Diamine oxidase (DAO) is your body’s first-line defense against histamine ingested through the diet or released within the gut.

Main highlights

Relief In One Capsule: While other histamine blocking or DAO supplements may require you to take multiple capsules, our Bravado Labs formulation provides the antihistamine power you need with just one capsule.

Reduce Histamine On The Go: With this small, 60-capsule bottle of our DAO supplement, you can add DAO whenever the occasion calls for it. Just take one capsule hours prior to consuming histamine-rich or DAO-blocking food or drink.

Eat Histamine Rich-food: If wine and cheese parties end with you sniffling, sneezing, or worse, Bravado Labs histamine block can help by increasing your levels of DAO, which in turn helps your body to break down histamines commonly found at high levels in alcohol, cheese, certain vegetables, shellfish, smoked meats, and other fermented foods.
