Superpower and Function Health are two of the best-known lab membership services, and they are often compared directly. Both bundle blood testing into a yearly membership, but they differ in price, how much testing is included and how results are delivered. FitScript publishes this page and is shown alongside them as a third option built around reading the labs you already have.
FitScript publishes this comparison and is one of the services compared. Competitor facts come from each company's own website as of October 15, 2026. Prices and features change, so check their current terms before you decide.

The main differences are price and how much testing each membership includes. Superpower lists membership from $199 per year with 100+ biomarkers from one blood draw. Function lists $365 per year with 160+ lab tests a year, split between a 100+ test annual visit and a 60+ test mid-year retest.
So Superpower has the lower published entry price, while Function includes a second round of testing within the year. Which matters more depends on whether you want to see change across the year or mainly want one broad baseline.
Superpower's $199 yearly membership, which it expresses as $0.55 a day, includes one comprehensive blood test a year across 100+ biomarkers, a biological age with 17 health scores, a personalised protocol after every test, the Kin AI and 24/7 access to a care team. It also lists access to add-on tests such as gut, toxin and Galleri screening, plus supplements, peptides and prescriptions.
Function's $365 yearly membership, which it expresses as $1 a day, includes 160+ lab tests a year across an Annual Test and a Mid-Year Test, explanations written by doctors, clinician review of every result, a personalised protocol and member pricing on MRI and CT. Function states that membership renews at the then-current price, and it provides an itemised receipt for HSA or FSA claims.
Both note that New York and New Jersey can differ. Superpower says pricing may vary for members there, and Function says testing there can cost more because of state regulations. Superpower states that members can cancel anytime and keep access through the end of the paid year, and Function states that members can cancel and rejoin at any time.
Superpower publishes its menu in groups, including 19 hormone and thyroid markers, 41 heart and metabolic markers and 10 cancer and other risk markers such as PSA, hs-CRP and homocysteine. It adds energy markers such as ferritin and iron saturation, DNA health markers such as B12, folate and methylmalonic acid, and aging scores. One comprehensive test is included each year, and follow-up tests can be added at any time.
Function publishes a longer menu that includes ApoB, lipoprotein(a), LDL particle number and size, omega-3 and omega-6 levels, heavy metals, autoimmunity markers, AMH and PSA, with many markers marked as tested twice a year. The 60+ biomarker Mid-Year Test must be used before the annual renewal.
So the core trade is breadth and frequency against price. Function lists more tests and a second draw. Superpower lists the lower price and leaves follow-up testing to each member's choice.
Both use Quest. Superpower lists 2,000+ Quest locations, or at-home testing in most major US metros for an additional fee, and Function lists 2,000+ Quest labs in 48 states with an at-home draw option. Function notes it is not yet available in Rhode Island, Hawaii or Puerto Rico.
On timing, Superpower states results in 10 days or less, typically in about a week, while Function states that first results typically arrive within 48 hours of testing. Both describe a personalised plan built from the results.
Superpower delivers results to its app, with a dashboard of what is working, what needs attention and where to focus. Its protocol covers diet, lifestyle and supplements, with follow-up timelines, and Superpower says it updates as results change, with clinicians reviewing the decisions that matter.
Function delivers results with explanations written by doctors, action items and a clinician's full summary. A healthcare provider calls if a result is critical, and members can download a PDF to share with their own doctor.
Function also publishes its preparation guidance. Members fast for 8 hours, avoid seafood for 48 hours before heavy metal tests, and some members need two visits, for example to time hormone tests within a menstrual cycle.
On published prices, a year of Superpower is $199 with one comprehensive test included, and a year of Function is $365 with an annual test and a mid-year retest included. At-home draws with Superpower carry an additional fee, and members in New York and New Jersey may see different prices with both, so the figure you pay can be higher than the headline.
Add-ons change the total too. Superpower lists add-on tests such as gut, toxin and Galleri screening, and Function lists member pricing on imaging, including the Annual MRI at $999. If you expect to add tests or scans, price them in from each company's own pages.
With FitScript, twelve months of Protocol is $240 before any lab panels, and panels run from $49 to $499, so the yearly total depends on how many panels you order. Peak is $99 per month or $999 per year and adds provider access and two group coaching calls a week.
Superpower lists an AI assistant called Kin alongside one-on-one support from clinicians, plus wearable connections and past-lab uploads. Function states that clinicians review every result, lets members connect AI partners such as ChatGPT, Claude and Perplexity, and offers an annual MRI to members for $999.
Both accept uploads of results from outside their own testing, which helps people keep older labs in one place.
Superpower states that member data is encrypted, stored in a HIPAA-compliant way and accessible to its clinical team, that members can export and delete it at any time, and that it is never sold or shared with insurers, advertisers or brokers.
Function states that only the member, its lab partners, clinicians and essential administrators can access results, with some results shared with state health authorities where the law requires it. Members who connect an AI partner can control, delete or disconnect that data.
FitScript describes its provider messaging as secure and HIPAA-compliant. Whichever you choose, read the privacy policy before uploading health records.
Superpower is a good fit for someone who wants a broad baseline at the lower published yearly price, with an AI assistant, a care team and access to add-on tests and follow-up in one membership.
Function is a good fit for someone who wants two large panels a year, clinician review of every result, faster first results and member access to MRI and CT.
FitScript suits people who already have labs from either one, or from their doctor, and want them read against optimal ranges with an AI they can question, adding panels one system at a time. Protocol includes a 7-day trial.
FitScript takes a different approach from both. Instead of bundling a yearly panel, it starts with labs you already have. The Protocol membership, at $20 per month including a 7-day trial, adds Atlas, the daily protocol and unlimited conversations about your results. When you want new testing, you choose a panel by system and pay for that panel.
Because FitScript reads uploaded reports from other providers, it can also sit alongside a Superpower or Function membership rather than replace it.
See FitScript pricing, FitScript Essential, Thyroid Complete
FitScript reads uploaded reports from Function Health, Lifeforce, Quest, Labcorp or a doctor, from PDFs, photos taken on a phone or hospital exports, and states that it reads a panel no matter who ordered it. Atlas has a read in under a minute. Each marker is scored against optimal ranges as well as the standard range, across up to 149 biomarkers, and the results feed a FitScore, a Bio Age and a Living Health Map.
Protocol at $20 per month then adds Atlas conversations and a full daily protocol, and Peak adds provider access and two group coaching calls a week. When you want fresh testing, single-system panels start at $49, so someone with a yearly membership elsewhere can fill a gap, for example with a thyroid or heart panel, between scheduled draws.
See Upload your labs, Cardiovascular Deep
Start with the tests you actually want. A large biomarker count is useful when it covers the systems you care about, such as thyroid, hormones, heart, liver and kidney health. Read each provider's published list and look for the specific markers you have been told to watch, for example ApoB, fasting insulin or free T3, rather than comparing totals alone.
Next, think about how often you will retest. Seeing a number move after three or six months is often more useful than a single snapshot, so include the cost of a second draw in any yearly total. Check where you can be drawn, how long results take and whether a clinician reviews anything outside the standard range.
Finally, look at what happens after the results arrive. Some people want a clear written plan, some want to ask questions about their own numbers, and some want a licensed provider involved. Membership terms, renewal pricing and HSA or FSA eligibility are worth reading closely too, since they change over time.
If the lowest published yearly price for a broad panel matters most, Superpower lists the lower figure. If you want two rounds of testing a year, faster first results and optional imaging, Function is built for that. If you already have labs and want them read against optimal ranges with an AI you can question, adding panels only when you need them, FitScript is built for that.
Prices and inclusions change, so confirm each company's current terms on its own site. A licensed clinician is the right person to interpret results that fall outside the standard range.
On published yearly price, yes. Superpower lists membership from $199 per year and Function lists $365 per year, as of October 2026. Function includes a mid-year retest, so compare what each includes as well as the price.
Both list Quest. Superpower lists 2,000+ Quest locations or at-home testing, and Function lists 2,000+ Quest labs in 48 states plus an at-home draw option.
Function states that first results typically arrive within 48 hours of testing. Superpower states results in 10 days or less, typically in about a week.
Yes. Superpower lists an at-home draw in most major US metros for an additional fee, and Function lists an at-home draw with a licensed specialist. Check each site for current availability and cost in your area.
Function offers MRI and CT at member pricing, including an Annual MRI at $999 for members. Superpower lists add-on tests such as gut, toxin and the Galleri cancer screen.
Yes. FitScript reads uploaded lab reports from other providers and scores them against optimal ranges. Protocol includes a 7-day trial.
Many people retest a panel after about three months to see whether changes in sleep, training or diet have moved the numbers, then every six to twelve months once results are steady. A clinician can suggest a schedule based on your own results.
No. FitScript publishes it and is one of the services compared. Every competitor fact links to that company's own site and shows the date we read it, so you can check anything that may have changed.
