Is there caffeine in green tea

Yes, green tea does contain caffeine, although the amount can vary depending on factors such as the specific type of green tea, brewing time, and water temperature. Generally, one cup of green tea contains around 20-45 milligrams of caffeine, which is significantly less than the amount found in a typical cup of coffee.

Caffeine is a natural component of tea and contributes to its stimulating effects. However, green tea is also known for containing L-theanine, an amino acid that can have a calming effect and work in harmony with the caffeine to provide a more balanced and sustained energy boost compared to coffee.
