DAO Enzyme

DAO Enzyme contains a purified form of diamine oxidase (DAO), the primary enzyme responsible for breaking down dietary histamine in the gut before it enters systemic circulation. By supporting histamine degradation at the intestinal barrier, DAO Enzyme helps to alleviate histamine reactions from dietary triggers.
