The Diamine Oxidase (DAO) contained in DAOkids serves as a supplement to the enzyme found in the body, which is in charge of metabolizing histamine. Taking one tablet of DAOkids before each meal increases the amount of DAO in the small bowel and therefore also boosts histamine degradation. This accelerates in the digestive tract the processing of the histamine found in different foods, that triggers the symptoms.
The DAO enzyme contained in DAOkids acts only in the intestine, it is not absorbed and has no systemic activity, hence it is considered a harmless product with no adverse effects.
