Xymogen HistDAO Details
Xymogen HistDAO, 60 Delayed Release Tablets provides a clinically tested enzyme formula containing diamine oxidase (DAO), the primary enzyme responsible for breaking down histamine from foods. By supporting the healthy degradation of food-derived histamine, Xymogen HistDAO may help reduce digestive discomfort, bloating, or other symptoms associated with histamine intolerance.
This delayed-release formula ensures DAO survives stomach acid and reaches the digestive tract, enhancing enzyme activity where it’s needed most. Xymogen HistDAO supports balanced histamine digestion but is not intended to manage IgE-related food allergies or antibody-mediated responses.
Ideal for:
- Individuals experiencing histamine intolerance
- Supporting healthy digestion of histamine-rich foods
- Reducing occasional bloating, discomfort, or digestive upset linked to histamine
- People seeking enzyme support for overall digestive health
