Superpower vs Function Health vs Hundred
These are the three services people actually weigh against each other, and most pages comparing them are written by someone paid by one side. So is this one. Here's the disclosure first, the numbers second, and the part where I tell you to pick a different one third.
| Category | Superpower | Function Health | Hundred |
|---|---|---|---|
| Sticker price Superpower and Hundred's base tier list at the same $199. Superpower and Function Health both charge more in New York and New Jersey without publishing the figure — Superpower's NY/NJ price is consistently reported as $399; Function Health's FAQ confirms a surcharge without naming an amount. Check the number at your own checkout. | $199/year | $365/year | $199 or $499/year |
| Price with my code superpower20 takes a flat $20 off Superpower. I have no code for Function Health or Hundred and earn nothing if you join either. | $179/year | $365/year | $199/year |
| Lab tests included Function Health's advantage, and it's real: 100+ at the annual visit, then 60+ more at a mid-year follow-up. Hundred states "100+ lab tests included with your annual membership" and does not break it down further. | 100+ per year | 160+ per year | 100+ per year |
| Blood draws per year Two draws means you see whether a change you made actually moved a marker, without waiting a full year. Hundred doesn't publish its draw schedule, and secondary sources contradict each other on it, so this row stays blank rather than guessing. | 1 | 2 | Not published |
| Cost per test, per year Crude but the only apples-to-apples ratio available, and it assumes each service's own "100+" or "160+" claim at face value. Superpower is cheaper per marker than Function Health; against Hundred's base tier it's a wash before my code and cheaper after it. | $1.79 | $2.28 | $1.99 |
| Where the draw happens All three use Quest, so the draw itself is the same chair and the same phlebotomist. Hundred also uses BioReference and advertises the widest location network. Not a differentiator worth deciding on. | Quest Diagnostics, 3,000+ sites | Quest Diagnostics, 2,000+ sites | Quest Diagnostics and BioReference, 5,000+ sites |
| Imaging (MRI / CT) Function Health sells scans alongside the membership. None of the three includes imaging in the base price. | Not offered | Paid add-on | Not published |
| Insurance All three are cash-pay and all three are HSA/FSA eligible with an itemized receipt. | Not accepted | Not accepted | Not accepted |
| Fasting required Same practical advice regardless: book the earliest morning slot you can get. | From the night before | 8 hours | Not published |
Figures verified (Superpower), (Function Health) and (Hundred), each read off that company's own site. "Not published" means the company does not state it publicly — not that the answer is no.
Where Function Health is genuinely better
Two things, and neither is close. They test more markers — 160+ a year against Superpower's 100+. And they test you twice, with a mid-year follow-up panel of 60+ markers. That second draw is the one I'd miss. If you find something out of range in January, Superpower has you waiting until next January to see whether anything you did about it worked. Function has you back in the chair in a few months.
If your reason for testing is to change something and then check your work, the extra draw is worth more than the price gap. I'd rather say that plainly than pretend the cheaper option wins on every axis.
Where Hundred complicates things
Honestly? Hundred's base tier is the same $199 as Superpower's, for a comparable "100+ lab tests" claim. On sticker price alone there is nothing between them, and I would be selling you something if I pretended otherwise on a page where I earn a commission from one side.
What separates them at that price is harder to pin down, because Hundred publishes so little. I can't tell you how often they draw your blood, what their fasting protocol is, or what happens to the price in New York — none of which is stated on their site. The two things I can say: they advertise the largest lab network of the three (5,000+ sites, Quest plus BioReference), and their pitch is built around a 100-day protocol rather than an annual snapshot, which is a genuinely different product shape.
If a same-price alternative with a coaching-style protocol appeals to you more than an annual baseline, Hundred deserves a look, and my code doesn't change that arithmetic. What it does change is the Superpower side: $179 against their $199.
Where Superpower is better
Price, and not marginally: $179 against $365 with my code. That's roughly half, and it holds per marker too — $1.79 per test against $2.28. For a first comprehensive baseline, you're paying about half as much to find out most of the same things.
The app is the other one, though here I'm comparing something I use daily against something I've only read about, so weigh it accordingly. What I can say is what my review says: the interpretation layer is the actual product, and Superpower's is the most comprehensive I've used. Every marker sits against its range with a plain-language status, there's a Superpower Score and a biological-age estimate, and the panel covers the categories that matter for a baseline.
So which one should you pick?
Pick Superpower if this is your first comprehensive panel, you want an annual baseline you'll actually look at, and the difference between $179 and $365 is a real consideration. That's most people asking this question, which is the honest reason this site exists rather than a marketing one.
Pick Function Health if you're actively working on something — a marker you already know is off, a protocol you're mid-way through — and the mid-year re-test is the point rather than a bonus. Also pick them if you want the extra ~60 markers and the imaging add-ons under one roof, and the price gap doesn't decide it for you.
Look at Hundred if the 100-day protocol framing appeals more than an annual baseline, or if their 5,000+-site network is the difference between a draw down the road and a draw across town. Go in knowing you'll have to ask them directly for the details they don't publish — start with how many draws a year $199 actually buys.
Whichever you land on, all three draw your blood at Quest, none takes insurance, and all three are HSA/FSA eligible — which is worth more than any discount code, mine included. Take the earliest morning appointment you can get and eat nothing after dinner the night before.
What I can't tell you
I can't tell you what Function Health's app feels like on the twelfth time you open it, or whether their clinician notes are useful or boilerplate, or how any of these results land against each other on the same body in the same week. Nobody who hasn't paid for all three can, and plenty of pages comparing them will tell you anyway.
For Hundred the list is longer, and it's their choice rather than my omission: how many draws a year the membership includes, what the fasting window is, whether New York and New Jersey pay more. Every one of those is a normal thing to publish, and every one of them is a question you'd have to ask them before paying. The marker lists are the exception: those are published, and lining them up marker by marker is the one part of this comparison nobody has to take on trust.
What I can tell you is the part I did: the draw, the seven vials, the week of results rolling in, and what $179 actually buys. If that's the one you land on, the code is below.
