D2C epigenetic biological-age testing brand cofounded by Harvard's David Sinclair, paired with a longevity supplement subscription
About
Tally Health is a direct-to-consumer epigenetic biological-age brand cofounded by David A. Sinclair, PhD and Whitney Casey, with Melanie Goldey as CEO since 2022. Its core product is the TallyAge Test, an at-home cheek swab that reads DNA methylation across 200,000+ CpG sites through the peer-reviewed CheekAge clock and returns a biological-age estimate in 4-6 weeks. The broader consumer model pairs repeat testing with a longevity supplement membership and algorithmic action plan. In April 2026, Tally was acquired by Infinite Epigenetics, the parent of TruDiagnostic, and continues as a standalone consumer brand.

What to Know
Signature approach
Tally turns epigenetic-age research into a consumer testing loop. A cheek-swab sample runs through the company’s CheekAge clock, trained on 8,000+ adults across 200,000+ methylation sites, then returns a single biological-age estimate and lifestyle-facing guidance. The model is wellness and self-tracking oriented: useful for trend awareness, not a medical visit.
What sets them apart
- Published clock. CheekAge appears across peer-reviewed papers in journals including GeroScience, Aging Cell, Frontiers in Aging, and iScience, giving buyers a clearer methodology trail than many consumer epigenetic tests.
- Cheek-swab fit. The model was trained for buccal samples rather than retrofitting a blood clock onto saliva.
- Consumer execution. Sinclair’s science profile, Casey’s L Catterton consumer-brand background, Goldey’s operating experience, and the Infinite Epigenetics acquisition give Tally unusually visible commercial backing for a DTC epigenetic test.
Before You Book
- Result interpretation. TallyAge is an educational epigenetic-age report with an algorithmic Action Plan; bring the result to your own clinician if you want medical interpretation.
- Depth of output. The test returns one biological-age number, not organ-system ages, pace-of-aging, telomeres, blood biomarkers, or hormone markers.
- Access and timing. US-only shipping, self-pay checkout, HSA/FSA eligibility through Truemed, and a typical 4-6 week result window.
- Company context. Tally now sits under Infinite Epigenetics alongside TruDiagnostic, while continuing as a standalone consumer brand.

In practiceAdd-ons, payment details, and coverage limits.
$249 buys the TallyAge cheek-swab test once: kit, lab processing, and the digital report, with no recurring commitment. The $129/mo Tally Health Membership bundles a TallyAge test every six months, the daily Vitality supplement, an algorithmic Action Plan, and 15% off other supplement SKUs. Standalone supplements run $59 - $84 each, with a 25% member discount. Insurance is not accepted. HSA/FSA eligibility runs through the Truemed widget at checkout. A serious self-tracking plan stacks Membership plus one or more supplements at roughly $2,000/yr - $2,500/yr.
Insurance: Self Pay · HSA/FSA: Eligible
Eligible via the Truemed widget at checkout on the TallyAge Test and supplement pages — Truemed advertises around 30% average savings. Tally does not bill any insurance directly; the Truemed flow generates the Letter of Medical Necessity that converts an HSA/FSA card into a payment method.
Frequently asked questions
Who founded Tally Health?
Tally was cofounded in 2021 by Harvard Medical School geneticist David A. Sinclair, PhD and Whitney Casey, a partner at L Catterton (the consumer-focused PE firm that seeded the brand). The company hired Melanie Goldey as CEO in September 2022 and publicly launched in March 2023.
Is Tally HSA/FSA eligible?
Yes. The TallyAge Test and supplements are HSA/FSA eligible via a Truemed widget at checkout, which advertises around 30% average savings. Tally does not accept traditional health insurance — the business is pure self-pay.
Where does Tally ship?
United States only. There is no international shipping. Test kits arrive in roughly a week and total turnaround for a TallyAge result is 4–6 weeks from when the kit arrives.
Does Tally have clinicians?
No. There are no physicians, NPs, or PAs on staff, and no clinician reviews the TallyAge result. The report is delivered as an algorithmic, educational output through app.tallyhealth.com. The Personalized Action Plan that comes with the Membership is also algorithmic rather than clinician-authored.
What changed after the Infinite Epigenetics acquisition?
On April 29, 2026, Infinite Epigenetics, the parent of TruDiagnostic, acquired Tally Health. Tally continues as a standalone consumer brand. Melanie Goldey remains CEO of Tally, and Dr. Matthew Dawson is CEO of the parent company. Acquisition terms were not disclosed.
Is the TallyAge Test a genetic test?
No. TallyAge measures epigenetics — DNA methylation patterns that change with age, lifestyle, and environment — not the SNPs you inherited. It does not return ancestry, carrier status, or pharmacogenomic data. The clock is the company's peer-reviewed CheekAge model, trained on 8,000+ adults aged 18–100 across 200,000+ methylation sites.
