Can Probiotics Help with Histamine Intolerance or Make it Worse?
If you have been struggling with histamine intolerance; you have probably been looking for supplements that would help relieve the symptoms, like IBS, gas, and bloat. And most likely, you have tried some probiotics to help heal the gut and reduce histamine levels.
After all, histamine intolerance is primarily due to a lack of diamine oxidase (DAO), produced predominately in the gastrointestinal lining where our gut microbiota resides. So, it would make sense that probiotics that help to balance the gut microbiota and heal the gut would help to resolve your histamine intolerance.
Research on probiotics and histamine intolerance is evolving at this point. However, research shows that an imbalanced gut microbiota or dysbiosis plays a significant role in food intolerances, including gluten, histamine, tyramine, and glutamate.
Probiotics and prebiotics (food for the commensal bacteria) are essential in overcoming histamine intolerance as they can help rebalance the gut microbiota.
But what are the right probiotics is the question? Could some probiotics make your histamine intolerance worse?
Histamine Intolerance & Our Gut Microbiota
Every time we sit down to eat a meal, we expose our gut to toxins and endotoxins (toxins that the body produces during digestion).
When we think of toxic substances, food does not come to mind. But eating and the process of digestion is the most common exposure to toxic substances that we as humans experience.
Our microbiome helps protect us from these toxins, digest our food, deliver nutrients, and promote healthy metabolism of nutrients like vitamin B12. And helps to degrade and block histamine from foods during the digestion process.
More than 100 trillion commensal bacteria in our gastrointestinal tract or the gut lining play an essential role in our immune system and our digestion. The diversity and abundance of our gut microbes determine whether or not food is digested safely and efficiently, providing the best protection against endotoxicity.
When our gut microbiota becomes imbalanced, lacks diversity, or we have reduced bacteria due to antibiotics, toxins can pass through the body. When our gut microbiota becomes imbalanced, this can lead to a condition known as intestinal permeability or leaky gut.
Leaky gut leads to inflammation, the release of histamine, and a reduction in the DAO enzyme increasing histamine levels.
DAO functions in enterocytes or the cells of the intestinal lining. Here DAO degrades histamine from our food but there many different factors that can impact the production of DAO including an imbalanced microbiome. Courtesy of Histamine Intolerance – The More we know the Less We Know
How Does Gut Dysbiosis or Microbiome Imbalances Cause Histamine Intolerance?
A diverse and balanced microbiome is similar to a vegetable garden with few weeds. Weeds are an evitable part of any garden, but there are fewer vegetables if they overgrow and take over our garden.
The same goes with gut microbiota – some bacterial or yeast (Candida) strains can easily take over our microbiome. Candida and other molds are known histamine producers and often can be a “hidden infection” that we are unaware of.
Other bacterial infections that increase or produce histamine are:
- Candida – Yeast Overgrowth
- C. perfringens
- E. coli
- H. pylori
In most cases the bacteria are gram-negative bacteria that release a substance known as Lipopolysaccharides (LPS). High levels of LPS can cause a strong immune response, inflammation, and histamine release.
In addition to a robust immune response, a compound known as Zonulin will be released that loosens up the tight junctions in our intestinal lining, leading to leaky gut and histamine release.
Top that off, dysbiosis and leaky gut cause a reduction of DAO – the very enzyme you need to degrade histamine. There are many causes for low DAO with gut dysbiosis the number one cause.

Are There Probiotic Strains That You Should Avoid?
Yes, definitely. I learned the hard way on this one. Trying to experiment with making my own yogurt, I purchased a culture to make my yogurt containing Lactobacillus bulgaricus. Oops…
Lactobacillus bulgaricus is a common probiotic used in many popular yogurt brands, i.e., Fage. Always read the labels on yogurt and other fermented products to see what strains they are using. Avoid products that do not correctly list probiotic strains used in their products.
Probiotic strains that are commonly found in probiotic supplements that are histamine producers:
- Lactobacillus bulgaricus
- Lactobacillus casei
- Lactobacillus reuteri
- Lactobacillus brevis
- Lactococcus lactis
- S. thermophilus
Some of these strains can also produce other biogenic amines making your histamine intolerance worse. While you are beginning your healing process of resolving histamine intolerance, it is best to avoid these probiotic strains.
What Are the Best Probiotics for Histamine Intolerance?
Just like there are probiotic strains that promote histamine, there are strains that degrade histamine. Along with DAO which blocks absorption, these strains degrade and breakdown histamine. These are also commonly found in fermented foods and dietary supplements.
- Bifidobacterium infantis
- Bifidobacterium longum
- Lactobacillus gasseri
- Lactobacillus paracasei
- Lactobacillus rhamnosus
- Lactobacillus plantarum
- Lactobacillus salivarius
Using probiotic supplementation is a great way to improve your gut microbiota and resolve histamine intolerance. But don’t forget to add in the healthy foods that contain prebiotics to truly heal leaky gut and dysbiosis.
Some of the foods that high in healthy prebiotics like apples, onions, garlic, leeks, asparagus and even barley are all high in prebiotics.
Root vegetables like beets and sweet potatoes provide the gut bacteria with the food that the good bacteria need to flourish.

This probiotic contains the three lactobacillus strains that are histamine degraders making it an excellent choice to help support a healthy microbiome and help to resolve histamine intolerance.
Can Soil Probiotics Help Heal the Gut and Help Overcome Histamine Intolerance?
Unlike most probiotic strains that are extracted from fermentation, soil probiotics or spore-forming bacilli come from the soil where they were initially discovered.
Now you are probably thinking, who wants to eat soil or dirt to get healthy bacteria for the gut??
We naturally get spore-forming bacilli from eating raw vegetables, especially those from our gardens that have not been overwashed.
The most significant advantages to soil probiotics are that they can easily survive the extreme acidity of the stomach, tolerate bile salts from our digestion, and do not have to be refrigerated.
They have also been found to colonize in the gut microbiota – in other words, they more readily stick around and help balance our microbiome.
Along with their ability to “weed” our microbiome garden, they have been found to heal the gut lining, thereby reducing food intolerances like gluten and histamine.
Soil Probiotics – Bacillus spp
- Reduce Endotoxicity
- Increase Protective Gut Mucus
- Increase Short Chain Fatty Acids
- Better Digestion – Nutrient Absorption
- Rebalance the Microbiome
- Reduce Autoimmune Flare-ups
Because histamine intolerance originates in the gut, soil probiotics can help heal the gut and get down to the underlying cause of your histamine intolerance.
The strains of soil probiotics that research shows has the greatest benefits and found in supplements are:
- Bacillus indicus
- Bacillus subtilis
- Bacillus coagulans
- Bacillus licheniformis
- Bacillus clausii
Since most soil probiotics are not histamine producers and have the biggest potential to heal the gut, they not just help you overcome histamine intolerance but get down to the cause of your food intolerances.

Can Prebiotics Help You Overcome Histamine Intolerance?
The best way to balance and support a healthy microbiome is to make sure your diet has adequate fiber to help feed the probiotic strains. Probiotic strains will not stick around and set up residency if they don’t have a hospitable environment. And that means having food so that they can flourish and grow.
Prebiotics are fiber or sugars like oligosaccharides that help the strains adhere to and colonize your gut.
Not only does fiber helps feed the beneficial bugs, but fiber, like pectin, lowers inflammation, and allergic reactions, especially in allergic asthma. And that means they help to reduce the release of histamine!
But perhaps the most significant benefit certain fibers like resistant starch have is that they help promote short-chain fatty acid production (SCFA). SCFA, like butyrate, is fuel for the colon cells and helps to reduce inflammation.
Reducing inflammation and helping to support a healthy and balanced microbiome will lower histamine release, increase DAO enzyme, and help heal the gut.
Check out my guide for resistant starch.
If you struggle with getting enough fiber in your diet, Designs for Health, Paleo RS Fiber is an excellent supplemental fiber.
Other prebiotics, like oligosaccharides, is a form of sugar and are very effective at helping rebuild your gut lining found in Just Thrive Precision Prebiotics.

Are there Tests that Help You to Choose the Right Probiotic to Overcome Histamine Intolerance?
Rebuilding and balancing the gut microbiota can be difficult with histamine intolerance since most foods containing probiotic strains, like fermented foods, are high in histamine.
Top that off, most foods rich in healthy fiber that supports the microbiota, like legumes, are high in histamine.
That is why you may have to supplement with probiotics and prebiotics while you heal your gut and overcome histamine intolerance.
How do you know what will work with so many different probiotics? The first step is to ensure you are not taking probiotics or consuming foods containing histamine-producing probiotic strains.
But can you test to see what strains you need to supplement with? Microbiome testing can give you an idea of what is out of balance, your diversity, and abundance – all key to balanced gut microbiota. Some microbiome testing like VIOME comes recommended and tailored probiotic supplements.
My other favorite microbiome test is Gut Health Test by Thorne which will provide suggestions for probiotic strains and the best fiber you need to heal your gut.
