HistDAO^™ provides a concentrated source of diamine oxidase (DAO)—the main enzyme responsible for the degradation of ingested histamine. This formula delivers the clinically researched dose of DAO in an easy-to-swallow, gastro-resistant mini-tablet, which is essential for releasing DAO in the small intestine, where it breaks down food-derived histamine. HistDAO does not manage or address antibody-related or IgE-related food allergies.*

Suggested Usage

Adults: Take one tablet no more than 15 minutes before the consumption of histamine-rich foods, or take as directed by your healthcare practitioner.
