Function Health vs Superpower (2026): two $365 lab memberships compared
Last updated September 3, 2026.
The short version: remarkably similar offers at the same price point. Function Health lists $365 per year for 160+ lab tests with twice-yearly testing and clinician review. Superpower lists $349 to $365 per year for 150+ biomarkers across a baseline plus retest, at 2,000+ draw locations or at-home. This is as close to a genuine tie on structure as this category gets, so the differences are in the details.
Price: Function is $365 per year flat, framed as $1 a day, HSA/FSA eligible. Superpower's baseline membership lists at $365 per year with periodic promotions (a recent one at $349, plus $50-off-first-year offers), framed as $0.82 a day, HSA/FSA eligible. Winner on price: Superpower, slightly, when promotions apply; identical at list.
Testing scope: Function advertises 160+ lab tests annually across two testing rounds. Superpower advertises 150+ biomarkers across baseline plus retest, two blood draws a year, at 2,000+ locations or at-home draws. Winner on raw count: Function, marginally. Winner on draw convenience: Superpower's at-home option.
Interpretation: Both pair results with clinician or doctor-reviewed insights and AI-supported plans. Superpower leans harder into the AI-plus-human coaching framing; Function leans into research-grade breadth and tracking over time. Winner: tie, genuinely, on the published evidence.
Verdict: Best for maximum biomarker count and a research-forward framing: Function Health. Best for at-home draws and a coaching-forward experience at a slightly better promo price: Superpower. Either way, ask your actual doctor which of these panels would change your care; Pymander's free consult can help you think through whether membership testing fits your situation.

Common questions
Are Function Health and Superpower basically the same thing?
Structurally, yes: annual membership, 150 to 160+ biomarkers, two testing rounds per year, thousands of draw locations, AI plus clinician interpretation, HSA/FSA eligible, $365 list price. The real differences are marginal: Function lists more tests, Superpower offers at-home draws and runs promotions below list. Choosing between them on specs alone is splitting hairs.
Which has more biomarkers?
Function advertises 160+ lab tests annually; Superpower advertises 150+ biomarkers across the baseline and retest. Raw count favors Function slightly, though overlapping panels cover the same core systems (thyroid, cardiovascular, metabolic, liver, kidney, hormones, inflammation, vitamins).
Is $365 a year for lab tests worth it?
It depends on what you do with the results. Both companies argue early detection saves thousands (Function cites treatment costs like $12,022 per year for diabetes out of pocket). The skeptical view: many included tests would not change management for a healthy person, and your doctor can order targeted labs, sometimes covered by insurance. The memberships make most sense for data-motivated people who will act on trends.
Do I need a doctor's order for either?
No. Both are direct-access lab testing models that include the ordering clinician within the membership, bypassing the insurance and referral path. That is the core pitch of both.
Can I use HSA or FSA money for these?
Both state HSA/FSA eligibility on their pricing pages. Keep the itemized receipt; plan administrators occasionally query lab-testing memberships, and eligibility rules are set by your plan.
