Libby vs. Superpower: Where Your Annual Panel Should Live for Life

Superpower is a longevity membership built around a big annual blood panel — well over 100 biomarkers a year, plus an in-app score, AI chat, and action plans. Libby isn't a membership and doesn't draw blood. It's the lifelong record your Superpower panel (and every other lab) can live in, on one timeline you own and can feed to any AI or clinician. So a "Superpower alternative" is usually not a different membership at all — it's a durable, cross-source home for the results, which complements the annual test rather than replacing it.

This is a fair look at where each fits. Superpower is a genuinely useful way to get a broad panel once a year with a guided first read. The question its own members ask most is the one a once-a-year membership doesn't fully solve — where do these 100+ markers live between tests, and how do I read them next to every other lab I've ever taken?

What's a good alternative to Superpower?

It depends which part you're trying to replace:

• If you want a different way to get tested — a different panel, price, or cadence — then the alternatives are other testing memberships, and that's a different article.
• If you want somewhere to keep and track the results over time — across Superpower, your doctor's draws, old labs, and whatever you test next — then what you want isn't another membership. It's a record you own that holds all of it on one timeline, for years.

Most people typing "Superpower alternative" want the second one. So the honest framing is: Libby is a complement to a big-panel membership, not a swap for the blood draw.

What Superpower does well

Credit where it's due. As of this writing, Superpower's pitch is an accessibly priced annual membership (around $199/yr — check their site, pricing changes) with a large panel of 100+ biomarkers, an in-app health score, and an AI chat with action plans layered on top.¹ (Verify their current panel size and features on their own site.) A broad annual panel surfaces markers most people never get tested — like Lp(a) or ApoB — that genuinely matter for long-term risk², and a guided first look lowers the barrier to getting started. For breadth-plus-guidance in one yearly step, that's a real service.

Where the model has a natural limit is time and ownership. A membership is built around this year's panel and its own dashboard. The questions that pay off most — which of my markers are trending the wrong way, and what changed? — need a record that spans years and survives whether or not you keep paying, and that can hold labs the membership didn't run.

The real question: where do your results live?

Say you run a Superpower panel this year, and a great one. Two years from now you want to know whether your ApoB is drifting, whether that HbA1c nudge held, whether the Lp(a) you finally measured is worth acting on, whether your vitamin D climbed after you started supplementing. To answer any of it, your Superpower results have to sit next to your earlier labs, your doctor's draws, and whatever you test later — lined up on one axis.

That's the crux, because the signal in lab work is the trend, not a single reading. A panel you can't compare to your history is a snapshot. And if results — plus the score built on them — live only inside one membership's app, they're one cancellation away from being hard to reach. Owning a copy is what turns a great annual panel into a decade of signal.

Superpower vs. a record you own

They're different categories, so a fair comparison is about role, not "better":

Read that as "these do different things," not "one wins." Many people keep a testing membership and a record they own — the membership tests and scores, the record remembers across every source.

What to do with your Superpower results

Concretely, once your panel is back:

1. Read it as a starting line, not a verdict. A first big panel is a baseline; the value compounds when you can compare the next one to it.
2. Get a copy out. Download or export your Superpower results as a PDF so you have them independent of the membership. (Doing the same for Quest and LabCorp pulls your whole picture together.)
3. Put them on a timeline you own. Import the panel into a record so each marker joins one axis with your other labs.
4. Ask better questions. With your history in a structured form, you can hand it to ChatGPT or Claude or bring a clean summary to a clinician — and reason about your trend, not a generic range.

Where Libby fits

Libby is the record for step three. Drop in your Superpower PDF and it reads every marker, reconciles the units, and files each one onto a single timeline alongside your Quest, LabCorp, Function, or hospital results — so a 100-marker annual panel stops being a one-time readout and becomes part of a history you can track. Libby imports lab PDFs from Quest, LabCorp, Function, BostonHeart, and Epic/Cerner systems; it's your data, exportable anytime, and ready to share with an AI or a clinician. It also computes a biological age (PhenoAge)³ from the relevant markers, which a broad panel is well-suited to feed. Superpower has its own in-app score, so think of Libby as the neutral, cross-source complement — the exportable record that holds your Superpower panel and every past lab, even if you leave.

That's the same role Libby plays for a Function panel, a SiPhox at-home test, an InsideTracker report, or the labs you're weighing whether Apple Health should hold.

If you've got a Superpower panel and want it to last longer than the membership, start your record and import it — the first upload takes about a minute, and there's a 14-day trial ($250/yr or $29/mo).

FAQ

What's a good alternative to Superpower? It depends what you want. For a different way to get tested, look at other testing memberships. For somewhere to keep and track your results over time — across every lab — you want a record you own, which complements a membership rather than replacing the annual panel.

Where can I keep my Superpower results long-term? Export your panel as a PDF and import it into a record you own. In Libby it joins one timeline with your other labs, so you keep it (and can read the trend) whether or not you renew.

Can I combine my Superpower results with my Quest and LabCorp labs? Yes — Libby consolidates results across providers onto one timeline, reconciling different units and marker names so everything lines up.

Is Libby a testing membership like Superpower? No. Libby doesn't draw blood or sell panels. It's the record your labs live in — you bring results from Superpower, Quest, LabCorp, Function, or your doctor, and it tracks them over years and makes them usable with an AI or a clinician.
