DAO (Diamine Oxidase)
An enzyme that helps to break down histamine from food, relieving symptoms of histamine intolerance.
Also known as: Histaminase
Overview
Diamine Oxidase (DAO) is an enzyme that is naturally produced in the body and is responsible for breaking down histamine from the foods we eat. A deficiency in DAO can lead to histamine intolerance, a condition that can cause a variety of symptoms. DAO supplements can help to support the breakdown of dietary histamine.
