Can I drink kombucha while pregnant?
Kombucha is fermented tea. Its reputation as a health drink does not establish that it is suitable during pregnancy.
Short answer
Avoid kombucha during pregnancy, as Mayo Clinic advises. Alcohol from fermentation and possible contamination are concerns, especially with home brewing in unclean conditions. A low-alcohol label alone does not resolve these concerns; choose another drink such as water.
What to check before eating
- Are you choosing an alternative drink, rather than relying on a low-alcohol claim?
- Does your alternative contain alcohol or caffeine?
- If you already drank kombucha, what product, amount and timing can you share with your clinician?

How to choose an alternative drink
Start by choosing a different drink
Follow Mayo Clinic’s advice to avoid kombucha while pregnant. Its caution includes contamination concerns, particularly when home brewing conditions are unclean; checking alcohol alone is not enough.
Guidance sources: Mayo Clinic [4]
Do not turn a threshold into a serving allowance
TTB’s 0.5% alcohol threshold determines alcohol regulation; this regulatory threshold is not a medical safety limit. CDC states that no safe amount of alcohol use during pregnancy is known. A low-alcohol claim is not a reason to override the advice to avoid kombucha.

Count caffeine in your alternative
If choosing coffee or tea instead, ACOG advises keeping total daily caffeine below 200 mg from all foods and drinks. Water is an option without caffeine or alcohol.

Common food and drink questions
Can fermentation continue in the bottle?
Yes. TTB notes that alcohol content may increase after bottling through continued fermentation. Storage instructions are not a guarantee of zero alcohol.

What if I drank some before checking?
A product label cannot predict an individual pregnancy outcome. Stop alcohol use and discuss the product, amount and timing with your prenatal clinician if you are concerned.

Background and other choices
What matters for kombucha
- Mayo Clinic advises pregnant people to avoid kombucha.
- Fermentation can produce alcohol, and alcohol content may rise after bottling.
- Unclean brewing conditions can allow harmful bacteria to grow; alcohol is not the only concern.
Safer next steps
- Choose water or another alcohol-free, non-fermented drink.
- Do not treat home brewing or a low-alcohol label as proof of pregnancy suitability.
- If choosing coffee or tea instead, include its caffeine in your daily total.
What Can I Eat can and cannot confirm
Can I Eat can use the food name, visible label text and details you provide to highlight relevant questions.
