Yes, green tea does contain caffeine. However, the amount of caffeine in green tea is generally lower than that in other caffeinated beverages like coffee or black tea. The amount of caffeine in green tea can vary depending on several factors, such as the type of green tea, the brewing method, and the steeping time, but on average, a cup of green tea contains about 25-30 mg of caffeine. This is compared to about 95 mg in a cup of coffee. So, green tea can provide a mild stimulation and energy boost, but it's still important to be mindful of your caffeine intake, especially if you are sensitive to its effects.
