Function Health vs Superpower: $365 vs $349 a year for lab testing

Last updated September 3, 2026.

Function Health and Superpower are the two biggest names in membership lab testing, and they are closer than their marketing suggests. Both charge a few hundred dollars a year for a large biomarker panel, doctor-reviewed results, and a dashboard. The differences are in panel size, price, and what wraps around the labs.

What does each one cost?

Function Health charges $365 per year, billed annually, which it frames as $1 per day and contrasts with a claimed $15,000 out-of-pocket equivalent. Superpower starts at $349 per year, with 150+ lab tests across two blood draws, and it contrasts that with a claimed $10,000 equivalent. Both run promotions; Superpower was advertising $50 off the first year at the time of writing. On sticker price, Superpower is $16 cheaper per year.

What do you actually get?

Function Health starts you with 160+ lab tests that it says detect signals across more than 1,000 conditions, with testing available at home or at more than 2,000 partner labs through Getlabs. Superpower members get 150+ lab tests across two blood draws per year, a baseline of 100+ biomarkers, wearable and lifestyle data integration, and a personalized protocol built with its medical advisory board; it also cites a member survey in which 60% said Superpower flagged something a doctor had previously missed. Function leans on panel size and scale. Superpower leans on the protocol and coaching layer.

Which one should you pick?

Both are cash-pay longevity services, and neither replaces a doctor. If you want the largest panel and do not care about extras, Function Health's 160+ tests at $365 is the bigger panel per dollar. If you want an action plan, wearable integration, and a slightly lower price, Superpower starts at $349. Either way, bring abnormal results to a clinician who knows you.

You said your annual labs flagged a cholesterol number you have not seen before. What was the actual value, and was this a fasting draw?

LDL came back 158, and yes, I fasted overnight. Last year it was 130. Nothing else was flagged.

Thanks for giving me all this information. Based on what you've said, one elevated LDL is a conversation, not a crisis, and I will walk you through what moves it and what to ask your doctor. Here's your care note to share with your care team.

Care note

Elevated LDL, follow-up plan

Fasting LDL 158, up from 130. Dietary changes, exercise, recheck per clinician. Chest pain or family history of early heart disease changes the urgency.
