Mito Health
The Function Health alternative built around past-lab upload and biological age: 100+ biomarkers, AI insights, and a 1:1 MD consult from $349/yr (Core).
A comprehensive-diagnostics membership that imports your past bloodwork from day one: 100+ biomarkers, biological age, AI action plans, and a 1:1 MD consult from $349/yr Core, with Pro and Ultra tiers that layer in advanced and cancer screening.
Mito Health entered the comprehensive-diagnostics market in 2023 with a clear hook: import the bloodwork you already have so the insights work on day one. Core is $349/year (1 annual draw, 100+ biomarkers, AI insights, a biological-age readout, and a 1:1 MD consult), and the platform tiers up from there - Pro at $699 adds 5 advanced tests (heavy metals, omega-3/6, cholesterol particle, IGF-1, cystatin-C), and Ultra at $1,899 adds a multi-cancer early-detection test and a gut-health test. Genetics and gut-microbiome work are available as add-ons.
The honest comparison is Function Health, and on price it is basically a wash: Mito Core is $349 against Function's $365, so this is a features decision, not a price one. Mito's edge is past-lab upload (Function only tracks data drawn through its own service, so your first Function year is partly educational), the biological-age readout, and the tiered structure plus genetics and microbiome add-ons. Function counters with a wider 160+ marker panel, two included draws a year vs Mito Core's single draw, and a longer operating track record. Pick based on which of those matters to you.
For longevity buyers, the right play in 2026 is to pick one comprehensive diagnostic platform (Function or Mito) and not run both. Pair it with a single-vertical service like Marek Health for hormone optimization if you need active prescription work.
Buyers who want comprehensive biomarker tracking plus a biological-age readout and have past bloodwork to upload so insights start on day one, or who want a tier path up to advanced and cancer screening.
You want the widest single panel and two included draws a year (Function goes broader), you're already committed to Function's ecosystem, or you need active hormone-optimization prescriptions (use Marek Health alongside).
Pros
- Past-lab integration - upload historical bloodwork and AI insights work from day one (Function does not allow this)
- Biological-age readout surfaced alongside the panel - a longevity-native metric Function does not headline
- Tiered structure (Core $349 / Pro $699 / Ultra $1,899) lets you layer in advanced tests and multi-cancer + gut-health screening as needed
- Genetics and gut microbiome add-ons available - Function does not currently cover these
- 100+ biomarker panel - broader than InsideTracker (48), Lifeforce (~50), and most direct-to-consumer alternatives
- 1:1 MD consult included - real MD review, not algorithm-only output
- AI-driven personalized action plans - recommendations tied to individual results vs reference-range generic advice
- Near-identical price to Function ($349 Core vs $365) makes this a features decision rather than a budget tradeoff
Cons
- Core includes a single annual draw - Function includes two draws a year at a near-identical price
- Narrower panel than Function (100+ vs 160+) on the comparable tier
- Younger brand (2023) - Function Health has a longer operational track record
- Smaller installed base - community size, peer-comparison data, and editorial coverage trail Function meaningfully
- Less mainstream brand recognition - buyers unfamiliar with Mito may need education
- Affiliate program reliability less battle-tested than older networks
- No native ecosystem integration with Apple Health, Whoop, or Oura at the depth Function offers

Mito Health Mito Health Membership - buyer FAQ
Mito Health vs Function Health - which one?
Priced almost identically, so it comes down to features. Function ($365/yr) has 160+ biomarkers, founded 2022, two included draws a year, a larger community, and no past-lab upload. Mito ($349/yr Core) has 100+ biomarkers and one annual draw, but includes a 1:1 MD consult, allows past-lab uploads (insights work from day 1), surfaces a biological-age readout, offers genetics + microbiome add-ons, and tiers up (Pro $699, Ultra $1,899) to advanced and cancer screening. If past-lab upload or biological age matters to you, Mito; if you want the wider panel and two draws, Function. For buyers already on Function, don't migrate.
What does past-lab integration actually do?
Upload bloodwork your PCP ordered (or labs from previous platforms like Quest, LabCorp, or other DTC providers) and Mito's AI uses that historical data to identify trends from day one. Function only tracks data from its own draws, so your first year is partially educational. If you already have several years of bloodwork sitting in patient portals, Mito's integration delivers immediate insights vs waiting 12 months for Function to build a trend baseline.
Are there tiers above Core?
Core ($349/yr) covers 1 annual draw, 100+ biomarkers, AI insights, biological age, and a 1:1 MD consult, and is the right tier for most buyers. Pro ($699/yr) adds 5 advanced tests (heavy metals, omega-3/6, cholesterol particle, IGF-1, cystatin-C). Ultra ($1,899/yr) adds a multi-cancer early-detection test and a gut-health test. A la carte add-ons (gut health $239, DEXA $59) are available without upgrading. Confirm current pricing on mitohealth.com before committing.
Does Mito prescribe TRT or peptides?
No - Mito is diagnostic-only. If labs surface a low testosterone or hormone imbalance, Mito flags it and recommends follow-up with a prescribing clinician (your PCP, an endocrinologist, or platforms like Marek Health, Hone, Maximus). For longevity-pro buyers, the right play is Mito for diagnostics + Marek/Hone for active prescription work.
Is HSA/FSA eligible?
Yes via Flex - same partner Sunlighten uses for HSA-eligible sauna purchases. The membership and add-on tests qualify under most plan administrators. Effective cost is 22-37% lower depending on your tax bracket. The Flex enrollment flow runs alongside the regular Mito signup, adds 1-2 days of paperwork before active membership.
