, still numerous health experts are claiming 300mg of EGCG is an ideal dosage to take in a day. There have been good clinical outcomes with the amount of 300mg against cancer cells and weight loss.

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.
