Does Superpower cost less than Rythm?

Yes, by a wide margin over a year. Superpower is a flat $199 a year, about $17 a month, no hidden fees. Rythm advertises $79 a month, but shipping and service fees add roughly $20 more per shipment, bringing the real cost to about $99 a month, or roughly $1,188 a year, about 6 times Superpower's annual price.

How many biomarkers does Rythm test?

Rythm's panel covers around 30 biomarkers and metrics, spanning hormones, heart, thyroid, metabolic, blood count, and kidney and liver markers, plus derived scores. Superpower runs 100+ health metrics from a single blood draw, more than 3x the baseline panel.

Is Rythm's at-home Tasso test accurate?

Yes. Rythm uses the FDA-cleared Tasso device, processed in CLIA-certified, CAP-accredited labs, and self-collected capillary samples have shown close agreement with standard venous blood in validation studies. Accuracy is essentially a tie with Superpower's venous draw; the differences are depth, care, and cost.

Does Rythm include a care team or prescriptions?

No. Rythm offers an AI dashboard and AI coaching, with no human clinical team, no prescriptions, and no supplement marketplace. Superpower includes 24/7 access to a clinical care team plus prescription and peptide access in its marketplace.

Is monthly testing better?

Not usually. Most biomarkers take a couple of months to move, so monthly full retests mostly capture normal variation. Superpower's approach is to set a complete baseline, then re-test the specific markers you're working on when it makes sense, rather than re-running everything every month.

Does Rythm have hidden fees?

Yes. Rythm's advertised price is $79 a month, but shipping and service fees add roughly $20 to every shipment, which isn't reflected in the headline price. Superpower's $199 a year is a flat rate: what you see is what you pay, with no added fees at checkout.

Can I use an HSA/FSA for Superpower?

Yes. Both Superpower and Rythm are HSA/FSA eligible, so you can put pre-tax funds toward your membership.

Is Superpower worth it?

For most people, yes. Superpower says 85% of members rated their action plan more useful, even life-changing, than a yearly checkup. You're paying for the wider panel, the care team, and the ecosystem that turn data into changes, not just another dashboard.

Superpower vs Rythm

Key takeaway:

Superpower ($199/year — about $17/month, flat, no hidden fees) is a full health membership: 100+ health metrics from one draw, a personalized protocol, a 24/7 clinical care team, and deeper add-ons from extra blood panels to cancer testing, gut microbiome, scans, supplements, and prescriptions. Rythm (advertised at ~$79/month, but closer to ~$99/month once shipping and service fees are added, about $1,188/year) is a convenient at-home tracker: ~30 biomarkers collected at home with the near-painless Tasso device, monthly retesting, and AI coaching, aimed at athletes and self-directed optimizers.

Superpower vs Rythm, compared

Superpower and Rythm both turn blood biomarkers into guidance, but they're built for different jobs. Superpower is $199 a year, about $17 a month, and bundles 100+ health metrics from a single blood draw, a personalized action plan, a 24/7 clinical care team, and a whole ecosystem of add-ons and a marketplace into one membership.

Rythm is an at-home tracker. Its $79-a-month subscription ships an at-home collection kit every 30 days — you take a near-painless capillary sample yourself with the Tasso device — measures around 30 biomarkers, and pairs the results with an AI dashboard and coaching. But that $79 isn't the real bill: shipping and service fees add roughly $20 more a month, pushing the real cost to about $99 a month, or roughly $1,188 a year. It's a snapshot you can take at home, with a price tag that grows at checkout; Superpower is the whole health picture at one flat rate, with people to help you act on it.

How biomarker testing services work

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 you get with Superpower

Superpower follows a simple path:

Join for $199 a year.
Give one blood draw at a lab, or at home for an added fee.
Receive 100+ health metrics in your dashboard.
Get a personalized action plan.
Message your clinical care team on demand, 24/7.

Testing reaches 2,000+ partner locations across 40+ states. From there you can go deeper into any area of health: additional blood panels, cancer testing, gut microbiome testing, imaging scans, a supplement marketplace with member-exclusive pricing, and prescription and peptide access (medications priced separately). A biological-age score is built into every membership. Results arrive in 5 to 10 business days.

What you get with Rythm

Rythm is built for convenience and self-directed tracking. You subscribe, a kit ships to your door every 30 days, 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. Results land in your dashboard in under 72 hours, paired with a Rythm Score, a biological-age read, and AI-generated insights and coaching.

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 about 30 markers with no deeper testing to layer on, and there's no human clinical team, no prescriptions, and no supplement marketplace.

What gets measured

This is the point buyers scrutinize most, and it's the clearest gap between the two. Both cover well-studied cardiovascular markers like ApoB, but the panels are very different sizes.

Headline count — Superpower: 100+ health metrics*; Rythm: ~30 biomarkers and metrics
Counted from — Both blend direct lab measurements with calculated ratios and scores
Method — Superpower: venous lab draw (or paid at-home draw); Rythm: at-home Tasso capillary collection (upper arm)

That's more than 3x the biomarkers on your baseline panel. Rythm's ~30 markers cover hormones, heart, thyroid, metabolic, blood count, and kidney and liver essentials, enough for a focused snapshot. Superpower's 100+ spans a wider whole-body baseline from a single draw.

*Superpower's 100+ combines direct lab measurements with calculated metrics like LMR and Ferritin:Albumin. Rythm's ~30 similarly includes derived ratios and scores such as its Rythm Score and biological age, so the two are counted on comparable bases.

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.

Turning results into action

This is where the two diverge most. Superpower includes 24/7 access to its clinical care team for any questions you need answered, plus prescription and peptide access covering GLP-1, TRT, and clinically appropriate peptides (medications 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.

*Compounded medications are not FDA-approved and are not evaluated by the FDA for safety, effectiveness, or quality. A patient-specific prescription is required, and Rx products are prescribed only when clinically appropriate. Rx products are not available in all states. See informed consent.

Testing cadence: smart, not constant

Rythm's model is monthly: a fresh kit every 30 days, a fresh full panel every month. 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 30-day clock delivers limited incremental value over testing when something has actually had time to shift.

Superpower takes the opposite approach. You get a complete baseline, plus your choice of optional add-on panels for the specific biomarkers you're most interested in. Then you re-test when it actually makes sense to, rather than paying to re-run everything on a monthly clock. A full 100+ metric follow-up is a single $179 add-on when you want a fresh whole-body read.

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

Cost and value compared

This is the most decisive gap. Superpower is $199 a year, about $17 a month, one flat membership, no hidden fees. What you see is what you get.

Rythm advertises $79 a month, but that's not the price you actually pay. Shipping and service fees, never disclosed on the pricing page, add roughly $20 to every shipment, so the real cost is closer to $99 a month, or roughly $1,188 a year, nearly $240 more than the advertised rate lets on. That's a hidden fee, not a rounding error: the number Rythm quotes you isn't the number it charges you, and the gap repeats every 30 days for as long as you subscribe.

Superpower doesn't play that game. There's no asterisk on the $199-a-year price and no second number that shows up once you're already checked out.

That's roughly 6 times Superpower's annual price once Rythm's fees are counted, and Superpower's $199 also bundles the protocol, the clinical care team, the supplement marketplace, prescription access, and the option to add deeper testing, none of which Rythm offers.

Both are HSA/FSA eligible, so pre-tax dollars can cover either. The value question is simple: for roughly 6x the yearly cost, Rythm gives you a narrower panel on a monthly clock. Superpower gives you a wider baseline, everything you need to act on it, and a price that doesn't change once you're in.

Best fit for you

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.

Our take

Rythm is a slick at-home tracker. Near-painless Tasso collection, sub-72-hour results, and a clean AI dashboard make it genuinely convenient for athletes who want to watch a focused set of markers month to month. On accuracy, it holds its own.

But it stops at a snapshot, and the price on the box isn't the price you pay. A ~30-marker panel, an AI dashboard, added fees at checkout, and a monthly clock is a narrow, expensive way to track your health, and it leaves the hardest part, knowing what to do next, to you. Superpower gives you 100+ health metrics from one draw, then a personalized protocol, a 24/7 clinical care team, and the option to go deeper into any area of health, all for a flat $199 a year, roughly 6x less than Rythm's real annual cost once its fees are counted.

A dashboard is only as good as what you do with it. Superpower pairs the wider read with the people and the ecosystem to act on it, and 85% of members rated their action plan more useful, even life-changing, than a yearly checkup. Get the whole picture, not a monthly sliver.
