Monitoring caffeine intake while breastfeeding
Green tea contains caffeine. That is why, just like pregnant women, breastfeeding mothers should monitor their intake. When consumed in excessive amounts, caffeine passes into breast milk and can be ingested by the baby.
Did you know?
Theine and caffeine are actually the exact same molecule, but they do not act on our body in the same way. Why is that?
- A cup of tea contains less caffeine than a cup of coffee. In other words, a cup of tea is less stimulating than a cup of coffee.
- Even though they come from the same molecule, the body does not assimilate them in the same way. Caffeine is “bioavailable”, meaning it is immediately accessible and passes very quickly into the bloodstream, whereas the caffeine in tea is released gradually over time. This is why coffee is said to give a quick rush, while tea provides sustained stimulation.
- Finally, tea contains a very specific amino acid called L-theanine, which is believed to act on anxiety. Combined with caffeine, it is thought to be responsible for the “energised calm” so often associated with tea, and is found exclusively in this beverage. Perfect for reducing mental and physical stress!
Let us remember that every person is unique and has a different tolerance and sensitivity to caffeine. The effects mentioned above may not necessarily be experienced by everyone.
How many cups of green tea per day while breastfeeding?
It is difficult to state exactly how much caffeine a cup of green tea contains. Indeed, the caffeine level varies from one tea to another depending on the specific characteristics of its cultivation (the leaf harvesting season and their bud content). Furthermore, each person will react differently to caffeine.
The French Agency for Food Safety nevertheless recommends not exceeding 2 to 3 cups of green tea per day while breastfeeding*.
In addition, it is recommended to keep track over the whole day, as this dose of caffeine must be adjusted according to other caffeinated items you consume, such as chocolate, coffee, or fizzy drinks.
There are therefore no contraindications to drinking green tea, provided it is consumed in moderation. A medical reviews is always essential if you have any doubts. Kusmi Tea therefore advises you to consult your GP.
Does drinking green tea reduce breast milk production while breastfeeding?
This question is frequently asked by mothers who wish to breastfeed or are currently breastfeeding their baby. There is no conclusive evidence on the subject. It is known that green tea reduces the body's absorption of plant-based iron due to its high tannin content, but no significant impact has been found regarding iron from meat*. To be completely certain that green tea does not interfere with your daily intake, we recommend enjoying your cup of green tea between meals rather than with them.
Can you drink decaffeinated green tea while breastfeeding?
Yes, the crafting process for this type of green tea reduces its caffeine content. However, please be aware that it still contains residual amounts. Furthermore, this amount varies from one tea to another.

The health benefits of green tea
Green tea offers many health benefits for the body:
- It is rich in antioxidants (catechins and particularly EGCG) that play an important role in protecting the body against certain conditions. Green tea is thought to help combat the effects of free radicals and premature cellular ageing.
- Thanks to L-theanine, green tea is believed to have a soothing effect. This amino acid is thought to act on the brain, resulting in a reduction in mental and physical stress.
Herbal tea and infusions: alternatives to green tea
Herbal teas and infusions also represent a very good alternative for all mothers wishing to reduce or stop their tea consumption while breastfeeding. To find out which flavour and blend to choose, do not hesitate to ask your doctor. They will be able to advise you on galactogenic herbs (fennel, nettle...) and herbal teas specially designed for this period.
There is therefore no contraindication to drinking green tea while breastfeeding, provided you monitor your consumption. It is all a question of moderation! Consuming green tea in sensible amounts presents no danger to the baby, allowing the mother to continue enjoying the benefits of this beverage. If you have any doubts or questions, speak to your doctor.
