Is Kombucha Safe When Pregnant or Nursing?


If you’re a new or expectant mother, you may want to know whether or not it’s safe to drink kombucha when pregnant or nursing.  Ask enough people, and you’ll get a myriad of answers.

Here’s mine: Yes, kombucha is safe when pregnant or nursing. With qualifications.

What are those qualifications?

If you’ve been a regular kombucha drinker, keep drinking it! Kombucha has a lot of benefits for the pregnant mother:

  • It increases energy levels.
  • It helps bowel movements be regular.
  • It detoxifies the body.
  • It helps you maximize nutrient absorption because it’s probiotic.

All those are good things! Pregnant ladies often suffer from lack of energy, and this will give you an energy boost without resorting to caffeine or sugar. Pregnant women also frequently struggle with constipation during pregnancy, and this can help you be more regular. Everyone knows that pregnancy increases mucus production, and this can make battling normal colds or allergies difficult. Kombucha can help cleanse and detox your body safely so you can ward off potential illnesses. And, of course, pregnant women are creating a new little life inside them, so they need to be able to use all the nutrients from their (hopefully) nutrient dense foods.

I do have a couple of cautions for pregnant women, though.

If you’re pregnant and you’ve never drunk kombucha before, use caution. In very rare cases, kombucha can cause a reaction in first time drinkers. It’d be terrible to be one of those rare people and have that reaction while pregnant. If you still choose to try to start drinking kombucha, please do so slowly. Start off drinking as little as 4 oz. a day, then slowly build that up as you ascertain your body’s response to this potent beverage.

Is drinking kombucha safe while nursing?

If you’ve made a safe home brew, the answer again is yes, but be cautious. What is a safe brew? One that is not overly acidic (that might cause acidosis), but is also not so basic that it doesn’t ward off pathogens. Normally, I’d tell you to just go by smell and taste to determine when your brew is done. But when nursing, it’s best not to take any risks. You can use inexpensive pH testing strips to make sure you’re drinking the brew between pH levels 2.5 and 3.0.

Again, I have a couple of cautions for nursing mothers, though.

First, kombucha is a detoxing agent. If you’re well-hydrated, those toxins will come out in your pee or stool. If you’re dehydrated, they can come out through your skin, your eyes, even your breast milk. It’d be terrible to have those toxins going out of you and straight into your baby.  So, stay hydrated!

Second, kombucha increases energy. Whatever you eat or drink, you’re essentially sharing with your baby as you nurse. So while you may profit from increasing your energy levels, you need to ask whether your baby needs an energy increase or not. If the answer is no, don’t drink kombucha. Get your probiotics from kefir, sour cream, fermented foods, or supplements instead.

Third, kombucha makes you more “regular.” While this is incredibly helpful for most adults, who suffer from various kinds of digestive stagnation, it may not be helpful to your baby at all. If you drink kombucha while nursing, watch out for overly-loose stools in your baby. You don’t want to risk dehydrating your little one! Remember, with breastfed babies defining diarrhea isn’t so much about frequency of passing stools (some breastfed babies can pass 12 a day while others manage only one every two or three days!), but about how liquid or explosive they are. You’re the mom; you know what’s normal. If their stools start becoming abnormal when you drink kombucha, lay off it.

All that said, please know that I drank kombucha for years while nursing my sons and never noticed any ill effects. My babies were happy, healthy, had regular naps, etc. And by healthy, I mean healthy. My first son didn’t have his first cold until he was 14 months old, and my second son didn’t have his first cold until he was 12 months old.

Wait a minute! You can brew kombucha at home?

For those of you who want to know how, here’s a tutorial on how to make those tasty flavored kombucha teas at home. If you’re looking to start that process, you can find reliable sources of starter supplies and kombucha “mothers” (symbiotic colonies of bacteria and yeast that start the culture) online here.

      Dan — I haven’t heard any such thing. In fact, I’ve only read cautions about it being too acidic (particularly for young children). Guess that one calls for more research!

    • says

      Dan, that is correct from my understanding. I am trying to find the article now and I can’t remember where it was. But it was about how kombucha, like other fermented foods, supports alkalinity in the body due to the conversion of acids during digestion.

    well i drink GT’s kombucha, store bought. and i did so when it seemed palateable while pregnant and have drank it at least once per week while nursing mynow 1 year old baby. I did drink it for years prior to her conception though. how could drinking kombucha cause acidosis? this sounds a bit extreme, i mean are you talking like gallons per day? thanks for all the good info as always!

    • says

      Emily — Only talking about drinking gallons a day of an over-fermented drink. If you ferment it correctly, I don’t think any one would have any problems.

      • Caylie says

        So my grandpa made some homemade, and wanted me to try it, so I drink maybe a quarter of a cup, I didn’t even think about if it woul be bad for my son or not, this is the first time I have ever done it, so I was wondering if u felt that I shouldn’t breastfeed for a little bit?? And give him formula? Maybe just for a day?? What do u recommend I do?

  2. says

    Great post! As a midwife, I’m often asked this question.It’s a hard one (and complicated to answer!). Nice job. :)
    I’m also one of the founders of a great small-scale magazine called The Birth Project. I was wondering if the author of this post might be interested in letting us reprint this as an article in the spring issue of TBP?

    “It’d be terrible to have those toxins going out of you and straight into your baby. So, stay hydrated!”

    I think it’s a matter of more than just hydration. This is an issue that’s been discussed quite a bit on MDC, and because I personally have amalgam fillings in my mouth and never drank kombucha pre pregnancy or nursing, I am waiting until my ds is weaned to start. I think the risk of me dumping mercury and all sorts of other toxins into him is just too great to be worth the benefits of drinking kombucha for me at the moment. (Here is a thread on MDC with some info on why kombucha may not be perfectly safe while pregnant/nursing:

    Many many many people have detox pathway problems, which can cause those toxins to be released in wonky ways, in places they are not supposed to go to. Doing any kind of detox (including kombucha which I’ve read is a very strong mobilizer of mercury and other metals) while pregnant or nursing can be dangerous IMO b/c if your detox pathways are blocked, those toxins will get released, and because they can’t get out through the correct pathways, they will just circulate through your system and resettle themselves in scary places like your organs, or, if you are pregnant, right into your growing fetus. Breastmilk is a detox pathway, which is why I personally just avoid super detoxing things like kombucha as I wasn’t doing it prepregnancy. I feel I get enough benefits of fermented foods from my kraut, kimchi and non-dairy kefir for now, and don’t think it’s worth the risk for me/my son. I have a very sensitive child w/ food sensitivity issues which is a big part of my reasons for being so cautious, but I think it’s important to look at all possible angles of this issue before adding it in to your pregnancy or nursing diet.

    Just another perspective! 😉 (If you’re interested, check out the allergies, health and healing, and traditional foods forums, along w/ for more info on detox pathways–I certainly don’t know enough about all of this, but have learned sooooo much from those two places.)

    The caffeine in kombucha might be worth considering, too. It plays a role in the energizing nature of kombucha. So if you are limiting your coffee and tea intake because of the caffeine, you might want to limit how much kombucha you drink. Kombucha contains less caffeine than tea, but it is still noticeable.

    Would you please tell me when is a good time to flavor the kombucha drink? Is it when the taste is right to you? Or is it just a day or two before the taste is right to you so that you can bottle it and put flavor at the bottom and let it ferment for another two more days or so.

    This is my first kombucha, so it would be nice to know. I am growing a mother SCOBY but it will take a very long time. I got a mother from someone and started last night, but I was never clear on when is the time to bottle and flavor the kombucha though.

    I hope you can clearify this.



  6. Alex says

    Great info. Thanks.
    I just wanted to add to your description of how a breastfed baby’s diarrhoea might look like. A lot of breastfed babies have very runny, very explosive poos when they are healthy. Mine sure did. No nappy, be it cloth or dosposable could hold that. Especially with my daughter who only did a poo every 5-6 days, but then did 2 or 3 in a row.
    It is the colour and consistency that is a giveaway. If their stool is sort of slimey and looks like it has gelatinous matter in it and has a greenish tinge, then that is a definite sign of diarrheoa.
    You know your baby and his pattern. If it changes all of a sudden after you have introduced a new food/beverage, then use caution.

  7. Amanda says

    Can I give Kombucha to my 21 month old son? I began to drink it a few months ago (and I’m breastfeeding my 4 month old…now I will stop), but I would like to continue to make it if it’s okay for my son to drink…any thoughts?

  8. Kominfo says

    This article makes claims about kombucha that are unfounded through medical trials and dispenses potentially dangerous advice. To call it a “detoxifying” beverage is misleading and vague at best.
    Several prominent doctors in both Western and alternative medicine urge caution if not avoidance with regards to kombucha. Dr. Andrew Weil singles out pregnant women as a group who should avoid it. Read here:
    Mayo clinic urges avoidance as well:

  9. Nocturne says

    I stopped drinking kombucha back in September when I found out I was pregnant. We home brewed and also drank GT’s, Honest Tea’s Kombucha, and High Country Kombucha. I have had a few ounces a few times since finding out I was pregnant.

    I was wondering if I would be considered someone who is continuing or a new drinker, since it has been so long since I have had large amounts (8 or more oz a day)?

    I have been having severe indigestion and my doctor has me taking Zantac…which doesn’t work much and I hate taking, but I need relieve from these digestion issues.

    I’m thinking kombucha might help.

    I’m 16 weeks pregnant now.

    • says

      Oh, wow! I’m in almost the same situation now and would love someone’s insight. I was drinking Kombucha regularly even when I first found out that I was pregnant. But then, I got sick and couldn’t stand the smell/taste. I’ve been leery of starting up again due to the ‘detox’ effects, but my digestion has gone insane and I’m missing it now.

      I was drinking it regularly for 6-8 months before now. Surely all of the detoxing would be over with by now? Or, is it an ongoing kind of deal?

      Any thoughts would be very much appreciated!

  10. says

    I love kombucha tea
    just had a baby girl : )
    As soon as I was pregnant i stopped drinking kombucha ,I paln on breastfeeding for 6-8 months so i don’t think im going to be brewing for a while .
    just to be on the safe side ,that’s OK I will stick to the yogurt for my pro biotic’s
    when im back on my feet im going to order mine from
    Kombucha Health Drink

    their the bees knees !!!

  11. says

    I was just searching for detoxifying foods and I was brought here. I didn’t know there was an issue about kombucha and pregnancy. I used to give my sister kombucha tea when she was pregnant 2 years ago and it helped her reduce muscle pains and made her bowel movement regular. Good thing nothing bad happened to her, I mean, can something bad could really happen to a pregnant? Im not a medical person though. By the way, I already tried brewed kombucha and it is really great.

  12. Anna says

    Does anyone know if pregnant and nursing women in the areas that kombucha was traditionally brewed continued to drink it during pregnancy and while nursing? Sally Fallon says that pregnant women can drink it in Nourishing Traditions and the WAPF site also recommends it. I drank a bottle here and there before pregnancy and have been drinking about 16 oz a week since part way through the 1st trimester. It seems to help me with nausea.

  13. Whitney says

    My family loves kombucha, even my one year old daughter loves it. When we are at the store she asks, “bucha mommy?” we also make our own. My five year old takes it when he gets diarrhea… and it makes him regular almost instantly.

    • says

      That’s funny, Whitney! My 2-year old loves it, too, and asks for ‘booch whenever I open the fridge. She had bad diarrhea a couple of months ago, and between the kombucha and coconut water, she was 100% better. It’s amazing stuff!

  14. Vinnie says

    You say a first time drinker can have a negative reaction, but what is the reaction? It would be good info to include in your article so the reader can weigh the potential side effects.

  15. karli says

    So I was just wondering if there is a clear answer for the question: is it OK for young children/toddlers to drink this?
    I started a home brew several months ago to help my husband with early onset oesteo arthritis (@the age of 27) :( and since then my daughter and I have started drinking it… none of us has had any negative reactions. In fact, my daughter and I were both sick recently and drank some and it really made us better. Just like a previous commenter, she is always asking for “bucha” and I do limit her consumption to about a quarter to half a cup per day. She is 3. Is there any reason why a child should not have this?

  16. Amy says

    My husband was in the hospital for 8 days / almost died from a bowel obstruction after consuming homemade kombucha. Never again.

  17. Kami says

    I started drinking kombucha for about a week to week & 1/2 because I was having digestive issues & it helped. Then found out I was pregnant! I keep hearing not to drink if you’re not used to drinking it because it may have effects I don’t want but I have yet to see an explanation of what the side effects are. It seems to be helping me be regular. Once in a while if I’ve been running errands & drink I get warm but otherwise it takes away abdominal discomfort. What bad effects am I looking for?

    • WinnieCooper says

      It seems to me that one of the side effects of drinking Kombucha is pregnancy! I’m kind of half joking, because I keep hearing people say they started drinking it, then became pregnant and didn’t know whether to continue drinking it. The same thing happened to me. I could not become pregnant until I started drinking Kombucha, then two weeks later I was pregnant! They do say that a lack of b-vitamins can hinder conception. Something to think about if you want to start a family.

  18. says

    I have been making kombucha for at least 15 years and as doctor of nutrition I find many of the concerns are unfounded and exaggerated. Drinking it in moderation during pregnancy is not a problem. Common sense should prevail. I have not been sick with so much as case of the sniffles in as many years as kombucha and a fresh organic vegetarian diet keep me fit. I also exercise regularly and get adequate sunshine. Scare stories put out by medical organizations that are killing people with drugs should give you a good indication of their motivation. Only once did my culture developer mold and it was obvious. One would have to be pretty stupid not to recognize mold when they see it. My blessings to all.

  19. Beth says

    Hi, had a question. I just found out that I am pg, just as my very first kombutcha tea is ready!!! I’ve read what you had to say about it, but I tend to be anxious about new things, and so I had a question about side effects. I read about kombutcha causing serious side effects, and I didn’t know if there were other factors these individuals may have been facing that would cause such a severe reaction. Any thoughts or advise?

  20. says

    Another thing to caution readers about before considering to include kombucha in their pregnancy and breastfeeding diet is: Do you have a family history of alcoholism?

    In general, kombucha is low in alcohol, about 0.5% for store bought and homebrew can be up to 1.5%. The 0.5% to 1.5% range is lower than anything sold as alcohol on the market. However, an unborn child experiences alcohol at around double the blood alcohol level of the mother. So, .5% is experienced at around 1% by the fetus, 1.5% is experienced at around 3%, which is the same as some beers. This is because alcohol stays in the fetus’ system for twice as long as the mother’s.

    While that may not be a big deal to some, for those of us with a genetic predisposition towards alcoholism it could be setting our children up to be even more prone to a life of addiction.

    Alcoholism is the addiction to the dopamine response in the brain when it is exposed to alcohol (in specific, it looks like a defect in the D2 dopamine receptor may be responsible). Alcohol does not create a dopamine response thoughout the brain, but rather only in the “reward pathways.”

    In other words, when exposed to alcohol (especially those of us with a genetic predisposition)the brain produces dopamine in the part of the brain that says, “Yay, that was good behavior, let’s create a chemical response to reinforce and encourage that behavior!” This happens in the developing fetus’ brain as well.

    While no one is going to have a baby with Fetal Alcohol Syndrome from drinking kombucha, those of us with a genetic predisposition towards alcoholism should think carefully about exposing our child’s developing dopamine response system to even minute amounts of alcohol on a daily basis for 9 months. Alcoholism usually develops over years, and mothers with a personal and/or family history of drug and alcohol abuse should carefully consider if they want to start conditioning their child’s dopamine reward system with alcohol this early. This could increase their chances of developing an addiction to alcohol or other substances later in life.

    For further reading on the brain and alcohol:

    There really is very little conclusive literature on the effects of minimal alcohol exposure during pregnancy. Some studies find no effects, some studies find minimal, some find negative effects on behavior and mental health later in life. The reason for this is that it is a complicated issue that depends on the mother’s life style, her specific genetics, the fetus’s specific genetics, and so many other things there is no way to control for in many studies. But what is known is that alcohol does produce a dopamine response in a fetus; the same way it does in alcoholics.

    While I love kombucha and it’s benefits, because of my family history of addiction (which I have worked my life to avoid. Woohoo! for breaking the cycle), kombucha is not a pregnancy or breastfeeding food for me. I’ll just suck it up and eat more kraut.

    And before people jump all over me, I am not saying women who drink kombucha during pregnancy are bad people or are making a bad choice; I am simply pointing out an additional consideration for people with a personal or family history of addiction.

  21. K says

    Thanks for this helpful post. I’m totally new to this (3.5 weeks pregnant, and have never had Kombucha). Last night I was looking for a healthy ginger drink at my natural foods store, to calm my tummy, and found a bottle of ginger pear Kombucha by ‘Kombucha Wonder Drink.’ I bought it because I’ve heard amazing things about kombucha, and it had good looking ingredients…and then I started to wonder if there might be any reason to avoid it, being newly pregnant; since I barely know what’s on the ‘danger list.’
    So I just wanted to ask if a store-bought, bottled kombucha drink would be any different or have the same effects, and if I ought to just give it to my husband, or maybe sip it over a few days.
    Here’s the info on the drink:
    Thanks so much for any help!

  22. Sarah says

    Not only did I drink kombucha during pregnancy and breastfeeding, but my 14 month old boy has been taking sips of my home brew since he was 9 months old. Kombucha helped with morning sickness (ginger flavored!), kept me from getting constipated while pregnant, and helped with early breastfeeding thrush. To add to my kombucha enthusiasm, I feel that it helped me to overcome infertility by alkalizing my body.

  23. Becky Shea via Facebook says

    Nursing and drink it daily! I didn’t drink it the first trimester b/c it repulsed me…my body telling me not to detoxify? Started drinking it again 2nd trimester.

  24. Kerry McRae via Facebook says

    It also tasted like beer, got it at the farmers market..hadn’t tasted one like that before.. (Didn’t taste like blueberry at all!)

  25. Jessica Valliere via Facebook says

    It is normal, the fermentation process can produce trace amounts of alcohol. In fact, some stores will card you to buy the booch

  26. Becky Iguaran via Facebook says

    So, as a breastfeeding mom of a 12 month old (who nurses 5- 7 times per day), I can safely start drinking kombucha in small amounts and gradually increase the amount I drink? How much is recommended to start drinking per day if I haven’t been drinking it? And how quickly can I start drinking more?

  27. Laura Wheeler via Facebook says

    No. Unequivocally NO. It has the same alcohol content as beer. You want to deal with FAS, or FAE, go right ahead. You want kids who can reason and function in life, avoid it!

  28. says

    Isn’t it amazing how we can get fearful of traditional and natural and real food and yet we don’t fear artificial and chemically laden food? I see more people questions whether or not it’s safe to drink komucha or tea or eat liver or sushi than I see people questioning whether or not it’s safe to chew gun, drink soda or eat microwave popcorn. #bizarroworld

  29. says

    HELP! My breastfeeding son really needs a detoxification, but I’m not sure how to go about doing it. He is 10 month old so theoretically can eat solids but doesn’t want much to do with them. I eat paleo and have GT kombuchas every now and then, but not much else. I don’t want to put even more toxins into his system by doing a detox myself but I’m not sure where to start with what to do for him :/

  30. Caylie says

    Can anyone answer this question?
    I have fibromyalgia,and a 5month old. My granoa gave me some if his home made kamboocha,1/4th a cup is about what I drank, I’ve reacted pretty negatively, throwing up shaking cold and such. I’m wondering if u have a negative reaction is it still ok to breastfeed? I’ve been doing it, because I don’t think formula is good, I just don’t know it it’s good. And I haven’t found a clear answer to this question on any websites. If anyone has an Idea please reply! Should I take him to the hospital? What should i do?
