XYMOGEN HistDAO — DAO Enzyme Supplement, 20,000 HDU/Tablet, Digestive Health Support (60 Tablets)

What is HistDAO?

XYMOGEN HistDAO is a targeted diamine oxidase (DAO) enzyme supplement designed to support digestive processes by aiding the breakdown of food-derived histamine. Each tablet delivers 20,000 HDU of DAO, a potency chosen to provide a full serving in a single pill and simplify daily use.

In a thoughtful reformulation, the serving size moved from two capsules to one tablet, delivering the same enzyme strength in a compact, easy-to-take format. This design aims to fit seamlessly into daily routines without sacrificing potency.

HistDAO acts locally in the digestive tract, with the enzyme working in the gut rather than circulating through the bloodstream. The product has been clinically tested to assess its ability to break down histamine from meals within the gut. Individual experiences may vary, and results can depend on diet and routine.

Why this might fit your routine

This single tablet brings together digestive health, immune considerations, and gastrointestinal wellness in one formula. The formulation emphasizes a practical, everyday approach to enzyme nutrition and a focus on gut-specific action rather than systemic activity.
