Function Health is best for a dense annual biomarker baseline through a lab-location draw. Superpower is best for a broad consumer health platform — labs plus data upload, wearables, AI chat and care-team access. AMORTAL is neither: it takes whichever you choose and turns the results into one ranked next action, a watchlist, a clinician-ready question, and an outcome loop.
Function Health and Superpower are two of the most talked-about biomarker memberships — and they’re built on different bets. Function leans into a dense, clinician-reviewed annual panel drawn through a lab-location network. Superpower leans into a broad consumer health platform that folds labs together with data upload, wearable connections, an AI chat and care-team access.
Both answer “what do my numbers look like?” well, in their own way. Neither is built to answer the harder question that comes next: “so what should I actually change, what should I ignore, and when do I retest?” That’s the gap this page is about — and where AMORTAL fits, on top of whichever one you pick. It’s educational, not medical advice.
vs
+
Use Function or Superpower for the data. Use AMORTAL to decide what the data should change, what to ignore, what to watch, and when to retest.
The short version: who each is for
Two of these produce data in different shapes; the third decides what to do with whichever you have. Here’s the honest split.
Which one fits which job
Function HealthBest for a dense annual baselineA wide, clinician-reviewed biomarker panel run once or twice a year through a lab-location draw. Strongest when you want a dense snapshot and a structured report to react to.
SuperpowerBest for a broad health platformLabs bundled with external-data upload, wearable connections, a biological-age readout, protocols, an AI chat and care-team access. Strongest when you want an all-in-one consumer platform.
AMORTALBest for deciding what to do nextNot a lab. A longitudinal decision layer that reads whatever results you already have — from either provider — and returns one ranked next action, a watchlist, a clinician-ready question, and an outcome loop. Including when to do nothing.
This isn't an "A beats B." Function and Superpower answer what are my numbers in different shapes; AMORTAL answers what should they change. The strongest setup is one provider plus AMORTAL.
Function vs Superpower vs AMORTAL, at a glance
Tap between the three to see what each is actually responsible for.
What each one owns
Same goal — better decisions from your blood — split into two data shapes and one decision layer.
Function — the dense baseline
A broad annual biomarker membership: a wide panel (Function advertises 160+ lab tests annually), clinician-reviewed results, and action plans, with the draw done through a national lab-location network.
You want one dense, clinician-reviewed snapshot a year and a structured report to work from. Verify the current marker count, price and partner network before buying.
Superpower — the broad platform
A consumer health platform: biomarker testing (Superpower advertises 100+), external health-data upload, wearable connections, a biological-age readout, protocols, an AI chat, care-team access and add-on tests.
You want an all-in-one place that bundles labs with wearables, chat and a care team. Verify current claims, pricing and what's included before buying.
AMORTAL — the decision layer
Not a lab. It takes either provider's results, normalises them into a memory, and produces one ranked next action, a watchlist, a clinician-ready question, and an outcome loop — with restraint built in.
You already have results and the real question is "what now?" — what to change, what to ignore, what to watch, and when a retest is actually worth it.
AMORTAL has no direct integration with either — you bring the data in by upload or manual entry.

Which one fits what you actually want
| What you want | Reach for |
|---|---|
| The densest clinician-reviewed annual baseline | Function Health |
| An all-in-one platform with wearables, chat and a care team | Superpower |
| To upload my own external health data into one place | Superpower |
| I already have results — tell me what to do next | AMORTAL |
| An auditable decision, not a chat answer | AMORTAL |
| To know whether I should retest yet | AMORTAL |
| A clinician-ready question, not a treatment directive | AMORTAL |
| To track whether a protocol actually worked | AMORTAL |
| To avoid changing five things at once | AMORTAL |
| To connect a blood result to my wearable trends | AMORTAL (or Superpower for the upload) |
Where AMORTAL fits — whichever you pick
The model is the same regardless of which membership you choose: let the provider do the testing, then run the result through a decision process instead of a dashboard.
- Bring the result in. Upload your Function or Superpower report, or enter the key markers — there's no direct integration, so you carry the data over.
- Normalise into memory. AMORTAL files each biomarker into a longitudinal record, not a one-off screen.
- Connect the context. Results are linked to your goals, symptoms, wearables, medications and constraints.
- Activate the standards. The guidelines and decision rules that actually apply to your situation switch on.
- Produce a Decision Contract. One change at a time, with the expected signal and the window written down in advance.
- Rank one Next Best Action. Not ten. The single highest-value move — which may be "do nothing yet."
- Set the watchlist. Markers worth re-checking get an expected direction and a recheck window.
- Close the loop. When the next panel or outcome signal arrives, AMORTAL checks whether the action worked — and keeps or discards it.
A decision loop, end to end
Here’s the same flow on a single example — illustrative numbers only, not a target or a reference range.
From a result to a tracked outcome
Your Function or Superpower panel returns an elevated ApoB (say, in a range your clinician flags as worth attention). On a dashboard — or in a chat reply — that's a red number and a vague nudge.
AMORTAL files it next to your prior lipids, your goals, your medications and your wearable trends — read as a trajectory, not a single dot.
One lever, not five. The expected signal (ApoB direction) and the window to see it are written down before anything changes.
Framed as a clinician-ready question — "given this trend, is [one specific lever] the right first move?" — not a treatment directive AMORTAL has no authority to give.
The marker goes on watch with an expected direction and a recheck window — so you retest when it's informative, not on a guess or a renewal date.
At the next draw, AMORTAL checks: did it move as expected? If yes, the change earns its place. If not, it's dropped — no story told over noise.
AMORTAL doesn't diagnose and isn't a substitute for your clinician — anything urgent goes to a professional, now.
Function or Superpower — which fits you?
If you’re choosing between the two, this narrows it. Whichever you land on, AMORTAL sits on top of it.
Function, Superpower, or it doesn't matter?
What do you most want from the membership?
Which "more than labs" matters most to you?
A dense, clinician-reviewed annual baseline is Function's strength. Verify the current panel and price, get the draw, then bring the results into AMORTAL to rank what to actually do.
If you want labs bundled with wearables, upload and chat, Superpower's breadth fits. Verify what's included, then use AMORTAL to turn its data into one auditable, outcome-tracked decision instead of a chat answer.
If your real goal is acting on results, the provider matters less than what you do next. Pick on price and convenience, then let AMORTAL rank the next best action and tell you when to do nothing.
Where each is strongest — and where it isn’t
In fairness to all three:
- Function is strongest when you want a dense, clinician-reviewed annual baseline without assembling a panel yourself — and less ideal if your bottleneck is deciding on data you already have.
- Superpower is strongest when you want labs bundled with wearables, upload, chat and a care team in one platform — and less ideal if you’d rather not have your decisions anchored to one product’s ecosystem.
- Verify before you buy. Marker counts, prices, promotions and included features change for both — confirm the current details on each provider’s own pages.
- Breadth is a beginning, not an answer. Some results will need a clinician; AMORTAL should never be read as a diagnosis, whichever provider produced the number.
Bring your results into a decision, not a dashboard
AMORTAL doesn’t need to be where you buy your blood tests. The stronger model is to let a provider like Function or Superpower do the testing, then use AMORTAL as the longitudinal decision system around those results. Upload the report, or enter the markers that matter. AMORTAL turns the result into memory, evaluates what’s still missing, ranks the next best action, sets a watchlist for the signals to expect, and later checks whether the action actually worked.
Already have results from Function or Superpower? Bring them into AMORTAL and ask the only question that matters: “What should I do next?”

Frequently asked
Function Health vs Superpower — which should I choose?
It depends on what you want from the membership. Function is strongest as a dense, clinician-reviewed annual biomarker baseline drawn at a lab location. Superpower is strongest as a broad health platform that folds labs together with data upload, wearable connections, an AI chat and care-team access. Both publish their own marker counts and pricing, which change often — verify the current details before buying. Whichever you pick, AMORTAL works on top of the results.
Can AMORTAL work with results from either Function or Superpower?
Yes. AMORTAL is lab-agnostic and works from results you already have — you bring them in by uploading the report or entering key markers (there's no direct integration with either). It normalises the biomarkers into a longitudinal memory, connects them to your goals, wearables and protocols, and returns one ranked next action rather than another dashboard. The provider you chose stays your data source; AMORTAL is the decision layer.
Does AMORTAL replace Function Health or Superpower?
No. They do a different job. Function and Superpower produce and review biomarker data; AMORTAL decides what that data should change, what to ignore, what to watch, and when to retest. Most people who use AMORTAL keep their provider for the testing and use AMORTAL to turn each result into an auditable decision and an outcome loop.
Superpower has an AI chat — how is AMORTAL different?
An AI chat answers questions in the moment. AMORTAL produces a Decision Contract: it writes down one change, the single signal you'd expect it to move, and the window to watch — in advance — then checks later whether it actually worked. It's auditable and outcome-tracked rather than conversational, and it's deliberately built to recommend doing nothing when that's the right call.
Is a bigger biomarker panel always better?
Not automatically. Both providers advertise broad panels, and breadth is useful for a baseline — but more markers also mean more borderline results that tempt over-reaction. AMORTAL evaluates whether a marker actually changes a realistic decision, whether the result is timely, whether a clinician should weigh in, and what downstream signal to watch, so breadth becomes useful instead of noisy.
When should I retest after using Function or Superpower?
That depends on what you changed and how long it takes to show up in blood — not on the calendar or a membership renewal. AMORTAL sets an expected window per marker and tells you when a retest would be informative versus premature. Retesting too early is one of the most common ways people waste a panel and misread normal variation as a result.
