Does Superpower cost less than Function Health?

Yes. Superpower costs $349 a year, while Function Health costs $365. Both prices include a built-in second round and a personalized protocol; Superpower's membership adds a member-priced supplement marketplace and prescription access.

How long do Function Health results take?

Function Health results arrive in stages: the first batch lands within about 48 hours, and the rest follow over the next few weeks as different assays from your annual draw process at different speeds. Superpower returns results in 5-10 business days from its initial draw.

Can I use an HSA/FSA for Superpower?

Yes. The $349 membership is HSA- and FSA-eligible, so pre-tax dollars can cover it.

Is Superpower worth it?

Members tend to think so once they use the plan, not just the panel. Superpower says 93% found their action plan more useful, even life-changing, than a yearly checkup. Two rounds of data matter less than a protocol you'll actually follow.

Superpower vs Function Health: Features & Pricing (2026)

Key takeaway:

Function Health and Superpower are both annual, membership-based biomarker testing services with a built-in second draw every year: Superpower runs ~90 biomarkers on its initial draw (150+ tests total once its built-in retest of ~60 of them is folded in), and Function Health runs ~100 biomarkers annually (160+ once its mid-year retest of ~60 of them is folded in). Both include a personalized action plan. However, if you want to act on that plan without leaving the membership, Superpower is $349/year and adds a member-priced supplement marketplace and prescription access, and 36.3% of Superpower members reduced their biological age score between their first and second year.

What is Superpower, and what is Function Health?

Superpower and Function Health are both biomarker testing companies. A biomarker testing company offers blood-based testing on a membership basis, measuring your biomarkers at set intervals. Biomarkers are measurable signals in your blood, things like cholesterol, blood sugar, and hormones.

Some platforms stop at data and a report. Others turn those results into a plan you can actually follow. Two questions separate them: how much do they measure, and what do they help you do next?

Superpower and Function Health both answer the first question with a wide annual panel, and the second with a personalized plan. Where they diverge is what happens after that plan lands.

What does Superpower include?

Superpower follows a simple path:

Join for $349 a year.
Give an initial blood draw at a lab, or at home for an added fee.
Receive ~90 health metrics in your dashboard.
Get a personalized action plan.
Message your care team on demand.
Take a built-in follow-up draw later in the year, repeating ~60 key trackable markers.

Both draws happen at any of 2,000+ partner locations across 40+ states, or at home for an added fee. Results land in your dashboard 5-10 business days after each one.

Among those results is a biological-age score, included in every membership. It's a single number for your whole body, so an optional OrganAge add-on breaks it into nine organ-level scores, across systems like metabolism, inflammation, liver, and kidney health, showing you which ones are pulling the total up or down.

Acting on any of it happens in the same place. A supplement marketplace carries member-exclusive pricing, and prescriptions run through that same marketplace when clinically appropriate, priced separately.

What does Function Health include?

Function Health uses a two-test model. Its annual test covers ~100 biomarkers, and a mid-year test then re-tests ~60 of them to see what's changed. Function markets the combined count as "160+ lab tests," though the mid-year round repeats markers rather than adding new ones.

That second draw is built into the $365 price, whether or not you want one. Clinicians review and flag your results, and a personalized protocol is built into the membership. Function also tracks a biological-age measure.

Testing happens at partner labs, or via a concierge at-home draw in select areas. Following its SuppCo acquisition, Function now matches your results to recommended supplements, but there's no member-priced supplement marketplace and no prescription access. The protocol tells you what to change; buying and filling it happens elsewhere.

What biomarkers do the Superpower and Function Health memberships measure in 2026?

Superpower's initial draw runs ~90 biomarkers, with 150+ tests total once its built-in retest of ~60 of them is folded in. Function Health's annual test covers ~100 biomarkers, marketed as "160+ lab tests" once its mid-year retest of ~60 of them is folded in. Both count on the same basis: an initial draw of roughly the same size, plus a retest of markers already on it, with direct lab measurements and calculated values counted together in each headline figure.

Both also cover the markers that matter most, including ApoB, Lp(a), and HbA1c. Here's how each headline number is built.

	Superpower	Function Health
Initial draw	~90 biomarkers	~100 biomarkers
Follow-up draw	Retests ~60 markers already on the initial panel	Retests ~60 markers already on the annual panel
Headline count	"150+ biomarkers" across both draws	"160+ lab tests" across both draws

What support and next steps do Superpower and Function Health offer?

Superpower includes on-demand access to a care team you can message about your results, and it adds what Function doesn't. This is where the two diverge most.

Superpower: on-demand care team you message directly about your results, plus prescription access covering GLP-1 and TRT (medications priced separately) and a curated supplement marketplace with member-exclusive pricing.
Function Health: results explained by physicians and researchers, with member chat and the option to chat with an AI assistant on its website between draws, support Function says stops short of medical advice; it states that it does not offer medical treatment, and delivers personalized food and supplement guides rather than a member-priced marketplace, so Function points you elsewhere to act on parts of your data.

What are the official 2026 membership prices for Superpower and Function Health?

Superpower costs $349 a year, while Function Health costs $365 for one year, not the wide gap this comparison used to show. Both prices now include a built-in second round: Function's second draw repeats tests from its annual panel, published together as 160+ lab tests a year, while Superpower's second draw retests ~60 biomarkers. Neither is optional anymore, so a second round of testing isn't what separates them.

Both memberships turn results into a protocol. Superpower's $349 also includes the means to follow it: a member-priced supplement marketplace and prescription access. Both are HSA/FSA eligible, so pre-tax dollars can cover either one.

Who is Superpower best for, and who is Function Health best for?

Superpower is best for:

People who want to spend less.
People who want to act on the plan without leaving the membership.
People who want supplement and prescription access in one place.
People who value fast results.

Function Health is best for:

People who want a longer-established, dedicated biological-age product.
People comfortable acting on their results elsewhere.
People who prefer clinician-reviewed flags over messaging a care team directly.

Function Health vs Superpower: the bottom line

Neither company is short on data. Function Health tests ~100 biomarkers on its annual draw (160+ once its mid-year retest is folded in) and Superpower tests ~90 on its initial draw (150+ once its built-in retest of ~60 of them is folded in), on the same two-draw structure, and both track biological age, so the panel isn't where they part ways.

Function's model is testing, tracking, and a protocol: two rounds a year, clinician review, a large marketed panel, and a personalized plan, for $365. Superpower matches that structure at $349 and adds the means to follow the plan, a member-priced supplement marketplace and prescription access. A plan is standard for both; what differs is whether you can act on it without leaving the membership.

Superpower: a plan you can act on in one place

Function Health's two rounds of data, clinician notes, and personalized protocol tell you what changed and what to do about it, and recommended supplements come through its SuppCo partnership, but buying those supplements at member pricing, or filling a prescription, is still on you elsewhere.

Superpower closes that loop inside the same membership: your 150+ biomarkers become a personalized action plan, on-demand care-team messaging carries you between draws, and a supplement and prescription marketplace sits inside the $349 price instead of pointing you elsewhere.

Starting with a clearer picture of your own biology is the real first step, not just another data point. Start your Superpower membership and turn this year's blood draw into a plan you'll actually follow.

Frequently asked questions

Superpower runs 150+ tests across an initial ~90 biomarker draw plus a built-in follow-up draw that retests ~60 of the same markers, combining direct lab measurements with calculated values — not 150 distinct biomarkers. Function Health's annual test covers ~100 biomarkers; it advertises "160+ lab tests" a year, but that figure folds in a ~60 marker mid-year re-test of the same markers, not 160 distinct biomarkers either. Both count on the same basis, and both second draws repeat a similar number of markers, so the two headline figures are closer than the gap between them suggests.

It depends on what you want. Both include two testing rounds a year, a personalized protocol, and a biological-age measure, and Function's biological-age product is the longer-established one. Superpower adds on-demand care-team messaging, a member-priced supplement marketplace, and prescription access in the same membership. For most people who want to act on their results in one place, Superpower is the stronger fit.
