Function Health Alternatives (2026): 4 Cheaper Ways to Track Your Biomarkers
Function created the longevity-membership category, but it is not the only option, and rarely the cheapest. Here are four alternatives that track the same biomarkers for less.

Function Health productized the executive physical into a $365/year membership and crossed 100,000+ members - it created the longevity-biomarker category. But $365/year is real money, the waitlist comes and goes, and for a lot of buyers the membership scope is more than they need. The good news: the underlying thing you want - comprehensive bloodwork, tracked over time, with insights on top - is available several other ways, most of them cheaper.
Here are the four alternatives worth comparing, and exactly who each one fits.
First, what you are actually paying Function for
A Function membership bundles four things: a broad biomarker panel (160+ markers), two draws a year, AI insights on your results, and physician review on flagged values. Any alternative is really a question of which of those you need, and how much breadth is enough.
Alternative 1: Mito Health - the closest like-for-like, at a much cheaper entry
Mito is the most direct substitute on what you get (comprehensive panel, AI insights, clinician review, year-over-year tracking) and it is now far cheaper to start: the Essential panel is a one-time $89.61 at the member price, or $125.51 without joining, against Function's $365 a year. Membership is optional at $9 a month, cancel anytime, and there is nothing to renew. Mito lets members upload past lab PDFs so that history reads together with new results and each biomarker trends over time, surfaces a biological-age readout, and offers genetics + gut-microbiome add-ons plus deeper panels (Core $198.69, Pro $324.47, Ultra $1,506.98 at member prices) that layer in advanced and cancer screening, all verified on mitohealth.com on 15 September 2026. Prices and marker counts vary by state and by the sex-specific panel you select, New Jersey, New York and Rhode Island run higher through BioReference, and lab draw fees are itemized at checkout. Function counters with a wider 160+ marker panel and two draws inside the annual price, where every Mito panel and draw is its own line item. If past-lab upload, biological age, or a cheaper way in matters to you, Mito is the pick. See the full head-to-head in Mito Health vs Function Health.
Superpower belongs in that same sentence now, and did not a few months ago. It runs 150+ biomarkers for $349 a year, sixteen dollars under Function, verified on superpower.com on 11 September 2026. Like Mito it accepts uploads of external bloodwork, so it starts from your history rather than from zero, and it is the only one of the three that will send a phlebotomist to your home, as a $119 add-on. Calling it cheaper than Function would be dressing up a sixteen dollar gap on a panel with ten fewer markers, so we do not. Call it a genuine price-match with Function, bought a different way.
Alternative 2: SiPhox Health - skip the lab and the needle entirely
SiPhox is the at-home route: you collect a small sample from your upper arm with their no-needle EasyDraw device, mail it back, and get up to 60 biomarkers with an AI action plan in about a week, from kits starting around $99. It trades panel breadth (60 vs 160+) for convenience and price, which makes quarterly testing realistic instead of twice a year. For most buyers the longevity-useful signal is the trend line, and testing four times a year at $99 beats twice a year at $365 for watching markers move. HSA/FSA eligible.
Alternative 3: HealthLabs - pay a la carte, no membership at all
If you do not want a subscription, HealthLabs lets you order individual tests (or a custom bundle) directly, draw at a partner lab, and get results - no membership, no recurring bill. You lose the curated panel and AI layer, but you gain total control over what you test and pay only for what you order. The right pick for buyers who already know which markers they care about.
Alternative 4: Hume Body Pod - the body-composition layer Function does not cover
Not a blood test, but worth naming: a lot of what people open a Function membership to track (am I gaining muscle, losing fat, is my metabolic rate moving) is body-composition data, not bloodwork. The Hume Body Pod tracks lean mass, fat, and metabolic rate at home for a one-time ~$229, far cheaper than repeated DEXA scans, and a strong complement to whichever blood panel you choose, especially for GLP-1 users.
The honest comparison
| Option | Price | Biomarkers | Model | Best for |
|---|---|---|---|---|
| Function Health | $365/yr | 160+ | Membership | Wider panel + two draws + largest cohort |
| Mito Health | from $89.61/panel | 117 to 178, sex-specific | One-time panels, $9/mo membership optional | Member past-lab upload + biological age, cheaper entry |
| SiPhox | ~$99+/kit | up to 60 | At-home kit | No-needle, frequent testing |
| HealthLabs | per test | your choice | A la carte | No subscription, full control |
| Hume Body Pod | ~$229 once | body comp | Device | Muscle/fat/metabolic tracking |
So which alternative?
- Want past-lab upload and a biological-age readout, with no annual commitment → Mito Health
- Hate needles and lab visits, want to test often → SiPhox
- Do not want a subscription → HealthLabs
- Care about body composition, not just blood → Hume Body Pod
- Want the labs plus a clinician team that acts on them → Geviti (the care-tier lane, covered below)
- Genuinely value Function's wider 160+ panel, two draws, brand, and refined app, and the $365 is fine → stay with Function Health. It is a good product, just not the only one.
The opposite direction: when the answer is more, not less
Every alternative above beats Function on price by selling you less: fewer markers, fewer draws, or testing without a membership. There is also a lane that goes the other way, and it answers a different question. Test-and-track memberships hand you data and leave the acting to you; a newer test-and-act category wraps the labs in an actual care team.
Geviti is the clearest example of that care tier. Geviti Plus runs $127 a month, or $1,529 billed annually, verified August 2026 against the brand's published pricing: a 100+ marker panel drawn twice a year, quarterly video visits with a longevity specialist and a clinician, a personalized blueprint, custom supplement packs shipped to you, and clinician-prescribed therapeutics where clinically appropriate. The membership is available in 47 states (all but AK, RI, and HI), with prescribing coverage brand-stated at 41, and it is HSA/FSA eligible. A $0 free tier lets you upload existing labs and use the Makor AI assistant before committing.
At roughly four times Function's $365 it is not an alternative on price, and we do not list it as one. It is what you compare when the constraint was never the cost of the panel but what happens after the results land. Geviti is not an affiliate partner and this mention is editorial; the comparison is simply incomplete without the care-tier pole.
The longevity-stack frame
Biomarker tracking is the foundation the rest of a longevity stack sits on - without it, your supplements and hardware run on guesses. But the foundation does not have to cost $365/year. Pick the option you will actually keep using (frequency and adherence matter more than panel breadth), test consistently for 24+ months, and let the trend lines tell you whether the rest of your stack is working.
