BUILT BY SOMEONE WHO LIVES WITH HISTAMINE INTOLERANCE After years of struggling with histamine intolerance, insomnia, and chronic pain, I worked with nutritionists, therapists, and sleep specialists to understand how food, sleep, stress, and daily habits affect my symptoms. What I kept wishing for was a simple way to track everything together. So I built it. I use Histamine Tracker every day, and I hope it helps you too.
