Hyman vs Cole vs Klinghardt — Three Models, One Missing Piece
The honest 2026 comparison of the three dominant integrative medicine models — and the structural gap none of them, at scale, closes. With a decision tree, the full cluster of supporting reads, and where to go next.
The three models
Each is right about something. Each is structurally blind to something. We named both, in plain English, before the deeper reads.
Level-1 Biochemistry at Scale
Mark Hyman
Fits if…
- — Mostly well, motivated
- — Wants data + early detection
- — Self-implementer
Breaks if…
- — Stalled chronic cases
- — Wants a real clinician relationship
- — Level 2+ problems
Intuitive Functional, Virtual-First
Will Cole
Fits if…
- — Symptomatic, not complex
- — Emotional layer feels central
- — Wants brand-led virtual care
Breaks if…
- — Complex Lyme / mold / metals
- — Wants hands-on ART or neural therapy
- — Heavy supplement load already
Five Levels of Healing, Complex Chronic
Dietrich Klinghardt
Fits if…
- — Chronic Lyme, mold, metals, autoimmunity
- — Stalled on functional protocols
- — Multi-system case
Breaks if…
- — First-pass optimization
- — Wants self-serve simplicity
- — Needs implementation infrastructure
Decision tree
Which model fits your case?
If you are…
Mostly well, want optimization & early detection
Hyman / Function Health works. Foundation gives you the same labs + a real clinician.
If you are…
Symptomatic, emotional layer feels central
Cole model is reasonable — read the honest review first. Or layer Foundation + nervous-system work.
If you are…
Plateaued on functional protocols (6+ months)
Level 2+ problem. A dashboard won't solve it. Foundation if budget-constrained, Concierge if not.
If you are…
Complex chronic — Lyme, mold, metals, autoimmunity, stalled
You need a Klinghardt-frame clinician. Private Concierge is built specifically for this case.
The one missing piece
Hyman, Cole, and Klinghardt all publish, prescribe, and protocol. None of them, at scale, walks the patient through week-by-week implementation with a real clinician on a real cadence.
It's not a content gap. It's not an evidence gap. It's an operating-model gap.
That's what we built. We guide; you implement; we review the data with you on a cadence. Same evidence base as functional medicine, different operating model.
