Function Health Vs Superpower — Which Platform Is Actually Better?

Function Health and Superpower are the two most-searched longevity-testing platforms in the US, and they price identically: $499 a year, 100+ biomarkers, two draws included, results in an app. Their base panels overlap by roughly 90%, so the marker list is not where this decision gets made. What separates them is how results are presented, how each routes you to a draw site, what sits in the add-on catalog, and how long each has operated at scale. Neither includes a physician consult in the membership, and neither prescribes.

What each platform actually is

Function Health

Function Health launched in 2023 with Kevin Rose and Dr. Mark Hyman on the founder page, and sells a $499 annual membership. That buys a 100+ biomarker base panel drawn twice a year across heart, metabolic, thyroid, immune, nutrient, hormone, kidney and liver, blood count, and heavy-metal groups. Draws route through Quest and LabCorp partner sites. You receive clinician-written commentary on every result, flagged deltas across time, and a full PDF and CSV download of the raw data. Results typically post 7 to 14 days after the draw. The membership does not include a live physician consult — those are sold separately at $150 to $300 — and Function Health does not prescribe.

Superpower

Superpower sells the same $499 annual membership and the same 100+ biomarker base panel drawn twice a year. Draws run primarily through Quest, with at-home phlebotomy expanding in select markets. The product is built around a consumer mobile app: guided onboarding for people who have never had a broad panel drawn, coaching prompts on flagged results, and downloadable raw results. Clinician-written commentary is included. Live consults and concierge chats are add-ons at $150 to $300 and up, and targeted retests between the two included draws are priced per panel. The membership does not include a physician consult, and Superpower does not prescribe.

Side by side on the standard rubric

Every platform comparison on this site uses the same ten-row rubric, so you can cross-shop any two head-to-head on identical criteria.

What each actually costs

Both list $499. Neither total lands at $499 for most members, and the reasons differ.

Function Health's $499 covers the membership and both draws. The published year-one range of $750 to $1,200 assumes one advanced panel and one physician consult layered on top, which is what most members end up buying. There is no one-time onboarding fee, so year two starts at the same $499 rather than dropping. The cost that catches people out sits off the pricing page entirely: if no Quest or LabCorp partner site is within reach of your ZIP, a draw at a non-partner location runs $30 to $80, and with two included draws you pay it twice.

Superpower's $499 covers the same membership structure, and its published year-one range is also $750 to $1,200 once one add-on panel and one consult are included. Year two also starts at $499, with no onboarding premium to fall away. The variable that moves Superpower's total is the targeted retest. Because you can retest a single area between the two included draws, and each retest is priced per panel, engaged members tend to accumulate several small purchases across the year rather than one large one. Multiple add-ons plus specialist consults push either platform past $1,500.

Where Function Health leads

• Operating history. Launched in 2023 and running at scale roughly two years longer than Superpower. More draws processed means more edge cases already handled.
• Clinical trend view. Ranges, deltas, and year-over-year movement are laid out the way a physician reads a chart, which makes the second and third draws more useful than the first.
• Add-on catalog breadth. A longer a-la-carte list including advanced heart panels, partner-run cancer screening, hormone deep-dives, and food sensitivity testing at $100 to $400 each.
• Two partner lab networks. Quest plus LabCorp covers more ZIPs with an in-network draw site, which lowers the odds of paying the $30 to $80 non-partner fee twice a year.
• Published turnaround. Function Health states a 7 to 14 day window from draw to posted results, so you can plan a draw around a date you need the data by.

Where Superpower leads

• App experience. A consumer-app interface that presents results as a guided sequence rather than a table, which lowers the effort of a first read.
• Feature velocity. Ships new features and panel expansions faster than anything else in this category, so the product you buy in month one is not the product you hold in month twelve.
• Onboarding. A guided first-panel flow built specifically for people who have never had a broad biomarker draw and do not know what any of the markers mean.
• At-home draws. At-home phlebotomy is live in select markets, removing the partner-site trip and the non-partner draw fee where it is offered.
• Mid-year retests. You can retest a single area between the two included draws, priced per panel, instead of waiting six months for the next full sweep.

Trade-offs to weigh

Function Health trade-offs

• Clinician time is an add-on. The membership includes written commentary, not a conversation. A live consult is $150 to $300 per session on top of the $499.
• No prescription pathway. An out-of-range result routes back to your own physician. If you do not have one, the result is information without a next step.
• Access has been waitlisted. Availability has historically opened in waves through the year, so the date you subscribe and the date you draw are not always close together.
• Minimal app onboarding. The interface assumes you already know roughly what a lipid panel or a thyroid marker is. First-time testers do more of the interpretive work themselves.

Superpower trade-offs

• Clinician time is an add-on. Same structure as Function Health — commentary included, live consults and concierge chats at $150 to $300 and up.
• No prescription pathway. Flagged results are referred outward. Superpower does not treat and does not write prescriptions.
• Shorter operating history. Fewer years at scale than Function Health, which matters most for the parts of the service you only meet when something goes wrong with a draw or a result.
• Costs accumulate in small pieces. Mid-year retests are billed per panel and at-home draws exist only in select markets, so the year-one total is harder to predict at signup.

Who should pick each

Pick Function Health if: you are comfortable reading a lab report, you already have a physician or intend to bring results to one, and you want the wider add-on catalog behind the base panel. It also fits if both Quest and LabCorp have sites near you, since the two-network footprint lowers the odds of paying a non-partner draw fee twice a year. Budget $750 to $1,200 for year one.

Pick Superpower if: this is your first broad biomarker panel and you know a dense clinical table will not hold your attention past week one. It also fits if at-home phlebotomy is live in your market, or if you would rather retest one area mid-year than wait six months for the second included draw. Budget the same $750 to $1,200 for year one.

Who should pick neither

Both memberships answer one question — what are my numbers — and hand the next step back to you. If you are testing because of a specific symptom, or because you expect the results to require treatment, $499 buys a document rather than a resolution. Three alternatives are usually a better fit, listed alphabetically.

• Hone Health — hormone-focused, with a clinician and a prescription pathway included rather than sold as an add-on.
• Lifeforce — a narrower panel with expanded hormone coverage, a bundled clinician, and prescriptions where indicated.
• All doctor-led options — the full set compared on the same ten-row rubric, so you can see what bundling a clinician actually costs.
• Your own physician, through insurance. An in-network primary care visit with physician-ordered labs covers a much narrower panel — typically 10 to 20 biomarkers — but it comes with somebody accountable for the result. If you have one symptom rather than general curiosity, start there.

Can you use both?

Running both costs $998 a year before any add-ons, and the base panels overlap by roughly 90%. You would pay twice for most of the same markers, drawn at largely the same partner labs, on the same semi-annual cadence. For nearly everyone that is a duplicated purchase rather than a broader picture. The add-on catalogs diverge more than the base panels do, so if the draw is a specific advanced panel one platform sells and the other does not, buying that single panel is far cheaper than buying the second membership to reach it.

The one situation where an overlapping year is defensible is migration. Trend history does not transfer between platforms — switching means starting a new baseline from zero. If you already hold two or three years of data on one platform and want to move, overlapping for a single year gives you a same-period draw on both, so the old history and the new one share a reference point. Drop one at the next renewal. There is a cheaper version of the same move: both platforms export full raw results, so you can download the file, cancel, and hand the history to whoever reads your labs next.

What the rubric does not capture

The rubric row that reads "clinician-written commentary" at both platforms hides a distinction a table cannot make: there is a difference between text attached to a result and a conversation about it. Neither membership includes the conversation. The commentary is written against the number, not against you — it does not know your medications, your training load, or that a parent had a cardiac event in their fifties. Both sell live consults at $150 to $300, and at both platforms that add-on is where individualized interpretation actually happens. Expect at least one flagged marker on a panel this wide, and expect most flags to mean nothing on their own; our normal versus optimal guide explains how reference ranges are built and which patterns warrant a clinical conversation.

Cadence is the second thing the table understates. Two draws a year is the included rhythm at both, and semi-annual is too slow to titrate anything. Change a supplement, a dose, or a training block in month one and your next included data point is month six — long after you would want to know whether the change worked. Superpower sells a targeted mid-year retest priced per panel; at Function Health an additional draw is a separate purchase. Either way, measuring faster than twice a year is a cost that neither $499 covers.

Month one flatters both platforms: a fresh panel, a full report, a list of things to change. Month six is where they separate, and the variable is you rather than the software. Function Health's trend view rewards a member who returns on their own to compare deltas. Superpower's prompts are built to pull back the member who otherwise would not open the app. No rubric row scores that, because the answer depends on your habits. Two structural facts do belong in the decision: both bill annually, so canceling mid-year does not refund an undrawn panel, and both depend on a draw site being near you. Function Health solves that with two lab networks, Superpower with at-home markets — check which one covers your ZIP before you pay either.
