Superpower vs Function Health: two 100-biomarker memberships, one price rise
These two are the closest competitors in consumer biomarker testing, and one of them just changed its price. Which makes this a good moment to ask what you're buying beyond the blood draw.
Function Health wins on panel depth and retesting; Superpower wins on entry price — for now. Function covers 114 biomarkers across two panels a year for $365. Superpower launched at $199 a year for 100+ biomarkers, with that founding rate rising to $349 from 1 September 2026, and listing $399 for members in New York and New Jersey. Both flag far more results than a healthy person should expect.

The price is moving — check it before you buy
Superpower's $199 founding rate is listed as increasing to $349 a year from 1 September 2026, with $399 quoted for members in New York and New Jersey. Function Health sits at $365 a year, itself reduced from $499 earlier in 2026.
At $199, Superpower was the obvious value pick. At $349 against Function's $365, the comparison changes completely: for $16 more you get 114 markers twice a year instead of 100+ once. On cost per result that's roughly $1.60 versus $3.49.
This is exactly why we date-stamp every price we publish. If you're reading this months from now, verify both before acting on the comparison.
The retest is the underrated feature
Function's second annual panel isn't a bonus — it's the thing that makes a flagged result interpretable. A single out-of-range value on a large panel is usually noise; the same value twice is a signal. Building the confirmatory test into the membership is genuinely good design, and it's the strongest argument for Function at near-identical pricing.
Both will flag results you don't need to worry about
A laboratory reference range is defined as the central 95% of a healthy population, so each marker carries a 5% chance of falling outside it in a perfectly healthy person. Across 114 markers the probability of at least one out-of-range result is about 99.7%, with roughly six flags expected. Across 100 markers it's about 99.4%, with five expected.
Real biomarkers correlate within panels, so the true figures are somewhat lower — but the direction holds, and neither company puts this on the results screen. It is one paragraph of copy that would make both products meaningfully safer, and we've now asked for it in two comparisons.

Priya's take
Co-founder & Head of TestingI've now written this argument twice and I'll keep writing it until someone ships the fix. These are competent products running standard assays through real laboratories, and their weakest component is the screen where they hand you the results.
On the choice itself: at Superpower's founding $199 it was the easy recommendation, and a lot of the coverage you'll find online was written at that price and hasn't been updated. At $349 — $399 if you're in New York or New Jersey — Function's $365 for double the panels is better value, and the included retest is the feature that actually helps you act on a flag.
What I'd do with either: buy one panel, once, in a year when you have a reason. Take the results to a clinician who knows your history. Don't subscribe indefinitely — repeated broad screening on an asymptomatic person mostly generates follow-up testing you didn't need.
And check today's price on both sites before you decide. The most useful thing in this comparison may be the reminder that the numbers moved.
Who should choose which
Choose Function Health if…
- You want the deepest panel available
- The included mid-year retest matters to you
- You want clinician-reviewed results as standard
- You're in NY or NJ, where Superpower costs more
Choose Superpower if…
- You can still get the founding rate
- You only want one panel a year
- The entry price is the deciding factor
Choose neither if…
- You're anxious about health — this category reliably makes that worse
- You have symptoms; see a clinician who can order the right tests
- Your insurance already covers the panel your doctor would choose
Superpower is the better pick if you can still access the founding $199 rate, or if you genuinely only want a single annual panel and the entry price decides it.
Not medical advice. Nothing here diagnoses, treats or replaces a clinician who knows your history. Results and symptom records are a starting point for a conversation, not a substitute for one.
Frequently asked questions
Is Superpower or Function Health better value?
At Superpower's new $349 rate, Function Health at $365 is better value — 114 biomarkers across two panels a year versus 100+ across one, roughly $1.60 per result against $3.49. At Superpower's original $199 founding price, Superpower was the cheaper entry point.
How much does Superpower cost in 2026?
It launched at a $199 founding annual rate, rising to $349 from 1 September 2026, with $399 listed for members in New York and New Jersey. Verify the current price before purchase.
Why do so many biomarkers come back abnormal?
Because a reference range is the central 95% of a healthy population, giving each marker a 5% chance of falling outside it by chance. Across 114 markers the probability of at least one flag is about 99.7%, with roughly six expected.
Should I subscribe year after year?
Only with a reason — a treated deficiency you're rechecking, a medication change, a specific clinical question. Repeated broad screening in someone without symptoms mainly produces follow-up testing and anxiety.
