Functional medicine charges concierge prices for what insurance won't cover.
Functional medicine emerged from the integrative-medicine movement of the 1990s — Andrew Weil's Arizona Center for Integrative Medicine, Mark Hyman's work at Canyon Ranch and later the Cleveland Clinic Center for Functional Medicine, the Institute for Functional Medicine training programs. By the 2020s the category had become a consumer-facing concierge medicine industry, distinct from both insurance-based primary care and from supplement-only wellness.
The functional medicine boom of 2020–2025 produced billion-dollar valuations (Function Health), category-defining personalities (Mark Hyman, Casey Means, Dr. Mark Mancini, Dr. Will Cole), and a sustained category-rebuilding effort that restructured how consumers research, pay for, and consume health services.
Functional medicine charges concierge prices for what insurance won't cover. The category's growth depends on consumers willing to pay $500–$50K out of pocket for services traditional insurance doesn't cover.
The category structure
Tier 1 — National brands and platforms.
Function Health (Mark Hyman, Pranitha Patil, others). Comprehensive blood-testing service, ~$500/year. $1B+ valuation 2024. Hyman's existing brand anchored the launch.
Parsley Health (Robin Berzin, founded 2016). Integrative-primary-care subscription. Multiple market presence (NYC, LA, SF, Boston, online).
Wild Health (Mike Mallin, Matt Dawson). Genetics-and-bloodwork-based precision medicine. Concierge pricing.
Levels (Casey Means, Josh Clemente, others). Continuous glucose monitor-based metabolic health platform.
Inside Tracker. Blood-testing-based optimization platform.
Tier 2 — Concierge primary care with functional-medicine adjacencies.
Forward (closed late 2024 after raising $670M cumulative). The tech-forward concierge primary care platform that closed despite substantial funding.
One Medical (acquired by Amazon 2023). Primary care with wellness adjacencies.
Sollis Health. Concierge urgent care with wellness integration.
Tier 3 — Individual practitioners and small clinics.
The Mark Hyman / Cleveland Clinic Center for Functional Medicine model. Hospital-system-integrated functional medicine.
Independent functional-medicine clinics (~thousands across US). The IFM-certified-practitioner network.
Tier 4 — Adjacent longevity and biohacking.
Human Longevity Inc. Founded by Craig Venter. Comprehensive longevity testing.
Fountain Life. Tony Robbins co-founded longevity-focused medical platform.
Modern Age (closed 2023). Longevity-focused membership clinic.
What's driving the category
Insurance coverage gap. Insurance covers reactive treatment of disease, not proactive optimization of health. Functional medicine fills the gap consumers feel.
Distrust of traditional primary care. The 12-minute appointment, the lab-test minimum coverage, the medication-first treatment pattern create consumer demand for an alternative.
Personalization expectation. Consumers expect personalization in tech, retail, entertainment, food — and increasingly in health.
Founder credibility infrastructure. Mark Hyman's books and podcast, Casey Means' Stanford credentials and Surgeon General nomination, the various practitioner-founders' credibility infrastructure underpins category authority.
Continuous-monitoring technology. Continuous glucose monitors, wearables (Whoop, Oura, Eight Sleep), and blood-testing services create data infrastructure that the previous functional medicine generation didn't have.
Long-form content infrastructure. Hyman's The Doctor's Farmacy podcast, Means' Substack and book, the various practitioner podcasts and books built consumer-research infrastructure that fuels conversion.
What's holding it back
Out-of-pocket pricing. Most consumers cannot afford concierge functional medicine. The category remains structurally upper-middle-class and above.
Medical-establishment skepticism. The American Medical Association, the various medical specialty boards, and mainstream-medicine practitioners maintain sustained skepticism of functional medicine.
Regulatory complexity. Practitioners face state-medical-board scrutiny on supplement recommendations, off-label treatment protocols, and direct-to-consumer marketing claims.
Insurance coverage absence. Without insurance coverage, the category cannot reach mass market.
Clinical-evidence gaps. Many functional-medicine protocols have less peer-reviewed evidence than traditional medical interventions. The evidence gap is a sustained criticism.
The Forward collapse. Forward's late-2024 closure despite $670M cumulative funding illustrated category economics challenges. Concierge primary care at scale is operationally difficult.
What this means for the PR operation
The functional-medicine PR firm in 2026 runs:
Founder-credibility infrastructure (books, podcast guesting, speaking, Substack)
Peer-reviewed research publication where possible
Medical-establishment relationship management
State-by-state regulatory communications
Patient-success-story management
Insurance-coverage advocacy (where applicable)
Crisis comms for practitioner-credential challenges
Practitioner-network communications
The dedicated functional-medicine PR specialists are smaller boutiques. The major PR firms (Edelman, FleishmanHillard, Spectrum Science) all have health practices that increasingly include functional-medicine adjacent clients.
The campaigns that proved it
Mark Hyman's sustained content output. Hyman's The Doctor's Farmacy podcast (~500 episodes), ten bestselling books, Function Health co-founding, Cleveland Clinic Center for Functional Medicine work, and continuous press visibility built category-default authority.
Casey Means' Surgeon General nomination cycle. Means' 2024 Trump-administration nomination as Surgeon General positioned Levels — and functional-metabolic-health more broadly — at the center of US health policy conversation.
Function Health's launch and scaling. The blood-testing service paired Hyman's credibility with comprehensive testing and tech-platform delivery. $1B+ valuation in under two years.
Wild Health's genetics-based positioning. The Mike Mallin and Matt Dawson-founded platform built sustained credibility through genetics-and-biomarker integration.
Parsley Health's hybrid insurance-and-cash positioning. Robin Berzin's platform navigated the insurance-coverage gap by accepting some insurance while maintaining premium-membership cash-pay positioning.
The structural takeaway
Functional medicine became a billion-dollar consumer category by selling to upper-middle-class and affluent consumers what insurance doesn't cover. The category's growth depends on continued willingness to pay out of pocket — and on sustained founder-credibility infrastructure that distinguishes functional medicine from supplement-only wellness.
The brands that scaled (Function Health, Parsley, Levels) did so on founder-credibility-and-technology integration. The brands that struggled (Forward, Modern Age) did so on category-economics challenges.
Functional medicine charges concierge prices for what insurance won't cover. The PR operations that work the category navigate the gap.
