Why people start hunting for Function Health competitors
Function Health put whole-body lab testing on the map, and that is exactly why so many people end up searching for a Function Health competitor. The platform is genuinely good, but at $365 per year it is not the cheapest door into the category, and it is built around a heavier two-draws-per-year cadence that not everyone needs.
The honest framing: this is not about finding a Function Health competitor that beats it on every line. It is about matching the service to your actual goal. Want a simple annual baseline you can track over time? Want maximum clinical depth? Want to check one specific marker this week? Those are three different products. Below we compare the field so you can pick on purpose, not on hype.
The Function Health competitors landscape at a glance
There are dozens of testing brands now, but for a buyer comparing against Function Health, four names do most of the work. Here is the plain-English version of where each one lands.
Superpower: best overall value and the one we recommend
Superpower is a membership that costs $199 per year and includes one comprehensive annual blood draw covering 100+ biomarkers (about 150 once you count calculated ratios). You get 17 plain-language health scores, a personalized action plan, and an AI concierge you can actually chat with about your results. In New York and New Jersey the price is $399 because of state lab rules.
The reason it tops this list of Function Health competitors is simple: it delivers a comparable full-body picture for roughly half the annual cost, and it translates the numbers into something a non-doctor can act on. It is a screening and tracking service, not a diagnostic clinic, so think of it as your yearly health dashboard rather than a replacement for care.
Function Health: the most clinically thorough, at a higher price
Function Health runs $365 per year and tests 160+ biomarkers, with two draws per year plus a urinalysis and a 6-month retest. That cadence is its real differentiator: you get a second look built into the membership, which is appealing if you are actively changing something and want to confirm it moved. Its AI chat layer is newer than some rivals but improving.
If your priority is sheer marker count and a clinician-grade depth of panel, Function Health earns its price. The trade-off is cost and a heavier commitment than a once-a-year user needs.
Everlywell: best for one or two targeted markers
Everlywell is a different shape entirely. It sells at-home, single-marker test kits at per-kit pricing, processed through CLIA-certified labs with results delivered online. You are not buying a 150-marker baseline here; you are buying a thyroid panel, or a vitamin D check, or a specific hormone test, one at a time.
That makes Everlywell the smart pick when you already know what you want to look at and a full membership would be overkill. It is less a Function Health competitor and more a complement: use it to spot-check a single number between annual baselines.
SiPhox Health: best for finger-prick convenience
SiPhox Health offers at-home blood testing with a finger-prick option and longevity-focused panels. If the venous blood draw is the thing stopping you, SiPhox removes that friction by letting you collect a sample yourself. Its panels lean toward the longevity and optimization crowd. The convenience is real; just weigh the breadth of any given panel against what an in-person draw captures.
Function Health competitor pricing: what you actually pay
Pricing is where the Function Health vs alternatives question gets decided for most buyers, so here are the verified numbers side by side. Superpower is $199 per year ($399 in NY and NJ). Function Health is $365 per year. Everlywell is per-kit, so your cost depends entirely on which test you buy and how many. SiPhox prices by panel; check the provider for current pricing before you commit.
The takeaway: if you want the widest annual panel for the lowest predictable yearly cost, Superpower is the value leader. If you only need a single marker, a one-off Everlywell kit will almost always be cheaper than any membership. Anything in between is a judgment call about how much depth you truly use.
How to choose the right Function Health competitor for you
Skip the spec-sheet paralysis and answer three questions.
First, what is the job? A broad annual baseline points you to Superpower or Function Health. A single targeted marker points you to Everlywell. Second, how much depth do you actually act on? Most people do not change behavior off 160 markers; they act on a dozen. The 17 plain-language scores in Superpower exist precisely because raw marker dumps overwhelm people. Third, what is your budget tolerance? At $199 versus $365, Superpower leaves real money on the table for the same yearly-checkup job, while Function Health buys you a second draw and a higher marker count if you genuinely need them.
The pattern across these services is consistent: score-based tools win on clarity and a ready-made action plan, while single kits win when you only have one question to answer. Choose the shape that fits your question.
When a single-kit option fits better
If you are not ready for a full membership and just want to check one thing, an at-home single-marker kit is the honest answer, not a yearly plan you will underuse.
Our pick among Function Health competitors
For the everyday goal of one comprehensive blood baseline you can track year over year, Superpower is the best-value Function Health competitor in 2026. It pairs a 100+ biomarker panel with scores and an AI concierge that turn data into next steps, at $199 per year instead of $365. Function Health remains the depth champion if you want 160+ markers and two draws, and that is a fair reason to pay more. But for most readers, the value math favors Superpower.
One safety note that applies to every service here: these are screening and tracking tools, not diagnoses. Any result outside the normal range should be reviewed with a clinician before you act on it.
Full-body lab membership: 100+ biomarkers, doctor-reviewed, tracked over time.

Superpower is the best-value full-panel membership at $199 per year, Everlywell wins for single-marker at-home kits, and SiPhox is built for finger-prick convenience. The right Function Health competitor depends on whether you want a broad baseline or one targeted test.
Is there a cheaper Function Health competitor that still tests a lot of markers?
Yes. Superpower covers 100+ biomarkers (about 150 with calculated ratios) for $199 per year, compared with Function Health at $365 for 160+ markers. For a once-a-year baseline, Superpower is the cheaper Function Health competitor while still giving you a broad panel plus 17 plain-language scores and an action plan.
Function Health vs Superpower: which should I pick?
Pick Superpower if you want the best value for an annual full-body baseline, simple scores, and an AI concierge at $199. Pick Function Health if you want maximum depth, 160+ biomarkers, and two draws per year with a built-in 6-month retest at $365. The Function Health vs Superpower choice comes down to depth versus value.
Are these at-home blood tests a replacement for seeing a doctor?
No. Every service on this list, including each Function Health competitor, is a screening and tracking tool, not a diagnostic clinic. They help you spot trends and ask better questions, but any result outside the normal range should be reviewed with a clinician who can interpret it in the context of your full health picture.
Should I use Everlywell or a full membership?
Use Everlywell when you have one specific question, such as checking thyroid or vitamin D, since its per-kit pricing is cheaper than any yearly plan for a single marker. Choose a full membership like Superpower when you want a broad annual baseline you can track over time rather than a one-off test.
