Histamine intolerance is not always a “bad genes” problem.
Yes, genes like DAO, HNMT, MTHFR, COMT, and MAOA can influence how your body breaks down histamine, methylates, clears neurotransmitters, and processes inflammation.
But I see this all the time…
Someone gets genetic testing and thinks, “This is why I’m reactive", and taking 20 different supplements to support my genes will fix it 🫠
And while genetics can absolutely explain part of the pattern, they usually do not explain why symptoms suddenly got worse.
They do not explain why you tolerated foods for years and now you can’t.
They do not explain why your flares line up with mold exposure, hormone shifts, stress, constipation, poor sleep, infections, SIBO, or toxin overload.
Genes can influence how your body handles histamine, but they usually aren’t the reason your symptoms started or got worse.
That means we have to look at things like:
Gut dysbiosis
Poor bile flow
Inflamed gut lining
Hormone imbalance
Mold and toxin burden
Nervous system dysregulation
Sluggish detox pathways
Constipation
Blood sugar instability
Nutrient depletion
Because histamine intolerance is usually not about one gene.
It is usually a sign that the body’s histamine bucket is overflowing.
And when you understand what is filling that bucket, you can finally stop chasing random supplements and start building a plan that actually makes sense.
