How Histamine Intolerance Could Be Sabotaging Your Gut, Hormones, and Mood—And How to Fix It with a Functional Medicine Approach

Biohacking with Brittany

After tons of messages, I’m breaking down our detox journey—why we’re doing it, what we tested, and the shocking histamine link we discovered.

This goes beyond gut health—it's about how your genes, hormones, and mood are all connected. I break down histamine intolerance, key symptoms, and how you might be unknowingly sabotaging your health.

I TALK ABOUT:

06:40 – The functional medicine testing we did (Tiny Health code: BIOHACKINGBRITTANY, DUTCH Test, The DNA Company)

20:55 – Histamine-producing gut bacteria and symptoms of histamine intolerance

27:20 – Biomarkers to look for in your blood test (Siphox code: BIOHACKINGBRITTANY)

34:00 – What a low-histamine diet looks like (and what foods to avoid)
