DAO Vital
Dietary supplement with the enzyme diamine oxidase (DAO) and vitamins C and B6.
How DAO Vital works
Histamine is normally broken down in the body by the enzyme diaminooxidase (DAO), especially in the intestines. When DAO activity is reduced or its production is insufficient, histamine accumulates and can cause histamine intolerance. After taking DAO Vital, the enzyme is released in the digestive tract, where it breaks down food histamine before it is absorbed into the blood.

What role does the DAO enzyme play? +
Why are vitamins C and B6 important? +
The symptoms of histamine intolerance are alleviated by the DAO enzyme, which is found in various dietary supplements. For some patients, taking it 15–30 minutes before meals helps, together with an adequate intake of vitamins C and B6. A symptom diary also helps a great deal — it records what was eaten and how one feels; after a few weeks, it is possible to infer which foods are causing problems.

Frequently asked questions
When and how should I take DAO Vital to make it most effective?+
DAO Vital is recommended to be taken 1–2 capsules 15–30 minutes before a meal containing histamine, especially if you suffer from histamine intolerance. They should be taken with enough water so that the acid-resistant capsule dissolves properly in the intestines and the enzyme is released in the digestive tract.
Do I need to take DAO Vital with every meal?+
No. DAO Vital is best taken only before meals that contain histamine or promote its release (for example fermented, aged, or processed foods). These meals can trigger symptoms of histamine intolerance in more sensitive people. If you notice symptoms, it is advisable to adjust your diet and supplement it with the DAO enzyme — especially if the problems are recurring and caused by histamine intolerance.
Can I combine DAO Vital with other supplements or medications?+
In most cases, yes, but if you are taking antihistamines, antibiotics, or medications affecting the intestines, it is advisable to consult a doctor or pharmacist to avoid unwanted interactions.
Is DAO Vital safe for vegans, celiacs or diabetics?+
Yes, the product is suitable for vegans, celiacs, and diabetics. It contains no animal-derived ingredients, gluten, or sugar.
Is this product suitable for long-term use?+
Yes, DAO Vital is also suitable for long-term use, especially if a person has chronic histamine intolerance, often consumes foods with a higher histamine content, or regularly experiences symptoms of histamine intolerance.
How do I know if I have histamine intolerance?+
The symptoms of histamine intolerance vary and can resemble an allergy — digestive problems (abdominal pain, bloating, diarrhea, nausea), skin reactions (hives, redness, eczema), runny nose and itchy eyes, as well as migraines, fatigue, dizziness, or heart palpitations. Keeping a symptom diary helps — record what you ate and how you felt. A doctor can assess a definitive diagnosis (for example, an allergist or immunologist).
Which foods are high in histamine?+
Foods with a high histamine content, or those that promote its release, include fermented foods (sauerkraut, kimchi, soy sauce), aged cheeses (parmesan, camembert), smoked meats and processed meat, alcohol (wine, beer, champagne), fish and seafood (especially smoked and canned), chocolate and cocoa, nuts, tomatoes, spinach, and eggplant.
How quickly does DAO Vital work?+
DAO Vital acts locally in the digestive tract during the digestion of a meal — the enzyme begins to break down histamine from food shortly after ingestion. Its effect is tied to a specific meal, which is why the capsule is taken 15–30 minutes before a meal containing histamine. Perception of symptom relief is individual.
Does DAO Vital have side effects?+
DAO Vital supplements an enzyme that occurs naturally in the body and is generally well tolerated when the recommended dosage is followed. Do not exceed the recommended daily dose. If you have health problems, are pregnant, or are breastfeeding, consult your doctor before use.
Will DAO Vital cure histamine intolerance?+
DAO Vital is not a medication and does not cure histamine intolerance — it helps break down histamine ingested with food and makes it easier to manage situations when you cannot avoid food containing histamine. In histamine intolerance, diet modification (a low-histamine diet) and symptom tracking remain important, ideally in collaboration with a doctor.
