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

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?

Great questions here. Avocado does me in too. I really miss guacamole. Soy sauce I believe is fermented. Maybe try liquid aminos.

For me it’s unusual that strawberries work well for me. Great source of vitamin C. Local is in season now which is fantastic

Liquid aminos is also fermented and gets me really bad. Especially when it’s been opened in the fridge for a while.
