Seeking Health DAO Enzyme Diamine oxidase (DAO) is the enzyme your body uses to break down histamine from food in the digestive tract. When DAO activity is low, histamine from aged cheeses, fermented foods, wine, leftovers, and cured meats can accumulate rather than clear — showing up as bloating, headaches, skin reactions, nasal congestion, or general digestive discomfort after meals. This formula delivers DAOgest, a patented porcine kidney-derived DAO enzyme, at 30,000 HDU per capsule. It works directly in the gut to support histamine breakdown before it can be absorbed, making it a practical tool for anyone navigating histamine intolerance or reacting to high-histamine foods. Take one capsule before eating or drinking anything high in histamine. It is also used by some practitioners to support histamine levels outside of meals — including during pregnancy or for menstrual comfort, as histamine and estrogen have a reciprocal relationship. Contains porcine-derived ingredients. Not appropriate for those with pork restrictions.
