Histamine intolerance (HIT) is assumed to be due to a deficiency of the gastrointestinal (GI) enzyme diamine oxidase (DAO) and, therefore, the food component histamine not being degraded and/or absorbed properly within the GI tract.
How do I know if I have DAO deficiency?
The most frequent symptoms derived from DAO deficiency are: Migraine, headache and tinnitus. Gastrointestinal disorders, especially those associated with Irritable Bowel Syndrome (IBS), such as constipation, diarrhea, satiety, flatulence or bloating. Dermatological disorders such as dry skin, atopy and dermatitis.
Does low b12 cause histamine intolerance?
Cofactors. When the body is low in B-vitamins, vitamin C and copper, histamine may not break down sufficiently to overcome symptoms of intolerance. Copper and vitamin C are crucial components of the DAO enzyme and B6 is a key cofactor that enables DAO to degrade histamine.
Why did I suddenly develop histamine intolerance?
Bacterial overgrowth is another contributing factor for developing a histamine intolerance. Bacteria grows when food isn’t digested properly, causing histamine overproduction. Normal levels of DAO enzymes can’t break down the increased levels of histamine in your body, causing a reaction.
What vitamin reduces histamine?
Vitamin C acts as a natural antihistamine by reducing the amount of histamine your body produces in response to an allergen. It might help reduce mild symptoms like sneezing, runny nose, congestion, and watery eyes due to allergic rhinitis.

Can B12 raise histamine levels?
A vitamin B12 injection also releases (a lot of) histamine from the mast cells. When there is a lot of free histamine in our body, there is an elevated histamine level.
Does zinc increase histamine?
Thus physiological concentrations of zinc inhibit the release of histamine from human basophils and lung mast cells, presumably by blocking Ca2+ uptake induced by anti-IgE activation.
Does magnesium help lower histamine levels?
Magnesium is key mineral that can help with histamine intolerance and mast cell activation and most people find that upping their magnesium intake can help with oral and gastric tolerance and reduce symptoms.
Can you reverse histamine intolerance?
Aside from dietary changes, there is no set treatment for people with histamine intolerance. However, one or more of the following approaches may help: taking antihistamines. taking DAO enzyme supplements.
How do I heal my histamine intolerance?

What supplements help with histamine intolerance?
7 Best Supplements for Histamine Intolerance

- Vitamin C.
- Quercetin.
- Bromelain.
- Stinging nettles.
- N-acetyl cysteine.
- Natural D-Hist.
What is the strongest natural antihistamine?
Nettles. Nettle leaf is a natural antihistamine that naturally blocks histamine production. It can be made in to a tincture or tea, but for allergy relief, capsules made from dried nettle leaves are the most effective option.
What fruit is a natural antihistamine?
Citrus Fruits – Vitamin C (ascorbic acid) is an antioxidant that prevents oxidative stress in the body and is also a natural antihistamine. Consuming adequate amounts of Vitamin C from citrus fruits such grapefruits, oranges, lemons and kiwis can also help fight infections.
What is the fastest way to reduce histamine?
Vitamin C is a natural antihistamine, which means it can lower histamine levels and mitigate allergic reactions and symptoms. Consume plenty of Vitamin C rich foods, like tropical fruits, citrus fruits, broccoli and cauliflower, and berries.
What food blocks DAO?
These foods do not necessarily contain histamine but they block the action of DAO and therefore they potentiate the effects of elevated histamines.
- Alcohol.
- Bananas.

- Cow’s Milk.

What causes low DAO levels?
Nutrient deficiencies – A B6, vitamin C, zinc or copper deficiency, may put you at risk or contribute to a DAO deficiency. Consuming histamine-rich food – Some foods may inhibit the functioning of the DAO enzyme, or contribute to symptoms by overloading the body with more histamine than your enzymes can break down.
What enzyme breaks down histamine?
The enzyme diamine oxidase (DAO) is considered for the gastrointestinal degradation of histamine.
Why are my histamine levels high?
If you have a food allergy, histamines are in on that response process, too. When you accidentally eat or drink something you shouldn’t, they’ll work in your gut to trigger your allergic reaction. Some foods are also naturally high in histamines. These include aged and fermented foods and alcohol (especially red wine).
