Can You Drink Kombucha While Pregnant?

Medically Reviewed by Katelyn Holt RN, BSN, BC
Kombucha during pregnancy has four potential concerns: alcohol, caffeine, acidity, and contamination.

Are you a huge kombucha fan, but are wondering if it’s safe to drink now that you’re pregnant?

We’ve all heard of avoiding raw fish, alcohol, and soft cheeses during pregnancy, but what about kombucha? Is it harmful? Or, could it possibly even be beneficial?

In this article, we’ll talk about what kombucha is, and discuss whether it is safe or not to consume kombucha during pregnancy and breastfeeding.

What is Kombucha?

Kombucha is a probiotic-rich beverage fermented by bacteria and yeast and brewed with black or green tea and sugar. Many times, fruit juices or other flavors are added during the brewing process to make its tart taste a little more palatable.

While this potent drink may seem like a new health fad, it has been consumed for thousands of years in Asian cultures.

It has only recently become popular in the U.S. within the past decade.

But you can now find it strolling the aisles of most health food stores, even some gas stations, and Targets! Kombucha is not something you should try for the first time when you are pregnant, always talk to your health care provider before starting something new.

Is Kombucha Safe to Drink During Pregnancy or Breastfeeding?

While kombucha may offer some potential health benefits, there are four main points you should keep in mind before consuming it while pregnant or nursing.

  1. Kombucha Contains Caffeine: Because kombucha is brewed with black or green tea, it does contain some caffeine.
  2. Kombucha Contains Alcohol: Kombucha possesses a trace amount of alcohol, as this is a natural byproduct of the fermentation process. Alcohol could potentially compromise the health of your growing baby (1).
  3. Kombucha Is Unpasteurized: Pasteurization is a method of heat processing beverages and food to kill harmful bacteria. The FDA recommends avoiding unpasteurized products during pregnancy.
  4. Could Be Contaminated: It is possible for kombucha to become contaminated with harmful pathogens, especially when being brewed at home.

The Consensus

It may be best to avoid kombucha during pregnancy and breastfeeding because of its caffeine content, risk,  small alcohol content,  lack of pasteurization, and potential risk of contamination.

A Few Words of Caution

If you are going to drink kombucha while pregnant or breastfeeding, there are a few precautions you should take:

  1. Limit your intake: As little as 4 ounces of commercial kombucha can be safe and effective for pregnant and nursing moms. Too much kombucha could cause dehydration, bloating, heartburn, and insomnia, as resources on kombucha point out.
  2. Avoid alcoholic versions: The alcohol content in kombucha can vary widely, so be sure to check the label before you swig. If you get carded at checkout, you need to find a different brand. GT’s Enlightened is a good one to stick with when pregnant or nursing.
  3. Stay hydrated: Staying hydrated is critical when you’re pregnant or breastfeeding, and especially more if you’re drinking kombucha. If you’re dehydrated, toxins could come out of you and go straight to your baby through your breastmilk or placenta. Mix a few ounces of kombucha with water to gain all the benefits with extra hydration.
  4. Watch for side effects: You could be more sensitive to the ingredients now that you’re expecting, so be sure not to drink more than a few ounces at a time. And while kombucha is great for boosting your energy and relieving constipation, this could pass on to your breastfeeding baby and cause loose stools and sleeping troubles (2).
