Quick verdict: In the Superpower vs Function Health matchup, both run a real venous blood draw, score a 100-plus biomarker panel, and hand you a polished dashboard instead of a faxed PDF. The difference is what you are buying. Superpower is $199 a year for a single comprehensive annual draw, 100-plus biomarkers, plain-language health scores, an action plan, and a 24/7 care team plus AI concierge. It is the value pick for most people who want a once-a-year full-body baseline they will actually understand. Function Health is $365 a year and splits its testing into a 100-plus biomarker annual draw and a roughly 60-plus biomarker mid-year retest, with a clinician writing a summary of your results. It wins if you want a structured twice-a-year cadence and a written clinician review built into the price. For the typical health-conscious adult testing for the first time, we recommend starting with Superpower.

What both services actually are

Strip away the marketing and Superpower and Function Health are the same species: a consumer membership that orders a wide blood panel through a major reference lab, draws you at a Quest location, and returns your numbers in a clean app with normal ranges, flags, and plain-English context. You pay once a year. You do not need a doctor’s order to start. Neither one is a clinic, and neither one diagnoses you.

That last point is the one people skip past, so we will say it plainly here and come back to it later. Both services are screening and tracking tools. They tell you where your numbers sit, flag what is out of range, and show how things move over time. They do not treat you, prescribe for you on the basis of a flag, or replace a relationship with a clinician. What they do extremely well is turn a vague “I should probably get my bloodwork checked” into a structured dataset you can act on, and a far more productive conversation when you do see a doctor.

The reason these two get compared constantly is that they launched into the same gap: people who want more than the three or four markers a standard physical checks, who do not want to argue with insurance about whether ApoB is “medically necessary,” and who want results in an app they will open more than once. Both nailed that gap. The interesting question is not whether either is good. It is which one fits how you actually behave.

Head-to-head: the criteria that matter

Marker counts and monthly-equivalent pricing make for tidy tables, but the decision really turns on seven things. Here is each one, called honestly.

Biomarkers and breadth

On paper this looks like a Function win, and the way it is usually marketed (“160-plus”) makes the gap sound bigger than it is. Here is the precise picture. Superpower tests 100-plus biomarkers in one annual draw, then layers calculated ratios on top of the raw values. Function Health tests 100-plus biomarkers at your annual draw and roughly 60-plus more at the mid-year retest, which is where the “160-plus across the year” headline comes from. So in a single sitting, the two panels are close to even, both north of 100 markers. Function’s edge is the extra labs you pick up at the second visit, not a single mega-panel that doubles Superpower.

The honest nuance most listicles skip: past the core panels, more markers is not automatically more insight. The markers that move the needle for a healthy adult, metabolic, lipid, thyroid, inflammation, liver, kidney, and key vitamins, are covered well by both. Function’s additional markers earn their keep if you are managing something specific or you genuinely want the most complete snapshot available. For a clean yearly baseline, Superpower’s 100-plus already answers the questions most people actually have.

Clinician review: who looks at your results

This is Function Health’s clearest structural advantage, and the draft we are replacing undersold it. With Function, once all your results are in, a clinician reviews them and writes a summary to put the numbers in context, typically within one to two weeks. Out-of-range results get notes, and a genuinely critical value triggers a provider phone call. That written clinician layer is baked into the $365.

Superpower comes at the “who looks at this” problem from a different angle. Instead of a written clinician narrative on every report, it gives you a 24/7 human care team you can reach plus an AI concierge that walks you through what a flagged marker tends to mean and what to ask about. It is more interactive and always-on, but it is not the same as a clinician composing a written interpretation of your specific panel. If a human-written summary on your results matters to you, Function has the edge. If you would rather ask questions in real time and get guided scores, Superpower fits better. Neither is a substitute for your own doctor.

Cadence: one draw vs a structured two

Superpower is built around one comprehensive annual draw inside a continuous membership; if you want to recheck sooner, a follow-up panel is an add-on. Function bakes the rhythm in: an annual draw plus a roughly six-month retest, so you see movement across the year by default rather than choosing to pay for it.

That built-in retest is a real Function advantage if you are actively changing things, a new training block, a medication, a diet overhaul, a supplement stack you want to validate. Watching a marker shift at the six-month mark beats 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 if something looks off. The question underneath this whole comparison: are you optimizing in real time, or watching the long arc? The first case wants two draws. The second is well served by one.

Dashboard and trending

Both turn raw values into something readable, and this is where Superpower quietly pulls ahead for everyday use. Beyond the numbers it gives you 17 plain-language health scores and a personalized action plan, so instead of a wall of flags you get a few concrete next steps and a score you can watch over time. Function’s dashboard trends your results cleanly and pairs them with the clinician’s written notes plus food and supplement guidance, which is arguably more clinical but leans on you to act on the narrative. If a score-first, “tell me what to do next” interface is what gets you to actually use your results, Superpower’s presentation is the more action-oriented of the two.

Price and price-per-insight

This is the cleanest difference in the comparison. Superpower is $199 a year. Function is $365 a year, after a price cut from its earlier $499. That is roughly an 83 percent premium for Function, and you should know what it buys: the second draw and the written clinician review. If those two things matter to you, the premium is defensible. If they do not, Superpower delivers the insight most people act on at well under half the price.

One pricing caveat on Superpower: in New York and New Jersey the membership is $399 instead of $199, driven by state lab rules rather than a hidden upsell. If you live in either state, the cost advantage narrows sharply and you should weigh the two more evenly on features. For everyone else, $199 is the number that makes a yearly full-body draw feel routine instead of indulgent, and that low entry point is the single biggest reason most first-time testers should start here.

Collection: where and how you get drawn

Both run real venous draws through Quest, not finger-prick kits, which is the right call for an accurate full panel. Superpower gives you 3,000-plus Quest locations or, if you would rather not leave home, a mobile phlebotomist for roughly $119 extra. Function is built around a Quest lab visit, with in-home draws available as a paid upgrade depending on your situation. For most people this is a wash, you book a Quest slot and go. The tiebreaker only matters if at-home collection is important to you, where Superpower makes it a clearly priced option.

Availability, HSA/FSA, and your data

Both memberships are generally HSA/FSA eligible, and both provide receipts, though as always reimbursement depends on your specific plan and is never guaranteed. On data, both let you own and export your results, and Function lets you delete your data permanently at any time (with the obvious caveat that deletion cannot be undone). Availability has loosened compared to the early hype-driven waitlists; referral links to skip any queue are common for both. Net: on the housekeeping criteria, these two are close to even.

Superpower in depth

Superpower’s whole design philosophy is “low friction, high guidance.” You pay $199, book a draw at one of 3,000-plus Quest locations (or pay roughly $119 for a phlebotomist to come to you), and in about a week you get back 100-plus biomarkers spanning heart and vascular health, metabolic markers, lipids, thyroid, inflammation, liver, kidney, sex hormones, nutrient status, immune markers, and more, with calculated ratios layered on top.

What sets it apart is not the panel, it is what happens after. You get 17 plain-language health scores, a personalized action plan that points at a handful of concrete next steps, and a 24/7 care team plus an AI concierge you can interrogate about your specific numbers. That last layer is the difference between staring at a flagged value and Googling at midnight versus asking a contextual follow-up and getting a useful answer. The membership is HSA/FSA eligible. The recurring criticism is fair to name: $199 a year is still a subscription, the AI concierge is guidance and not a diagnosis, and if you want a written clinician narrative on every report, that is more Function’s model than Superpower’s.

Function Health in depth

Function Health’s design philosophy is “structured breadth with a clinician in the loop.” For $365 a year (down from its original $499), you get an annual draw of 100-plus biomarkers and a mid-year retest of roughly 60-plus more, both through Quest, which is where the marketed “160-plus across the year” figure comes from. After each round, a clinician reviews your results and writes a summary to give the numbers context, usually within one to two weeks, with notes on anything out of range and a phone call if something is critical.

The dashboard trends your markers over time and pairs them with food and supplement guidance, and you can retest individual markers on demand for an added member cost. The membership is HSA/FSA eligible, and you own your data with the ability to delete it permanently. The honest trade-offs: it costs noticeably more than Superpower, the second draw is a commitment, and the value of the extra mid-year markers depends on whether you will actually act on them. If a written clinician summary and a built-in twice-a-year rhythm are what you want, that is exactly what the higher price pays for.

Which biomarkers do they actually test, and why those matter

Both panels run well past 100 markers, so listing every one is noise. What matters is understanding the markers that actually change decisions. Here are the high-signal ones both services cover, in plain language, and why a healthy adult should care about each.

• ApoB (apolipoprotein B). A direct count of the cholesterol-carrying particles that drive plaque, and a better predictor of cardiovascular risk than standard LDL cholesterol alone. If one number on your panel deserves your attention, many clinicians argue it is this one.
• Lp(a) (lipoprotein little-a). A largely genetic, lifelong risk factor for heart disease that a standard physical almost never checks. You typically only need to measure it once, and knowing it early can reshape how aggressively you manage everything else.
• Fasting insulin. Rises years before fasting glucose does, so it can flag insulin resistance and metabolic trouble long before you would ever be called “pre-diabetic.” It is one of the earliest warning lights on the dashboard.
• HbA1c (glycated hemoglobin). Your average blood sugar over roughly three months, which smooths out the noise of a single fasting reading and tracks long-term metabolic control.
• hs-CRP (high-sensitivity C-reactive protein). A marker of low-grade, chronic inflammation linked to cardiovascular and metabolic risk. Useful as a general “is something smoldering” signal.
• Thyroid panel (TSH, free T4, often free T3). Governs energy, metabolism, weight, and mood. Subtle thyroid issues are common, easy to miss, and very treatable once you see them.
• Sex hormones (testosterone, estradiol, and related markers). Drivers of energy, libido, body composition, and mood for both men and women, and a frequent blind spot in standard checkups.
• Vitamin D. Widely deficient, especially in anyone who works indoors or lives at higher latitudes, with downstream effects on bone, immune, and mood health. One of the most common fixable flags.
• Ferritin (iron stores). Catches both iron deficiency (a common, fatigue-driving problem, especially in menstruating women) and iron overload at the other extreme. A small number with a big quality-of-life footprint.
• Liver and kidney panels (ALT, AST, creatinine, eGFR). The quiet organs. Both can drift out of range without symptoms, and catching that early is exactly the kind of thing a yearly baseline is for.

The takeaway: both Superpower and Function cover this entire high-signal set. Function adds more markers around the edges, but for the questions that actually change behavior, blood sugar, heart risk, inflammation, thyroid, hormones, key vitamins, organ function, the two are close. That is why the choice comes down to cadence, clinician review, and price rather than “which one tests the thing I need.”

Who should choose Superpower vs Function

Concrete personas, because “it depends” is useless advice.

• First-time tester, wants a yearly baseline, hates wasting money. Superpower. $199, clear scores, an action plan, and a concierge to ask questions. The friction is low enough that you will actually do it again next year.
• Actively changing things and wants to see results mid-year. Function. The built-in six-month retest is exactly the feedback loop you want when validating a new training block, medication, or supplement stack.
• Wants a human clinician to write up their results. Function. The written clinician summary and critical-result call are part of the model, not an add-on.
• Lives in New York or New Jersey. Re-run the math. Superpower is $399 there, so the price gap with Function’s $365 narrows or flips. Decide on features, especially whether you value the second draw and the clinician write-up.
• Data maximalist who will actually use every marker. Function, for the wider total across two draws. If you would never look at the extra labs, you are paying for a longer list you will ignore, and Superpower is the smarter buy.
• Wants the simplest possible “set a baseline, get told what to do” experience. Superpower. The score-first dashboard and action plan are the most action-oriented of the two.

Are full-body tests worth it? An honest take

We would be doing you a disservice if we only sold the upside, so here is the criticism, straight.

Incidental findings are real. Test 100-plus markers on a healthy person and you will almost always find something mildly out of range. Most of those flags are benign or transient. The risk is a cascade of follow-up tests, costs, and worry chasing a number that never mattered. A wide panel is a feature and a liability in the same breath.

Anxiety is a side effect. For some people, a dashboard full of yellow and red flags is genuinely stressful, and stress is not a health-neutral state. If you know you spiral over a single out-of-range value with no context, the guided, score-first framing (Superpower) or the written clinician summary (Function) matters more for you than the raw marker count.

Neither is a doctor. This bears repeating because the polished apps can make it feel like a diagnosis. They are not. A single out-of-range marker is a flag to investigate, not a verdict. Anything tied to your heart, kidneys, liver, or blood sugar should go to a licensed clinician before you act on it or change a medication. Nothing here is medical advice.

So are they worth it? For the health-conscious adult who will use the data, work with a clinician on anything concerning, and treat the dashboard as the start of a conversation rather than the end of one, yes. The structured early-warning system earns its keep. For someone who will spiral over benign flags or treat a flagged value as a self-diagnosis, the honest answer is to either skip it or lean hard on the guided/clinician layers. The tool is only as good as how you use it.

Frequently asked questions

Is Superpower or Function Health cheaper?

Superpower is cheaper at $199 per year versus Function Health at $365 per year (Function recently cut its price from $499). 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.

Does Function Health really test more biomarkers than Superpower?

Across the year, yes, but the gap is smaller than the marketing implies. Function tests 100-plus markers at the annual draw and roughly 60-plus more at the mid-year retest, which is where its “160-plus across the year” figure comes from. Superpower tests 100-plus in a single annual draw plus calculated ratios. In one sitting, the two panels are close. Both cover the high-signal markers a healthy adult cares about.

How accurate are the results?

Both services run real venous blood draws processed through Quest, a major accredited reference lab, not finger-prick home kits. That is the same lab infrastructure your doctor’s office uses, so the lab values themselves are reliable. Accuracy questions usually come down to interpretation, not the numbers, which is why both services layer scores, notes, or clinician review on top.

Are Superpower and Function Health HSA/FSA eligible?

Both are generally HSA/FSA eligible and provide receipts to support reimbursement claims. Eligibility ultimately depends on your specific plan and administrator, and neither company can guarantee reimbursement, so confirm with your plan before assuming the membership is covered.

Do I still need a doctor if I use one of these?

Yes. Both are screening and tracking services, not clinics. Function includes a written clinician summary of your results, and Superpower offers a 24/7 care team and AI concierge, but neither replaces your own physician. Use the results to have a smarter, data-backed conversation with a licensed clinician, especially for anything out of range.

How often should I test?

For most people building a baseline, once a year is enough, which is Superpower’s default rhythm. If you are actively changing your training, diet, medication, or supplements and want to see whether it is working, a twice-a-year cadence makes more sense, which is exactly what Function bakes in with its annual draw plus mid-year retest.

Can either one replace my annual physical?

No. A full-body blood panel is a powerful complement to a physical, not a substitute. A physical also covers a physical exam, blood pressure, vitals, screenings, and a clinician’s hands-on judgment that no blood panel captures. The best use is to bring your Superpower or Function results to your physical so your doctor has structured data to work from.

Where do I get my blood drawn?

Both use Quest. Superpower gives you 3,000-plus Quest locations or a mobile phlebotomist who comes to you for roughly $119 extra. Function is built around a Quest lab visit, with in-home collection available as a paid upgrade. Both are standard venous draws, so expect a quick appointment and results in roughly a week to two weeks.

Who owns my health data?

You do. Both services let you access and export your results, and Function explicitly lets you permanently delete your data at any time (with the caveat that deletion cannot be undone). As with any health platform, read the current privacy policy before you sign up if data handling is a priority for you.

Which should I choose if I am testing for the first time?

For most first-timers, start with Superpower: $199, plain-language health scores, an action plan, and a concierge to help you make sense of results. Step up to Function if you specifically want a built-in twice-a-year cadence and a written clinician summary out of the gate, and you are comfortable with the higher price.
