The ranking
People focused on nutrition and fitness optimization who want a periodic blood panel with algorithmic recommendations and no prescribing.
+First-year bundle price includes a blood test of up to 54 biomarkers
−Mobile draw ($119 extra) required for residents of NY, NJ, RI, AZ and HI
Cost-conscious adults wanting an annual baseline lab panel plus optional access to prescriptions through the same app, and who accept that medication prices are not published.
+Lowest published entry price of the three bloodwork services reviewed ($199/yr with one lab panel)
−Only one blood test per year included; follow-up testing costs extra
On record: Function Health filed a false-advertising suit in C.D. Cal. alleging Superpower's '100+ biomarkers' claim overstates ~55 direct lab measurements; outcome not confirmed by a reliable source.
Marek Health
7.1Data-driven clients who want extensive lab panels and coach-led, provider-supervised hormone optimization, and who will pay out of pocket without a clear upfront total.
+Named care team includes MDs and DOs (e.g. Medical Director Steven Campbell, MD) alongside DNPs, FNPs and a PA-C
−Lab panel is a separate purchase (minimum $450) and outside lab results are not accepted to start
People who mainly want frequent longevity lab testing and wearable data tracking, accept an upfront non-refundable annual fee, and treat prescriptions as an optional add-on.
+Four lab panels a year (101-marker baseline plus three follow-ups) are included in the membership price
−The annual membership is non-refundable after a 7-day window, and only if no service has started (3% fee applies)

Tools for this decision
How we ranked these
Same rubric, plus whether the service offers treatment or testing only, because those are different products. Facts come from each provider’s own pricing, FAQ and terms pages, with regulator and court records where they exist. Scores are produced by a fixed table, so the same facts always give the same score. See the rubric.
