Superpower Health Review: Is the $499 100-Lab Membership Worth It?

The one-sentence version

Superpower is a well-marketed, well-priced direct-to-consumer (DTC) lab membership that does one thing genuinely well — it surfaces a big baseline panel, including a handful of cheap, outcome-validated markers your annual physical usually skips — and one thing it cannot do at all: actually treat you. The product is real and the price is competitive, but the "100+ biomarkers + a longevity dashboard" framing oversells what a tube of blood buys. It is structurally test-but-don't-treat, the long marker list is padded with correlated and vanity numbers, and the bigger story around the company — the well-publicized 2025 lawsuit between Function Health and Superpower over a former employee and trade-secret claims — is a business dispute, not a signal of clinical quality either way. Whether ~$499/year is worth it depends entirely on whether you will act on the few markers that matter. For where lab memberships sit in the field, start with our pillar on longevity medicine: what's proven vs hyped and our breakdown of what longevity biomarker panels actually test.

What Superpower actually is

Superpower is a venture-backed DTC lab-testing startup (it raised a widely reported ~$30M round) that sells an annual membership — positioned around $499/year, though DTC lab pricing shifts constantly, so treat that as current market info. For the fee you get a large baseline blood panel headlined as "100+ biomarkers," a follow-up retest within the year, a polished app that flags results outside "optimal" ranges, and physician-ordered labs so a clinician signs off on the order. The pitch is concierge-grade data at a consumer price — and on price-per-marker, that part is broadly true.

What you do not get is treatment. Superpower surfaces and tracks numbers; it is not a clinic that prescribes, titrates, and manages therapy. That testing-versus-treating split is the structural catch of the entire DTC lab band, and it is the single most important thing to understand before paying. We map the whole band in longevity clinics vs lab memberships.

The good: it surfaces the markers a basic checkup skips

The honest case for Superpower is the same as for any well-built lab membership: a standard annual physical often orders a basic lipid panel, a metabolic panel, and a CBC, then stops. A big DTC panel routinely includes several markers with strong hard-outcome evidence that your checkup probably doesn't:

• •ApoB counts the number of atherogenic particles, and when it disagrees with standard LDL cholesterol (common in metabolic syndrome) the particle count is the better predictor of cardiovascular events¹.
• •Lp(a) is a genetically set, mostly lifelong-stable particle that causally raises heart-attack and stroke risk — Mendelian-randomization data make that case cleanly². You measure it once; a high result reshapes how aggressively everything else gets managed.
• •hs-CRP, a marker of low-grade inflammation, predicted cardiovascular events at least as well as LDL cholesterol in a large prospective study³.
• •HbA1c predicted all-cause and cardiovascular mortality continuously in a population study — including below the diabetes threshold⁴.

If Superpower's panel gets these four numbers in front of a motivated person — plus catches a treatable thyroid, ferritin, or vitamin D problem people misattribute to "aging" — it has earned a real slice of its fee. That is the legitimate core, and on cost-per-marker Superpower is one of the cheaper ways to get it.

The catch: padding, and a "longevity" dashboard that tests without treating

Now the honest case against the framing. The "100+ biomarkers" headline does a lot of marketing work:

• •A large share is ordinary bloodwork — CBC, metabolic panel, standard lipids, thyroid, electrolytes — useful, but the same labs a primary-care order or a cheap requisition provides. Bundling them into a "100+" count makes the panel look more exotic than it is.
• •Much of the tail is correlated padding that tracks the cheap Tier-1 core, adding line items and a sense of completeness without much independent, actionable signal. More tubes of blood is not more health.
• •Some featured markers mislead as targets. IGF-1, marketed as a youth hormone, has a U-shaped mortality relationship — both low and high IGF-1 associate with higher mortality. And the two biggest longevity levers in all of epidemiology aren't on any blood panel at all: cardiorespiratory fitness, among the most powerful survival predictors ever measured⁵, and grip strength, which outpredicted blood pressure across 17 countries in the PURE study⁶.

The decisive limit is structural: Superpower is a measurement product. It flags that your ApoB is high or your HbA1c is creeping up — it does not then manage you. A dashboard full of green-and-amber flags can create a false sense that paying for the data is doing something. For a health-literate person who will take an abnormal result to a clinician, that's fine; for someone hoping the membership itself improves their health, it's a category error.

The Function Health lawsuit, in plain terms

Because it comes up in every "Superpower vs Function" search, it's worth stating cleanly: in 2025, Function Health sued Superpower in a dispute centered on a former Function employee and allegations involving confidential information / trade secrets. That is a business and personnel dispute between two competitors. It tells you the DTC-lab space is crowded and competitive; it does not tell you that either company's clinical product is better or worse. Don't let litigation headlines stand in for an evidence judgment about the panels themselves — for the rival product on the merits, see our Function Health review and the head-to-head Function Health vs Superpower.

The grade, and how we got there

Two axes, because conflating them is the trap:

• •As a cheap way to surface outcome-validated markers your checkup skips: moderate-to-strong. ApoB, Lp(a), hs-CRP, and HbA1c are real, hard-outcome-linked tests, and Superpower's price-per-marker is competitive.
• •As a "100+ biomarker longevity" upgrade that improves your health: weak. Roughly half is basic labs, much of the tail is correlated padding, a few markers (IGF-1) mislead as targets, and — decisively — it tests without treating.

That split lands the letter grade in the middle: a B for the actionable core and the price, a C for the "longevity dashboard" model most people think they're buying. If you're health-literate, have a clinician who'll act on the results, and value cheap convenient access to ApoB and Lp(a), it can be worth it. If you're hoping a subscription will make you healthier, the money does more in a targeted outcome-validated panel plus actually treating the few markers that matter. We run that whole cost-benefit in are longevity clinics worth it?.

Who should and shouldn't buy it

• •Reasonable buyer: a motivated, health-literate person who wants ApoB, Lp(a), hs-CRP, and HbA1c surfaced cheaply and will take abnormal results to a clinician who treats them.
• •Poor fit: someone expecting the membership to improve their health, or who'll read a long list of flags as a scoreboard. For most of that budget, a targeted panel plus treatment does the job — and if you mainly want a biological-age number, the open PhenoAge formula derives one from a basic blood draw for free, as we cover in free biological-age tests. Don't confuse a comprehensive blood panel with an epigenetic-age test — that's a different product with its own limits, graded in biological age tests.

Bottom line

Superpower's real value isn't the "100+ biomarkers" — it's the four or five cheap, outcome-validated markers (ApoB, Lp(a) once, hs-CRP, HbA1c) it surfaces at a competitive price, plus the occasional treatable deficiency catch. The rest is largely ordinary bloodwork dressed up by a big number, a correlated tail that adds little independent signal, and the occasional vanity marker. Most important, it tests without treating: it flags problems it won't fix, and the Function Health lawsuit is a business story, not a clinical verdict. Worth it for a motivated buyer with a clinician who'll act on the results — a poor fit for anyone hoping a subscription is itself a health intervention.
