Key takeaway:

Rythm is a convenient at-home tracker: $79/month ($948/year, with a discounted first order) for 25+ markers across six categories, collected at home with the near-painless Tasso device and paired with an AI dashboard and coaching, aimed at athletes and self-directed optimizers. However, if you're looking for more post-testing actionable support at a lower price, Superpower is $349/year and pairs a personalized action plan with 24/7 clinical care-team messaging between tests, and 36.3% of Superpower members reduced their biological age score between their first and second year.

What is Superpower, and what is Rythm?

Superpower and Rythm are both biomarker testing services. A biomarker testing service offers blood-based testing, usually on a membership, that measures your biomarkers at set intervals. Biomarkers are measurable signals in your blood, things like cholesterol, blood sugar, and hormones.

Some platforms stop at data and a dashboard. Others turn those results into a plan you can follow and give you people to help. Two questions separate them: how much do they measure, and what do they help you do next?

Superpower and Rythm answer both differently. One is a full membership with depth and care built in; the other is a convenient, self-serve monthly tracker.

What does Superpower include?

Superpower includes a $349/year membership covering 150+ health metrics, a personalized action plan, a built-in follow-up draw, and 24/7 clinical care-team messaging. Superpower follows a simple path:

  1. Join for $349 a year.
  2. Give your initial blood draw at a lab, or at home for an added fee.
  3. Receive ~90 health metrics in your dashboard.
  4. Get a personalized action plan.
  5. Give a built-in follow-up draw later, retesting ~60 biomarkers.
  6. Message your clinical care team on demand, 24/7.

Testing reaches 2,000+ partner labs, or at home for an added fee. Results land in your dashboard 5-10 business days after each draw.

Among those results is a biological-age score, included in every membership. It's a single number for your whole body, so an optional OrganAge add-on breaks it into nine organ-level scores, across systems like metabolism, inflammation, liver, and kidney health, showing you which ones are pulling the total up or down.

From there you can go deeper into any area of health: additional blood panels, cancer testing, gut microbiome testing, and imaging scans. Acting on any of it happens in the same place, through a supplement marketplace with member-exclusive pricing and prescriptions, available through the marketplace when clinically appropriate, priced separately.

What does Rythm include?

Results land in your dashboard within 48 hours, paired with a Rythm Score, a biological-age read, and AI-generated insights and coaching. Rythm is built for convenience and self-directed tracking. You subscribe monthly, a kit ships to your door, and you collect a capillary sample yourself from your upper arm with the Tasso collector — a near-painless at-home device, not a venous draw — then send it back for free pickup.

Its at-home collection is genuinely low-friction — no lab visit, no venous draw — and fast turnaround is a real strength. But it's a single panel of 25+ markers with no deeper testing to layer on, and there's no human clinical team, no prescriptions, and no supplement marketplace.

What biomarkers do the Superpower and Rythm memberships measure in 2026?

Both cover well-studied cardiovascular markers like ApoB, but the panels are very different sizes. Both also report a biological-age score alongside the panel itself.

SuperpowerRythm
Counted fromDirect lab measurements plus calculated values, counted together across both drawsBlood biomarkers tracked on its monthly panel
Panel coverageWider whole-body baseline from the initial draw25+ markers spanning hormones, heart, thyroid, metabolic, blood count, and kidney and liver essentials

*Superpower's 150+ spans two draws — ~90 from the initial draw plus a built-in follow-up retesting ~60 of the same markers — combining direct lab measurements with calculated metrics like LMR and Ferritin:Albumin. Rythm's 25+ is its own published figure for the blood biomarkers it tracks; Rythm also reports derived outputs such as its Rythm Score and a biological-age read. Rythm re-runs its full panel every month, while Superpower's total reflects one baseline plus one retest a year.

Test accuracy: essentially a tie

Accuracy is not where these two differ. Rythm's Tasso collector is FDA-cleared, and its samples run through CLIA-certified, CAP-accredited labs. Self-collected capillary blood from Tasso devices has shown close agreement with standard venous samples in validation studies, so for the markers both platforms run, you can trust the numbers either way. Superpower uses a standard venous draw processed in CLIA-certified labs.

Treat accuracy as parity. The real differences are depth, care, cadence, and cost.

What support and next steps do Superpower and Rythm offer?

Superpower includes 24/7 access to its clinical care team for any questions you need answered, and it adds what Rythm doesn't. This is where the two diverge most. Prescriptions are available through the marketplace, when clinically appropriate, priced separately. A curated supplement marketplace offers member-exclusive pricing, and you can layer on deeper testing, from additional blood panels to cancer screening, gut microbiome testing, and scans, as your questions get more specific.

Rythm works differently. It gives you an AI dashboard, a Rythm Score, supplement suggestions, and AI coaching, but there's no human clinical team, no prescriptions, no supplement marketplace, and no deeper tests to add.

Rythm gives you a snapshot. Superpower gives you a whole health ecosystem with on-demand access to a team of clinicians to help you use it, not just numbers on a dashboard.

Testing cadence: smart, not constant

Rythm's model is monthly: a fresh kit every month, a fresh full panel each cycle. That sounds thorough, but most biomarkers take a couple of months to move in any direction, so month-to-month, a lot of what a full retest captures is normal biological variation, not real change. Retesting everything on a monthly clock delivers limited incremental value over testing when something has actually had time to shift.

Superpower takes the opposite approach. You get a complete ~90 metric baseline up front, then a built-in follow-up draw later in the membership year that retests ~60 of those markers — 150+ tests across the two draws — not the full panel on a monthly clock. Want to go deeper on a specific area sooner, add-on panels are available on your own schedule.

Test smart, not constantly. Monthly full retests mostly measure noise.

What are the official 2026 membership prices for Superpower and Rythm?

Superpower is $349 a year, one flat membership, no hidden fees.

  • Superpower: HSA/FSA eligible, so pre-tax dollars can cover it, with no asterisk on the $349-a-year price.
  • Rythm: HSA/FSA eligible too, at $79 a month, or $948 a year, plus shipping and tax, with a discounted first order.

Who is Superpower best for, and who is Rythm best for?

Superpower is best for:

  • Everyone who wants a complete baseline picture of their health.
  • People who want all their health data in one place.
  • People who want a protocol and a clinical care team, not just numbers.
  • People who want the option to go deeper: cancer testing, gut microbiome, scans, supplements, and Rx.
  • People who want to spend far less per year.

Rythm is best for:

  • Athletes and optimizers who want high-level wellness advice and coaching from an AI dashboard, not clinical care.
  • People who want low-friction at-home collection with fast turnaround.
  • People tracking a focused panel of hormone and performance markers, including while on TRT, HRT, or GLP-1s.

The final word: does Superpower or Rythm fit you?

Rythm's fit is clearest for athletes who want near-painless at-home Tasso collection, sub-48-hour results, and a clean AI dashboard to watch a focused set of markers month to month. On accuracy, it holds its own.

But it stops at a snapshot. A single panel of 25+ markers on a monthly clock, read through an AI dashboard, is a narrower way to track your health, and it leaves the hardest part, knowing what to do next, to you.

Superpower's ~90 health metrics from an initial draw, plus a built-in follow-up draw retesting ~60 of them — 150+ tests in all — come with a personalized action plan and a 24/7 clinical care team. On price, that's a flat $349 a year against Rythm's $948, plus shipping and tax.

Superpower: a whole health picture with a care team, not just a monthly snapshot

A dashboard is only as good as what you do with it, and Rythm's monthly snapshot leaves you reading a Rythm Score and AI coaching prompts on your own, with no clinician to weigh in between tests. Superpower pairs the same kind of blood data with a personalized action plan and 24/7 on-demand care-team messaging. 93% of members rated their Superpower Health Action Plan as more useful or even life-changing compared to their yearly checkup. Deeper testing, from cancer screening to gut microbiome testing and scans, sits inside the same flat $349-a-year membership, well under Rythm's $948-a-year subscription.

Starting your health journey with the whole picture, not a partial one, begins with a single blood draw. Start your Superpower membership and get the full picture, not a monthly sliver.
