Description:
HistoDAO™ 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. HistDAO does not manage or address antibody-related or IgE-related food allergies.

Suggested Use:
Take one to two capsules no more than 15 minutes before the consumption of histamine-rich foods, or take as directed by your healthcare practitioner.
