Function Health vs Superpower: What Each Membership Includes
Function Health vs Superpower from their own pages: biomarker counts, price and billing, state availability, results delivery and clinician-review claims.

We have not tested products ourselves. How we researchQuick verdict
Both sell a yearly blood-test membership run through Quest labs with two draws a year. Function lists $365 a year and 160+ tests; Superpower lists $349 a year (price may vary in New York and New Jersey) and 150+ biomarkers. The real differences are state coverage, at-home draw fees and what each says about doctors. Neither is medical advice, and no trial shows that broad panels in healthy adults improve outcomes.
Talk to your doctor first. This is general information, not medical advice. Supplements and devices can interact with medicines and health conditions. We quote study protocols for context and do not recommend doses.
The short answer: the two memberships are close. Both sell two blood draws a year at Quest labs (or at home), with results in an app and a protocol or action plan. Function Health lists $365 a year for 160+ tests; Superpower lists $349 a year for 150+ biomarkers, both read on their own sites on 2 Oct 2026. Neither claims to replace a doctor, and in their own legal text both say they are not medical providers. Whether a broad panel helps a healthy adult is unproven (see the evidence section), so choose on price, location and how you want results explained. This is not medical advice.
Side by side, from each company’s pages
| Attribute | Function Health | Superpower |
|---|---|---|
| List price | $365 a year, “charged annually” (pricing) | $349 a year, $0.96 a day; “pricing may vary for members in New York and New Jersey” (site) |
| Biomarkers (as stated) | 160+ lab tests a year: 100+ at the annual test, 60+ at a mid-year test 3 to 6 months later (FAQ) | 150+ biomarkers a year across two draws; the same page also says “100+ biomarkers as a baseline” |
| Draws a year | Two; the mid-year test must be used before renewal and does not roll over | Two: baseline and a retest |
| Lab | Quest, 2,000+ locations; at-home draw by a licensed specialist | Quest, 2,000+ locations; at-home “at an additional cost” |
| Where | “48 states (but not yet Rhode Island, Hawai’i, or Puerto Rico)” per the FAQ; the pricing-page footnote says the $365 applies “in all states except New York and New Jersey”, and the FAQ says testing in NY and NJ can cost more | A list of 42 places marked live on its site (41 states plus DC, including New York, New Jersey and Rhode Island; not listed: Hawaii, Maine, Montana, New Hampshire, North Dakota, South Dakota, Vermont, West Virginia, Wyoming) |
| Cancel and refunds | Cancel and rejoin any time, no pauses; “does not offer refunds for prior payments” | “Cancel anytime, no fees”; membership stays active through the paid year |
| Results delivery | First results “typically” within 48 hours of testing; download as PDF to share with your doctor | “Typically ready in about a week” in the FAQ; “10 days or less” in the price box; delivered in the app |
| Extras | Add-ons: MRI ($999 for the annual scan per the FAQ), Galleri cancer test, ApoE | Biological age and 17 health scores, an AI chat, wearable sync, add-on tests such as the Galleri screen |
| Data | Upload past results; delete your data any time (permanent) | Upload past labs; export and delete any time |
Read the footnotes before paying: Function’s FAQ says it charges “annually at $365”, while its legal text calls the $365 the “first-year membership”, so check the renewal price at checkout. Superpower’s page says the membership stays active through the paid year and does not state a renewal price.
What the doctor claims actually say
- Function: “Clinicians review every result and flag issues”; each result comes with explanations “created by top doctors”, and Function names its Chief Medical Officer. In the same footer it says it is “not a laboratory or medical provider” and “does not offer medical advice”. Urgent results are followed up by a healthcare provider, per the FAQ.
- Superpower: “Clinician-reviewed protocols” and “AI for everyday health questions. Real clinicians for added one-on-one support.” Its terms say it “is a technology company” and “not a healthcare provider”, and that content is “not tailored to you”. It lists a medical advisory board on its site.
Read together: both attribute review to clinicians, and both disclaim medical advice in their terms. We cannot verify who reviews what or how long it takes, and we do not describe either as medically reviewed.
Which tests overlap
Function says it goes beyond a standard lipid panel with “Apolipoprotein B, Lipoprotein A, and Lipoprotein Particle Size”. Superpower’s visible lists show categories such as hormones and thyroid (19 biomarkers), cancer and other risks (10, including PSA and hs-CRP), heart and metabolic (41) and aging (3, including a pace-of-aging and a biological-age test), but the page text we read did not name ApoB or Lp(a), so we cannot say whether it includes them. Compare marker lists on each company’s own site before paying. Our biomarkers guide explains what the common markers measure, and biological age tests covers what the age scores can and cannot show.
What the evidence says
Evidence grade: weak for outcome benefit, because no trial tests these products. The nearest evidence is a 2019 Cochrane review of randomised trials of general health checks in unselected adults: 15 trials with 251,891 participants reported outcomes and found little or no effect on total mortality (RR 1.00, 95% CI 0.97 to 1.03, high certainty) or cancer mortality. Those were checkups, not consumer panels, and many markers they offer are useful in specific clinical settings. The practical point: a result outside the reference range needs a clinician to interpret it, and more markers also means more chances of an out-of-range flag. See at-home blood tests and longevity labs for other routes.
Who each suits
- Pick Function if you are in one of its 48 states, want a single flat annual price with a stated mid-year retest and add-on imaging, and are comfortable that refunds are not offered.
- Pick Superpower if you want the lower list price, app-based protocols and wearable sync, and live in a state on its list (check the list first).
- Pick neither if you want a doctor to order and discuss tests: both disclaim medical advice.
Method note
Researched from each company’s pricing, FAQ and terms pages, and PubMed, checked 2 Oct 2026. Prices and counts are as the companies state them and change often. We did not buy either membership. General information, not medical advice. Longevity Intel is not paid by either company.

Common questions
Is Function Health or Superpower cheaper?
On the lists we read on 2 Oct 2026, Superpower is $349 a year and Function is $365 a year. Function's FAQ says it charges "annually at $365", but its legal text calls $365 the first-year membership, so confirm the renewal price at checkout. Both say prices differ in New York and New Jersey. At-home draws cost extra at Superpower; Function offers them but we did not find the fee stated.
Do Function Health and Superpower replace my doctor?
Neither says so. Function states it is not a laboratory or medical provider and does not offer medical advice. Superpower's terms say it is a technology company, not a healthcare provider, and does not provide medical advice. Take results to your own clinician.
Will a broad blood panel improve my health?
A 2019 Cochrane review of 17 randomised trials of general health checks in adults (251,891 participants in the 15 that reported outcomes) found little or no effect on total or cancer mortality. Those trials tested general checkups, not these panels, so it is the closest evidence rather than a direct answer.
