Can You Drink Kombucha When Breastfeeding?
Written by Jordan Morley · Reviewed against NHS: food and drinks to avoid when breastfeeding · Last updated 28 October 2026
We found no UK guidance on kombucha while breastfeeding. It is made from tea, so it can contain caffeine, and it can contain a small amount of alcohol, so the NHS breastfeeding advice on caffeine and alcohol applies. Check the label for pasteurisation and alcohol.
What the guidance says
The NHS foods-to-avoid and breastfeeding pages we read do not mention kombucha. Kombucha is fermented sweet tea, so it can contain caffeine and a small amount of alcohol; the amounts vary by brand, so read the label. Count it towards your caffeine and alcohol limits, and choose a labelled, pasteurised brand if you are unsure. See our pregnancy page for what UK shelf labels say.

Common questions
Is kombucha safe while breastfeeding?
We found no UK guidance on kombucha while breastfeeding. It is made from tea, so it can contain caffeine, and it can contain a small amount of alcohol, so the NHS breastfeeding advice on caffeine and alcohol applies. Check the label for pasteurisation and alcohol.
Does kombucha have caffeine?
Usually, a little, since it's made from tea. Check the label and count it towards 300mg a day.
Is home-brewed kombucha OK?
It can contain more alcohol and variable bacteria. Commercial pasteurised brands are the more predictable choice.
Was this different during pregnancy?
Yes. In pregnancy our verdict was “avoid”, because of a risk to the unborn baby (see our pregnancy guide). Those reasons ended when your baby was born.
What should I avoid while breastfeeding?
The NHS list is short. Caffeine: try not to have more than 300mg a day (a mug of filter coffee is about 140mg, instant 100mg, tea 75mg). Alcohol: it is safer not to drink, but 1 or 2 units once or twice a week should be fine. Oily fish: no more than 2 portions a week. Shark, swordfish and marlin: no more than 1 portion a week. Peanuts are fine unless you're allergic. Most other foods that were off the menu in pregnancy, such as soft cheese, pâté, cured meat and runny eggs, are not restricted.
