Can I eat kombucha while pregnant?

Avoid

Most guidance advises avoiding kombucha during pregnancy — it is unpasteurized, contains trace alcohol, and fermentation can be unpredictable.

Medically reviewed by Dr. Example, OB-GYN, MD Last reviewed: January 15, 2025Editorial process

What's safe

A very small amount (≤ 4 oz) of commercial pasteurized kombucha if your OB-GYN specifically approves
Sparkling water with lemon or fruit as a fizzy alternative
Pasteurized kefir if you want a probiotic-rich drink

What to avoid

Home-brewed kombucha — alcohol content can spike to 3–4% ABV unpredictably
Unpasteurized commercial kombucha (the majority of grocery-store brands)
Kombucha from a tap or self-serve fermenter at a café or health-food store

By trimester

1st Trimester

Most cautious guidance advises avoiding kombucha entirely in the first trimester given uncertain alcohol content and unpasteurized status.

2nd Trimester

If you have a strong craving, consult your OB-GYN before consuming any amount.

3rd Trimester

Continue to avoid or keep to an absolute minimum — ACOG states no amount of alcohol has been proven safe in pregnancy.

Frequently asked questions

How much alcohol is actually in kombucha?

Commercial kombucha is labeled 'non-alcoholic' (< 0.5% ABV), but independent testing has found batches at 1–3% ABV, and home brews can reach higher. ACOG states no amount of alcohol has been proven safe during pregnancy.

Can I drink kombucha for the probiotics instead?

Pasteurized yogurt, pasteurized kefir, and evidence-backed probiotic supplements have a better safety profile during pregnancy. Talk to your provider if gut health or digestive discomfort is a concern.
