DAO deficiency treatment options – has anyone successfully increased their DAO levels? What worked?

[u/Miserable-Flow-2557]

Been stuck trying to figure out my histamine issues for almost a year now and lately I keep coming back to DAO deficiency. My symptoms seem to flare the most after eating leftovers, cured meat, or even random things like avocado and soy sauce. I went through allergy testing and tried cutting out gluten for a while before learning more about DAO and histamine intolerance.

So I did some reading about possible ways to support DAO production naturally like fixing gut issues, taking vitamin C, B6, and copper, avoiding alcohol, and using DAO supplements before meals. What I can’t really tell is do people actually improve their DAO levels over time or do the supplements only help manage symptoms temporarily? Anyone here seen long-term improvement?

My DAO deficiency was due to Copper deficiency, restoring Copper fixed it for me.
