Living with histamine intolerance is exhausting
You restrict your diet, avoid your favourite foods, and still react. And no one seems to have the answers.
You avoid everything and still react
You've cut out wine, tomatoes, and aged cheese — but reactions keep happening. The rules don't seem to apply to you.
Every doctor gives you a different answer
Some dismiss it entirely. Others give you a food list that contradicts the last one. You're left to figure it out yourself.
You've been managing symptoms, not solving them
Antihistamines help short-term. But you want to know your actual triggers so you can live without constant fear.
There is a better way.
Hista AI changes that.
The process
Three steps to knowing your triggers
Simple daily actions. Powerful AI doing the heavy lifting.

AI builds your personal trigger map
Pattern detection across hundreds of data points — finding connections no human could see manually.
Know your risk before it happens
Wake up to a 3-day forecast personalised to your sleep, stress, hormones and diet.

The breakthrough feature

People who stopped guessing
From users who had been suffering for years before finding Hista AI.
“After 3 years of unexplained migraines I finally know it's red wine and aged cheese. The Trigger Fingerprint found it in 6 weeks of logging.”

The science
Built on clinical methodology, not guesswork
RPAH Elimination Protocol
Our 28-day protocol is based on the methodology developed by Royal Prince Alfred Hospital — the most clinically validated approach to identifying food intolerances.
DAO Enzyme Science
Hista AI is built around the science of diamine oxidase. We track every factor that affects DAO activity — sleep, stress, hormones, and more.
Peer-Reviewed Criteria
Our diagnostic thresholds and food ratings are derived from peer-reviewed research — not crowd-sourced opinion or generic food lists.
