Aperitif - Diamine Oxidase Enzyme - 30 Capsules | Tolerance

Aperitif's delayed-release capsule resists stomach acid and releases the enzyme at the correct pH in the intestinal tract, where it acts locally on food-derived histamine.Take one capsule 15–20 minutes before high-histamine food or drink, swallowed whole. Maximum three capsules daily. Suitable for occasional use before any high histamine meals or as ongoing mealtime support during elimination and reintroduction protocols. Not suitable for vegetarians (DAO is porcine-derived).Tolerance is a UK-based brand dedicated exclusively to histamine intolerance, from genetic testing to food supplement solutions, working alongside leading histamine nutrition experts.
