Histamine Tracker
Vanilla extract
Vanilla extract is alcohol-based, and alcohol is a known DAO blocker — the main consideration here.
Pure vanilla extract is made by steeping vanilla beans in alcohol, which is what gives it that concentrated flavor.
-
The alcohol factor — alcohol is a well-established DAO blocker, meaning it can make it harder for your body to break down histamine from other foods; even small amounts may matter for sensitive individuals
-
Alternatives exist — vanilla powder, vanilla bean paste, or non-alcohol vanilla flavor may be better tolerated if the alcohol component is a concern
Small amounts used in baking are often fine for most people, but if you're particularly sensitive, vanilla powder is an easy swap.
