Headaches, eczema, hives, congestion, fatigue, sleep issues, brain fog, mood swings, anxiety, and so on. Sounds familiar? Are you dealing with chronic unexplained symptoms? You may be dealing with histamine intolerance. Histamine intolerance is a relatively common health issue caused by a build-up of histamine, yet we don’t talk about it enough.
In this article, I want to go over everything you need to know about histamine intolerance. You will learn what histamine and histamine intolerance are. You will understand the symptoms of histamine intolerance. I will discuss the importance of reducing your histamine bucket. You will understand the difference between allergies and histamine intolerance.
I will explain the difference between mast cell activation syndrome and histamine intolerance. You will understand the potential underlying cause of histamine intolerance. I will share a list of high-histamine foods, histamine-liberating foods, DAO enzyme-blocking foods, and low-histamine foods. Finally, I will share my top recommendations for histamine intolerance. Let’s get into it.
What Is Histamine?
Histamine plays a very important role in your body. It’s a chemical that supports your immune system by getting rid of allergens that it encounters. To protect you from allergens and toxins, your immune system releases histamine and other chemicals. Depending on the type of allergen attacking your system, histamine acts on various areas of your body, including your nose, throat, lungs, skin, eyes, or digestive tract. This action will result in symptoms of allergy.
Besides supporting your immune system and protecting you from allergens and other foreign substances, histamine also aids your gastrointestinal health. It supports your digestion by releasing hydrochloric acid.
Histamine also serves as a neurotransmitter. It allows communication between your brain and other parts of your body. Thus, it is critical for your brain, neurological, and mental health (1).
What Is Histamine Intolerance?
Histamine is clearly an essential chemical you need for immune, digestive, brain, neurological, and mental health and well-being. However, too much of the good thing can become a problem. This is the case when it comes to histamine.
Having too many chemicals triggering a response or histamine intolerance can cause chronic histamine release and chronic symptoms. Too many high-histamine foods, environmental toxins, stress, and other factors can lead to too much histamine associated with an increased release of histamine in your body. If your body has too much histamine and is unable to deal with it, it will lead to histamine buildup. This histamine buildup, called histamine intolerance, can affect your entire body and cause widespread symptoms (2, 3, 4, 5).
DAO Enzyme and Histamine Intolerance
There are two primary enzymes that are involved in breaking down histamine: histamine N-methyltransferase (HNMT) and diamine oxidase (DAO). Out of the two, DAO is the primary enzyme responsible for breaking down dietary histamine (6).
DAO enzyme deficiency can lead to histamine intolerance (7, 8). If your body is experiencing issues producing enough DAO enzymes, your DAO enzyme levels are too low, or the proper function of DAO enzymes is inhibited, your body will likely struggle to break down excess histamine. You could end up with symptoms of histamine intolerance.
There are a number of things that can inhibit DAO activity and contribute to histamine intolerance. One of the most common causes is leaky gut syndrome or increased intestinal permeability. Since DAO enzyme is made in your gut, compromised gut health can lead to DAO enzyme deficiency and related histamine intolerance (9).
Genetics, specifically certain genetic mutations or single nucleotide polymorphisms (SNPs), can result in genes with a lower ability to break down histamine (10, 11). Since estrogen can activate histamine release from your mast cells, estrogen dominance can also lead to increased histamine release. Excess histamine from estrogen dominance can make it challenging for your body to keep up and make enough histamine metabolising enzymes (12).
Finally, there are also certain foods, drinks, and medications that can block the production of DAO or inhibit its activity. In a later section, I will go over the main DAO enzyme-blocking foods (13). In this article, you can learn more about the medications to avoid with MCAS. However, if you are on any medication, I recommend speaking with your doctor to determine if any of them interfere with DAO enzyme production, mast cell activation, or histamine intolerance.
Symptoms of Histamine Intolerance
Histamine intolerance is essentially a buildup of histamine. Histamine intolerance can affect your entire body and can lead to widespread symptoms.
Symptoms of histamine intolerance may include:
- Headaches and migraines
- Eczema, dermatitis, acne, and other skin issues
- Hives
- Fatigue and sleep issues
- Red eyes
- Dizziness or vertigo
- Heart palpitation or racing heart
- Brain fog, confusion, memory issues
- Irritability and mood swings
- Anxiety or panic attacks
- Blood pressure changes
- Allergies
- Asthma
- Congestion or runny nose
- Acid reflux, bloating, diarrhea, and other digestive symptoms
- Abnormal menstrual cycle and premenstrual syndrome (PMS)
Your Histamine Bucket
When it comes to histamine intolerance, I like to talk about the histamine bucket. Imagine a bucket. It can hold a certain amount of water. If you put less water into the bucket than it can hold, everything will be fine. Once you start reaching the top, it becomes riskier. If you pour more water than it can hold, it will spill and cause a mess.
It’s the same with histamine. Your body can only tolerate so much histamine. Your histamine bucket refers to your body’s limited capacity for histamine. If you have more histamine in your body than it can break down, it will lead to uncomfortable and potentially chronic symptoms. When you exceed your body’s histamine capacity or overspill your histamine bucket, histamine-related symptoms, and health issues can become more difficult to manage. Low levels of DAO enzyme can lower your tolerance to histamine, which means you have to be even more careful.
Eating too many high-histamine foods is one way to fill up your histamine bucket and experience symptoms of histamine intolerance. However, it’s not the only way. Other factors that can lead to histamine release and histamine intolerance symptoms may include:
- Stress, including emotional and physical stress, acute and chronic stress
- Gut health issues, including gut microbiome imbalance and leaky gut syndrome
- Environmental factors, including environmental toxins
- A poor diet filled with highly refined processed foods, food allergens, food sensitivities, and high-histamine foods
- Nutritional deficiencies
- Hormonal imbalances
- Certain medications, including over-the-counter, prescription, and illegal drugs
What Is the Difference Between Allergies and Histamine Intolerance?
We already talked about how histamine helps to fight allergens and toxins. So, how is histamine intolerance different from histamine intolerance? Great question.
When your body comes in contact with seasonal allergies, pet fur, dust mites, mold, food allergens, or other allergens, you will experience what we call histamine reactions. Symptoms of histamine reactions can include redness, itching, skin rashes, runny nose, sneezing, coughing, watery eyes, or digestive complaints (14, 15).
As you see, these symptoms can be similar to and overlap with the symptoms of histamine intolerance. So it can be difficult to distinguish between the two at first glance. To understand the difference, we have to understand the triggers and mechanisms behind the symptoms.
Allergies and histamine intolerance are not the same: their triggers and underlying mechanisms are different. An allergy is a reaction from your immune system to a substance, such as pollen, animal dander, dust, or food. On the other hand, histamine intolerance refers to a build-up of histamine in the body, contributed to by allergy but not solely due to that.
Identifying your triggers and looking at the underlying mechanisms behind your symptoms can help you identify whether you are experiencing symptoms of allergy or histamine intolerance. Allergy testing is a great option to identify allergies. They are especially helpful when it comes to seasonal allergies, pollen, dust, allergies to pets, and similar issues. When it comes to food, keeping a food journal, trying an elimination diet, and watching your body’s reaction to food can be better at identifying food sensitivities than blood tests.
If the underlying cause is histamine intolerance, a low-histamine diet and lifestyle changes should help with your symptoms. Working with a functional medicine practitioner like myself can help you figure out if you are dealing with histamine intolerance beyond allergies. Histamine intolerance often comes along with other chronic complaints or underlying issues. Functional medicine can help you uncover all these issues and address the root cause of your symptoms.
Mast Cell Activation Syndrome vs Histamine Intolerance
Another issue that may be similar to or overlap with histamine intolerance is mast cell activation syndrome (MCAS). Your mast cells are white blood cells that store inflammatory mediators or chemicals, including histamine. They can be found in your respiratory tract, digestive system, urinary tract, skin, and blood.
When your body encounters an allergen, environmental toxin, infection, stress, or another trigger, it will result in mast cell activation. When your mast cells are activated, they will release histamine and other chemicals to fight off the invaders and protect you.
While mast cells are important for your health, dysregulated or overactivated mast cells can cause issues. MCAS refers to a condition when your mast cells release too much histamine and other chemicals leading to widespread symptoms (16, 17).
Triggers of mast cell cell activation include allergens, mold, heavy metals, toxins, chemicals, infections, viruses, medication, and alcohol. If you have MCAS and encounter these triggers on a regular basis, it can lead to constant mast cell activation and related histamine and chemical-release.
When it comes to viruses, I want to emphasize that viruses are one of the potential triggers of mast cell activation. This includes COVID-19 as well. In fact, mast cell activation syndrome may play a role in long-COVID symptoms and should be address to support recovery.
Symptoms of MCAS may include:
- Rashes
- Hives
- Itching
- Headaches or migraines
- Chest pain
- Heart palpitations
- Low blood pressure
- Weakness
- Dizziness
- Weight changes, including rapid weight loss or weight gain
- Digestive trouble, including diarrhea, nausea, and vomiting
- Loss of appetite or low appetite
- Fatigue
- Anxiety
- Vision changes
Symptoms of MCAS and histamine intolerance can be similar, but the two conditions are not the same. MCAS refers to the overactivation of mast cells which leads to the release of histamine and other chemicals and related symptoms. Histamine intolerance means that your body has a buildup of histamine because it cannot break down excess histamine from a high-histamine diet and other high-histamine lifestyle factors.
While MCAS can lead to histamine intolerance, it might not lead to histamine intolerance in all people. This is because of the other chemicals mast cells store and release when triggered. There are over 200 of them, and just like histamine the others can cause inflammation and symptoms. Histamine intolerance doesn’t lead to MCAS. Some people have both conditions, others only struggle with one.
If your body has too much histamine and can’t handle it, it can result in histamine intolerance. This usually happens due to a high-histamine diet. However, stress, poor sleep, environmental toxins, certain medications, and other factors may add to your histamine bucket as well. If your body has trouble breaking down the extra histamine, it will lead to histamine build-up and histamine intolerance. Working with a functional medicine practitioner can help you figure out if you are dealing with histamine intolerance, MCAS, both, or any other chronic health issues.
Causes of Histamine Intolerance
There are several underlying issues that may increase your risk of histamine intolerance.
Mast Cell Activation Syndrome
As we discussed in the earlier section, mast cell activation syndrome means that your mast cells are overly active, get very sensitive to triggers, and release an increased amount of histamine, resulting in a variety of symptoms. MCAS is a common underlying issue behind histamine intolerance. However, not everyone with histamine intolerance has MCAS, and not everyone with MCAS develops histamine intolerance (16, 17).
Leaky Gut Syndrome
A healthy gut lining has tiny little holes that allow nutrients to pass through but block toxins and larger food particles. Chronic inflammation, gut microbiome imbalances, an inflammatory diet, stress, and environmental toxins exposure can make these tiny holes bigger. At this point, larger food particles, toxins, and infections can pass through. This means you have developed leaky gut syndrome. Leaky gut syndrome may reduce your body’s ability to produce enough DAO enzymes (9). It might also increase chronic inflammation, which can lead to increased mast cell activation and histamine release.
Gut Infections
Gut infections often play a role in histamine intolerance. These gut infections may include Helicobacter pylori (H. pylori) infections, small intestinal bacterial overgrowth (SIBO), small intestinal fungal overgrowth (SIFO), candida overgrowth, and parasites. Your gut is full of mast cells. If you are dealing with a gut infection, it can lead to increased mast cell activation and histamine release, which may result in histamine intolerance. Since gut microbiome imbalances can increase the risk of leaky gut syndrome, it can also lead to reduced DAO enzyme action, further increasing your risk of histamine intolerance symptoms (9, 18, 19, 20).
Inflammatory Bowel Disease
Inflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis, are autoimmune diseases that affect your gut and cause digestive symptoms. Due to their inflammatory effects on your gut, they can reduce DAO enzyme production and may also increase mast cell activation and histamine release (9, 21).
Gluten Intolerance
Gluten is a protein found in a variety of grains, including wheat, barley, rue, semolina, farro, farine, durum, malt, kamut, and graham. It hides in many bread and pastry products, pasta, crackers, croutons, cereal, beer, dressings, and other food products. Gluten is not only highly inflammatory, but it can also increase your risk of leaky gut syndrome. Leaky gut is a common underlying problem behind histamine intolerance and chronic inflammation, which can also increase mast cell activation and histamine release (9, 22).
Nutrient Deficiencies
Certain nutrients, including vitamin C and copper, are critical for DAO enzyme production and function (23, 24, 25). Vitamin B6 also helps to support DAO in breaking down histamine. It also makes copper more bioavailable, helping DAO enzyme action (26, 27). Low zinc levels are also commonly connected to poor copper levels, causing issues (28). Thus, poor levels of these nutrients may all be linked to DAO enzyme deficiency. Moreover, nutrient deficiencies might also increase the risk of inflammation, poor immune health, and gut health issues, which can all increase the risk of mast cell activation and histamine release.
Genetic Mutations
We have already touched on genetic mutations briefly in the DAO enzyme section. Genetic mutations that reduce DAO enzyme production may increase the risk of histamine intolerance, as you won’t have enough DAO enzymes to break down histamine. However, there are other genetic issues to pay attention to. There are a variety of genetic mutations that can play a role in mast cell activation and histamine intolerance (29).
HNMT is a gene that’s necessary to process histamine and regulate the breakdown of histamine (30, 31). S-Adenosyl-L-methionine (SAMe) is a cofactor of HNMT that helps the breakdown of histamine (32). The Monoamine Oxidase (MAO) enzyme also helps to break down histamine (33). Methylenetetrahydrofolate reductase (MTHFR) is a gene that helps the methylation process (34). Proper methylation is necessary for the processing, breakdown, and elimination of histamine. Thus, genetic mutations that affect HNMT, SAMe, MAO, DAO, and MTHFR can all increase the risk of histamine intolerance.
Medications
Certain medications may interfere with DAO enzyme production and cause DAO enzyme deficiency. These medications include certain antidepressants, non-steroidal anti-inflammatory drugs (NSAIDs), antihistamines, histamine-blockers, antiarrhythmics, and immune modulator medications. Some medications may be problematic by increasing mast cell activation and are not appropriate if you have MCAS (35, 36, 37).
Again, I recommend this article for an overview of the medications to avoid with MCAS. However, if you are on any medication, I recommend speaking with your doctor to determine risk / benefit and if any of them interfere with DAO enzyme production, mast cell activation, or histamine intolerance.
Food and Histamine
Some foods are higher in histamine, and you may have to avoid or limit them if you have histamine intolerance. Other foods are lower in histamine, and you can eat them freely, even with histamine intolerance. Histamine-liberating and DAO enzyme-blocking foods may also be a problem with histamine intolerance.

Recommendations for Histamine Intolerance
Though symptoms of histamine intolerance can be chronic and uncomfortable, they can be improved through some simple dietary and lifestyle strategies. Here is what I recommend to improve your symptoms of histamine intolerance.
Follow a Low-Histamine Diet
If you suspect that you are dealing with symptoms of histamine intolerance, I recommend starting out with a low-histamine diet for 3 to 4 weeks with plenty of anti-inflammatory, nutrient-dense, low-histamine foods. Avoid high-histamine foods that can trigger histamine release, histamine-liberating foods, and foods that may act as diamine oxidase or DAO enzyme blockers. Additionally, avoid inflammatory foods, such as refined sugar, refined oil, artificial ingredients, gluten, heavily processed foods, and junk food.
Eat plenty of low-histamine, anti-inflammatory, nutrient-dense whole foods, such as greens, vegetables, herbs, fruits, eggs, pasture-raised poultry, grass-fed beef, and wild-caught fresh fish. For patients in my clinical practice, this diet change on its own has oftentimes resulted in marked improvement in symptoms. You can use the food list in this article and use this article as a guide.
Reduce Your Histamine Bucket
Besides high-histamine foods, other factors can contribute to your histamine diet, so following a low-histamine diet may not be enough to reduce your histamine-related symptoms. I recommend decreasing your histamine bucket by paying attention to other lifestyle and environmental factors. Avoid medications, chemicals, environmental toxins, heavy metals, and other irritants that may trigger histamine release. Reduce your stress and anxiety. Exercise and move your body regularly. Improve your sleep.
Try Quercetin
Quercetin is a powerful flavonoid that can also help to naturally lower histamine levels and the allergic response. Quercetin can be found in a variety of plant foods, including blueberries, cranberries, cherries, grapes, black currant, black plums, pepper, cruciferous vegetables, cabbage, romaine lettuce, kale, asparagus, snap pea, sprouts, olive oil, and various herbs. You will likely benefit from eating quercetin-rich foods. However, I also recommend taking a quercetin supplement if you are dealing with symptoms of histamine intolerance (38).
Improve Your DAO Enzyme Levels
DAO enzymes help to break down histamine in your body. If your body is not producing enough DAO enzymes, it won’t be able to break down excess histamine. This can lead to histamine buildup, histamine intolerance, histamine reactions, and histamine-related symptoms.
Certain vitamins and minerals, including vitamin B6, vitamin C, zinc, and copper, play a role in the production and function of DAO enzymes. Deficiencies in these micronutrients may increase the risk of low levels of DAO enzymes. On the other hand, getting enough of the micronutrients through food and supplementation may help to improve your DAO enzyme levels and functions (39, 13).
Try Mast Cell-Stabilizing Foods and Supplements
Since mast cell activation is one of the potential underlying issues behind histamine intolerance, stabilizing your mast cells may help to improve your health. Try foods that can help to stabilize your mast cells, including watercress, moringa, chamomile, Thai ginger, apples, Brazil nuts, peaches, nettle, onion, fibre-rich foods, and quercetin-rich foods (40, 41, 42, 44, 45, 46, 47, 48, 49, 50, 51, 52). Using vitamin C and vitamin B6 may also support DAO enzyme action (53, 54, 55). I recommend using supplementation with natural antihistamines and mast cell stabilizers, such as quercetin, resveratrol, curcumin, nettle leaf, and luteolin (56, 57, 58, 59, 60, 61, 62). DAO enzyme may be helpful (63, 64, 65, 66, 67, 68, 69).
Consider Intravenous Vitamin C
Vitamin C offers immune-boosting and anti-inflammatory benefits that can help to call down your mast cells and reduce histamine intolerance. Eating foods rich in vitamin C and taking vitamin C supplements orally is fantastic. However, using higher does of vitamin C in an intravenous (IV) may be more effective. In a recent study, 7.5 g of vitamin C administered intravenously in 89 patients with allergies or upper respiratory infections caused a significant reduction in serum histamine (70). I’ve written about the benefits of IV nutrient therapy in this article and I offer intravenous nutrient infusions at my practice.
Improve Your Gut and Try a 7-Day Histamine Gut Reset
Gut microbiome imbalances, leaky gut syndrome, and other gut health issues are potential underlying problems behind histamine intolerance. Since DAO enzymes are mainly made in your small intestines, improving your gut health is also critical for supporting DAO enzyme levels and functions.
You may benefit from improving your gut flora. Unfortunately, probiotic-rich fermented foods are high in histamine and are not appropriate for histamine intolerance. However, probiotic supplementation can help. If you are experiencing symptoms of histamine intolerance, you want to be careful with probiotics as well. Choosing the right strains can reduce the risk of histamine reactions and support your recovery.
If you have histamine intolerance, you want to avoid Lactobacillus casei, Lactobacillus Bulgaricus, Streptococcus thermophilus, Lactobacillus delbrueckii, and Lactobacillus helveticus. Look for probiotics specifically designed for people with histamine intolerance. Specific probiotics that may be great for histamine intolerance include Bifidobacterium strains, Lactobacillus rhamnosus, and some strains of Lactobacillus (71, 72, 73, 74). This article can help you select the right probiotics.
Of course, a gut-friendly, nutrient-dense, anti-inflammatory diet is also important. Some people may benefit from digestive enzymes to support digestion and the absorption of nutrients. If you are dealing with environmental toxins, heavy metals, or mold, you may benefit from a detoxification protocol as well. You can learn more about detoxing in this article.
If you are dealing with SIBO, SIFO, H. pylori, parasites, or other microbial overgrowth, I recommend working with a functional medicine doctor to address your specific gut infections. Finally, some people may also benefit from a short-term low-FODMAP diet to address their gut problems, as outlined in this article (75).
