- Support Digestion of Food‑Derived Histamines – Lower DAO activity may result in higher levels of histamine being absorbed through the small intestine and accumulating in the blood. HistaGest-DAO provides supplemental diamine oxidase enzyme. Unlike common digestive enzyme products, this enzyme is responsible for breaking down food-derived histamine to help support normal and healthy histamine metabolism.*
- Convenient ‘Take-Anywhere’ Dispenser – This DAO supplement offers small tablet delivery in a convenient travel dispenser for portability and ease of use when on‑the‑go. Each tablet provides 20,000 histamine-degrading units (HDU) of diamine oxidase (DAO) from porcine kidney extract to promote the degradation of dietary histamines.*
- Just Take One Before Histamine-Rich Foods – Taking one diamine oxidase DAO supplement tablet before each meal promotes the amount of DAO in the small bowel to help break down histamine in the digestive tract, support digestive health and soothe digestive discomfort associated with sensitivity to histamine-rich foods.*
- Delayed-Release Tablets Designed for High Performance – DAO supplements can be less effective if they do not reach the small intestine. HistaGest-DAO diamine oxidase supplement is made with gastro-resistant, coated tablets with delayed-release technology that allows the DAO enzyme to reach the small intestine where it performs its action.*
- Clinically-Trusted Care – DFH is the #1 practitioner supplement brand recommended by functional medicine professionals and the #1 practitioner supplement brand personally trusted by functional medicine professionals.**
