Probiotics Side Effects Explained

Interestingly, probiotics side effects may mean that the good bacteria are working.A Here are the most common side effects:B

  • diarrhea
  • gas
  • bloating
  • cramps
  • rashes
  • acne

Assuming the adverse effect is relatively minor and does not persist for more than 14 days, then maybe we should welcome the side effects. As stated on the box of Dr. Ohhira’s Probiotics.A

Temporary reactions such as minor bloating or a mild laxative or constipating effect are signs that the beneficial bacteria are remodeling…and improving the gut environment.

The highly researched Visbiome probiotic also has a similar warning:

Possible Side Effects – You may experience bloating during the first few days after starting Visbiome as your intestinal microflora changes. If this occurs, you may need to reduce daily consumption to allow for adjustment…

Prebiotics – Another Cause of Bloating & Flatulence

There is some direct evidence that prebiotics can cause flatulence and bloating.C

So, as long as it’s not against doctor’s orders, you could try buying a probiotics that has no prebiotics in it. This can help make it more clear if it’s probiotics or prebiotics causing the side effects.

Possible Techniques for Reducing Side Effects Of Probiotics

1. Stop Taking Probiotic or Decrease Amount Taken

You have the option to stop taking the probiotic all together – this may be the fastest way to reduce side effects.

Another possible way to reduce the side effects is to reduce the dosage. If you were taking two probiotic pills daily, try taking only one probiotic pill per day. As your body becomes accustomed to the lower dosage, then you can increase the dosage to higher levels. But taking too many probiotic CFUs too quickly may result in probiotic overdose.

If probiotics were prescribed by your doctor, you need to check with your doctor if it’s okay to reduce or stop taking probiotics.

2. Change Products

Anecdotally, readers have emailed me saying that switching to another probiotic brand reduced or removed their side effects. I don’t have hard research backing this up, but this makes logical sense.

3. Support Body’s Capacity for Detoxification

According to WebMD, here’s how you can support your body’s liver detoxification systems:

  1. limit alcohol consumption
  2. mild exercise can help
  3. support enzyme production (by eating protein)
  4. eat fiberous foods like vegetables, fruit and nuts

This may work because all the probiotic side effect symptoms (diarrhea, gas, bloating, cramps, rashes, acne) can be signs of our body’s liver and detoxification systems being overloaded.

    your information was very helpful .thank you

  2. Veg mother says:

    Yes, I nothing iced that it is helping my son with his nasal drip immediately the nest morning, bit a back rash occurred causing him to itch, but I figure it was detoxification since he isn’t allergic to any of the raw vegetarian ingredients. Thank you. All other websites say to stop if rash occurs, whereas naturalist say not to…but I like the decrease amount and lots of liquid.

  3. Ashish Mishra says:

    May God Bless you, Whoever you are. You made my day! I was worrying that I could be dealing with something serious here but they’re all the sideeffects of probiotic medicines that I was prescribed.

  4. Connie Dachtler says:

    Thanks for that info, I have really bad IBS and was wondering if the pills were causing it to get worse until I read this. Thanks sooo much for putting tis info out there. It has helped me to better understand the probiotics. :)

  5. Tara says:

    After being on a round of antibiotics, I began giving my (2 yr old) daughter some probiotics – (via a mult-vitamin which includes it & a raw, organic yogurt). After a couple of days, she is experiencing a rash on the back of her neck…. I think I will scale back on her dose. I’ll also monitor the rash & hope it doesn’t get worse!
    Thank you

  6. jess says:

    Thanks so much I have been experiencing all the above.
    Have also had a really gurgly stomach and feeling quite nauseated is this normal?
    Glad I am not alone

  7. Kimberly says:

    This is comforting to know as I have just started taking Restora, which is prescription strength and have had some itching and a couple of bumps or rashes appear. very mild though. I have been diagnosed with a parasite and I am taking 3 rounds of biltricide split apart 3 weeks each round. I am also taking adrenplus, b complex, vitamin D, magnesium, and armour thyroid after testing at alternative dr.
    Thanks and a reply would be greatly appreciated.

  8. SILVANA says:

    how long does it take for the body to adjust & get over the bloating?

  9. Susie says:

    Ive been itching like crazy I thought a bunch of bugs were biting me… I hope this goes away because my stomach feels better, in finally going to the bathroom normally, so I don’t want to discontinue…

  10. sheri denato says:

    I have not been able to eat fruit for years, without getting uti. I also have been suffering from kidney problems, severe infections and stones. Have been on antibiotics for sinus infections and cipro for all the kidney infections, for so many years, I feel there is no hope.

    • evan says:

      Hi Sheri,

      I’m sorry to hear that :(

      I’d work closely with your doctors to get better.

      There is also lots of value in trying to get the basics right. Maybe working on sleep, diet and exercise could be a useful way to go as well.

      But I’d start with speaking with your doctors.

      To your health,
      Evan Jerkunica

  11. Rob says:

    I started to take some of the Dr. Wolz probiotics, one with each meal. I got congested ears and a really sore throat. I also got very tired early in the evening and I got quite achey. Is this sort of thing normal? I am drinking a lot of water. I only took one today and none of the symptoms returned as bad as they were but they are still here.

    • evan says:

      I’m glad the side effects decreased when you reduced the dosage.

      Assuming it’s okay with your doctor, it may be effective to just take the probiotic every other day.

      take care,
      Evan Jerkunica

  12. Viviana Boyer says:

    I was giving my 15 month old 1tsp bio k probiotics. The full serving is 50 billion (yogurt form) my husband accidentally gave him the whole thing while I was out. I’m worried because its definitely too much for a toddler. Should I be alarmed. What should I do??

  13. Annie says:

    I’ve been taking probiotics and a digestive enzyme for a week and just developed a rash on my neck and my stomach seems bloated. Thanks for the advice, I’m glad to hear that’s a sign that it’s working. I’ll drink lots more fluids!

  14. Peter says:

    How long do you normal experience these side effects?

    • evan says:

      It depends on the person! Could be a few days, could be whenever you take the probiotic.

      If it’s okay with your doctor, and you keep getting side effects I’d try a lower dose or different probiotic.

      Good luck!

  15. Bridgett says:

    What if I have only taken one (Garden of Life Raw Probiotics, 85 billion cultures, we were instructed to take 3 a day) & it is already causing diarrhea?

  16. evan says:

    It really depends on the person how long it will last.

    But as I mentioned above I’d consider reducing the dosage if the side effects are too intense.

  17. Nk says:

    After taking probiatic I am going through very bad time. 3 times in emergency. Went through so many tests. Dr. Couldn’t find anything. Gurgling , burping stomach,constipation, lost appetite, lost weight. What’s going on with me . Is this die off

  18. vicky says:

    Hi,my boy is currently 7months 3 weeks. He has recently lost his appetite in milk intake. Can he consume probiotic? Will it helps to gain weight? He has constipation problem since I introduced solid food during his 6 months old. Will this situation be worse if I would like to let him to consume Probiotic?

    Thank You!

  19. evan says:

    Hey Sedom,

    I think it depends. In my case probiotics worked fine for me. That being said, taking probiotics early in a leaky gut situation may not be right for all people. Slow and stead as she goes~!

  20. Peter says:

    I have an Hiatus Hernia which is causing many problems(uncontrolled gasses, burps and farts from top and bottom)I went to see Doctor who prescribed TuZen Probiotics, the pharmacy didn’t have the medicine but they had something else from Life called probiotic Acidophilus, I started taking them 4 days ago and seems that the problem is resolved already, I am tempted to stop the treatment because it has a very bad side effect, which nobody mentions it except one website of many. As soon as i take the medicine a few minutes after I get very bad shakes, I am freezing and I am out for a good ten hours, it is called flu like symptoms. Thought you should know and maybe add it so people can know what to expect.

  21. kim says:

    My 3 yr old is having issues he takes culturelle everyday and Drinks a yogurt drink. He had been sick most of the month with a cold flu whatever. He was co stipated so I have him prune juice anda small dose of miralax and had not stopped pooping he has drank some Gatorade for the electrolites but not a lot of water. Does this sound like he needs to cut back on the yogurt kefir?

    • evan says:

      If I were in your situation I would consider stopping/cutting down the probiotics for a few days and see what happens. Please work with your doctor.

  22. gurind says:

    I started taking probiotic and 3 days later I found I m feeling extra pressure for urinate evan I m a dialysis patient

  23. Ana says:

    I too have a hiatal hernia & have been really sick with shakes & then get really really sleepy. My stomach is awful too. i normally would be bloated by mid morning – didn’t matter what I ate & now its not bloated just highly irritated, me too for that matter. I have been on Floragen3 for 3 days & usually by night I feel better but I am producing a lot of gas after dinner. Cant break the capsules so I can only try every other day in hopes of this getting better as I do want this to work. Thank you for the info.

  24. teo says:

    i m using about 4 days probiotics and candida diet,but i have teribble pijn with left side of mijn rib and backache also my immune system is down,is it normal??

  25. Katie says:

    I started taking probiotics three days ago and the only ‘cleansing’ effect I’ve noticed is that I have to pee like a thousand times a day. Haha. An exaggeration, but noticeably more often anyway.

  26. Rita Bowman says:

    I’m in day four of taking keybiotics by Whole Body Research. I was feeling ok until today when I began feeling nausea, bloating, and a lot of grumbling sounds from my belly. On two occasions I went to the bathroom to throw up but the only thing that came out was a heavy secretion of saliva. I took two tablespoons of Pep-to Bismal and received minor release. I’m thinking tomorrow I will skip a day to see if I feel better and if so I will try an every other day regime. I was not expecting any side effects but this has been the only change to my diet.

  27. evan says:

    I think if you took probiotics with antibiotics, then the probiotics would mostly die.

    Other than that, I wouldn’t think it would matter. But it’s best to ask a doctor since I can’t give medical advice!

  28. Dawn says:

    I had the stomach virus 3 days ago. Not up to par but was on my way. I only took one probiotic that was specially made for women. Can one pill cause more symptoms ? Almost feeling worse since taking it. The ones I had bought have to be refrigerated and the reviews were amazing on the brand..

    • evan says:

      Hi Dawn,

      I’m sorry to hear about that stomach virus. Yes, sometimes people can have unfavorable reactions to probiotics. While it is relatively rare, I have a good friend who will get diarrhea for 3 days if he takes a low dose probiotics.

      At the same time, myself and good friends can take high does probiotics and not notice any bad reactions at all. It could be the case that you need to:
      a) try a different probiotic (we’re all different)
      b) need to lower the dosage

      Be sure to check with your doctor. They can be very helpful!

      best of luck,
      Evan Jerkunica

  29. Mickie Janney says:

    I am experiencing an outbreak of rosacea, worse case ever and wonder if taking a probiotic for the past few weeks could be the cause. I do know that injections of cortisone I receive every 2 months make my face beet red as does over heating. What do you think?

    • evan says:

      Hi Mickie,

      If it’s’ okay with your doctor, you can try stopping the probiotics for a week. If when you reintroduce the probiotics you get an outbreak of rosacea again, then the probiotics could be causing the outbreak.

      This is a question for a doctor – good luck!

      Take care,

  30. Christina Baduria says:

    Hi Evan,

    My daughter is 11 years old and she has severe eczema and very dry skin. When she was born she has eczema after several months the eczema was gone. When she turn 10 year old and she was exposed to pool and sun the eczema came back and it was severe. Can she take culturelle probiotic? Does it help to her eczema?

    She has low positive allergy with dairy and nuts. Thank you
    Hope to hear from you and thank you so much.


    • evan says:

      Hi Christina,

      There is limited evidence that Culturelle can help with eczema. Culturelle contains a probiotic strain called Lacto gg, which has been shown to decrease eczema symptoms, and
      prevent atopic eczema.

      You can read the full article here:

      You should also check with your doctor to see if this is the correct approach.

  31. Joanne Low says:

    Only my 2nd pill of Florify by Melaleuca and already my tummy has been making so much noise and pain. After 4 rounds in the toilet i felt cleansed and refreshed for my next meal. Is it a normal reaction for faeces to come out black?

    • evan says:

      I don’t think it’s too uncommon, but you should ask your doctor.

      Despite us all being human, our body can behave very differently to the same stimuli.

  32. RM says:

    Can probiotics cause nausea?

    • evan says:

      Anecdotally, I’ve heard that nausea is a potential probiotic side effect. People mention it a fair amount in emails to me and comments on

  33. vicky says:

    Hello……I started taking a product called Keybiotics 5 weeks ago for stomach inflammation and it has really helped but Four weeks in I began to develop some constipation. I usually go once a day, at least, and now I am going 4-5 times a week. Can constipation be a valid side effect until my body gets used to this supplement or should I try a diffent probiotic? thanks, Vicky

    • evan says:

      Hey Vicky,

      Anecdotally I’ve heard that constipation can happen as a side effect.

      You could ask you doctor what to do. You could also go off them for a while and see if the constipation stays if your doctor didn’t prescribe them to you.

  34. Beth W. says:

    I am on my 5th Phillips Colon health probiotic pill and I have been dealing with pretty intense nausea. Stomach grumbling, bloating and gas too. I am trying to wait it out!! :-)

  35. Paige says:

    Hi-I am new the probiotic world, and just began taking them 2 days ago. I started the Jarro-Dophilus + FOS…is this a fairly good one to start with? I am only taking 1 pill a day bc I already have a sensitive stomach. But feel like I have had some not so normal cramping and gurgling noises…is this normal? And does it tend to cause lack of appetite/sleeplessness??
    Thank you!!

    • evan says:

      Hi Paige, you are getting pretty typical probiotic side effect symptoms based on what newsletter subscribers report. The sleeplessness is uncommon, but if you have painful cramping then it’s probably hard to sleep. It seems that very few people have side effects at all, but they do happen.

      The probiotics in your body are as unique as your fingerprints, so this might just be how your body reacts to Jarro-Dophilus.

      Check with your doctor. You can also try a different brand of probiotics, you can stop the probiotics or you can see if your body will adjust in time.

      to your health!

  36. Jey says:

    I took “Probiotic caps” first two weeks I didn’t get any side effects. The third week I’m having: diarrhea- lot of gas-bloating-cramps-sleepless(I didn’t sleep 2 nights). I went to my physician and she advised to have colonoscopy test. I’m worrying a lot.
    Any suggestion?

  37. Bobbie says:

    I have been taking your probiotics for 2 weeks, the last few days my stomach has been feeling tender and gurgly. Now I’ve been very tired and feeling nauseous. Should I back off to every other day and when do I start taking it everyday?

    • evan says:

      Hey Bobbie,

      Your doctor will know best. I’d consider backing off. Maybe take a break for a few days or consider switching to a new brand of probiotics.

      Best of luck,

  38. Ky says:

    I just started using “Culturelle” capsules, 1 per day, and have noticed slight improvement in bowel movement quality.

    However, I might be off, but for reason I am receiving slight discomfort in my right thumb and a little bit in my right wrist and arm today. It’s happened 2 days in a row.

    “Slight Discomfort” referring to nothing painful, not a temperature or even really a circulation issues. Maybe best described as a slight itch or slight heavyness.

    I wish I knew how to treat this, and if in fact the Culturelle is the source. I think I take a day off and see if this symptom stops, and then I’ll know it’s likely from the Culturelle. But if so, that will make 2 treatments that cause deal-breaking side-effects for what may be a mild case of IBS. Levsin being the other I tried and it gave me clear cut case of an inflamed uvula.

    Other than a religious consumption of water and high fiber diet, or possibly a different probiotic like Allign, which my doctor suggested, I’m kind of back at square one with treating a potential case of IBS.

    Any thoughts/advice?

  39. Sharon Pinsley says:

    What about cystitis?!

  40. Robert Williams says:

    I started taking “Trubiotics” two weeks ago and I went through the gas, loose stool, bloated stage. This lasted about nine days and then it was over. I am on a diet (1200 Cal.) and my cravings for carbs has nearly been eliminated since I started taking the probiotics. I do have one question about constipation, I haven’t had a bowel movement in three days. It started just after the gas explosions quit and was wondering if this was common with taking probiotics? I don’t feel bloated and my diet is mostly protien from fish.

    • evan says:

      Hey Robert,

      Yes this type of side effect can happen for some people…though your symptoms sound on the extreme end of the spectrum.

      It may be wise to seek medical attention.

  41. Tristan says:

    I started taking Keybiotics about 5 days ago and my first few days were great but after that it has been a horrible experience, hot and cold flashes, nausea, dizzy, aches and pains, lower back soreness, sore throat, ears are stuffy, very lethargic and all that jazz. I am used to taking a 8 billion probiotic from NOW foods and the only thing I can think of is that this is much stronger and much more resiliant so i am getting a lot more active cultures in me. I have decided to drop to 1 pill every other day to help with the sysmptoms and get my system used to the CFU’s

    • evan says:

      Hey Tristan,

      If I had the same symptoms, I’d lay off it a bit. Maybe once every 3 days could be right – or maybe switch back to your old probiotic – yikes.

      Please check with your doctor on what the right course of action is.

      feel better,
      Evan Jerkunica

  42. mandy says:

    I had a colonic irrigation on Thursday and was advised to take forever active probiotic capsules, 2 capsules per day one am before or after food and one pm before I go to bed. Advised to take that dose for 5 days and then reduce to 1 day. as supply has 30 tablets, I had been bloated and belching before I took the capsules and had the colonic. Since I have been taking these capsules. I am still belching throughout the day and feel a bit sick, my skin has come up in a rash on my cheeks and chin also back.At nights I feel really hungry like I want something to eat but I am no longer bloated. Any thoughts on this please

    • evan says:

      Hi Mandy,

      I had a round of 3 colonic irrigation in 6 weeks. I had some serious detox symptoms and I felt angry all the time for about 3 weeks after the last colonic.

      I would make sure you take it really easy and relax – that’s a good way to deal with these side effects.

      Definitely stay hydrated, and also consider taking a break from the probiotics.

      You may also want to ask a doctor what to do.

      to your health,

  43. Cathie says:

    Hey, anyone else having an issue with sour saliva after taking probiotics for a couple weeks?

  44. Craig says:

    Hi Evan, just starting taking Neways Protozymes as recommended by my doc 10 days ago.
    Starting taking 2 pills per day and experienced serious bathroom sprint sessions.
    dropped to one pill per day and only showing slight improvement – no more sprinting but still VERY loose movements.
    Now have sore throat and ears – linked or coincidence?
    middle of the fence currently – persevere with the pills or pack them in.

    thoughts/ comments??

    Have taking probiotics for 3 weeks and now have terrible diarrhea and lots of bloating and gurgling in my stomach .this is not fun so I quit taking them I can’t even leave the bathroom .

  46. Mary says:

    I just took Primal Defense. My candida has gotten worse over the years and I am unable to work. I just started the diet. My question is the first day of taking Primal Defense (I took one pill), I had gurgling in my stomach. The second day, I decided to do two pills. One in the morning and another in the evening. Weird thing happened, my skin, eyes, tongue, everywhere, I was itching. Is this part of die-off? It’s a brand new bottle and expensive. Has anyone else had this problem? Thanks

  47. Kim says:

    I had my gallbladder removed in Nov and have had problems ever since. Fiber enriched foods give me gas and i have chronic constipation. I had a colonoscopy a few days ago and the results were fine. Everything i eat seems to give me gas. I know i need fiber to help with the constipation but my system is not digesting foods very well. I eat bland foods with a lot of baked fish. My GI doctor just gave me samples of Lizzness and Restora probiotic. Have you heard any good reviews in reference to Restora.

    • evan says:

      Hi Kim,

      It’s difficult to say…but it sounds like you’re accustomed to experimenting with your diet to find what works. I would do the same with probiotics. I’d be sure to ask doctors, they should have some insight.

      Best of luck,

    I’ve had my gallbladder removed 12 years ago and are experiencing acid reflux and are taking omeprazole now daily and have taken a series of antibiotics over some years, would you consider taking probiotics at this time thanks janice. Ps I can’t eat anything acidic

    • evan says:

      Hey Janice,

      I’m not a doctor, but ideally you could work with a doctor who knows about probiotics and can advise you there.

      But I I were in your situation, I’d take a low dose probiotic a work up from there. Try something like 1-10 billion or so and see how that goes.

      best of luck,

    • evan says:

      Hi Laz,

      Yes, this is a very common side effect. You can choose to push through it, or back off a bit on the probiotics. It’s up to you and your doctor.

  50. Louis says:

    I took probiotics for 1 week. Then I starred to feel very bloated and got minor diarrhea. How long should the diarrhea and gas last after I stop taking the probiotics.

    • evan says:

      Hi Louis,

      It depends. Our bodies are all very different.

      If you have already stopped taking the supplement, then you’ll probably just have to ride out the side effects.

      If the side effects are serious or persist, it may be wise to seek medical attention.

  51. Susan says:

    I have beautiful skin normally until I started Keybiotics. From the back of my neck, shoulders, my back, forearms, stomach, legs,and hands. I even saw a few spots on my butt but my hands and forearms are the worst. Is this normal? I am, however, going to the bathroom without having to take all those other pills like senna with laxative and I feel like a normal person, again. But this itching is driving me nuts. I have had oatmeal baths, white vinegar baths, baking soda baths, and I even tried apple cider vinegar because it takes the swelling down. I started on the Keybiotics March 22nd and I am 66 years old with hay fever (have had all my life). I only take one pill in the morning and cannot take dairy products, soy, gluten, or wheat. All of that resulted from stomach surgery. Is there another Probiotic that works without all this itching and my skin looking terrible? Really need some advice here. Thanks! Otherwise, I am going naturally…thank God.

  52. Brenda says:

    I have all those symptoms except acmne. Also feel VERY weak and a little dizzy. Only drinking a sm glass a day for the past week. Is this normal

  53. Winston says:

    Have a ulcer in stomach, bloated stomach, stool stick to toilet regularly and is dark. Started 50 B probiotic supplement can a change in stool color indicate probiotic working

    • evan says:

      Hi Winston,

      Yes a stool color change can indicate that the probiotics are changing your inner environment. However, a change in stool color can also come from different food or even different levels of colon hydration.

      I personally believe that a change to bowel movement regularity/firmness/quantity are stronger signs that the probiotic is working.

      I’d pay close attention and if things take a turn for the worse, seek medical attention.

      to your health,

  57. Joyce says:

    I’ve been fighting shingles now for 6 weeks and I’m still suffering from pain where the shingles blisters were located. I started 15 billion probiotics midway thru this and was feeling better. I was taking 5 billion 3 times a day. A friend coaxed me to bump it up to 20 billion. So I did this and by the 3rd day I had a rash all over my head. I’ve since stopped and the rash has gone away. I really want to go back on it, but now I’m stuck with 20 billion capsules. Any ideas on breaking these capsules in half to take half in the morning then again at night? Or should I wait til after this shingle pain goes away? I’m sure I’m in toxic overload with having fibromyalgia and type 2 diabetes. What would u suggest I do? Thank you.

  58. Lou says:

    This is what I am experiencing right now: sore throat and congested ears with heaviness of the head. Just like what Rob said he experience. I am also constipated for two days now. I found your article and now I started drinking plenty of fluid and lower the dosage of my probiotics to only one capsule a day. I hope these side effects will go away.

  59. Priscilla Pillsbury says:

    I recently came off of Align after several years,
    feeling I was posssibly becoming “immune”-
    I then tried Digestive Advantage, then Philips which made me quite ill, and now am
    on Culturelle which immediately made my stomach feel better but also seemed to constipate me. Is it harmful to switch strains of probiotics
    and do you indeed become immune after years?

    • evan says:

      Hi Priscilla,

      I don’t have scientific research to support this opinion, but I do believe our body can have “enough” of a probiotic…and that after a while it won’t do anything for us.

      I think it’s a great idea to:
      a) rotate probiotic brands
      b) rest from probiotics completely for a time (say 3 months on, 1 month off)

      Because while supplements are often a good thing, we need to let our body do it’s own thing and adjust.

      That is what works for me, so maybe it will work for you.

  60. Darleen NcCorchuk says:

    I’m 56 in great health except IBS. I can barely eat because I always feel full, bloated and uncomfortable.
    Went to a gastroneurologist and she put me on Miralax once a day and Align probiotic two times a day. The dosage on the bottle says to take once a day. Is it ok to take Align twice a day? This is my second day and I don’t feel any better. Sounds like it takes awhile.
    Any advice?

    • evan says:

      Hi Darleen,

      If you aren’t feeling anything within the first week, then I would consider:
      a) trying a different probiotic — since Align only has one strain (B. Infantis), then your body many need a different strain to “get things moving”.
      b) seeing if your doctor has any probiotics to recommend

      take care,

  61. Brent peterson says:

    Jumped from 60billion to 100billion probiotic. Within 4 days, heavy anxiety; within a week, heavy brain fog and head pain. However, anxiety and fog are ongoing symptoms (pre probiotics) for me. How to tell if it’s die off or regular symptoms? Seems more intense with probiotics.

  62. eileen says:

    I just recently took Ohhira Probiotics and developed spot rashes on my arms and upper body. I read the article that it’s the body detoxing. Should I stop or continue taking the supplements? I do have history of eczema and lactose intolerance. Many thanks!

  63. Diana Levitt says:

    When starting off what is considered a recommended low dosage?

    • evan says:

      Hi Diana,

      Personally I think under 30 Billion is a great starting dose, but it will vary per person.

    Hi U & J,

    I don’t have any experience working with people around that age. I’d ask a doctor for advise.


  65. Alison Spenst says:

    I started taking Culturelle probiotics 5 days ago, I do have a rash in and around my belly button followed by a weird smell….is that part of the detoxification?

  66. Alison Spenst says:

    Sorry forgot to ask , also I woke up this morning n my left eye is irritated n sore a bit, is this a side affect as well? AND since I am coming on day 6…should I stop taking them or ride it out. I was recently sick and all the meds the doctor had me on cleaned out all the good bacteria in me, reason why they now have me taking probiotics is to build back up the bacteria.

    • evan says:

      Hi Alison,

      That may or may not be related to probiotic side effects.

      I would check with your doctor.

  67. Alyeska says:

    Every probiotic I’ve tried has caused me bloating, gas, and cramps :( I’m very frustrated because I believe they are so good for health. I recently tried 10 billion L. plantarum and it was too much for me. Is eating fermented food/drinks a good substitute? I seem to tolerate kombucha okay.

    • evan says:

      Hi Alyeska,

      I’m sorry to hear that :(

      Have you tried a fermented drink like kombucha or water kefir? Or un-pasteurized sauerkraut? Those are generally much less concentrated than the supplements.

  68. Mindy says:

    Can probiotics make my one year olds urine smell foul? I started giving it to her about 2 weeks ago after a few rounds of antibiotics and a lot of diarrhea but now her urine is so foul smelling. No fever or anything so I don’t think its a UTI. Thanks.

    • evan says:

      Hi Mindy,

      I have heard of this happening to other people who are adults.

      I would check with your pediatrician to be sure.

      I wish your daughter well,

  69. U & J says:

    So, if one prefers not to take the supplements, what is the best natural way to go? Is there a diet to go by, like eating sauerkraut every day for a month or maybe just ingesting some fermented food or drink each day? How much? and for how long? Is there a way to get that bacteria back in balance naturally? Since you offered no advice we decided to not buy the probiotic products, due to his age. You also didn’t answer the question about sugar, coconut sugar, xylitol. Do these alternative sugars feed the parasite as well? And how about honey? Thanks

  70. Luie says:

    I just started probiotics today for the first time 1 pill after meal. I read many side effects good and bad so I will play it day by day and will post any good or bad results. great job in answering questions !

  72. Marianne says:

    Started Jarro-Dophilus only a couple days ago, and I’ve broke out in a horrible rash that just hurts. As long as I leave it alone the rash don’t itch, but it hurts. I have eczema and this seems to have made it far worse.

    • evan says:


      I am so sorry :/ Please seek medical attention if it’s severe or doesn’t go away.

      Although it’s not working for you now, there is some evidence that probiotics help with eczema.

      Once the rash calms down, you could try some non-sugary fermented food like Kimchi or sauerkraut.

  74. Brooke says:

    Hi this might be TMI but I just started taking hyperbiotics and it’s seemed to give me a yeast infection, is this a normal side effect?? Does it mean the hyperbiotics are cleaning out my system? Thanks

    • evan says:

      Hi Brooke,

      It could be. I would seek medical attention if it doesn’t go away quickly.

      Maybe stop the hyperbiotics for a week+ and see if the yeast infection goes away. I would ask your doctor what is best.

      As you can read in the comments above, there are many possible side effects for probiotics that have been reported by our readers – so it’s difficult to say for sure.

  75. Jennifer says:

    Thank you! I was concerned I may have improperly fermented my vegetables. I have always been one to jump in head first, and having dealt with Candida for many years, I was so excited to get well that I clearly over did it! I cut back and saw immediate relief.

  76. Chels says:

    Hey Evan,
    Been doing lots of research on/taking probiotics. I have been suffering from bv, yeast and uti’s since stopping birth control pills about a year ago. Now I am pregnant and wanting to try to make sure I’m as healthy as can be. A nutritionist recommended Garden of Life raw vaginal probiotics 50 billion. I took one capsule along with my prenatal vitamin before bed and woke up about 5 hours later extremely nauseas, heart racing, had loose stool and skin very hot. I know it’s a reaction to the probiotic but I don’t know if I should just stop using it or take half a pill..maybe with food in the morning?
    Any advice? Thanks!!

  77. Jayne peters says:

    Been taking probiotics for 2 days, increased dosage as suggested by retailer when purchased, to 4 a day as stomach was so painful, bloated, acid reflux. Now got diarrhoea. Hope its just getting rid of the rubbish for taking too many medications over 4 years! When should I stop if it doesn’t cease?

  78. Rachèl says:

    Hi Evan,
    very helpful thanks! i’ve been taking two capsules of 3 billion a day and willprobably cut down to one daily. i’ve beenlosing my appetite and feeling bloated also i feel very tired as well as agitated.
    this is my first round taking probiotics. as a child i used to have astma, eczema and bronchitis for which i was perscribed large doses of antibiotics. is it possible that my tiredness and agitation come from cleaning up years of bad intestine flora?

    • evan says:

      Hey Rachèl,

      If the probiotic supplement is the only thing you’ve changed, then the re-balancing of your probiotic flora could be causing the side effects. If it’s okay with your doctor, the best way to find out is to reduce the dose or stop taking the probiotics for a week or two.

      I wish you the best,
      Evan Jerkunica

  79. Heather says:

    Can taking a probiotic help with gluten sensitivity? I’ve had constant diarrhea for the past almost 4 years now. I had my gallbladder removed, and that didn’t help. I took the suggestion of a friend and eliminated gluten from my diet, and that took care of about 80% of the problem, now it’s only every couple of weeks. So I started taking a probiotic, it’s been 4 days now and I’m getting some of these symptoms, glad it’s from the detox, but I was wondering if I’ll be able to eat bread again in the future. Thank you.

  80. Kitty says:

    Thank you so much for this. I was really starting to worry something was wrong. I’ve taken probiotics before but was (unbeknownst to me) storing them incorrectly therefore consuming dad probiotics. I just started a fsh strain two days ago twice daily and a already feeling the effects. Will be reducing to ine until they subside.
    Thank you again !!!!

  81. Melissa says:

    I think this article made me feel better about what’s going on with me. I read a lot of the comments and your replies, but tell me if you think this is common. I increased my dosage from 15 billion to 30 billion (took 15 billion forever then one day began taking 30). After a few days I had diarrhea for a few days then began having normal bowel movements 1-3 times per day which is an increase from 1-2 times per week for me. I felt GREAT and was totally loving this 30 billion. Then about 6 weeks in I began having burning pain in my upper abdomen with diarrhea for about four days. All I could eat was rice. Today is the 7th day since that began and certain foods literally shut me down. I have to go take a nap and I have the terrible burning pain with a few loose bowel movements. When I wake up, I’m totally fine like nothing ever happened. I’ve lost 10 pounds in 7 weeks which is fine with me. I felt GREAT before this week long bout of weirdness! I also have had some headaches, skin itchiness, and I’m so tired. Could this all be detox symptoms in your non medical opinion (which I prefer by the way – don’t get me started on why)?

    • evan says:

      Hi Melissa,

      I’m glad you had some good results, but these recent side effects sound terrible!! Rapid weight loss can be a sign of trouble.

      I would really encourage you to check with your doctor on what to do.

  82. G Shanti says:

    I have a couple of questions regarding probiotics.
    1) Since the are reports of special strains of bacteria in people who eat special foods (seaweed for example), I would imagine that the ideal gut bacterial colony for your gut depends on your diet. If yes, are there studies that have attempted to look at what is the right colony for which diet?
    2) One would imagine that if you take a probiotic for a certain number of days you would be able to establish a stable colony of the bacteria in your gut and that overpopulating the gut with that bacteria could potentially be problematic. What then is the rationale for manufacturers recommending lifelong supplementation? Are there issues with the strains marketed? or is this just business trumping science?


    PS: I would prefer honest answers to the above, or none :-)

    • evan says:

      Hey G Shanti,

      We only have honest answers here!

      1) The food you eat will feed some probiotics, and starve others. Therefore your probiotic colonies will adjust their population to match your diet.

      2) The rationale is that manufactures want a lifelong customer. You are 100% correct that it is possible to over-supplement one type of probiotic…and that will give you wrong mix of probiotics!

      I personally don’t take a product no more than 3 months at a time. After 3 months I then switch to a different one for at least a month, or take nothing for a month.

      very insightful questions,

  83. Mera says:

    I had a pretty violent reaction to my first 5 days of “extra strength” probiotics. It triggered the worse IBS episode I ever had, complete with chills and a fever that clocked in at 101.3 and lasted about 18 hours. I couldn’t sleep b/c I was awakened every hour to relieve myself. When the fever went away, I was left with passing mucus alone, and mucus with stool. I stopped taking it. LESSON: I probably began with too high a concentration and should have begun on the bottom rung. Will try again with a lower “dosage” when this bout of IBS goes away because I won’t tolerate these side effects.

    • evan says:

      Hey Mera,

      Wow – that sounds beyond terrible. Please seek medical attention if the symptoms persists wow. Many people want to jump right in with the best/strongest, but some people can experience side effects. Unfortunately science can’t yet predict who is likely to have side effects and who won’t.

      best of luck,

  89. Aaina says:

    I took a 50 billion dose of probiotic 2 days ago. For two days, I have been constipated, very bloated and nausious. Today I ate prunes, and I have been experiencing intense diarhea for half a day now and grumbling noises in my stomach. My nutritionist said to decrease the dose but still continue- but should I be? It’s a pretty uncomfortable experience so far.

    • evan says:

      Hi Aaina,

      If I were personally in that situation I would consider stopping the probiotics for a while…or just taking them only every few days.

      Once your body has gotten used to the dosage, then you can start increasing the dosage or start taking the probiotics evey day.

      Obviously seek medical attention if the side effects don’t go away, or becomes severe.

  90. Deborah Johnson says:

    I just started taking Restora, given to me by my doctor. So far, so good, except, about 30 minutes after taking it I am getting a headache and some nausea. Is this normal. I am really not a headache person so this is a little troubling. Other than that, I am very pleased and intend to continue. My other symptoms have really normalized. I am a happy camper.

    • evan says:

      Hi Deborah,

      Typically probiotics aren’t going to cause that sort of side effect that quickly. Did it possibly get stuck on the way down as you were swallowing?

  91. Judy says:

    Have been taking probiotics for a few days and the directions said take (2) if you are having stomach upset and diarrhea so I did. Bad case of diarrhea today, not sure if I should quit already of just cut back to one.

    • evan says:

      Hey Judy,

      You can quit the supplement to give your body a break. Once your body goes back to normal, you can start taking the probiotics at as low a dose as possible..say every other day or as few pills as possible.

      Please go see your doctor if this doesn’t fix itself, or if it gets worse.

    Started taken them last week on the 13th by the 15th the bloating the gas the pain still going on and it’s the 22nd you can see the bloating all day long I go to sleep fine then in the morning take 2 then it begins take 2 more not to realize that this may be the probiotic till i started doing research,to fine out this can happen. Well I’m going to stop taking them to see if the bloating goes away and the pain and gas.
    even went to my dr she thinks I need to see a GI dr they don’t talk about the problems that can occur but i will see if this is the reason.
    Does anyone kn ow once you stop taking the probiotic how soon you feel better I want to be able to eat Christmas dinner and feel fine and not want to go to the hospital my last does was 3pm today took 2 and earlier in the morning took 2

    • evan says:

      Hi Chris,

      If the side effects are too intense your options are:
      a) go see a doctor
      b) decrease the probiotic dosage
      c) stop taking the supplement all together

      Especially if it gets severe or doesn’t go away after you stop taking it, I’d go see a doctor.

  93. Manda says:

    For the author of this article,

    Now I have a complete understanding on my Probiotics Eleven I’m taking daily. I’ve been trying to figure out which of my natural suppliments have been causing me to be constipated for a long time, and of the three natural suppliments, it’s my Probiotics Eleven. I think its also because I’m also taking 3 different types of anti depressants and birth control is why I’ve been very constipated. I wasn’t having bm issues this bad until I added my natural suppliments to my prescribed medications. I was recommended Probiotics Eleven by a naturalist that owns his own herbal store for my sinus and ear infection, as well as Olive Leaf Extract and Magnesium. I’ve only been taking them for 3 weeks now as recommended, but being constipated and bloated is not fun for me. Will I continue with constipation and bloating after my first bottle usage is gone? Or will I go back to “normal” when I buy a second bottle?

    • evan says:

      Hi Manda,

      That is a pretty complicated mix of supplements. Can you work with your doctor to maybe swap out some supplements that aren’t as necessary? Then you can see what will make the constipation go away.

    Can very strong probiotics be given to children? Is 50 billion or 100 billion too much for a child if they are experiencing severe issues like eczema and gut problems?

    • evan says:

      Hi Tia,

      I would consult a pediatrician. But if they were my child, I would start very slowly.

      I would maybe try something like 1/2 a pill, mixed into something, every other day and see how that worked.

    • evan says:

      Hi Chris,

      If it’s been too long, then it’s wise to see a doctor to prevent really serious problems.

      If it hasn’t been too long, then there are a number of ways that might help get things moving, depending on your situation. Here’s what I would consider doing if I were you:

      • Have you tried drinking more water?
      • Have you tried going on regular walks?
      • Have you tried doing breating squats?
      • Have you tried gently massaging your intestines?
      • Have you tried a squatty potty?
      • Magnesium citrate can be useful, but you need to work with a doctor.

        You have to consider if any of these are appropriate for your situation…I’d strongly consider seeing a doctor.

  96. Lulu says:

    I always have had good bowel movement until I took antibiotics for my ear infection. It sort of has upset my stomach so I ended up with heart burn, gas and acid reflux. I started on a 20 billion probiotics and it was great. The heartburn disappeared, and I was barely gasing. But I realiZed I haven’t been to the toilet for 3 days now. I do have a little bowel movement but it is very little. Should I worry? How long do I have to wait for the side effects to kick off?

    • evan says:

      Hi Lulu,

      The side effects really depend on the person. I would start by cutting down the dosage. Could you take them every other day? Take fewer each day?

      And if constipation persists or is painful, get to a doctor.

    Ive been plagued with thrush for years now including scalp an hairloss problems ive also had very loose bowels in the morning so i thought id try taking probiotics.Been taking them for two weeks now scalp feels alot better an believe it or now hairloss has decreased tremendously!been taking 2×3 billion however been very bloated an bowels have really slowed down!i will cut it down to one capsule a day then go back up to two daily!probiotics are amazing an i wished i started taking them years ago might have kept my beautiful curls!!!

    • evan says:

      Hey Kez,

      Yes I miss my hair too! Well hopefully your sharing your information can be useful for someone else.

      I’m glad some of your symptoms are improving, but I’m not happy about the side effects your experiencing. You can try different products can potentially increase or decrease the side effects.

      I like that you’re cutting down the dosage, that should help reduce the side effects.

      Please be sure to pay close attention to the side effects and seek medical attention if they get bad.

  99. John says:

    Starting taking probiotics, and noticed after day 3, after I eat I have a feeling of dizziness which then causing some anxiety because this isnt normal for me to happen. I see a previous comment about it not being a normal side effect. Has anyone else been experiencing this sort of a thing?

    Been taking – 1 Pill a day of a 1B culture pack,

    • evan says:

      Hi John,

      Personally, if I were in your situation, I would not continue taking that probiotic.

      If the dizziness didn’t go away, or if it were severe, I would seek medical attention. This is not something to mess around with.

      Evan Jerkunica

  100. Lilly says:

    I took a probiotic as the recommended doseage stated. At first I felt good, day 3 I got so sick! I had awful gas, bloating, belching, pain in my ribs, stomach, and center of my back and right side. constipated, I was miserable. I missed 2 days of work, laid up in bed for a week. I could not eat, so nauseated. After 14 days, I stopped taking the Probiotic. The symptoms stopped in 24 hours. Thank God. I have Permicious Anemia PA. I will never take Probiotics ever again. If you have Anemia, seek your Physicians approval before taking Probiotics. Its not safe if you have a pre-existing condition.

  101. Jourdan says:

    Hi! I’m new to probiotics. Can they cause anxiety? I tried coconut oil and it gave me severe panic attacks because of the “die off” and I don’t want the same thing to happen with this. I’ve heard that once you get use to probiotics they can take anxiety away but I don’t want to suffer from panic attacks again.

    • evan says:

      Hi Jourdan,

      Anecdotally, some people have mentioned having more anxiety when taking probiotics. But, there is also limited evidence that probiotics “improve mood and health outlook”.

      Now obviously antidepressant type drugs are way more proven for this effect than probiotics are, but there is some early promising evidence that probiotics can help to a degress.

      If you’re afraid of the die-off, then make sure to take a low dose of probiotics. Start with a brand that has 1 billion CFU, and take just 1 pill and wait 3 days to make sure everything is fine.

      Then if everything is fine, work up the frequency to 1 pill every day. Then if that’s fine, take 2 pills a day, etc. Good luck!

      But starting slow and ramping up seems to be a good way to limit/prevent side effects.

      And as always, please actually check with your doctor. Supplements could interfere with a drug you’re taking, or a health condition.

      to your health,
      Evan Jerkunica

  102. Steph says:

    Hi, I have recently followed a candida diet and protocol to treat candida-the latter part or the regime required probiotics which I’ve been taking 50 billion per day for 3 months now. During the last few weeks I have increased to 350 per day and felt really good. I showed signs of clearing such as nasal mucus. I continued to increase as I am trying to regulate my bowels. For my 42 year life I have generally only had bm every 4-9 days. During last year they are 2x daily – alternate days. I accidentally increased from 350 to 550 per day too quickly and had a fever, headache, glands ached, discharge, sore mouth. These have cleared over last week and I stopped all probiotics. My Q is how quickly can I safely increase probiotics again. Should I start right back from 50 billion or would I be safe to move fairly quickly to about 250 billion then slowly from there. Also I was diagnosed with rhuematoid arthritus 1 yr ago -which started my journey to health and candida recovery. I noted whilst on the probiotics and at the end of my candida plan that my RA had finally gone into remission. Then when I overdosed on probiotics some swelling of joints returned. I believe this to be because of toxin build up or is it something else? I read that although probiotics don’t colonise if you take them for 6-12 months you should then be able to lower the dose back down is this true? Lastly, I did have some constipation with the probiotics and so took pysillium husks at bedtime to help. Will this sweep the probiotics out if my gut though?

  103. Melanie says:

    Hi. I took 250mls of a kefir drink 2 weeks ago and have had diarrhoea ever since. Like every time I wee I poo loads!!!!!
    It seem to be slowing down in the last 2/3 days. Thank god, but I bought some probiotic capsules called Optibac, amazing reviews. Took my first dose yesterday morning with my porridge. This morning I was on the toilet for ages and I know I will be going again!!!!!
    Honestly, until reading your article I was more scared, thinking I had something seriously wrong. Still a bit worried, but I want to take them as I know they have so many health benefits. Will all this go away??!!!! Do you know of anyone that just can’t take them?! Thank you so much for listening to me witter on about myself.

    • evan says:

      Hi Melanie,

      I have a good friend who if he takes about 3 Billion CFU, he will have diarrhea for 3 days straight.

      Personally, I can take about 10x the heaviest dose (which works out to 10×100 Bilion CFU) and I won’t get any side effects.

      It really depend on the person. If I were you I’d make sure that I am getting enough water, rest and trying eating different foods (maybe more meat/less meat).

    Fascinating page, thank you to all who posted here and especially Evan who puts in so much time to this.
    Something nobody else seems to have mentioned… I get terrible side effects from most medicines, including natural ones. Hving taken a lot of antibiotics etc I got sick of the doctor as well of being ill and decided to go on probiotics.
    You need to eat the right foods for them to feed off of.
    Garlic, onion etc. I ate some garlic and was very ill for a long time, so instead have onions to help it. Foods are prebiotics. YOu can google listst of them.
    I tried Dr Ohirras and found it quite good.
    But somehow I hvae a cough and sometimes get heady.
    Assumed this is acid reflux though do not get the other symptoms of it. It comes and goes.
    Switched to bacillus coagulan and found it helped.
    Then wanted a higher dose one so switched to a different make which contains 600,000,000 ! wow. Sounds like a lot, so much more than the first ones. But in real terms it is not much.
    Have had sore throat, rash, nausea, palpitations, diarrhea, brain fog, congested ears etc. Some of which has gone.
    The doctor is monitoring me for underactive thyroid.
    Most of these symptoms are the same as underactive thyroid and the blood tests will prove it.
    Am not totally well but am a lot better than I was a few years ago when I just took antiboitics and steroids and was often feeling so awful I cried and cried.
    Would you please respond if you can tell me of any other side effects you have had from taking biotics and if any of you have taken them to help with a cough or got a cough through them. Thank you and hvae a nice day.

    I am experiencing mild diarrhea after beginning to take 90 billion strain probiotic. It’s not uncontrollable, just slightly loose stools and regularity. I want my body to get used to this strain, since I do believe my stomach needs the good flora and extra assistance. Should I wait it out and see how long the diarrhea lasts? It has only been 3 days that I have began this probiotic. (Ultimate Flora)

    • evan says:

      Hi Mary,

      It really depends on your level of comfort. Personally, if I had side effects for longer than 5 days, I would cut the dosage in half or take a break for a few days.

      If the side effects didn’t stop or became severe, I’d go ask a doctor what to do.

      to your health,

    Could itchy spots that look like bites be part of the detox? I stopped taking mine for a couple of days but only because i forgot an realised when i started them again the spots that looked like bites started to itch again! Strange there isnt many of them however they are very itchy indeed…but i will continue because the benefits are outwaying the side effects! I still think probiotics are brilliant!

  107. kez says:

    Oh an Evan my bloating an constipation has stopped now….took a while tho dig enzymes really really a senna at some nights also!

  108. Red says:

    Hello, I started off taking probiotics 10 billion for a month things seem to be going great i even noticed less cellulite on my inner thighs and felt lighter and i moved quicker had a little pep in my I had nice bowel movements too. I then decided togo higher since things was going great then i decided to try Renew 90 billion probiotics and after couple weeks of taking this one i seem to have lost m guess appetite could taste my foods. Is this normal? Well i stopped for a couple of weeks now and my appetite is back.

    • evan says:

      Hi Red,

      I think you did the right thing…if you experience too intense of side effects it’s best to just stop the probiotics :) And as you saw, everything went back to normal after a bit.

      Your side effects aren’t typical, but they do sometimes happen…though losing your sense of taste is very atypical. I would consider asking a doctor what happened.

      to your health,

  109. Joan says:

    Hey evan. Thank you for taking the time to answer the many comments. Much appreciated. I took my first probiotic last evening with a light meal. This morning after breakfast, I had a normal bowel movement, but that was followed by three quick bouts of diarrhea. I drank a glass of h20 in between each trip to the bathroom. Seems like it’s stopped for now, but I feel a little nauseous. Is it typical for the probiotic to work that quickly? Just took me off guard. No doubt I have unhealthy bacteria that needs to be cleansed.

    • evan says:

      Hi Joan,

      Thanks for your question!

      Yes – probiotics can work very quickly (and violently). Typically people see changes within a week – though many people see no changes for 3-4 weeks.

      take care,
      Evan Jerkunica

  110. Chris says:

    I was in a really bad car accident and the doc had me on a lot of pain meds. About a week ago I quit the meds and started taking probiotics. I’ve had a lot of the systems listed including diarrhea, nausea, and abdominal pain. How exactly do the meds affect the stomach and what are the probiotics doing?

    • evan says:

      Hi Chris,

      I don’t know exactly how pain medications and your digestive system interact. I’d chat with your doctor about the specifics of how that works.

      The good news is that there’s TONS of research showing that probiotics help with diarrhea…that is probably the single most proven condition to be helped by probiotics.

      I’d ask your doctor if probiotics are the correct course following taking pain meds.

      I wish you a speedy recovery,
      Evan Jerkunica

  112. Mallory says:

    Good Morning,

    My daughter is 2.5 and has suffered from eczema since 3 months of age. It was recommended to try a probiotic to help improve her gut health because along with eczema she has bowel issues. She recently has had quite a few horrible flare ups from weather change and a gave exhausted All topicals so
    I am not trying to repair from the inside. She is also allergic to egg, tree nuts, and peanuts. We started giving her 1/8 tsp of Maxi Baby Powder Probiotic and she had a horrible outbreak about 15 minutes after! Is this normal? I am nervous to continue the use because of the immediate affect! Please help I just want to find a solution to this horrible skin issue!!

    • evan says:

      Hi Mallory,

      I would talk with your doctor about this issue with the probiotic side effects…I don’t think a bad breakout after 15 mins is okay.

      to your daughter’s health,
      Evan Jerkunica

  113. Joan says:

    i have been taking a number of supplements and a multivitamin each day for years. Recently, I have started taking Mega Flora Probiotics, but wanted to ask if it’s alright to continue to take vitamins/supplements. Do they interfere with the absorption of the Probiotics or work against it?
    Thank you.

    • evan says:

      Hi Joan,

      I believe if you were taking an antibacterial supplement, it could hurt the probiotics. Something like HCL supplements could also hurt the probiotics before they can operate in your intestines. Otherwise, I think the probiotics should be able function correctly.

      To your health,
      Evan Jerkunica

  114. Robin says:

    My daughter (25) has terrible acne. Literally we have tried everything. Our newest approach was to treat this from the inside. She is eating more vegetables, no processed foods, lots of water and is now taking pro biotic and turmeric. We are about 2 weeks into this and she has started to get more acne. I noticed you mentioned that that acne could be part of the detox process-can you respond to this? I think it must be a good thing that more garbage is coming to the surface and leaving her body. Thoughts?

    • evan says:

      Hi Robin,

      I would speak with a doctor about that. Sometimes things look worse, in the process of getting better. It is difficult to say.

      to your (daughter’s) health,
      Evan Jerkunica

  115. Robin says:

    Thank you Evan for your response.
    I will keep you posted on our progress! I am hopeful that we will win this battle!


  116. Arianna says:

    I started taking probiotics 3weeks ago and didn’t have any side effects. However,3rd week in and I am starting to have gas and some diarrhoea. Is this delayed effect normal? Thanks!

    • evan says:

      Hi Arianna,

      Yes, it’s not uncommon for probiotics to have no side effects at first, and then start having some later. If I were in your situation, I would consider stopping the probiotics for a while, and see if the diarrhea goes away.

      I would see a doctor if the side effects get severe, or don’t go away.

      To your health,
      Evan Jerkunica

  117. David says:

    Hi, I had an intestinal candida infection confirmed by stool test. I’ve managed to cure it with diflucan and strict diet. After that I started taking some extra high potency probiotics of 500 billion cfus per dose + I am taking once daily saccharomyces boulardii 5 billion cfu, the first week was okay but today I’m entering my second week and I have some extreme stomach pain almost like heavy burning sensation. is this some cleansing side effect?

    • evan says:

      Hi David,

      That is not a typical side effect…did a doctor recommend you start at 500 Billion CFU? In my personal experience it’s wise to start under a 100 Billion for sure, and many start under 10 Billion…do your own research and ask your doctor, but that sounds like a very large dose to me.

      To your health,
      Evan Jerkunica

  118. Victoria Hochman says:

    I starting taking 5 billion Natures Way and I completely exploded with bowel issues. It took me 3 days to realize it was the probiotic. I stopped taking it. I actually felt energized and in a great mood when taking it, besides that debilitating side effect. After one week off them, I went back on breaking open the capsule and pouring a small amount in water. Ive been having bad gas now. Please let me know how I should proceed? Im obviously have some difficulty but want to continue as my joint pain is all but gone and my mood is much better. Thanks for anything you can offer.

    • evan says:

      Hi Victoria,

      If the the benefits outweight the gas, then maybe consider riding out the gas for a few days?

      Or maybe take the probiotic once every few days? Or try taking every less of the probiotic? Or take the probiotic with food…or take it on an empty stomach first thing in the morning.

      Those are the things I would try if I were you.

      I’d check with your doctor because I’m not a medical doctor!

      to your health,
      Evan Jerkunica

  119. Victoria Hochman says:

    I forgot to ask something quite important…. Do these side effects go away after you have detoxed or does it continue forever if you’re on probiotics?. I don’t eat sugar or carbs and eat a pretty clean diet. Im going to drink more water to flush my system out, now that Im taking probiotics. I need to know, is there light at the end of the tunnel?, (no pun intended). Thank you so much for taking the time to answer and guide me through this journey.

  120. Victoria Hochman says:

    FYI I have been in the best mood. Is mood change a side effect? If so, Im going to be an addict.

  121. Evelyn says:

    I just started taking probio due to i am diabetic, and the next day I have rashes and itchiness on both arms…after reading this now I understand I will just take one a day to see if it will decrease my itchiness. …I am also taking tegreen, Cholestin and marine omega, also my hydrochloride for my BP and atorvastatin for my cholesterol. …thank you

  122. Kelly says:

    Do you know if oil of oregano can be taken with probiotics?

    • evan says:

      Hi Kelly,

      Oil of oregano is antimicrobial, so I assume you should take it an hour or 2 apart from the probiotics. But a doctor would know better – so ask them please.

      to your health,
      Evan Jerkunica

  123. Arthur says:

    I took a 500 billion count 34 strains probiotic and then increased it to 700 billion a day. This cause me sever problems. Pain and bloating in my gut along with sinus blurred vision and other problems. I stopped taking the probiotic about 3 day ago but the bloating and other problems have continued and seam to be worse. What if anything can i do about this


  124. Tamica says:

    I just started a 30 billion CFUs probiotic and immediately after taking it I began to feel jittery, stomach started to hurt. It sent me to the bathroom and my heart is starting to race
    It didny say anything about these side effects is this bad

    • evan says:

      Hi Tamica,

      I’d check with your doctor. And if you chose to take probiotics yourself, I’d consider stopping to take them. Otherwise listen to your medical professional on what to do.

      take care,
      Evan Jerkunica

  125. FS says:

    After taking antibiotics I started taking probiotics, both for my mouth and my gut. However, I did notice one perculiar side effect: huge bowel movements…I mean much larger than what my food consumption justifies. I’m like OMG huge: could this be all the bad bacteria being passed thru?

    • evan says:

      Hi FS,

      I recently took antibiotics and it screwed me up for about 6 months…so I empathize!

      It’s hard to say specifically if the probiotics or antibiotics caused the issue.

      I would keep an eye on it – but probably not anything serious. Consult your doctor if it gets worse.

      take care,
      Evan Jerkunica

  126. Cheryl says:

    Would it be normal to have bleeding with the diaherra caused by taking probiotics? I do have an ulcer and am scheduled to see a GI doctor soon. Think I will stop the probiotics until then. Your thoughts?

    • evan says:

      Hi Cheryl,

      No, bleeding + diarrhea is not normal with probiotics.

      I think it’s good that you stopped taking them.

      Please work with your GI doc and see what he/she recommends.

      take care,
      Evan Jerkunica

  127. Farrah says:

    After being on Antibiotics for a sinus infection I took Garden of Life for women (85 billion). I took 3 per day as directed on the bottle. I had the worst bloating and gas and heartburn and it got much worst as I continued. I could hardly eat. I took it for 2 weeks and thank god I found this site. I had never suspected the probiotics were the cause. I have discontinued the probiotics for 4 days and my symptoms are slowly going away. I still am somewhat bloated but I can see the rapid progress. I am very active and have a very healthy diet. I had never experienced these symptoms before. Although each person is different, I am listing what is working for me in getting over probiotics side affects, in case it will benefit someone else:
    1- I follow an alkaline diet ( no tomatoe, onions, garlic,etc.) during this transition period even raw fruits and veggies bother me. I basically use Dr Judith Kauffman reflux book as a guideline.
    2- I have alkaline water
    3- I am a vegeterian, I don’t eat meat ( I am sure there are lowfat meats that will work for meat eaters), during this transition period, for the first time in my life beans give me horrible bloating, gas. So I eat eggs, egg whites, brown rice, boild spinach, avacados, brown rice, toast,nonfat plain greek yogurt ( I like wallaby organic). small amounts of farmhouse sauerkraut ( caraway seed), some boiled vegatables. bananas, No alcohol. no milk, or cheese or greasy or fatty food. I prepare veggie stews with cuman and fresh grated ginger. During this transition period my stomach has a hard time digesting nuts ( never had problems before).
    4- Manuka honey, fresh ginger and chamomile tea have helped a lot with gas and heartburn.
    5- I have very small meals several times through the day and don’t eat out.
    6- I have found walking really helps me.
    7- For bad heartburns ( I never got heartburns before) zantac has really helped me. Though I go easy on them and have them when I need them.
    8- I don’t eat anything 3 hours before bed
    It is quite disturbing that probiotics do not list the side affects. I had no idea they could mess up my system so badly. I had never had any problems with my gut before this experience.

    Thank you so much for this site and comments.

    • evan says:

      Hi Farrah,

      You’re very welcome. I’m glad you found the problem.

      Thanks for sharing your health tips.

      I personally need lots of meat! But ya, walking and more intense exercise are key for me too.

  128. DSDM says:

    Not sure this is an active thread but I thought I would give it a shot. I am a 50 year old male. I have been on antibiotics for 35 years due to acne and then chronic sinus issues. Not surprisingly I also developed GERD. For 16 straight years, I took some form of a PPI. Also, I had a diet fairly heavy in added sugars. No one ever told me about probiotics.

    In September of 15, my stomach completely gave out. I became extremely ill and could not keep anything in. I went to a gastro. After doing all the normal testing, she indicted that I suffered from SIBO. Yet, more antibiotics. However, she did recommend probiotics and a massive change in my diet AND to discontinue all PPI’s.

    The next several months were brutal. In April of 16, I stopped taking PPI’s and took Pepcid as needed. I experimented with store bought probiotics for a while. Finally, in Sept of 16, I ordered perfect probioitcs (30B CFU’s, 15 strains) and changed my diet which included a drastic reduction in sugars. I figure my diet previous to the change consumed about 50 to 60 grams of added sugar. Now it is probably 6 to 8 grams daily, sometimes even lower.

    The good news 3 months later is that the GERD is gone. I have taken 2 Pepcids in 3.5 months. I suffered from Adult Acne. That has greatly receeded as well. I had a cold last month that, for the first time in 25 years, did not turn into a sinus infection.

    The bad news is that I still have gas/bloating, loose stools that don’t evacuate properly and have to go several times a day. Again, it has been a few days more than 3 months. I don’t want to stop. How long should I give the probiotics? Is this normal for someone who spent decades destroying his stomach? I did have a CAT Scan and nothing structurally wrong was found. I want to stick with this. I have definitely seen some benefits.

    • evan says:

      Hi DSDM,

      I’m glad you are seeing some improvements between the diet change + probiotics. I personally am not a fan of PPI’s so I’m glad when people get off them.

      When someone has been on antibiotics for 35 years, it would not surprise me if it took a while to see full improvement any faster than a year or 2.

      It’s also possible that you have other issues going on – there are many causes of loose stools. I’ll list some common ones below that you can check out:

          get tested for parasite and candida infections
          check for food allergies – gluten, soy, dairy, etc.
          i never stay on the same probiotics for 3 months – spend at least 1 month on another brand
          are you still on antibiotics for SIBO? antibiotics can cause loose stools as well
          have you tried swedish bitters before a meal? or some diluted lemon juice before a meal?

      Please consider checking those out and see if you can get improvements from those avenues.

      Obviously check all of the above with your doctor to see if there are good reasons not to do them – good luck!

      to your health,
      Evan Jerkunica

  129. DSDM says:

    Thank you so much. I have been tested for parasites and Candida and came up negative. I do avoid dairy at all cost! I would say my diet is low in gluten. My gastro didn’t seem to think it was an issue.

    I am not on the antibiotics for SIBO. Actually, my last round was a year ago. That was my 3rd round. I would see an extremely minor improvement that would go away as all as I stopped taking the drugs. My theory was that I literally had no good bacteria left so the bad bacteria would just repopulate after the drugs. In 16, I was only on antibiotics (knock on wood) for 5 days (levaquin) for a minor sinus infection.

    I will look into food allergies. I am so limited with what I eat now that I am concerned about loosing too much weight.

    I definitely want to stick with this and appreciate your feedback that it could take a while. If someone told me that I would feel this level of discomfort for the next year but would feel much better afterwards, I would take that deal. After I am through with my course of probiotics, I will switch brands. Is there a link anyone can provide that has brands of high quality and reputation?

    Thanks again for the reply. I really appreciate it.

  130. DSDM says:

    Sorry! “Provide a link that has brands of high quality and reputation?

  131. Amber says:

    I’ve somewhat been taking this for a week or so but not really remembering it everyday. When I did take it I was taking it after dinner, three pills as the bottle said. No problems. But I took it about 3 days in a row like that and now… I am miserable every time I eat. It’s now noon Saturday but Thursday night was the last I took it, I was up the majority of the night sick. But I was better in the morning but every time I ate I started feeling bad again. I ate a bit earlier and now I’m back to being miserable :( My stomach is “rolling”, oddly my upper back is hurting rather than my lower back, and of course every so often I have to run to the restroom. Would you suguest just cutting the dose or maybe just not take it everyday? I just want to feel better

    • evan says:

      Personally, I would stop taking it. But of course listen to your doctor if case he/she instructed you to take it a certain way.

    44 year old taking probiotics once a day (for the first time) and fish oil 1400 mg twice a day. Broke out with significant acne worse than even as a teen going through puberty.

  133. Renee says:

    I have developed itchy red bumps on the back of my neck and they itch to high heaven ! I took me a bit to figure out this maybe from the probiotics it was the only new thing introduced within the last 2 weeks. I will be stopping them for now.

  134. Elena says:

    I just started taking probiotics 1 week ago to help clear up my acne. I take one in a powder form, mixed in water in the morning and 2 capsules in the evening, along with zinc and a woman’s supplement. The last couple of days my acne has started to clear up but I’ve been bloated, constipated and have put on 5 pounds. What would you suggest I do?

    • evan says:

      Hi Elena,

      Personally, I would introduce 1 new supplement at a time. That way you can have a useful idea of which supplement is causing side effects.

      Next, you could consider taking a lower dosage of the probiotic to see if you get the acne benefits, but not the bloating/constipation.

      I would speak with a dermatologist or doctor and see how to best proceed.

    Can probiotics cause nausea, stomach pain, and the need to use the bathroom more often? I just started taking some yesterday (started out with 2 capsules, as was the recommended dosage) and later that day those issues started popping up…. could it be the probiotics?

    • evan says:

      Hi Crissy,

      They can – as well as other things. If it’s a very serious case, consider seeking medical attention. If it isn’t that bad, you could consider just not taking the supplement any more. It’s up to you.

    Started taking Silverfern probiotics….took for about a week and a half and have developed severe itchy rash over most of my body except my face. Stopped taking a week ago, but the rash has not gotten any better and is driving me crazy. Is this an allergic reaction or should I keep taking the probiotic? I know there is a herkheimer reaction that can happen before you actually get better. I am just not sure, but I need this to get better. Thank you!

  143. Lee says:

    As I wrote previously, I was having problems with taking the VSL3 recommended by my GI for IBS. Terrible gas in my abdomen and chest. I cut back from one per day to one every other day which he said was OK. Still having the same issues after taking it for two weeks. Talked to a pharmacist at The company that makes and distributes VSL3. She said those side effects should only last 7-10 days. My doctor isn’t providing much information about options or safety factors in continuing or stopping the medication—just that if I have symptoms that bother me to stop taking it and see if they go away. What a revelation! If taking the medication has caused the symptoms, I would sure hope that not taking it would make them go away. Any experience like this with VSL3? Quit after two weeks or keep going?

  144. Em says:

    Been feeling rather ill lately. Body aches, headaches, nausea, etc… I started taking double my usual dose of probiotics. A couple days later, although I was mostly feeling better, I got a persistent bout of diarrhea. It’s helpful to read this article and understand how that maybe have happened. I will go back to my usual dose and see how things go. Thank you.

    Hi there, maybe I will get a response.
    I started on 20 Billion Probiotics from Nature’s Way, it contains Soy, which I eat because I’m mostly Vegan, it has no dairy,fish,gluten,etc.
    After a few days of taking it,my stomach became so sore, cramping,bloating & pain,bowel movement 1-2 times a day,it also increased my anxiety,,& gave me more rapid heart movement, I’ve been off of it for 3 days,and I’m feeling better,hoping I’m doing the right thing as I’ve been to the doctor twice. They ran blood tests,and everything checked out fine, so any advice besides drinking fluids? Thank you

    • evan says:

      Hi Paulina,

    After having a bowel movement I become a little nauseous, feel bloated and slot of gurgling in my gut like I feel things moving quickly. I started taking a probiotic and now my stools look close to black in color. Is this normal?

    I started taking a new probiotic in February. This one had prebiotocs too. About 3 weeks later I developed explosive diarrhea (10-12x pee day and at night) for 4 weeks. Went to UC, doctor and gastroenterologist. Every test said I was perfect so they suggested stopping probiotic and scheduled colonoscopy. Two weeks after stopping my low dosage probiotic, I no longer have diarrhea and am now constipated and dehydrated. I don’t do well with being put under and am wondering if I should cancel my colonoscopy.

    You’re not the only one. It seems more common than we know.
    A few people have mentioned it and myself too now.

    Just started taking Garden of Life Primal Defense Ultra because I had a round of antibiotics. I have taken about 3-4 pills over the course of two weeks. I keep forgetting I have them. BUT….. this week I took two and I have had gut distress (gassy with unusual odor, diarrhea, 911 bathroom situations, and slight, occasional nausea). Do you think it could be the probiotic?? Thanks for being here….. hopefully you still are!

      Hi Michele,

      Taking probiotics after antibiotics is typically a good move! But of course chat with your doctor about this.

      So it could be probiotic side effects, or it could be antibiotic associated diarrhea, or it could be something else. It’s hard to say. But if your doctor or health care provider says it’s okay, maybe you can pause the probiotics and see if anything changes.

      Often times after post-antibiotics there is diarrhea…but there is some research that taking antibiotics with probiotics at the same time can help prevent diarrhea:

    I have had issues with constipation for 15 years following a hysterectomy.
    Just this week after taking probiotics, given to me by my doctor, the first thing I do every morning is go to the bathroom. That and itself is a miracle. I do experience the gurgling and urgency, but I don’t mind at all! It feels wonderful to get rid of whatever was inside me. I see that so many people said that they experienced bloating. My experience has been just the opposite, and I’m very grateful!
