Formulation
Formulation re: Other
Supports healthy degradation of food-derived histamine
Formula re: Contains
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.
Formulation re: Does NOT Contain
Formulated to exclude: Wheat, gluten, corn, yeast, soy, dairy products, fish, shellfish, peanuts, tree nuts, egg, sesame, ingredients derived from genetically modified organisms (GMOs), artificial colors, and artificial sweeteners.
