Free on-demand class for clinicians
Know exactly which patients food dyes are actually hurting.
And spare everyone else the elimination diet. A short, evidence-graded clinical class — the four phenotypes, the supervised workup, and what the data really show — so you can answer the questions your patients are already asking about the 2025–2027 dye phase-out.
Why now
Your patients are about to ask. Be the clinician with a real answer.
Regulators are removing certified petroleum food dyes from the U.S. supply between 2025 and 2027. Headlines are outpacing evidence, and families are arriving with strong opinions and simple questions. Most reactions are not what patients assume — and a blanket "avoid all dyes" helps almost no one.
The clinical problem
One question, four different diseases.
What patients bring you
"Dyes make my kid worse." It sounds like one thing. Clinically it's at least four — true IgE allergy (rare but never-miss), a small-but-real behavioral effect, a GI/barrier signal, and a nonspecific metabolic overlap that's easy to over-attribute. They don't share a workup.
What this class gives you
A disciplined method: recognize the phenotype, confirm with a supervised elimination-and-challenge, order the labs that actually help, and personalize with genetics — without over-claiming. Help the patients who truly react, and spare everyone else the restriction.
What you'll learn
A primer and six modules you can run on Monday.
Roughly a lunch hour, chaptered so you can watch a module at a time. Every clinical claim carries an explicit A–D evidence grade.
Primer — the Signalome lens & IHC
See dye reactions as signaling, not folklore. Optional but recommended.
Recognition
The four phenotypes and how to tell them apart at the bedside.
Diagnosis & testing
The supervised elimination-and-challenge workup, plus which labs actually help.
Genetic & PGx testing
Where genetics personalize the plan (NAT2, GST, others) — and where they don't diagnose.
Treatment
Acute management, avoidance done right, and evidence-graded adjuncts with mechanisms.
Optimization
Protect–Optimize–Regenerate: barrier, microbiome, and the 12-week re-check.
Integration
A Monday-morning workflow you can actually run, with referral thresholds.
Who it's for
Built for the clinicians fielding these questions.
Primary care & pediatrics
The front line for these questions.
Allergy, GI & integrative
Deeper phenotyping and workup.
NPs, PAs & RDs
Anyone counseling families on elimination.
Clinician-entrepreneurs
Building an evidence-based cash-pay service line.
What it is — and what it isn't.
This is not an anti-industry crusade or a promise that removing dyes fixes everything. It's a disciplined clinical method: identify the patients truly affected, help that subset meaningfully — especially the allergic and the true responders — and protect everyone else from an unnecessary restrictive diet. Genetics and labs personalize the plan; a supervised challenge is what confirms it.

A clinical, evidence-graded walk through the full pipeline — recognition, diagnosis, testing, treatment, and longitudinal optimization — designed for real decisions in a real visit, not headlines.
Questions
What clinicians ask before they start.
Is it really free?
Yes — the full class is free on demand. Optional paid resources are introduced afterward, but the class stands on its own.
Do I earn CME?
Designed to be CME-eligible; accreditation is in progress. We'll note current status on the class page — we won't claim credit that isn't yet certified.
Does this mean every patient goes on an elimination diet?
The opposite. Blanket avoidance helps almost no one; the class teaches you to find the patients who truly react and spare the rest.
How long is it?
Roughly a lunch hour — about 55 minutes of core modules plus a 12-minute optional primer — chaptered so you can watch a module at a time.
Which labs does it recommend?
No lab diagnoses dye sensitivity; a supervised elimination-and-challenge is the reference standard. Focused, validated markers can support the workup — barrier markers LBP and soluble CD14, inflammatory tone (hs-CRP, fecal calprotectin), and specific IgE when true allergy is on the table. Non-validated tests such as IgG/IgG4 food panels, ALCAT, and hair analysis are discouraged.
