For most people, Superpower is the best lab test membership for longevity tracking if you want the best value and a strong baseline panel; Function Health is the better pick if you want the most comprehensive annual testing and can pay more.[6][7]
- Best overall value: Superpower — cited as the lowest-cost starting point at $199/year, with 100+ biomarkers, a biological age estimate, and historical lab upload.[6][7]
- Most comprehensive mainstream membership: Function Health — cited as covering 160+ lab tests with testing 2x/year, aimed at broader ongoing tracking.[7][8]
- Best integrated longevity platform: InsideTracker — described as an excellent starting point and “the most integrated platform” for longevity-specific blood analysis, with structured tracking and personalized recommendations.[1][2]
If your goal is specifically longevity tracking rather than just “more labs,” the most useful markers are usually the ones that change risk and are easy to act on: ApoB, Lp(a) once, hs-CRP, and HbA1c.[3] That is why a cheaper membership that reliably surfaces those markers can be a better buy than a larger but less actionable panel.[3]
A practical recommendation by buyer type:
- Choose Superpower if you want the best entry price and a solid longevity baseline.[6][7]
- Choose Function Health if you want more biomarkers and twice-yearly monitoring.[7][8]
- Choose InsideTracker if you want a more guided, integrated experience with recommendations.[1][2]
If you want, I can also rank these by price, biomarker count, clinician oversight, and ease of use in a simple comparison table.
