Superpower vs Rythm

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 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 (plus shipping and tax) 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. It's a snapshot you can take at home; Superpower is the whole health picture, 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:

1. Join for $199 a year.
2. Give one blood draw at a lab, or at home for an added fee.
3. Receive 100+ health metrics in your dashboard.
4. Get a personalized action plan.
5. 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 on-demand access to a clinical care team you can message about your results any time, 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. Real clinicians, on demand, are what turn a number into a decision, not just another line on a dashboard.

Rythm gives you a snapshot. Superpower gives you a whole health ecosystem, with people to help you use it.

*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.

Superpower takes the opposite approach. You get a complete baseline, then re-test the specific biomarkers you're working on, 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, one flat membership. Rythm is $79 a month before shipping and tax, so the bare subscription already works out to about $948 a year, and the shipping and tax Rythm adds at checkout push a real year higher still.

That's already roughly 5 times Superpower's annual price, before fees, 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 several times the yearly cost, Rythm gives you a narrower panel on a monthly clock, and Superpower gives you a wider baseline plus everything you need to act on it.

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 frequent, at-home wellness tracking.
• 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. A ~30-marker panel, an AI dashboard, 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 $199 a year, a fraction of Rythm's annual cost.

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.
