Quick answer: In a Superpower blood test vs Function Health matchup, the winner depends on how much data you actually want. Superpower covers 100+ biomarkers (about 150 counting calculated ratios) in one annual draw for $199 a year, with 17 plain-language health scores, a personalized action plan, and an AI concierge. Function Health is the heavier instrument: 160+ biomarkers, a baseline draw plus a follow-up retest (Function markets it as roughly twice-yearly testing) and typically a urinalysis, for $365. For most healthy adults building a yearly baseline, Superpower is the better value and the one we recommend. Choose Function only if you want maximum marker coverage and a built-in retest checkpoint.

Superpower Blood Test vs Function Health: The Short Version

These two services get lumped together because they look alike from a distance: both are direct-to-consumer membership programs that order a wide blood panel, run it through accredited labs, and hand you a slick dashboard instead of a stack of lab printouts. That is where the similarity ends.

The real difference is philosophy. Superpower is built around one comprehensive annual snapshot you can read and act on without a medical degree. Function Health is built around clinical depth: more markers, more frequent retesting, more raw data to sift. One is a clean yearly baseline; the other is a closer-to-clinical workup. Neither is wrong. They are aimed at different buyers.

If you remember one thing from this superpower health vs function health comparison, make it this: pay for the depth you will actually use. Most people do not retest 160 markers twice a year and act on every one. They want a clear picture once a year and a plan. That is Superpower’s whole pitch.

Panel-by-Panel: What Each One Actually Tests

This is where the superpower function health debate gets decided, so let us be specific about the panels rather than waving at “100 plus” versus “160 plus.”

Superpower’s panel

Superpower runs 100+ biomarkers per draw, roughly 150 once you count calculated ratios (things like LDL particle ratios or kidney function estimates that are derived, not separately drawn). The panel spans the major systems a smart annual physical would want and then some: metabolic and blood sugar, a full lipid profile, liver and kidney function, thyroid, key hormones, inflammation markers, and a complete blood count. On top of the raw numbers, you get 17 health scores that roll those markers into plain-language categories so you are not staring at 150 rows trying to guess what matters.

The honest framing: this is broad enough to catch the things that quietly drift off-range for years (blood sugar creeping up, lipids worsening, thyroid sliding) which is exactly what an annual baseline is for.

Function Health’s panel

Function Health pushes wider: 160+ biomarkers, and critically, a baseline draw plus a scheduled follow-up retest, with a urinalysis typically included. Function markets this as roughly twice-yearly testing. That extra 60-or-so markers and the urine component mean Function reaches into territory Superpower’s single annual blood draw does not, and the retest gives you a second data point within the same membership year.

If your goal is the most exhaustive snapshot a consumer service will sell you, Function is the more clinically thorough product. We are not going to pretend otherwise. The question is whether that extra breadth changes what you actually do, and for most healthy people, it does not.

Draws, Retests, and Cadence

This is the most underrated line in any superpower blood test vs function health comparison, because it quietly drives both the price and the experience.

Superpower gives you one comprehensive blood draw per year. One appointment, one wide snapshot, one plan. For someone who wants a yearly checkpoint and intends to repeat it next year to watch trends, that rhythm is plenty.

Function gives you a baseline draw plus a follow-up retest, marketed as roughly twice-yearly testing, with a urinalysis typically included. If you are actively changing something (a new diet, a supplement protocol, training for an event) and you want to see the needle move at the retest instead of waiting a full year, that cadence is a genuine advantage. You pay for it, but it is real.

So the cadence question reduces to: are you tracking a baseline (Superpower) or running a half-year experiment on yourself (Function)?

Clinician Review and the AI Layer

Neither service is a clinic, and that matters for how you read your results. Both are screening and tracking tools, not diagnostic providers. Any result that lands outside the normal range should be reviewed with a licensed clinician before you act on it. Treat both dashboards as a starting point for a conversation, not the conversation itself.

On the software side, Superpower’s AI concierge is a notable strength: you can chat with it about your results in context, ask what a marker means, and get plain-English answers tied to your own numbers. Function has been rolling out its own AI chat, but it is newer than Superpower’s. If a friendly, mature “explain my results to me” layer matters to you, Superpower currently has the edge there.

The 17 health scores reinforce that edge. Function hands you more raw markers; Superpower does more of the interpretation for you. Whether that is a feature or a limitation depends on whether you enjoy reading lab data or just want to know what to do about it.

Price: The $199 vs $365 Question

Here is the math that ends most superpower health vs function health arguments.

Superpower is $199 per year for 100+ biomarkers, the 17 scores, the action plan, and the AI concierge. One caveat worth flagging up front: pricing has been reported as higher in a few states with stricter lab rules (New York and New Jersey have come up), so if you live there, confirm the current price at checkout before you compare, rather than assuming the headline $199.

Function Health is $365 per year for 160+ biomarkers, with a baseline draw plus a follow-up retest and a urinalysis typically included. So you are paying roughly 1.8 times as much for about 60% more markers and a built-in retest.

On pure cost-per-marker, the two are closer than the sticker prices suggest, because Function tests more. But cost-per-marker is the wrong metric for most buyers. The right question is cost-per-decision: how many of those markers will actually change what you do? For a healthy adult, Superpower’s narrower-but-readable panel at $199 usually delivers more decisions per dollar. For a data maximalist, Function’s depth justifies the premium.

Which One Should You Pick?

Skip the hand-waving. Here is the straight call for the superpower function health decision.

Pick Superpower if you are: a generally healthy adult who wants one broad, readable annual baseline; someone tired of getting 5 to 10 markers at a standard physical; a person who values 17 plain-language scores and a plan over 160 raw numbers; or anyone optimizing for value at $199 a year.

Pick Function Health if you are: a data maximalist who genuinely wants 160+ biomarkers; someone actively changing their health who needs a follow-up retest to see progress; a person who wants a second checkpoint and a urinalysis in one membership year; or someone for whom maximum coverage beats price.

For the broad middle of the market, healthy people who want clarity once a year, Superpower is our recommended pick. It wins on value and readability, and the single annual draw is enough for what most people will act on.

Our Verdict

In the superpower blood test vs function health head-to-head, both are legitimate, well-run services, and you will not get burned by either. Function Health is the more clinically thorough product: more markers, a baseline draw plus a follow-up retest, and a urinalysis, for $365. Superpower is the better value and the easier to actually use: 100+ biomarkers, 17 health scores, a plan, and a mature AI concierge for $199 (a bit higher in a few states with stricter lab rules, so confirm at checkout).

Our recommendation for most readers is Superpower, on the simple logic that the best blood test is the one whose results you understand and act on. Function earns the nod only when you specifically want maximum depth and twice-yearly tracking. Buy the depth you will use, not the depth that looks impressive on a feature chart.

Is Superpower or Function Health cheaper?

Superpower is cheaper at $199 per year (a bit higher in a few states with stricter lab rules, so confirm at checkout) versus $365 for Function Health. Function costs more because it includes more markers, a baseline draw plus a follow-up retest, and a urinalysis. For one readable annual baseline, Superpower is the value pick.

Superpower health vs Function Health: which has better result reviews?

Both give you a dashboard, not a doctor. Superpower leans harder into interpretation with 17 plain-language health scores and a more mature AI concierge, so results feel easier to read. Function gives you more raw markers to dig through. Either way, review out-of-range results with a clinician.

Do I need a retest like Function Health offers?
