we read it for you

Naturdao is the only product on the market with vegetable Diamino Oxidase. Naturdao's Catalase Enzyme comes from the membranes of legumes.


Histamine is a necessary substance that our body produces in the form of defense after an injury, sting or during allergic reactions. It is also essential to produce and secrete gastric acid that helps us digest food and also works as a neurotransmitter or as a messenger in the brain. Therefore, it is a mistake to think that when we talk about histamine, we are talking about a substance that is harmful to the body, quite the contrary, without histamine we could not carry out basic functions for survival.

Naturdao only uses ingredients of plant origin (including the capsules). Therefore it is totally SUITABLE for vegans and Vegetarians.

When can histamine become a problem?

When we accumulate an excess of histamine that we are not able to eliminate later. In these cases, we speak of histamine intolerance, when our body collapses due to an excess of histamine in the body and this excess manifests itself with different symptoms such as: migraines, joint pain, allergies, itching, hives, rhinitis, insomnia, diarrhea or pasty stools, low blood pressure, anxiety or dizziness, among others.

When or why can we not eliminate excess histamine?

The most common reason is when we have a DAO (Diamino Oxidase) deficiency, which is responsible for breaking down histamine in the intestines. But not only the DAO enzyme is necessary for its elimination, but also another enzyme called HNMT (histamine N-methyltransferase), which also helps us to eliminate histamine. Another reason, although less frequent, could be some type of genetic defect that prevents these detoxification pathways from acting, but normally what we find most in consultation are people with one of these two enzymes, or both, blocked or in low amounts and for this reason, a diet high in histamine could be enough to trigger the symptoms.

How would I know if I suffer from DAO deficiency?

The low histamine diet is a great tool for treating histamine intolerance. Following a strict diet low in histamine and other biogenic amines for 2-4 weeks may be enough to check if we suffer from histamine intolerance or not. In the event that the symptoms subside when dieting, we can say that there is histamine intolerance and take the next step, which is to find and analyze the reason for said intolerance to fix the root problem. There are people who, just by eliminating red wine, chocolate, cheeses and sausages, already notice improvement; Do you have symptoms with any of these foods? If the answer is yes, you are interested in knowing how to correctly follow a DAO deficiency diet.


Eliminate foods high in histamine and other biogenic amines for 4 weeks strictly.

The ideal would be to keep a diary of symptoms to see how they change or reduce while on the strict diet and likewise check if by gradually introducing foods with a high histamine content, the symptoms remain controlled or if they manifest again. This will allow you to measure your degree of tolerance to certain "trigger foods" and this information will help us guide changes in the diet in the medium and long term.

Consume fresh animal protein, that is, do not buy frozen or cured meats.

Consume meat, fish and seafood with a short freezing time, that is, you can buy fresh on the weekend, freeze if necessary and consume these foods in the next 5 days so that conservation is short and does not excessively increase the amine content.

Studies indicate that cooking food reduces its histamine concentration, for example, boiling spinach and discarding the water may be good advice.

Do not buy frozen vegetables such as those used in salads, soups, peas and others, nor canned, fermented or in brine. Eat fresh and freshly made vegetables.

Do not carry out the diet indefinitely and neither without the supervision of a qualified nutritionist, since the exclusion of several foods that this diet contemplates can cause significant nutritional deficits, as well as loss of bacterial diversity.
