Hist Diamine is a patented enzyme formula containing diamine oxidase (DAO)—the main enzyme responsible for the degradation of ingested histamine. This enzyme has been clinically tested and found to break down food-derived histamine in the digestive tract.
DAO is not absorbed and does not have systemic
activity. Hist Diamine does not manage or address antibody-related or IgE-related food allergies.*
