Do Function Health and Hundred Health sell supplements?

They handle supplements differently. Function Health has brought SuppCo into the platform so you can connect your supplement routine to your biomarker data, described as guidance rather than a member-priced storefront. Hundred Health's membership includes discounts on supplements, through a marketplace that carries supplements only.

Are Function Health and Hundred Health HSA/FSA eligible?

Both list their memberships as eligible: Function Health as HSA/FSA eligible and Hundred Health as HSA/FSA eligible too. Eligibility still depends on your own plan, so check with your administrator before counting on pre-tax dollars.

Function Health vs Hundred Health: Features & Pricing (2026)

Key takeaway:

Function Health has brought supplement guidance inside the platform: SuppCo is now part of Function, so your supplement routine sits against your own biomarker data, in a $365/year membership with 160+ lab tests a year. Hundred Health instead gives members discounts through a supplements-only marketplace, at $16/month, billed annually at $199, for 100+ lab tests analyzed annually. However, if you want the year to include support between tests rather than a single scheduled read, Superpower is $349/year and pairs a personalized action plan — one 93% of members rated as more useful or even life-changing than their yearly checkup — with on-demand care-team messaging.

How do Function Health and Hundred Health compare?

The clearest line between these two runs through your supplement shelf. Function Health has brought SuppCo in-house, so supplement guidance is read against your own results, while Hundred Health discounts the supplements you already buy. Function Health is $365 a year, marketed as about a dollar a day and charged annually, for 160+ lab tests annually with testing twice a year. Hundred Health is $16/month, billed annually at $199, for 100+ lab tests, analyzed once a year. So the decision comes down to shape rather than category: a platform that checks in twice a year and ties your routine to your data, or one deep annual workup at the lower of the two prices with a hundred-day plan attached.

Does Function Health wire supplement guidance to your data, or does Hundred Health discount what you already buy?

Function Health wires supplement guidance to your own biomarker data, while Hundred Health discounts the supplements you already buy. Function Health's answer to supplements was an acquisition. SuppCo is now part of Function, so you can connect your supplement routine to your biomarker data. What the partner page describes is guidance rather than a member-priced storefront. Hundred Health goes the other direction. Its membership includes discounts on supplements, through a marketplace that carries supplements only.

Those solve two different problems. Function is answering "should I still be taking this?" by putting the routine and the labs on one screen. Hundred Health is answering "what is this costing me?" and leaving the judgment to you and the clinician insights that arrive with your annual analysis. If your stack is already settled and you mostly want the bill smaller, the discount is the practical one. If you suspect half of what you take is doing nothing, having that routine read against your own numbers is the one that answers it.

What arrives with your results at Function Health and Hundred Health?

Both memberships turn the panel into a plan, and they differ in what sits behind it. Function Health carries insights from top doctors and researchers on what your markers mean, alongside a personalized protocol to act on and member chat for questions about a marker. Hundred Health pairs clinician insights and a 100-day personalized plan with ongoing clinician guidance, described as clinician review plus ongoing support, and lists personalized prescription therapies — clinician-guided metabolic, hormone and longevity care — inside the same membership.

The difference is how far each membership follows the result. Function's plan is yours to run, which suits a reader who already knows what a flagged marker means for them. Hundred Health's hundred days come with a clinician attached and a prescription route if one is called for, which suits a reader who would rather be told where to start. Either way, ask where a follow-up question lands three weeks later: Function answers it in member chat, Hundred Health through the clinician attached to your plan.

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

Function Health is $365/year, marketed as about a dollar a day and charged annually, and the first-year membership is fully prepaid access to its 160+ lab tests.

Hundred Health publishes two tiers, both billed annually: $0.55/day, or $199/year, which its products page states as $16/month, billed annually at $199, and a second tier at $1.37/day, or $499/year. It is the $199 tier that comes in under Function's annual fee; the $499 one sits above it.

	Function Health	Hundred Health
Billing shape	First-year membership fully prepaid	Billed annually: $199/year, marketed as $16/month, or $499/year
Testing covered by the fee	Two rounds of testing inside the year	One annual analysis

How many biomarkers does each membership test, Function Health's or Hundred Health's, in 2026?

Function Health publishes the larger panel, 160+ lab tests annually, against Hundred Health's 100+ lab tests, analyzed once a year. Both count in lab tests rather than health scores, so this pair is unusually close to a like-for-like comparison, though the marker lists still matter more than the totals.

Cadence is the sharper difference. Function runs testing 2x/year and on-demand, at home or at 2,000+ lab locations, so a change you make in January can be measured before December. Hundred Health includes its 100+ lab tests, analyzed once a year, drawn at 5,000+ labs nationwide or from home. One analysis a year is a fair trade if what you want is depth on a fixed date; it is a harder trade if you are changing something and want to see whether it moved.

How fast do results come back from Function Health and Hundred Health, and is biological age included?

Function Health's results start arriving within 48 hours; Hundred Health's take up to two weeks.

Function Health: rest of the panel follows as the labs report, after the first batch; its Biological Age test is derived from Phenotypic Age.
Hundred Health: confirms results arrive in up to two weeks; its biological age and trends over time live in the member dashboard.

The bottom line: does Function Health or Hundred Health fit you?

Choose Function Health if you want more of the year covered: $365/year for 160+ lab tests, testing twice a year, biological age included and run twice, first results typically within 48 hours, and supplement guidance tied to your own biomarker data. Choose Hundred Health if you want one thorough annual analysis at the lower price: $16/month, billed annually at $199, for 100+ lab tests, clinician insights, a 100-day plan to act on, and a member discount on the supplements you already take.

Superpower: clinical answers, not an explanation or a protocol cycle

Both memberships hand you something on a date and then set the pace themselves: Function's twice-yearly read comes with member chat that explains results but stops short of medical advice, and Hundred Health's 100-day plan runs to a clinician-reviewed schedule, so a question your results raise three weeks later gets an explanation or waits for the next scheduled point of contact. Superpower puts that conversation on your schedule instead. $349/year, flat and all-in, includes a 24/7 care team you message on any day of the membership, alongside a personalized action plan written from your own results and revised as they move. Ask in week three and the answer comes in week three, from clinicians who can tell you what to do about a marker rather than only what it means, with no tier to upgrade to and no review point to wait for. That is the kind of contact that led 60% of members to say Superpower identified something previously missed or overlooked by a doctor.

An explanation is not the same as an answer. Start your health journey with Superpower and get one on the day the question comes up.

Frequently asked questions

Hundred Health's entry tier is the lower of the two at $16/month, billed annually at $199, with a second tier at $499/year. Function Health is $365/year, marketed as about a dollar a day and charged annually, with the first year fully prepaid. Each membership stops somewhere different, so compare what the year covers: Function includes two rounds of testing, while Hundred Health prices specialty screening outside its annual analysis.

Function Health publishes the larger panel, 160+ lab tests annually, against Hundred Health's 100+ lab tests, analyzed once a year. Both figures count lab tests rather than derived health scores, so they are closer to a like-for-like comparison than most pairings. Hundred Health also offers specialty work such as full-body MRI, cancer screening and gut analysis, priced separately from the membership.

The two describe the clinical side of the membership differently. Function Health explains results through insights from top doctors and researchers, with member chat for follow-up questions about a marker. Hundred Health describes clinician insights and a 100-day personalized plan alongside ongoing clinician guidance, and lists personalized prescription therapies in the membership. If a conversation matters to you, ask each one how a follow-up question gets answered before you join.

It depends on what you want the year to do. Function Health suits someone who wants more measurement and faster feedback: testing 2x/year and on-demand, 160+ lab tests, biological age tested twice a year, and results starting within 48 hours of testing. Hundred Health suits someone who wants one thorough annual analysis at $16/month, billed annually at $199, with a 100-day plan and supplement discounts. Superpower is a third model, pairing an action plan with on-demand care-team messaging between tests.
