Is it possible that your probiotic could be making you sick? Sadly, it is! In this post about low-histamine probiotics, I'll share what histamine is and what that has to do with probiotics, and why your probiotics might not be doing you any favors.
Probiotics are something that's commonly accepted as being good for everyone. Gut health is crucial for overall health, and probiotics are beneficial bacteria that help to recolonize the gut to restore balance. So one would think that taking probiotics is always a good thing. Right?
Wrong.

For some people, taking probiotics could be a completely bad idea.
That is, if they are taking the wrong kind of probiotic.
Histamine intolerance is something that we've talked about on the blog before. In this post we talked about what histamine intolerance is, and in this post we talked about how to deal with a histamine intolerance, or histamine allergy.
One thing that wasn't mentioned, however, is the role that probiotics play in histamine intolerance treatment.
Yikes—Could I Have Histamine Intolerance?
Around Christmas of this past year, I kind of “fell into” a detox. Just in case you were wondering, detox isn't the best idea during the Holiday Season. I don't recommend it. However, the whole thing led to some very interesting information.
It all started with my taking a heavy-duty liquid fermented superfood probiotic. I'd taken it years ago, and it had clearly done some heavy duty work on my gut. This time, however, I felt I needed to get out of my current probiotic rut and give that product another go. It went well for awhile, but then the reactions got a little intense. They subsided, but then resurfaced elsewhere, and I was pretty scared that I was histamine intolerant.
So I plunged into researching histamine intolerance online and was determined to figure out what I could do about it.
One of the recommendations that I found was to get on a low histamine probiotic so as to recolonize the gut without inflaming the already problematic condition.
What Is Histamine?
We covered quite a bit about histamine in this post, but here's a quick review.
Histamine is a chemical produced by your body that is involved in your immune system, proper digestion, and central nervous system during immune responses. It sends messages from your body to your brain and is a component of stomach acid.
Stomach acid is very important to overall health which you can an example of in this post about stomach acid and rosacea.
But the role of histamine that is central to our discussion today is how histamine is involved with the immune system.
You mostly like are familiar with the word “histamine” as it being a part of the word “anti-histamine” hose substances that one takes when allergies are being a bother. Histamines are alerting your body of a real (or mistaken) offender and cause an inflammatory response. And it causes this all over the body.
If your body can't break down the histamine well or fast enough, you end up with histamine intolerance.
That leads to the problems outlined in this post on histamine intolerance, but basically you can have all kinds of symptoms including things that one would typically associate with allergies, such as:
- itching
- sneezing
- rashes
- nasal congestion
- sinus pressure
- headaches
- fatigue
- insomnia and more.

Histamine and Probiotics
Basically, if you have a histamine intolerance issue, the last thing that you want is to be taking probiotics that make more histamine. If you do that, instead of getting healthier, you could be exacerbating an underlying health issue and well–your probiotics could be making you sick.
And if you are making your own water kefir, Homemade Sauerkraut, and more, that may or may not be a good idea depending on your issues with histamine.
Additionally, there are some probiotic strains that have been shown to be helpful in reducing the histamine response.
According to the research that I've done, the following are various probiotic strains and the effect that they have on histamine levels. Of course that research could change in the future.
Histamine Raising Probiotic Strains
- Lactobacillus bulgaricus
- Lactobacillus casei
- S. thermophilus
- Lactobacillus delbrueckii
- B Lichenformis – appears to raise histamine
- Lactobacillus helveticus (while this does raise histamines, it is known to reduce anxiety and ammonia, and restores cognitive function)
Histamine Lowering Strains
- Bifidobacterium infantis
- Lactobacillus gasseri
- Lactobacillus rhamnosus
- Bifidobacterium longum
- Lactobacillus plantarum
- Bifidobacterium breve
- Lactobacillus salivarius
- Bifidobacterium lactis
- Bifidobacterium Bifidum
- Lactobacillus reuteri**Lactobacillus reuteri is kind of in a class by itself. Many place it in the “histamine producing” category, but interestingly enough, it doesn't belong there. Lactobacillus reuteri does, in fact, cause histidine to convert to histamine, but this histamine raises cAMP which actually reduces the inflammatory response. Fascinating! I therefore put it in the “histamine reducing” class due to this aspect. (3)
Lactobacillus plantarum does not appear to have an effect on histamine, but it does lower and/or inhibit tyramine and putrescine.
Histamine Neutral Strains
- Lactobacillus acidophilus
- Lactobacillus Lactis
- Lactococcus Lactis
Bacillus Coagulans
It's possible that other strains might end up have their own special section as well in the future, as more is known about them, but Bacillus Coagulans appears to be a bit unique and I had trouble sorting this strain out.
There is research stating that the B. Coagulans SL5 causes increased histamine, but the B. Coagulans in 2 of the gut health products that I recommend below is MTCC 5856, which is a different strain. In fact, Lactospore (MTCC 5856) is used in some supplements that are made to support those with histamine issues.
Furthermore, there is also this research showing that B. Coagulans is helpful in allergic situations on a number of fronts.
Not Histamine Lowering But….
The following strains aren't typically referred to as being “histamine lowering” strains, but some research shows that they might support the body in ways that would benefit those struggling with histamine intolerance
- Saccharomyces-Boulardii.
There are a number of studies on its effectiveness in treating gastroenteritis. Some researchers have linked this condition to high histamine/mast cell issue. So possibly this strain could be a good support.
There are some reports apparently about this yeast causing histamine issues in some people, but it has been used for detoxifying gliotoxin and apparently increases DAO production which means it should help with histamine issues. - L. Paracasei has been shown to possibly help with leaky gut or allergies.
- L. Casei Shirota
Although L. Casei has been shown to raise histamines, L. Casei Shirota has been shown to modulate histamine levels. - Lactobacillus Crispatus has been shown to have anti-allergenic effects.
How to Sort All of This Information Out
This information is complicated but basically, if you're trying to avoid probiotic strains that might make histamine issues (and inflammation) worse, you want to avoid histamine-raising strains and get probiotics that have histamine-lowering strains in them. However, if they have histamine-neutral strains in them that's fine too.
So, in order to work on mine and my son's possible histamine issues, I went a hunt to find probiotics that had the strains that we wanted but didn't have the problematic strains.
It was quite a job, trying to figure out what to buy with all of those “lacto this” and “bifido that” words popping out at me. However, I did find some products that were just perfect for what we were looking for.
Where to Buy Low-Histamine Probiotics
I buy my supplements in several places. One of my favorite places to shop is Iherb. They have fast service and very good prices.
Some of the brands listed below, like Metagenics, claim that their product is fine when not refrigerated during shipping. If you're concerned about that, please take care to buy them either in a store where they are refrigerated or have them shipped with a cold pack.
Low-Histamine Probiotic Single Strains
Here are some individual strains of bacteria that should be helpful for histamine intolerance.
- Klaire Labs Ther-biotic Factor (Lactobacillus rhamnosus).
- Thorne Flora Pro LP or
- Jarrow Formula’s Ideal Bowel Support (Lactobacillus plantarum).
Most natural practitioners who recommend rotating between different kinds of probiotics so as to populate the gut with different strains. So—purchasing several or all of the above varieties and rotating between them would be a great idea to help you do just that.
Low Histamine Probiotic Blends
Personally, I think a blend is a better option than a single strain since you are getting more beneficial “bugs” into your gut. It's like facing the bad guys with a multi-faceted assault instead of a single strategy.
1. Smidge (Formerly GutPro)
Recently, our family started using Smidge (formerly GutPro). It's a probiotic unlike many others in that it's super concentrated. It's not cheap, but it lasts a REALLY REALLY long time.
Just a teensy bit on a teensy spoon is all you need.
I have tried so many probiotics over the years, and with many of them, I feel NOTHING. But with Smidge? Gurgle gurgle gurgle…..something is happening for sure!
Important: make sure to get the teensy stainless spoons that Organic3 has if you get this product because you are going to need them!
Depending on how you use the probiotics, you might want to order two sets of spoons so if one is dirty you have another set at the ready. You absolutely must not use the spoons for these probiotics if they are damp at all, as that will compromise the bacteria. Wet bacteria, in this case, is dead bacteria.
2. Seeking Health Probiota HistaminX
This blend was created for the express purpose of having a blend for those with histamine intolerance. Some have said that this probiotic blend has really helped with their histamine issues, both with probiotics and to other foods. The company has a great Subscribe and Save program so you can save money. Some people use this product alongside the company's Histamine Digest.
More Low-Histamine Blends
Here are some blends of various strains that should not exacerbate histamine intolerance and might even help heal it.
Can You Recover From Histamine Intolerance?
Good question.
This is a complicated topic, but an important one.
Here are some things that correspond with histamine intolerance:
- celiac disease
- food intolerance
- leaky gut
- digestive issues
- diet high in histamine
- and many others
All of the above can be linked to a gut infection called h pylori. Interesting.
So, my thinking is, if you address the above, the histamine intolerance might just go away.
Basically, instead of avoiding things that are supposed to be good for you long term, find out why your body isn't tolerating things and address the root cause.
My Experience With Histamine Intolerance
I personally found it to be true that histamine intolerance isn't a life sentence.
At one point, I worked with a practitioner due to multiple issues, but I was reacting badly to eating ferments. She recommended the low-histamine diet, but the thought of it was horribly stressful. Imagine freezing everything you eat (that has to be cooked from scratch), no vinegars, no collagen, and more.
I finally got a diagnosis of Lyme disease, and I started working on my health in new ways using supplements, addressing underlying infections, PEMF, red light, brain retraining, and phototherapy patches.
Now I can mostly eat ferments, grass-fed sausage, cheese, and collagen without major problems. In fact, I even ditched my life-threatening food allergy to egg.
The moral of the story is to never give up. Work on your health even when it seems hopeless, and you will likely see progress, including progress that no one thought was possible.

What about Udo’s Children’s blend probiotics.?
You would have to check the ingredients against those in this post – were you able to do that?
I take Kyodophilous 9, anything that has B. Infantis in it usually helps. I have also taken Megaflora from Megafood without an issue.
There is one called Gutpro that is low histamine.
Probiotics are commonly accepted as being something that is good for everyone. What about Total synergy adult premium blend Probiotics . It helps to create perfect balance in your gut.
I would just compare the ingredients to the ones in the post. Thanks for reading!
I have what the Drs say “IBS” and the Dr said he was giving me that diagnosis because he didn’t know what was wrong. He admitted it when all the tests came back with nothing. Now I an having symptoms of Interstitial Cystitis. My health is poor and I am sick all the time, sometimes in bed with pain for weeks, with multiple visits to ER, Urgent Care, Drs, tests… All telling me I’m “fine”. Every food I eat bothers me and there are periods where I go 2-3 days without sleep. I’ve been to alternative Drs, too, and the keep shoving probiotics down me. I never get better. Always worse. My 23andme report does show several SNPs that would create a histamine overload. Maybe I should refuse all probiotics forever. But how do I heal my gut without them? Sigh. What I need I can’t have cuz it makes me sicker in other areas of my body. I’m 35 and I can’t be a mother to my 3 and 5 year old. I need hope. I don’t have anymore. Plz pray for me. ?
I am so sorry! I will pray for you right now. The probiotics in this post have been shown in tests to possibly help the histamine issues. Have you ever worked with a natural practitioner? I guess the thinking is that if you are causing more damage and inflammation then it isn’t the best choice? Some people say that using prebiotics is a good idea but I haven’t done much research into them.
check for infections, and most importantly LYME. Lyme is difficult to diagnose though and the testing is terrible. IF yo’rer serious, use igenex , pay the money to know if you have lyme or not.
Check our MegaSpore.
I have looked at that. Some practitioners have concerns about introducing spores into the gut and I haven’t seen data on any of their strains re: histamine issues. Have you?
What about Prescript Assist? Any thoughts on that one? Thanks!
I also have a Jarrow Formulas Saccharomyces Boulardii+MOS, which is a S. cerevisiae strain. Would you possibly have any info on that? Thank you for taking the time to tell us about this! I am pretty sure this is one of the issues I am dealing with and am trying to get as much info as I can.
Good question. I just added something about that strain to the post. You are so welcome!
Hi there. You should compare the ingredients with those in the post. It looks like they have a lot of strains that weren’t in the research that I did.
I have histamine issues and my functional Med doc has me taking that one and megaspore. I have done fine with them.
Interesting….how does Dr. Ohhira’s original and professional products measure up? Think same ingredients but one is fermented longer.
It appears that there are quite a few high histamine strains in them.
Where would you place Cuturelle Health & Wellness formula containing Lactobacillus GG? Thank you.
I think it has multiple histamine-causing strains if I remember correctly.
Thank you for doing this research! I’ve also been suspecting histamine intolerance and was wondering if any of my supplements could be contributing to symptoms I get. I’ve had rashes that come and go for nearly ten years and thought it was all due to candidiasis and leaky gut. My allergies are mostly to food. For several months now I’ve been breaking out with severe itching, hives, and eczema like never before. I also get left side headaches, fast heart rate, anxiety, irritability, and can’t eat or sleep. Even when I stop eating for a day I still itch and can only get relief by using otc oral antihistamines in excess. I tried mega dosing with vit. c but it didn’t help. I’m going to start a food diary now and try some histamine suppressors like quercetin. Thank you for sharing your experience and info. to help others with these issues.
You might want to read the book Never Bet Against Occam. I went to my doctor because I had extreme insomnia and she put me on histamine blockers and suggested I read that book. It’s so outside the gluten free, probiotic, clean whole food and supplements track that I’ve been following for years now – and that my doctor supports, but I think it’s ground breaking, scarily accurate and I am finding relief. Once I read the book I realized that I have a lifetime of symptoms that are very in line with the case studies outlined. And your symptoms seem similar. Best of luck.
What if you take a probiotic that has almost all the strains listed. I take iflora from sedona labs. I figured the more strains the better, but am now wondering. Would the low histamine outweigh the high histamine ones? I had taken this probiotic before and felt that it improved my mood and energy. I had to quit taking it due to finances, and recently started taking it again, but failed to notice a huge change like before, especially in the energy department. However, that could be due to something else, I have like 1,000 things wrong with me so that could be it. I can honestly say tho that probiotics have helped my battle with candida. My hands and ears would itch tremendously, as well as “other” areas. As long as I keep up with my probiotics the itching is gone.
I would think that the high strains might outweigh the low, but if one has histamine intolerance issues then it would be best to focus on the ones that will actually support your body and possibly help the condition. Do you know that you have histamine intolerance?
