Green Tea Side Effects
Caffeine Causes Most Green Tea Side Effects
The side effects of green tea are mostly related to the caffeine it contains. Each cup of green tea has around 40 milligrams of caffeine (a cup of coffee has about 100 milligrams of caffeine). Too much caffeine from green tea may cause side effects such as difficulty sleeping, dizziness, irregular heartbeat, reduced appetite, diarrhea, or headache.
