Does green tea cause jitters

Answer 1

I dont mean this to be insulting, but I presume you are American? Americans have this misconseption that "coffee" has a lot of caffeine in it!. it does have some, but not enough to make people hyperactive. Americans are paranoid about giving coffee to their children, BULL they are better off not giving the children sweets/candy, that makes them hyperactive a lot more. Its something like saying "I am lactose intollerant" that is an American ailment. Nobody outside America is "lactose intollerant". its just something that the doctors say so they can prescribe you with a needless drug that will put more money into the American economy.

Answer 2

Your question is an excellent one, because there is a lot of confusion about the amount of caffeine in green tea.

Although green tea has more caffeine than coffee in its dry form, the average cup of green tea has considerably less caffeine than the average cup of coffee. This is mostly due to the steeping time - the amount of time the tea is in the water - and the lower temperature of the water.

The amount of caffeine in green tea varies by the variety and the preparation, however the average amount of caffeine in an 8 oz. cup is about 25 - 30 mg. The average amount of caffeine in coffee is about 145 mg.

Caffeine is most active in the body 15 minutes to about 2 hours after ingestion. It then has a half-life of anywhere from 4.5 - 6 hours. A person's sensitivity to caffeine is generally a function of body size and weight. However, the amount of caffeine in green tea is relatively low, and it would take a lot of it to cause jitters.

The antioxidants in green tea also have a positive effect on the sympathetic nervous system, so the risk of jitters is even lower than a bottle of soda for example. Add to that the high level of L-theanine in green tea, and it is exceptionally unlikely. L-theanine is an amino acid that crosses the blood-brain barrier and stimulates the production of dopamine that acts on the pleasure centers of the brain to bring about an overall sense of well-being.

So, the short answer is "no" for the vast majority of people.
