Function Health starts at $365/yr. If you want more frequent retesting, a lower price, or a service that can treat what your results show, these are the alternatives worth comparing.
OneTwenty is the closest like-for-like alternative to Function Health built around retesting. Instead of two draws a year, its $499 membership includes four lab panels a year: a 101-marker baseline, then a follow-up panel every 90 days, so you can see whether what you changed is working. Custom supplement packs (from $45/mo) and prescriptions, including peptides, GLP-1s and testosterone, are priced on its site and run from the same results.

Function Health alternatives: FAQ
What is the best alternative to Function Health?
OneTwenty is the closest like-for-like alternative to Function Health built around retesting. Instead of two draws a year, its $499 membership includes four lab panels a year: a 101-marker baseline, then a follow-up panel every 90 days, so you can see whether what you changed is working. Custom supplement packs (from $45/mo) and prescriptions, including peptides, GLP-1s and testosterone, are priced on its site and run from the same results. Other strong options: InsideTracker (10.0/10, from $489 first year), Quest Health (9.9/10, from $199 one-time), Superpower (9.6/10, from $199/yr).
Is there a cheaper alternative to Function Health?
Rythm Health starts at $79/month; SiPhox Health starts at $124 per at-home test kit; Quest Health starts at $199 one-time, against $365/yr for Function Health. Compare what each price includes: number of draws per year, at-home collection fees and follow-up tests change the real annual cost.
Which Function Health alternative tests most often?
Rythm Health and SiPhox Health send at-home kits as often as monthly, but each kit tests a smaller set of markers. For full blood panels, OneTwenty and Lifeforce both retest every 90 days; OneTwenty starts from a larger 101-marker baseline (Lifeforce lists 50+ markers per draw).
Which Function Health alternatives can prescribe treatment?
OneTwenty, Superpower, Lifeforce can prescribe after testing. Function Health is testing only.
