The Active Ingredient Is: Diamine Oxidase (DAO) Enzyme

Diamine oxidase is basically an enzyme that helps break down histamine in the body.

This blend pairs DAO with essential cofactors and antioxidants, including vitamins and minerals that support histamine metabolism and the handling of byproducts like ammonia and acetaldehyde.

What Does Diamine Oxidase Do?

DAO helps with histamine metabolism by speeding its breakdown, which can help keep normal body responses to histamine-containing foods. Cofactors like B vitamins, vitamin C, magnesium, zinc and related nutrients support the enzyme’s activity and the processing of related metabolic byproducts.

This product highlights the form and nutrient context to support histamine metabolism through several complementary cofactors.
