What is InsideTracker, and what is Rythm?
InsideTracker turns an Ultimate blood test into scores and a habit plan covering food, supplements, exercise, and lifestyle.
Rythm bills itself as "The World's Easiest Blood Test." A kit arrives each month, you collect a sample at home, and the results land in an app.
Both measure blood, and they diverge on where the sample is taken and how often. InsideTracker draws venous blood at a lab or through a mobile phlebotomist, while Rythm has you collect a small sample at home every month.
What does InsideTracker include?
InsideTracker's new-customer bundle costs $489 and covers a membership, an Ultimate blood test of up to 54 biomarkers, and the platform that scores and explains it.
The steps follow a five-part path:
- Join InsideTracker — Pair the Ultimate test with a membership, then pick a lab visit or a mobile draw.
- Tell us about you — Complete a profile of your nutrition, supplement, exercise, and lifestyle habits.
- Review analysis — Study your optimal and suboptimal scores and markers, then shape a plan from the habit changes on offer.
- Take action — Practice the habits, with ProTips and check-ins keeping you accountable, and sync a wearable.
- Retest and refine — Retest after 3 to 6 months to see the changes in your scores.
The membership adds Terra, an AI health guide, plus Nutrition DeepDive and a weekly Healthspan Habit Report. It renews at $149 a year.
What does Rythm include?
A $79 monthly subscription brings a Tasso+ kit each month, processing in Rythm's own CLIA-certified, CAP-accredited laboratory, a results dashboard, and an AI Coach with no usage limit.
Rythm describes three steps:
- At-Home Test — Collect a capillary sample yourself with the kit's Tasso+ device.
- Send (Mail or get picked up) — Scan the QR code on the sample bag for a free FedEx pickup, or drop the bag at a FedEx location.
- Results within 2 days — Your dashboard fills once the lab has the sample, and the Rythm Score unlocks after your first completed test.
The dashboard flags markers outside the displayed optimal range, and results export as a PDF, a CSV, or a share link. Billing runs every 30 days, and skipped months, up to 90 days in total, are not charged. Rythm sells no one-time purchases, and first-time buyers get a 90-day money-back guarantee.
What biomarkers do InsideTracker and Rythm measure in 2026?
InsideTracker headlines up to 54 biomarkers on one Ultimate test, and Rythm counts 25+ biomarkers in each monthly kit.
| InsideTracker | Rythm | |
|---|---|---|
| Initial draw | 46 biomarkers (44 distinct and 2 calculated) | 27-28 biomarkers (21-22 distinct and 6 calculated) |
| Follow-up draw | Next Ultimate test, $340 at the member price | A new kit every month, on the same published panel |
| Headline count | Up to 54 biomarkers per Ultimate test | 25+ biomarkers |
InsideTracker's 46 comes from its Ultimate Panel list. Rythm's range reflects the separate panels for men and women it sells, because, it says, one collection can carry only so many markers. Neither list includes urinalysis, so the counts share a basis, and per draw an Ultimate test measures more markers than a Rythm kit.
InsideTracker's add-ons are:
- Healthspan Category Tests — Single-category panels at $99 to $149, for members only.
- Hormones — An estradiol and progesterone add-on at $89.
- DNA — An at-home cheek-swab kit at $249, US only.
Rythm sells no extra tests yet, though it lists an add-on option on its roadmap.
What are the official 2026 membership prices for InsideTracker and Rythm?
InsideTracker costs $489 for a membership with one Ultimate test, and Rythm costs $79 a month.
A year of Rythm kits, twelve at $79, comes to $948, though members can skip months. That sits above InsideTracker's $489, but it buys twelve samples where InsideTracker's buys one. Checkout adds shipping and tax to Rythm's price.
InsideTracker renews at $149 a year, and a further Ultimate test is $340 at the member price. Its mobile draw adds $119.
Both are HSA/FSA eligible, InsideTracker through Truemed and Rythm at checkout.
Collection: a lab draw or a kit at home
InsideTracker draws blood at a lab or through a mobile phlebotomist, and Rythm sends a kit you use yourself.
InsideTracker's lab draws happen at partner lab locations across the US. A mobile phlebotomist who comes to your home or office adds $119.
Rythm's kit contains the Tasso+ device, which the company describes as FDA-cleared and says collects a capillary specimen into the standard tubes used across healthcare. A prepaid FedEx label sends the sample overnight to a lab Rythm owns. Kits ship within one business day and take two to three business days to arrive.
One test a year or a kit every month
Rythm is built around frequency, and InsideTracker is built around a considered retest.
InsideTracker recommends retesting after 3 to 6 months, and each Ultimate test costs $340 at the member price. Rythm recommends testing monthly, with at least three tests to establish a baseline before skipping.
Rythm says monthly tracking builds a detailed picture over time. If trend lines are what you want, that cadence is its honest strength.
Results speed, scores, and what reads them
Once a sample reaches Rythm's lab, results follow within 2 days, while InsideTracker's store page promises them within 7 business days.
Rythm's faster clock follows from its panel size, since it tests a much smaller set of biomarkers. The clock also starts at the lab, so shipping time comes first.
Scores differ as well. InsideTracker sells InnerAge as a $99 add-on, while Rythm includes Biological Age once you complete a second test. A state-licensed physician signs off on Rythm results before release, which is a lab step and not a consultation, and guidance comes from the AI Coach. InsideTracker's Terra answers questions from your report, and the platform is not a substitute for a licensed professional.

Where are InsideTracker and Rythm tests available?
Rythm is available in all 50 states, and InsideTracker draws across the US and in Canada.
Rythm needs a US shipping address that FedEx can reach and does not ship internationally. InsideTracker requires a mobile draw in New York, New Jersey, Rhode Island, Arizona, and Hawaii, though a member can test in a different state instead. Canadian members use the mobile draw too.
Who is InsideTracker best for, and who is Rythm best for?
InsideTracker is best for:
- People who want a broader panel drawn by a professional.
- People who want guidance on food, exercise, and supplements tied to their markers.
- People who want to retest one area with a Category Test.
Rythm is best for:
- People who want a fresh result every month, with no lab visit.
- People for whom speed matters, since results follow about 2 days after the lab has the sample.
- People anywhere in the 50 states, including where InsideTracker requires a mobile draw.
The bottom line
InsideTracker fits readers who want a broader panel, drawn by a professional a few times a year, with habit guidance attached. Rythm fits readers who want the shortest route from sample to result, repeated every month.
Both stop at advice. Neither sells supplements or prescribes, and Rythm's add-on testing is still on its roadmap.
Superpower picks up after the results. Both annual figures cited above, $489 for InsideTracker and $948 for 12 kits at $79 before shipping and tax, sit above Superpower's $199 a year in most states. One draw measures 100+ biomarkers, and Superpower AI reads them beside your wearables and medical records to write your Superpower Protocol, with AI and care team support from there. The marketplace carries supplements at up to 20% off, add-on tests and scans, and prescriptions available when clinically appropriate, priced separately. Superpower says 93% of members found their action plan more useful, even life-changing, than a yearly checkup.
Blood work is where a health plan starts, not where it ends. Build your home for health with Superpower today.
