Function Health
Function Health is a preventive health platform founded in 2021 in San Francisco, built around one core idea: comprehensive lab testing at an accessible price. The platform offers 100+ biomarker tests — covering metabolic health, hormones, cardiovascular risk, thyroid function, vitamins, and more — for a flat annual membership fee of approximately $499/year. Results are reviewed with physician interpretation built into the platform, and prescriptions including GLP-1 medications are available for

Pros
- 100+ biomarker panel at ~$499/year is genuinely competitive
- Testing-first approach means GLP-1 prescriptions (and other treatments) are grounded in actual metabolic data, not just a questionnaire
- Physician interpretation built into results makes the data actionable for patients without a clinical background
- Strong credibility through association with physicians like Dr. Mark Hyman and the longevity/preventive medicine community
- Annual retesting creates a longitudinal health picture that most patients have never had access to before
- Platform is useful independent of any prescription
Cons
- Not designed for patients who simply want a fast path to a GLP-1 prescription
- The annual membership fee (~$499) is charged before any prescriptions are issued, which may not appeal to patients primarily motivated by medication access
- GLP-1 prescription availability is secondary to the testing mission and should be verified
- The platform skews toward patients who are health-data-oriented; patients who find extensive lab data overwhelming or anxiety-inducing may not enjoy the experience
- Geographic availability for prescription services may be more limited than for testing
