Caffeine in Green Tea

People ask me all the time about the caffeine content of different beverages. Some people are really sensitive to caffeine and notice a major change in anxiety and sleep patterns from just a small amount. Others are less sensitive. Both coffee and green tea can be a source of comfort and enjoyment for a lot of people and they both have some health benefits.  

How Much Caffeine is Too Much?

Health Canada recommends that adults limit their intake of caffeine to no more than 400 mg of caffeine daily. This amounts to about 3-4 cups of brewed coffee assuming that each cup is 8 oz. This limit is lower for pregnant people and children/teens. Of course, the caffeine content of a beverage varies widely depending on how it’s prepared.

How Green Tea Compares

Green tea usually has less caffeine than coffee. While 8 oz of brewed coffee can have 95-135 mg of caffeine, 8 oz of green tea has about 30 mg. Decaf coffee is not completely caffeine free but it usually has less than 5 mg per 8 oz. Decaf green tea usually has little to no caffeine.
