DAO Mini contains the enzyme diamine oxidase (DAO), provided in small, easy-to-swallow tablets designed for use before eating meals that contain histamine-rich foods. Each tablet supplies 30,000 HDU of DAO. DAO is naturally present in the body and is also found in certain animal protein sources.
Histamine is a naturally occurring substance found in everyday foods such as fermented vegetables, aged cheese, cured meats, and red wine. DAO Mini offers a practical way to manage your intake of histamine through diet, particularly when eating out or consuming products that may contain higher levels. It is free from gluten and soy, and created with minimal, carefully selected ingredients.
Intoleran was founded in 2008 by Remko Hiemstra, who set out to make eating enjoyable again after navigating his own lactose intolerance. With a strong scientific focus, Remko and his team developed targeted digestive supplements that support the breakdown of specific food components, including lactose, fructose, and histamine. Every formula uses only essential ingredients, avoiding unnecessary additives and keeping digestion support clean and simple. Guided by expertise and a practical, caring approach, Intoleran creates products that help you enjoy food with comfort and confidence, so you can eat freely and live well every day.

Fillers: Microcrystalline cellulose, hydroxypropyl cellulose; Porcine kidney protein extract with 7% Diamine Oxidase (DAO); Gelling agent: ethyl cellulose; potato starch; Stabilizers: sodium alginate, magnesium stearate; Medium chain fatty acids; Gelling agent: hydroxypropyl methyl cellulose; Stabilizers: oleic acid, stearic acid.

Recommended Dosage: Take 1 tablet at a time.
Maximum Daily Dose: Do not exceed 3 tablets per day.
Age: These tablets are suitable for individuals starting from 4 years of age.
Advice: When using DAO, it is important to first lower the histamine level. We recommend following a low-histamine diet (preferably under the supervision of a dietitian), in combination with taking DAO three times a day (at breakfast, lunch, and dinner). After 2 to 4 weeks, histamine levels should be reduced. After that, you can slowly start reintroducing histamine into your diet and/or reducing the DAO supplement, depending on your personal situation.
In addition to diet, factors such as stress, certain medications, alcohol, hormonal fluctuations, and sleep can also promote the release of histamine.
