Yes, it is safe to drink green tea when consumed in moderate amounts as it will not have any side effects on the baby. Though there is little scientific evidence backing this claim, the American Academy of Pediatrics (AAP) supports it (1).

However, you must select green teas that contain only tea and no other ingredients. The effects of the added herbs in herbal green teas are unknown and could be adverse to an infant. Bottled green tea is also safe during the early days of motherhood as long it is only tea without artificial additives. Sticking to plain green tea is the best way to enjoy the beverage when you are breastfeeding. But, it does not mean that you can drink a cup every hour.

How Much Green Tea Is Safe When Breastfeeding?

Only two cups per day, with each cup of about 237ml, is safe. Green tea is rich in several antioxidants and helps in detoxification, but it also contains caffeine. There is about 29mg of caffeine in a single cup (237ml) while the daily caffeine allowance (from all beverages) during lactation must not be more than 700mg (2). Experts suggest staying way under the upper limit and limiting the consumption of any caffeinated beverage (including green tea) to two cups a day.

Keep in mind that you could be consuming other caffeinated foods such as chocolate, coffee, and soda. Therefore, you will have to adjust your green tea intake in such a way that the total caffeine intake from multiple sources does not exceed the permissible limits.

Exceeding the limits could harm your baby.
