Superpower vs Rythm

What is Superpower, and what is Rythm?

Superpower is built as a home for health, bringing your care together on one platform. A single yearly fee covers wearable data tracking, AI health coaching, biomarker testing, and a personalized action plan. It also includes a members-only marketplace for supplements and add-on tests, with prescriptions available when clinically appropriate, priced separately.

Rythm is an at-home blood testing company. It calls its kit "The World's Easiest Blood Test": a monthly subscription that ships a collection device to your door, picks the sample back up, and runs it in Rythm's own lab. In its words, Rythm uses "monthly tracking to build a detailed picture of your health over time."

Each gives you real blood results. They differ on the number of markers per draw and on what you can do once results arrive.

What does Superpower include?

The $349 annual membership comes with 150+ lab tests across two draws and a personalized action plan, backed by AI + care team support. It also includes wearable and medical record integration and a members-only marketplace for supplements and add-on tests.

Members follow a simple path:

1. Start with the $349 annual membership.
2. Sync your wearables and bring any medical records, earlier lab results, and AI chats you already have.
3. Get your blood drawn at a lab, or at home for an extra $119.
4. Metrics land in your dashboard within 10 days of the draw.
5. Your first Superpower Protocol turns the results into lifestyle changes, supplements, and more.
6. Send questions to AI + care team support at any point.
7. Later in the year, a follow-up draw built into your membership retests around 60 key trackable markers.

From there, your dashboard builds a digital twin, a 3D model drawn from your metrics. You do not have to wait on a lab to start. Medical records, wearable data, and past lab results you upload begin producing insights right away.

Two scores come with every membership. Your biological age condenses the whole body into a single number, and your Superpower Score reflects how close your biomarkers, taken as a whole, sit to optimal levels. Both refresh after each follow-up draw, so you can track change over time.

You can act on all of it without leaving the platform. Add-on panels and scans sit alongside supplements at up to 20% off in the member marketplace, with prescriptions available when clinically appropriate, priced separately.

What does Rythm include?

A Rythm subscription costs $79 a month and includes a monthly at-home kit covering 25+ biomarkers, free pickup of the sample, results in the Rythm app, and the Rythm AI Coach. Shipping and tax are added at checkout.

Rythm publishes a three-step process:

1. At-home test — Each month a kit arrives, and you collect a capillary sample yourself with the Tasso+ device, which Rythm describes as FDA-cleared.
2. Send — Mail the sample back, or get it picked up from your home by FedEx at no charge.
3. Results within 2 days — Rythm's own CLIA-certified, CAP-accredited lab runs the panel, and each biomarker arrives in the app with an explanation.

A Rythm Score unlocks after your first completed test and a Biological Age after your second. The AI Coach is included with every active subscription, with no usage limit.

A state-licensed physician signs off on results before they are released, as a laboratory step rather than a consultation. Rythm's FAQ is plain about its scope: Rythm does not prescribe medication, and it points members with symptoms or concerns to their primary care provider. It does not offer add-on testing yet, though an add-on option is on the roadmap.

What biomarkers do Superpower and Rythm measure in 2026?

Superpower's 150+ lab tests across two draws include about 90 on the initial draw. Rythm publishes 25+ biomarkers on one monthly panel. Its biomarker list names 30, five of them sex-specific, so each member's kit carries 27 or 28.

Rythm's FAQ explains why the panel splits by sex: "we are limited by the number of biomarkers that can be tested from a single collection."

Calculated markers go unlabeled on Rythm's list, so we tallied them by hand and arrived at six: three cholesterol ratios, remnant cholesterol, LDL cholesterol, and eGFR. Superpower's 87 include 15 urinalysis items that Rythm's list leaves out. Without them, the initial draw still covers 72 markers, against 27 or 28 on a Rythm kit.

Both panels cover hormone, thyroid, heart, metabolic, and kidney and liver markers. Superpower's initial draw includes ApoB, hs-CRP, testosterone, and cortisol, along with urinalysis, a complete blood count, HbA1c, and insulin. Progesterone, free T3, and fructosamine appear on Rythm's list but not on Superpower's initial draw.

Superpower's marketplace also carries add-ons:

• Scans and body testing — heart calcium, VO2 max, DEXA body composition and bone density, and a whole-body MRI from Prenuvo.
• Cognitive and brain health — ApoE genetic risk screening, plus amyloid plaque and tau protein tests.
• Specialty testing — An organ age panel, gut microbiome analysis, and whole genome sequencing.
• Hormones and reproduction — Prostate screening, sperm analysis, egg reserve, and active testosterone.
• Nutrition and toxin exposure — Methylation, minerals, vitamins, organic acids, environmental toxins, heavy metals, and mycotoxins.

Rythm sells one panel. Additional tests are not available yet.

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

Superpower costs $349 a year. Rythm costs $79 a month, billed every 30 days, which comes to $948 across twelve monthly kits.

Extras change both totals. On Superpower, a home draw costs $119 more, and New York and New Jersey members pay $599 a year because state fees apply. Rythm's home pickup is free, and shipping and tax are added to each kit. Its first-test discount changes from page to page, and a 90-day money-back guarantee covers first-time purchases.

A Rythm year can cost less than $948. Members can skip up to 90 days at a time without being charged, and there is no one-time purchase or quarterly plan. Rythm recommends completing at least three tests before skipping, to establish a baseline.

Superpower charges separately for add-on panels, tests, and scans. HSA/FSA funds work for either membership, since both are eligible for pre-tax dollars.

How often do Superpower and Rythm test?

Rythm tests more often, while Superpower runs two draws a year inside its price. Frequency is the center of Rythm's model, and it is a real strength.

Rythm recommends testing every month, with the option to skip up to 90 days for a cadence closer to quarterly. Twelve kits a year give twelve readings of the same markers, which suits someone watching a few numbers respond to training or diet.

Superpower schedules two draws each year. The first sets a broad baseline spanning about 90 markers, and a later follow-up, already paid for in the membership, retests around 60 of them. Add-on panels and scans in the marketplace cover narrower questions, and you book them on your own schedule.

How do Superpower and Rythm collect blood, and where?

Rythm collects every sample at home, and Superpower draws at a lab or at home for an added fee.

Rythm's kit uses Tasso+, a device that collects a capillary sample from the upper arm into the same Microtainer tubes used throughout traditional healthcare. There is no lab visit to book. Rythm is available in all 50 states, anywhere FedEx can deliver and pick up.

Superpower members can draw at one of 2,000+ partner lab locations, or at home for an extra $119. Superpower serves 41 states and Washington, D.C., and has not launched yet in Alaska, Arkansas, Hawaii, Louisiana, Mississippi, North Dakota, Rhode Island, South Dakota, or Wyoming.

Because Rythm is testing a much smaller set of biomarkers, speed favors Rythm. Its results arrive within 2 days of the sample reaching the lab, after a kit that ships within one business day. Superpower's results arrive within 10 days of the draw.

Superpower vs Rythm: artificial intelligence and next steps

Both companies put AI on top of your results. Rythm's AI Coach explains them and offers guidance, whereas Superpower AI writes an action plan from them and then coaches you through it.

The Rythm AI Coach "provides personalized explanations and guidance based on your health data." Alongside it, the app suggests supplements and dietary changes, which Rythm's terms describe as "for general informational and wellness purposes only." Rythm does not refer members to healthcare providers, and members share results with their own doctor by PDF, CSV, or link.

Superpower AI drafts the plan itself. It draws on your medical history, medications, wearable data, lab results, and any context you add, then keeps revising your protocol as new information arrives. Between draws, AI + care team support answers questions whenever they come up.

Comparing member marketplaces

Members shop add-on tests and supplements in a marketplace, with supplements discounted up to 20% and prescriptions available when clinically appropriate, priced separately.

Rythm's app suggests supplements, but there is no member-priced storefront, no prescription access, and no add-on tests yet. Buying what its suggestions point to happens somewhere else.

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

Superpower is best for:

• People who want one health platform instead of biomarker testing by itself.
• People who like a baseline of about 90 markers with a follow-up draw already built in.
• People who want AI-powered insights and health coaching shaped by all the metrics they track.
• People who would rather have add-on tests and scans, supplements, and prescription access all inside one membership.

Rythm is best for:

• People who prefer to collect samples at home and skip the lab.
• People who want to track a focused set of hormone, heart, and metabolic markers every month.
• People who want results within days of the sample reaching the lab.
• People living where Superpower has not launched, as Rythm ships to all 50 states.

Rythm vs Superpower: the bottom line

Each company puts genuine data in your hands. Rythm makes collection simple, returns results fast, and lets you watch a focused panel move month to month. But there are no add-on tests yet, and buying supplements or filling prescriptions happens somewhere else. On Rythm's default monthly cadence, a year costs $948 against Superpower's $349, which makes Rythm the more expensive of the two.

Within a single $349 membership, Superpower brings those steps together. Wearable data and medical records join your 150+ lab tests across two draws in one Superpower AI, which turns them into a protocol and coaching between draws. Supplements that fit your protocol are in the marketplace at member pricing, while prescriptions are available when clinically appropriate, priced separately. Superpower says 93% of members found their action plan more useful, even life-changing, than a yearly checkup.
