Green Tea Side Effects - Understanding Dosage
Like numerous dietary supplements or medicines, dosage provides an important role in terms of side effects. If consumed without care, even the most healthy supplement results in surprising reactions. Same reasoning can be applied here. Precisely what is the ideal amount of tea?
Two active components of tea are catechin and caffeine. Both help with taking body fat as the resource to produce heat which is known as thermogenesis. This process in return boosts metabolism. Increased metabolic rate burns body fat faster in the body.
Various experiments on caffeine and its effect on human body system have been performed. Numerous nutritionists are claiming typically greater than 500mg of caffeine in a day is too much. It can be damaging resulting in negative effects like insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. Health experts furthermore acknowledge that responsiveness to caffeine differs by an individual, but 300mg or lower is considered to be a low risk amount.
In a cup of tea, there are about 20mg of caffeine. Compare to other caffeinated drinks, it is not a lot. In a cup of coffee there are about 100mg of caffeine. If tea is the only caffeinated beverage consumed then it should not be an issue. However if other caffeinated drinks are consumed throughout the day, then it is important to look at the overall daily dosage of caffeine.
There also have been some tests regarding the amount of tea. A daily dosage of 800mg of EGCG was successfully tested with no side effects. A cup of green tea comes with about 100mg of EGCG, which is 8 cups of green tea. A lot of lab tests suggest more EGCG equals to more fat burning, but some experts agree that too much of isolated substance from herbs can be problematic. It is hard to come to a definite conclusion based on lab research, but numerous experts are stating 300mg of EGCG is a proper amount to take on a daily basis. There are actually dependable lab results with the dose of 300mg against cancer cells and weight reduction.
Because of the raising use of green tea as an alternative remedy, a lot more tests will be done. In the meantime, 300mg appears to be a safe dose for both EGCG and caffeine.
