- Supports Healthy Degradation of Food-Derived Histamine*
- Enhances the Presence of Diamine Oxidase in the Digestive Tract*
HistoDAO™ is a patented enzyme formula containing diamine oxidase (DAO)—the main enzyme responsible for the degradation of ingested histamine. This enzyme has been clinically tested and found to break down food-derived histamine in the digestive tract. DAO is not absorbed and does not have systemic activity. HistDAO does not manage or address antibody-related or IgE-related food allergies.
If you’re unsure whether histamine intolerance or low DAO activity may be contributing to your symptoms, we offer histamine and DAO testing to help determine the root cause and provide personalized support.
Recommended dosage Adults: 2 tablets 1 time per day. Take 15 minutes before a meal. Do not chew or break tablets. Swallow whole.
