If histamine responses feel chaotic or not easy to manage regularly….
Histamine might be the reason—not the cause.😅
But why?
Your body processes histamine using two enzymes:
🔹 DAO – works in your gut (extracellular)
🔹 HNMT – works in your brain and cells (intracellular)
When these enzymes are underperforming—or “dirty”—histamine builds up. That’s when symptoms show up.
🧹But what dirties them?
• Gut inflammation or infections (SIBO, candida, mold)
• Nutrient deficiencies (think B2, B6, copper, methyl donors)
• Methylation dysfunction (especially MTHFR and low folate/B12)
• Estrogen excess or impaired detox pathways
• Environmental triggers like fragrances, EMFs, and mold
💢 Methylation Matters
HNMT needs methyl groups to support the breakdown of histamine.
Sluggish methylation? Histamine builds—no matter how clean your diet or how much DAO you take.
Clean MTHFR = normal methylation = healthy histamine.
🦠 Gut Comes First
DAO is made in your gut lining.
If your gut’s inflamed, DAO can drop—and histamine can rises.
Quercetin and DAO enzymes = symptom support*
But without gut repair, it’s a band-aid.🩹
Your takeaway 🫵
If histamine responses feel chaotic or not easy to manage regularly….
Start upstream.
Support flows downstream.
Order matters
