Superpower vs Function Health: the short version
These two get lumped together because they look alike on the surface: pay once a year, get a comprehensive blood panel, see your results in a polished app instead of a faxed PDF. But the gap between them is real, and it comes down to one question. Do you want the lower-friction yearly baseline, or do you want the deeper, twice-a-year clinical workup?
Superpower is built around a single annual draw and a price that does not make you wince. Function Health is built around breadth and a second look six months later. Neither is a doctor, and neither diagnoses you. Both are screening and tracking services that hand you numbers and trends so you can have a smarter conversation with an actual clinician.
If you only remember one line from this comparison, make it this: Function Health buys you more data and more frequent checkpoints, Superpower buys you a cheaper, simpler baseline with stronger guidance on what the numbers mean. The right choice depends entirely on which of those two problems you are actually trying to solve.
Price: the cleanest difference in this comparison
This is where Superpower vs Function Health stops being close. Superpower is $199 per year. Function Health is $365 per year. That is roughly an 83 percent premium for Function, and you should know exactly what that premium buys before you pay it.
One caveat on Superpower pricing: in New York and New Jersey, the membership is $399 instead of $199 because of state lab rules, not a hidden upsell. If you live in either state, the price advantage narrows sharply, and you should weigh the two more evenly on features rather than cost.
For everyone else, Superpower’s $199 is the entry point that makes a yearly full-body draw feel routine instead of indulgent. That low annual number is the single biggest reason most first-time testers should start here.
Biomarkers and breadth: Function goes wider
If raw marker count is your scoreboard, Function Health takes it. It tests 160+ biomarkers per year against Superpower’s 100+, and once you fold in Superpower’s calculated ratios the gap is narrower than the raw headline numbers suggest. Function also bundles a urinalysis, which Superpower’s blood-only panel does not.
Here is the honest nuance most listicles skip: past a certain point, more markers is not automatically more insight. The markers that move the needle for a healthy adult, the metabolic, lipid, thyroid, inflammation, liver, kidney, and key vitamin panels, are covered well by both services. Function’s extra markers add real value if you are managing something specific or you simply want the most complete snapshot money can buy. For a clean yearly baseline, Superpower’s 100+ already covers the questions most people actually have.
Who the wider panel is for
Choose Function’s breadth if you are a data maximalist, you are tracking a known condition with your clinician, or you want urinalysis folded in without ordering it separately. Choose Superpower if you want the high-signal markers without paying for a longer list you may never look at twice.
Draws and retest cadence: one draw vs two
Superpower includes one comprehensive annual blood draw. Function Health includes two draws per year plus a built-in 6-month retest, so you see how your numbers move across the year, not just where they sit once.
That retest cadence is a genuine Function advantage if you are actively changing things: a new training block, a medication, a diet overhaul, a supplement stack you want to validate. Seeing a marker shift at the 6-month mark is more useful than guessing for a full year.
If you are mostly establishing a baseline and tracking slow, year-over-year drift, one annual draw is plenty, and you can always add a follow-up test if something looks off. For most people not running an active experiment on their own body, the second draw is a nice-to-have, not a need-to-have. Function health vs Superpower really comes down to this: are you optimizing in real time, or are you watching the long arc? The first case wants two draws. The second is well served by one.
Clinician review: who actually looks at your results
Both services route your bloodwork through accredited labs and frame results so a layperson can follow them, and both stop short of being your doctor. The practical question is what happens after the numbers land. Function Health leans into a more clinically thorough presentation, and its longer panel plus urinalysis gives a reviewing clinician more to work with. Superpower’s edge is interpretation: 17 plain-language scores plus an AI concierge that can walk you through what a flagged marker tends to mean and what to ask about.
Neither replaces a sit-down with a physician, and you should not treat either as a clinical sign-off. Think of both as the prep work that makes a doctor visit far more productive, because you walk in with structured data instead of vague symptoms. If you already have a clinician you trust, either service feeds them useful inputs; if you do not, Superpower’s guided layer does more to keep you from misreading your own results.
Results experience: scores, action plan, and AI
Where Superpower quietly pulls ahead is in turning numbers into something you can act on. Beyond the raw values, it gives you 17 plain-language health scores, a personalized action plan, and an AI concierge you can chat with about your specific results. That last part matters: instead of staring at a flagged value and Googling at midnight, you can ask follow-up questions in context.
Function Health also delivers results in a clean dashboard and is more clinically thorough on the data side, but its AI chat layer is newer. If a conversational, guided interpretation is the feature that would actually get you to use your results, Superpower’s concierge is the more mature experience today.
A theme users commonly report across both services is that the app and the plain-English framing are what keep them engaged. A pile of out-of-range flags with no narrative tends to get ignored. Both companies clearly know this; Superpower just leans into the guided, score-first presentation a bit harder. The action plan also nudges you toward a few concrete next steps rather than leaving you with a wall of values, which is the difference between a test you act on and a test you forget.
Full-body lab membership: 100+ biomarkers, doctor-reviewed, tracked over time.
What neither one is: a YMYL reality check
Both Superpower and Function Health are screening and tracking tools, not diagnostic clinics, and nothing here is medical advice. A single out-of-range marker is a flag to investigate, not a diagnosis. If any result falls outside the normal range, especially anything related to your heart, kidneys, liver, or blood sugar, review it with a licensed clinician before you act on it or change a medication.
Used that way, as a structured early-warning system that hands real numbers to a real doctor, either service earns its keep. The mistake is treating the dashboard as the final word. It is the start of the conversation, not the end of it.
The verdict: who each one is for
In the head-to-head, Function Health wins on breadth and cadence: 160+ biomarkers, two draws, a urinalysis, and a 6-month retest. If you want the most clinically thorough annual workup and you will use the extra data, the $365 is defensible.
But for the person this article is really for, the health-conscious adult who wants a trustworthy yearly baseline, clear scores, and a price that does not require deliberation, Superpower is the smarter starting point. You get 100+ biomarkers, 17 health scores, a personalized action plan, and an AI concierge for $199 a year. It delivers the insight most people actually act on, at well under half the price and far less of the friction.
Our recommendation: start with Superpower for your baseline this year. If you find yourself wanting twice-yearly draws or the widest possible marker list, Function Health is the natural step up.

Frequently asked questions
Is Superpower or Function Health cheaper?
Superpower is cheaper at $199 per year versus Function Health at $365 per year. The exception is New York and New Jersey, where Superpower is $399 due to state lab rules, which narrows the gap. Outside those two states, Superpower is the clear value pick in the Superpower vs Function Health comparison.
Does Function Health test more biomarkers than Superpower?
Yes. Function Health tests 160+ biomarkers and adds a urinalysis, while Superpower tests 100+ biomarkers plus a set of calculated ratios on top of the headline panel. More markers can mean more data, but for a healthy adult building a baseline, both cover the high-signal panels that matter most.
How often do you get tested with each one?
Superpower includes one comprehensive blood draw per year. Function Health includes two draws per year plus a built-in 6-month retest, which is better if you want to track changes mid-year. For slow, year-over-year tracking, Superpower’s single annual draw is usually enough.
Which is better for someone testing for the first time?
For most first-timers, Superpower is the better starting point: lower price, plain-language health scores, a personalized action plan, and an AI concierge that helps you understand results. Function health vs Superpower tilts toward Function only if you specifically want maximum breadth and twice-yearly draws out of the gate.
Can these tests replace seeing a doctor?
No. Both Superpower and Function are screening and tracking services, not diagnostic clinics, and neither replaces medical care. Any result outside the normal range should be reviewed with a licensed clinician before you act on it.
