Mito Health vs Function Health 2026: Which Membership Wins for Longevity Buyers
Mito now sells one-time panels from $89.61 while Function is $365 a year, so the cheaper entry is Mito: past-lab upload and biological age vs Function's wider panel and two included draws. Here's the actual decision framework.

Function Health became the breakout longevity diagnostic platform of 2024-2025 - productizing executive-physical biomarker tracking into a $365/year membership and crossing 100,000+ members within 18 months. The brand created the category. Mito Health, founded more than three years ago by its own account and US-focused since January 2025, is the direct alternative, and it now sells its panels one at a time from $89.61 at the member price with no annual commitment, built around past-lab upload and a biological-age readout.
The honest answer on which to pick depends on what you actually want from a biomarker platform.
The category framing
Both Mito Health and Function Health are comprehensive biomarker platforms, but they no longer sell the same way. Function is a membership: $365 a year, two draws, results across its panel. Mito sells each panel as a one-time purchase from $89.61, with an optional membership at $9 a month, cancel anytime, that unlocks the member price on every test. What both deliver: 1. A comprehensive panel drawn at a partner lab (Quest, Labcorp or BioReference), or at home by a phlebotomist for a flat $99 in most US states 2. 100+ biomarker results 3. AI-driven insights highlight biggest deltas + abnormal markers 4. Clinician review of the full panel before your analysis and action plan are finalized 5. Year-over-year tracking dashboard
Both are a meaningfully different product than: - Single-visit panels with no tracking layer (InsideTracker, Marek Health single-visit) - a one-off readout, no longitudinal dashboard - Concierge medicine (Lifeforce, Forward) - ongoing physician relationship, much higher cost ($2,000-5,000/yr) - Direct lab orders (Ulta Lab Tests, Walk-In Lab) - buy individual tests à la carte, no insights or interpretation
This category fits buyers who want consistent year-over-year biomarker tracking with AI-driven insights, without the cost of full concierge medicine.
Spec comparison

Mito prices and marker counts vary, verified 2026-09-15: New Jersey, New York and Rhode Island run through BioReference at higher prices, where Core is $463.62 member and $649.23 non-member, counts reflect the sex-specific panel selected at checkout, collection is a blood draw at Quest, Labcorp or BioReference or an at-home phlebotomist visit for a flat $99 in most US states, and lab draw fees are itemized at checkout. Rhode Island has no Mito lab location, so buyers there visit a lab in a neighbouring state.
Where Function Health wins
- Brand momentum + community: Function has 100K+ active members and the strongest brand presence in the longevity-membership category. Andrew Huberman's public endorsement drove ~80% of early-2024 growth. For buyers who value brand presence and category-defining positioning, Function is the safer choice.
- Operational maturity: Function had an 18-month head start. Lab partner integrations, member dashboard, and result-delivery cadence are more refined.
- Network effects: Larger member base means richer cohort comparison data ("how does my ApoB compare to other 35-year-old men in my fitness percentile?"). This is a real signal advantage.
- Single-product focus: Function does one thing well - comprehensive biomarker membership. No add-on upsells distract from the core experience.
- Wider panel + two included draws: Function's 160+ marker panel and two draws a year come in one $365 price, where Mito prices every panel and every draw fee separately and only its Pro and Ultra panels reach that marker count.
Where Mito Health wins
- Past-lab upload: Mito members can upload bloodwork a PCP or a prior platform already ran, so those results read together and each biomarker trends over time. Mito states the file rules as PDF, JPG or PNG, under 10MB and not password protected.
- Biological-age readout: Mito surfaces a biological-age number alongside the panel, a longevity-native metric Function does not headline.
- Panel range + add-ons: Mito sells one-time panels (Essential $89.61, Core $198.69, Pro $324.47, Ultra $1,506.98 at member prices) and offers a whole-genome sequencing kit plus a gut microbiome kit, sold standalone or bundled into Ultra. Cancer screening comes from Galleri inside the Ultra panel. Mito states its genetics product is a consumer wellness and educational product that does not screen for or predict disease. Function doesn't currently offer these.
- Cheaper entry, nothing to renew: Essential is $89.61 as a one-time member purchase, or $125.51 without joining, against $365 a year for Function. You can buy one panel, decide what the insights are worth to you, and stop.
Where neither one is the right answer
- You need clinician-led hormone optimization (TRT, peptides, GLP-1) → Marek Health or Lifeforce is the right tier - these include active prescribing relationships, not just lab insights
- You only want a one-time baseline → InsideTracker at $300 single-visit is built for spot-baselines, and Mito's Essential panel now works the same way for less since there is no annual commitment to sign
- You want full whole-body imaging in addition to bloodwork → Mito now resells Prenuvo full-body MRI and BodySpec DEXA as standalone purchases, subject to state availability (MRI in 11 states plus DC, DEXA in 6 states). You can also buy direct from Prenuvo or Ezra
- You're already getting comprehensive labs through your existing physician → ask for a copy of the panel. Mito presents upload as a membership feature at $9 a month, so that is the cheapest way to get existing results trending without buying a new panel
The decision framework
Pick Function Health if: - You want the wider panel (160+ markers) and two included draws a year - Brand presence and the largest member cohort for comparison data matter to you - You value the most refined product experience after 18+ months of iteration - You don't have past labs to upload (Function can't use them anyway)
Pick Mito Health if: - You have past bloodwork to upload and want it trending alongside new results - A biological-age readout matters to you - You want add-on flexibility (whole-genome sequencing, gut microbiome), or the option to step up to Ultra, which adds Galleri multi-cancer early detection (not available in NY, NJ or RI) and an at-home gut microbiome kit - You want to start cheap and stay flexible: $89.61 for the Essential panel as a member, or $125.51 without joining, against $365 a year, with nothing to renew
Pick InsideTracker if: - This is your first comprehensive lab panel and you want to test the experience without annual commitment - You want a single $300 panel with blood plus DNA rather than a recurring $365 membership bill
Pick Marek Health or Lifeforce if: - You need active hormone optimization, not just biomarker tracking
The longevity-stack frame
For Lifespan Vault's longevity-focused readership, biomarker membership is foundational infrastructure. Without baseline labs and longitudinal tracking, the rest of the longevity stack (supplements, hardware, protocols) is operating on guesses. The cost of either Mito Health or Function Health is genuinely small relative to a $5K-50K longevity hardware budget.
Pick one and stay with it for 24+ months. The longitudinal data is what makes it valuable - a single panel gives you a baseline; year-over-year is what tells you whether your stack is working.
