Can You Drink Kombucha While Pregnant?
It's best to skip kombucha in pregnancy — it contains some alcohol and caffeine, and raw (unpasteurised) kinds can carry bacteria.
The full answer
Kombucha stacks up several small pregnancy concerns at once. It's fermented, so it contains a trace of alcohol (sometimes more in home-brewed or long-fermented batches), and there's no safe known level of alcohol in pregnancy. Raw (unpasteurised) kombucha carries a small risk of harmful bacteria. And because it's made from tea, it contains caffeine that counts toward your daily limit. None of these is dramatic on its own, but together they're why many providers suggest avoiding kombucha, especially home-brewed kinds. If you really want a fermented fizzy drink, a pasteurised, clearly alcohol-free option is the safer bet — but check with your provider.
Safer alternatives
- Prefer pasteurised, clearly labelled alcohol-free versions if you have any
- Avoid home-brewed or long-fermented kombucha (higher, unknown alcohol)
- Count its tea-based caffeine toward your <200 mg/day limit
When to avoid: Best avoided overall in pregnancy — particularly raw/unpasteurised or home-brewed kombucha.
Kombucha by trimester
| Stage | What changes |
|---|---|
| First trimester | Two issues: raw (unpasteurised) kombucha can carry bacteria, and fermentation produces some alcohol. Both are reasons guidance tends to advise against it in pregnancy. |
| Second trimester | Unchanged. Home-brewed kombucha is the more uncertain version, since the alcohol content and hygiene are less controlled than commercial production. |
| Third trimester | Same position. Pasteurised commercial versions exist and are a different question, but the label needs to say so. |
Common questions about kombucha in pregnancy
Is kombucha safe during pregnancy?
It's generally advised against. Raw (unpasteurised) kombucha raises the same concerns as other unpasteurised products, and fermentation produces some alcohol. Commercially pasteurised versions are a different matter — check the label.
How much alcohol is in kombucha?
Typically a small amount, but it varies with fermentation and is higher in home-brewed batches. Since guidance advises avoiding alcohol in pregnancy, an unpredictable trace amount is the reason it comes up.
What's a good alternative?
Sparkling water with fruit, or a pasteurised soft drink, if it's the fizz and the tartness you want. If it's the gut-health angle, yoghurt with live cultures made from pasteurised milk covers it without the questions.
