Function Health vs Superpower (2026): Which Blood Test Is Worth It?

Per draw, they cost about the same. Function works out at about $183 a draw. Superpower works out at $199 on its one-draw offer and about $175 on its two-draw offer. So do not choose on price per draw. Superpower is the smaller annual bill, by $16 to $166 depending on the offer.

Function always tests twice. Its $365 covers 100+ tests at the annual visit and a follow-up of 60+ three to six months later, so you see what changed without paying again. Clinicians review every result, and a healthcare provider calls you if a result is critical. Superpower includes one draw or two, depending on the offer running when you join, so check before you assume.

Superpower does more after the results. Its membership opens a marketplace of supplements, prescriptions, peptides and add-on tests, with an AI assistant and a care team to ask. Function's add-ons are more testing: MRI, CT and cancer screening.

That last point is the honest tension. Superpower recommending a supplement it also sells is convenient and conflicted at the same time. How much that bothers you, and how many draws you want in the price, is most of this decision.

Function Health and OneTwenty were checked on their own websites on November 11, 2026. Superpower's column gives both offers its site has listed during 2026. "None listed" means the pages we checked on the company's own site do not offer it.

Function's price is one number. Superpower's depends on the offer, so both are shown. Divide each by what it includes.

Read down the per-draw and per-test columns and the answer is the same under either Superpower offer: these two cost about the same for what they test. What the offer changes is the size of the purchase. On the one-draw offer, Superpower is a $199 baseline and no more. On the two-draw offer it matches Function on frequency for $16 less.

So the question to ask of the price is not which one is cheaper. It is how many draws you want this year, and which Superpower offer is running the day you join.

Superpower also runs seasonal bundles and sign-up offers, such as a complimentary follow-up test for new members on the one-draw offer. They come and go faster than the membership does, so they are left out of these sums.

OneTwenty's number is different in kind. $499 covers four draws, one full panel and three targeted follow-ups, so the roughly $125 a draw is not like for like with a full panel. What it buys is more chances a year to see whether a change worked.

Function Health was founded in 2022, and Dr. Mark Hyman, a leading voice in functional medicine, is its Chief Medical Officer. The pitch is early detection: monitor the markers a routine physical skips, before symptoms show up. Our Function Health review goes deeper on the platform itself.

• 160+ lab tests a year across two draws: 100+ at the annual visit, then a Mid-Year Test of 60+ three to six months later. The Mid-Year Test must be used before renewal and does not roll over.
• Quest Diagnostics handles the draws at 2,000+ locations in 48 states, or you can schedule a draw at your home or office. The first results typically start arriving within 48 hours of testing.
• Clinicians review every result and flag issues. Each result comes with an explanation, action items and a clinician's summary.
• A healthcare provider calls you right away if any result is critical. We did not find an equivalent described on Superpower's site.
• Private AI Chat, plus the option to connect your results to ChatGPT, Claude or Perplexity. Supported wearable apps can be connected too.
• Add-ons are more testing: an annual MRI at $999 for members, CT scans and the Galleri multi-cancer test.

Function's limit is what happens after the results. It explains what is off, suggests what to do, and hands the problem back to you. Its pricing page and FAQ list no supplement store and no prescriptions. That is changing at the edges. SuppCo, a supplement recommendation service, is now part of Function, which says it will connect your supplement routine to your biomarker data. We found no supplements for sale on Function's own pages.

Superpower launched in 2023 out of Los Angeles as the cheap entry point to comprehensive testing. Its price and its plan have moved since, and during 2026 it has been $199 a year with one draw and $349 a year with two. Whichever offer is running, it is a broad lab panel for a flat annual fee, with more app around the results than the price suggests. Our Superpower review goes deeper on the platform itself.

These screens were captured in September 2026.

• One or two blood draws a year, depending on the offer: 100+ biomarkers on the one-draw offer, and 150+ across the year on the two-draw offer. Results are typically ready in about a week.
• Extra tests cost extra. On the one-draw offer, new members have been able to claim a complimentary follow-up test three to six months after the first draw. Anything beyond what the offer includes is an added charge.
• A biological age and health scores, with an action plan after every test.
• An AI assistant that answers from your own results, with a care team of clinicians behind it.
• Wearable syncing with Oura, Whoop and Apple Health, and uploads of past lab results so your history sits in one place.
• A marketplace of supplements, prescriptions, peptides and add-on tests for gut health, toxins and cancer screening, each billed on top of the membership.

The thing to watch on Superpower is the gap between the membership and the bill. The membership fee buys the testing and the platform. The supplements it recommends, the prescriptions it offers and the add-on panels in its marketplace are all separate charges, and the app is designed to lead you toward them. That is not dishonest. It is a different business model from Function's, and it is worth knowing which one you are buying into.

Whichever Superpower offer is running, the same four differences are left.

• How many draws are in the price. Function always includes two. Superpower includes one or two, depending on the offer.
• What happens when a marker is off. Function explains it and suggests what to do. Superpower explains it, can sell you the supplement and offers a route to a prescription.
• Who is reading your results. At Function, clinicians review every result and a provider calls if one is critical. Superpower leans on its AI assistant, with a care team behind it for anything that needs medical judgment.
• Whether the advice comes with a store. Superpower sells the supplements it recommends. Function's own pages list no store, though it now owns SuppCo, a supplement recommendation service. Convenience and conflict arrive together, and Superpower has more of both.

OneTwenty

A broad baseline, then retesting every 90 days

Our Recommended Alternative

Membership

$499/yr

$749 in NY & NJ

Lab panels

4/yr included

Draws a year

1 full + 3 targeted

Superpower tests once or twice a year and Function twice. The open question for both is whether that is enough readings to tell you anything. Change something in January, test in June, and you have one comparison a year to work from. OneTwenty is built around retesting: a full baseline of 101 lab markers, then three follow-up panels of 20 to 40 markers across the year, chosen from what came back off or what you are trying to change. That is four draws for $499, with a health coach, 22 device metrics tracked daily in between, and prescriptions through independent licensed providers when one is appropriate. Medications and custom supplement packs are add-ons, billed separately. It is available in every state except Rhode Island, at $749 a year in New York and New Jersey.

It is the most expensive of the three. If one broad panel is all you want, Superpower costs less under either offer. If you want two draws and a clinician reviewing every result, that is Function.

Four draws, not one or two

One full panel and three targeted follow-ups are in the membership, so a change you make in January is measured in April.

The retests are in the price

Superpower and Function each include at most one follow-up a year. OneTwenty includes three.

Follow-ups chosen from your results

Each follow-up tests 20 to 40 markers picked from what was off, not the same fixed list every time.

Data between the draws

22 device metrics tracked daily sit beside your labs, so the plan can move before the next panel.

Inside the OneTwenty dashboard

OneTwenty’s member dashboard puts your labs, your devices and your next step on one screen. Your latest device readings run along the top of every page (heart rate variability, blood pressure, sleep and sleep stages), beside your lab schedule and overall health score.

• Your markers in one read. The biomarkers page opens with a plain-English summary of how many results are optimal, which are out of range and which to focus on first, then scores each body system, from heart and vascular health to hormones and micronutrients.
• Every result on one chart. Open any marker and its full history sits on a single timeline, older lab reports you upload included, with the optimal range, the change since your last draw and a short note on what the marker means.
• An assistant that answers with your data. Ask a question from any page and it replies with your own charts, such as a month of sleep set against a month of steps, and explains how the two connect.
• Booking built in. When a draw is due, the dashboard counts down the days left to book, lists nearby lab locations with open times and maps the route.

Peptides at OneTwenty

Peptides are short chains of amino acids, the building blocks of proteins, and several are prescribed as treatments. The GLP-1 medications semaglutide and tirzepatide are peptides. OneTwenty’s catalog also carries the ones below, each physician-prescribed and prepared by a licensed U.S. compounding pharmacy, and only after an independent licensed provider has reviewed your labs.

• Sermorelin. A growth hormone releasing hormone analogue that prompts the pituitary to release more of your own growth hormone rather than replacing it. OneTwenty offers it for lean muscle, recovery and sleep.
• PT-141 (bremelanotide). Acts on melanocortin receptors in the brain and is prescribed for low sexual desire and arousal.
• GHK-Cu. A copper peptide in a cream, applied to the skin for appearance and repair.
• Oxytocin nasal spray. A peptide hormone involved in bonding and social connection. Research on it for social anxiety is mixed, so it belongs alongside anxiety treatment, not in place of it.

Every peptide runs on the same loop as the rest of the membership. Your labs set the baseline, your device data fills the gaps between draws, and the markers tied to the medication are rechecked at your quarterly labs before any larger dose change. Nothing changes without your prescriber, and you are not charged until a clinician approves the treatment. Compounded medications are not FDA-approved, which means the FDA does not review them for safety or effectiveness before they reach you, so ask your provider what the evidence shows for anything you start.

• How many draws do you want this year? Function includes two. Superpower includes one or two, depending on the offer, so read its site before you assume.
• Do you want the platform to act, or to advise? Superpower sells supplements and offers prescriptions. Function explains and suggests.
• Do you want supplement advice from someone who sells supplements? There is no right answer, but decide it deliberately and not by accident.
• Do you live in New York or New Jersey? Both cost more there. Superpower has listed $399 on its one-draw offer and Function publishes no figure. Get the real quoted price for both before comparing.
• How will you know if it worked? Two draws a year is one comparison a year, and one draw is none. If that is not enough, neither of these is the answer.

Both earn 4 out of 5. Set aside whichever offer Superpower is running and the two are closer than their prices suggest: a broad panel at a Quest lab, a dashboard with a biological age on it, and about the same cost per draw.

What separates them is steadier than the price. Function is a diagnostic with a clinician attached: two draws every year, 160+ lab tests, every result reviewed, and a call if one is critical. Superpower is a health platform with a diagnostic inside it: one or two draws depending on the offer, then a marketplace that sells the supplement and offers the prescription. Pick on how many draws you want and on whose incentives you are comfortable with, and read Superpower's offer on the day you buy.

Both share the same ceiling. At most two draws a year give you one comparison a year, which is enough to spot a problem and not enough to manage one. That is the case for testing more often. OneTwenty includes a 101-marker baseline and three targeted follow-ups at $499, four draws against one or two here. If you want your health followed across the year and not checked once or twice, that is the one we would look at first.
