Pregnancy comes with a long list of food and drink questions, and kombucha is one that trips up a lot of expecting mothers. It seems healthy. It is trendy. People swear by its gut health benefits.
But is it actually safe to drink when you are growing a baby?
The honest answer is complicated. Let us walk through what you need to know so you can make an informed decision.
What Is Kombucha, Exactly?
Kombucha is a fermented tea that has been around for centuries. It starts as sweetened tea - usually black tea or green tea - and is then fermented using a symbiotic culture of bacteria and yeast, commonly known as a SCOBY.
The fermentation process is what gives kombucha its fizzy, slightly sour taste. During fermentation, the culture of bacteria and yeast breaks down the sugar in the tea and produces acids, gases, and yes, small amounts of alcohol and caffeine. That combination is exactly what raises concerns for people who are pregnant.
The Key Concerns Associated With Kombucha During Pregnancy
Alcohol Content
Here is the part that surprises most people. Kombucha contains alcohol. Not a lot, but it is there.
Most store-bought kombucha products are labeled as non-alcoholic because they contain less than 0.5 percent alcohol by volume (ABV). That is the legal threshold in the United States for a beverage to be classified as a non-alcoholic drink.
The amount of alcohol in a standard bottle of kombucha is generally low, but it is not zero. The alcohol content of kombucha can also vary. Homemade or home-brewed kombucha can have significantly higher ABV levels because there is no regulated fermentation cutoff; some homebrews have reached alcohol levels similar to low-alcohol beer.
The American College of Obstetricians and Gynecologists has made it clear that no amount of alcohol during pregnancy is considered safe. Even small, repeated exposures carry the risk of contributing to fetal alcohol spectrum disorder. This is why the alcohol and caffeine content in kombucha matters, even if the numbers seem small on their own.
Caffeine Content
The caffeine in kombucha comes from the tea it is brewed from. Black tea and green tea both naturally contain caffeine. The fermentation process does reduce some of it, but it does not eliminate caffeine entirely.
The amount of caffeine in a typical serving of kombucha is less than what you would find in a cup of coffee, but it still contributes to your total daily caffeine intake. Most healthcare guidelines recommend limiting caffeine intake to under 200 milligrams per day during pregnancy. If you are already drinking decaf coffee or other beverages with trace caffeine, that bottle of kombucha adds up.
Unpasteurized Bacteria
Most commercial kombucha is unpasteurized. Pasteurization kills harmful bacteria through heat, but it also kills the live and active cultures that make kombucha appealing in the first place. Many kombucha manufacturers skip pasteurization specifically to preserve the probiotic content.
The problem is that unpasteurized drinks can carry harmful bacteria like Listeria and Salmonella.
Pregnant women have a weakened immune response, which makes them more vulnerable to foodborne illness. Listeria in particular is dangerous during pregnancy and has been linked to miscarriage, preterm labor, and serious complications for the fetus. This is the same reason pregnant women are told to avoid unpasteurized milk and certain soft cheeses.
Is Kombucha Safe During Pregnancy?
Most healthcare providers recommend that pregnant women avoid kombucha entirely, or at least approach it with serious caution. The combination of alcohol content, caffeine, and unpasteurized bacteria creates a risk profile that is hard to justify, especially when safer alternatives exist.
That said, not every sip of kombucha will automatically cause harm. The risks of drinking kombucha during pregnancy are more about consistent exposure and cumulative effect. But because no safe threshold has been established for alcohol during pregnancy, most doctors recommend skipping it.
If you are asking whether kombucha is safe to drink while pregnant, the straightforward answer is: it is not recommended. For kombucha to be considered safe during pregnancy, it would need to be pasteurized, have verified near-zero alcohol, and contain minimal caffeine. Most products on the shelf do not meet all three of those criteria.
Homemade kombucha is an even clearer no. Without controlled fermentation and lab testing, you cannot know the exact ethanol level or whether harmful bacteria have contaminated the batch.
What About Kombucha and Breastfeeding?
If you are wondering about kombucha after delivery, the same concerns apply when you breastfeed. Alcohol and caffeine both pass into breast milk. While the amounts may be small, it is still worth discussing with your healthcare provider before adding kombucha back into your routine postpartum.
Pregnancy-Safe Alternatives to Kombucha
If you love the fizzy, tangy quality of kombucha, there are options that are similar to kombucha but better suited for pregnancy.
- Water kefir - a fermented drink made from water, sugar, and kefir grains, typically lower in alcohol and available pasteurized
- Ginger-based drinks - ginger is known to help with nausea and can be found in alcohol-free, caffeine-free sparkling forms
- Fruit spritzers - sparkling water mixed with 100 percent fruit juice, like apple or other fruit blends, offers a fizzy fix without any fermentation risk
- Pasteurized probiotic drinks - some brands offer gut-health-focused beverages that are pasteurized and formulated to be pregnancy-safe
These options let you support your gastrointestinal tract without the risks that come with unpasteurized, fermented foods and drinks.
Supporting Gut Health During Pregnancy the Smarter Way
Gut health matters during pregnancy. Your digestion changes, nausea can make eating difficult, and your body is working harder than ever. The appeal of kombucha makes sense in that context. But there are safer, more consistent ways to support your nutrition and wellness during this time.
Storkling was built with exactly this challenge in mind.

It sidesteps the pill-swallowing struggle entirely and fits into a daily routine without the uncertainty that comes with fermented beverages.
Conclusion
Kombucha during pregnancy raises real concerns around alcohol, caffeine, and unpasteurized bacteria - none of which are worth gambling with. Most providers recommend that pregnant women avoid kombucha and seek safer alternatives instead. If you are looking for a gut-friendly, nausea-friendly way to support your health while pregnant, explore what Storkling has to offer.
