Free Histamine Intolerance Tools You Can Use Right Now

Reading about histamine intolerance only gets you so far. These nine tools handle the part that’s actually hard — tracking your own reactions, building a plan you can follow, and figuring out your personal thresholds instead of guessing from a generic food list. Everything below runs in your browser, saves your data locally, and is free to use.

Understand what’s happening to you

histamine intolerance quiz

Not sure if histamine is even your issue? Answer 15 questions about your symptoms and get a personalised score with suggested next steps in about 3 minutes.

histamine intolerance vs food allergy

Reactions that look like allergies but test negative for one? This tool compares your symptom pattern against both conditions and flags which one fits better.

histamine reaction timer

Log the moment you eat and the moment symptoms start. Reaction timing is one of the strongest clues for whether histamine is the driver — this makes it precise instead of a guess from memory.

Track your triggers

histamine food diary and trigger tracker

Log meals and symptoms, and let the built-in Insights view find the patterns you’d otherwise miss — which foods, combinations, and cycle phases actually precede a reaction.

histamine load calculator

Before a meal, add up what’s on the plate and see your cumulative histamine load in real time — because it’s rarely one food, it’s the combination that tips you over.

Build your plan

low histamine elimination diet plan

The full 4-week protocol broken into daily tasks with progress tracking, so you’re never wondering what to do next. Start here if you haven’t confirmed histamine intolerance yet.

low histamine meal builder

Build meals from foods that already score low on histamine content, so you’re not cross-checking every ingredient against a separate list.

Get your supplements right

histamine intolerance supplement stack builder

Answer a few questions about your symptoms and get a suggested starting stack, instead of piecing one together from six different articles.

dao supplement dose calculator

DAO dosing depends on your body weight and the histamine load of the meal — this works it out for you rather than leaving you guessing at a generic label dose.

New to all this? The most useful order is: take the histamine intolerance quiz first, then start the low histamine elimination diet plan, and log everything in the histamine food diary and trigger tracker as you go.
