Which costs less, Hundred Health or Rythm?

Hundred Health costs $199 a year, and Rythm costs $79 a month, which is $948 over twelve monthly kits (12 × $79, before shipping and tax). Rythm lets members skip up to 90 days without charge, so a member who tests less often pays less.

Which one measures more biomarkers per draw?

Hundred Health. Its annual panel lists 113 to 116 biomarkers, and Rythm's monthly kit lists 27 to 28. Rythm's panel differs for women and men, and Hundred's own headline is 100+ lab tests analyzed once a year.

Does Rythm collect blood differently from Hundred Health?

Yes. Rythm sends a kit with the Tasso+ device for a capillary sample taken at home. Hundred Health uses standard venous draws, at a partner lab or through an in-home phlebotomist.

Do Hundred Health or Rythm offer prescriptions or supplements?

Hundred Health offers weight-loss medication through its care program and sells supplements at up to 20% off retail to members. Rythm does not prescribe medication, and its supplement suggestions are informational.

Rythm reports within 2 days of the sample reaching its lab, and kits take about 2 to 3 business days to arrive. Hundred Health shows some results within 24 hours, and the full panel takes about two weeks.

Are Hundred Health and Rythm HSA/FSA eligible?

Yes. Both are HSA/FSA eligible, and Rythm notes it is not covered by insurance. Reimbursement depends on your plan, so check with your administrator.

Hundred Health vs Rythm: Features & Pricing (2026)

Key takeaway:

Hundred Health ($199/yr) turns 100+ lab tests, imported records, and synced wearables into a 100-day protocol written by clinicians. Rythm ($79/mo) mails a monthly at-home blood test kit and returns results within 2 days of the sample reaching its lab. If you want more than a protocol or a kit report, Superpower ($199/yr) goes beyond biomarker testing to be a true home for health. Its membership includes 100+ biomarkers from one lab or at-home draw and Superpower AI that builds a full action plan, with add-on tests and scans and a marketplace for supplements and compounded prescriptions (like peptides) available to members.

What is Hundred Health, and what is Rythm?

Hundred Health gives each member a 100-day health strategy. It starts from 100+ lab tests, adds medical records and wearable readings, and ends in a protocol written by clinicians.

Rythm markets "The World's Easiest Blood Test." A kit arrives monthly, you collect a sample at home, and its own lab reports back on 25+ biomarkers.

Both are built around the dashboard rather than the doctor's office. They part ways on rhythm: Hundred takes one look a year, and Rythm takes one every month.

What does Hundred Health include?

Hundred's $199 membership covers an annual panel of 100+ lab tests, record import, wearable syncing, a biological age readout, and a 100-day protocol.

The company summarizes its approach in three steps:

We build your complete health record — Labs come first, either at a partner site or at home, while your old records, imaging, and devices are pulled in.
Your health results, finally explained — Hundred reads labs and wearable data together and compares them with peers, adding physician-led commentary.
Get your 100-day action plan — Clinicians build a protocol across nutrition, supplements, exercise, and lifestyle.

Wearables that connect include Apple Health, Oura, Fitbit, Garmin, Peloton, and Whoop. Hundred's FAQ states that members don't currently speak to a physician inside the app.

What does Rythm include?

Rythm's subscription delivers a test kit every month, plus a dashboard, a Rythm Score, biological age, and an AI Coach with no usage limit.

Rythm's own three steps are short:

At-Home Test — Collect a capillary sample at home with the Tasso+ device.
Send (Mail or get picked up) — Ship the sample overnight, or schedule a free FedEx pickup.
Results within 2 days — Rythm's own laboratory reports after the sample arrives.

The Rythm Score unlocks after the first completed test, and biological age follows after the second. Members can download results or share a link with their own doctor. Rythm says its results are for general informational and wellness purposes.

What biomarkers do Hundred Health and Rythm measure in 2026?

Hundred Health lists 100+ lab tests in a single annual draw. Rythm lists 25+ biomarkers per kit, sorted into hormones, thyroid, heart, metabolism, blood count, and kidney and liver.

Counted from each published list with the same rule, the gap in markers per draw is wide:

	Hundred Health	Rythm
Initial draw	113-116 biomarkers (91-94 distinct and 22 calculated)	27-28 biomarkers (21-22 distinct and 6 calculated)
Follow-up draw	One annual panel; a full retest every 100 days is recommended	Monthly kit by default; skip up to 90 days
Headline count	100+ lab tests, analyzed once a year	25+ biomarkers

Hundred's count includes about 30 urine items, and Rythm's list names none. Rythm's FAQ explains that women and men get different panels because one collection can only support so many markers.

Hundred also sells add-on markers beyond the annual list:

Heart and lipids — Lipoprotein(a), ApoA1, LDL particle number, and oxidized LDL.
Nutrients and toxins — Omega fatty acids, homocysteine, zinc, and heavy metals.
Thyroid and stress — Thyroid antibodies, free T3, cortisol, and DHEA sulfate.

Rythm says an add-on option is on its roadmap but offers no extra testing at the moment.

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

Hundred's membership costs $199 a year. Rythm's is $79 a month, billed every 30 days, with shipping and tax added at checkout.

Twelve monthly kits at $79 add up to $948 a year, before shipping and tax, a figure Rythm does not print. Members can skip up to 90 days without being charged for skipped months, and first-time buyers get a 90-day money-back guarantee.

Hundred's price covers its lab tests, while optional add-on tests can carry separate fees. In New York and New Jersey, a lab testing fee of up to $248 a year applies to Hundred members. Rythm's at-home pickup is free.

Both are HSA/FSA eligible. Rythm adds that it is not covered by insurance.

How does each one collect your blood?

Hundred sends you to a lab or a phlebotomist, and Rythm sends a kit to you.

Hundred offers in-lab visits and in-home phlebotomy, so the sample is a standard venous draw. Rythm uses the FDA-cleared Tasso+ device to take a capillary sample at home, then tests it in its own CLIA-certified, CAP-accredited lab.

Kits typically ship within 1 business day and arrive in about 2 to 3 business days. Rythm recommends testing monthly and a minimum of three tests to establish a baseline.

How fast do results arrive, and what comes next?

Hundred posts its first results sooner, and Rythm finishes its smaller panel sooner.

Rythm promises results within 2 days of the sample reaching its lab, and a smaller panel helps. Hundred shows some results within 24 hours of the draw, though the full panel takes about two weeks.

A licensed physician signs off on each Rythm result before release, as a laboratory step rather than a consultation. Guidance comes from the dashboard and the AI Coach. Hundred's clinicians build a protocol once every result is in.

Prescriptions and supplements

Hundred Health offers both through its platform, and Rythm offers neither as a service.

Hundred's care program bills weight-loss medication on its own, starting at $99 a month, and independent licensed clinicians prescribe only after a consultation. Residents of Alaska, Illinois, Mississippi, and New Jersey cannot join it, and its charges are marked HSA/FSA eligible. Its member marketplace sells supplements at up to 20% off retail.

Rythm says it does not prescribe medication. Its app does show supplement and dietary suggestions, which its terms describe as information.

Where are Hundred Health and Rythm tests available?

Rythm is available in all 50 states to anyone with a U.S. shipping address and access to FedEx.

Hundred Health reaches 5,000+ partner labs, but in-lab visits are unavailable in Hawaii, North Dakota, South Dakota, and West Virginia. In-home draws are also unavailable in several states, including Idaho, Maine, and Wyoming.

Who is Hundred Health best for, and who is Rythm best for?

Hundred Health is best for:

People who want one broad panel and a protocol built by clinicians.
People who want records, wearables, and supplements in a single place.
People who want prescriptions available through the same platform.

Rythm is best for:

People who want to avoid lab visits and test at home every month.
People who care more about frequent readings than about a broad panel.
People who want results quickly, plus a money-back guarantee on a first purchase.

The bottom line

Hundred Health is the once-a-year option, with a clinician-built plan, a supplement store, and prescriptions on offer. Rythm is the frequent one, with a monthly home kit, free pickup, and results days after the lab receives the sample.

Between them, the choice is one panel a year or one kit a month. Rythm also lists no add-on tests and offers no prescriptions.

At $199 a year in most states, Superpower matches Hundred's fee and sits below the $948 that twelve Rythm kits cost, though Rythm samples every month. One draw covers 100+ biomarkers, taken at a lab or at home for an added fee, and Superpower AI turns those labs, your wearables, and your records into a Superpower Protocol, with AI and care team support on demand. The marketplace adds scans and add-on tests and discounts supplements by up to 20%, and prescriptions are available there when clinically appropriate, priced separately. Superpower says 93% of members found their action plan more useful, even life-changing, than a yearly checkup.
