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.*

Supports Healthy Degradation of Food-Derived Histamine*
Enhances the Presence of Diamine Oxidase in the Digestive Tract*

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

Povidone iodine is fantastic and this diluted nasal spray is fast acting and a great preventive measure! I never travel on airplanes without using it!
