An 8-ounce (230-ml) cup of green tea contains between 30 and 50 mg of caffeine.

The recommended maximum amount of caffeine per day is 400 mg, which is the equivalent to around 8 cups of green tea.

However, it’s best that you don’t drink 8 cups at one time, especially if you are sensitive to caffeine.

Overall, green tea is a nutritious beverage that contains safe amounts of caffeine.

Best of all, drinking it may even have some great benefits for your health.
