Verdict in one glance

Best for

  • Users specifically interested in epigenetic biological-age testing

    If the biological-age metric is what you specifically want to track (versus a broader biomarker panel), Tally is purpose-built for that and has the most academically-credentialed founder team in the cohort.

Look elsewhere if

  • Users wanting a comprehensive biomarker baseline

    Function Health's 100+ biomarkers per draw at $30/month equivalent is meaningfully broader for similar money. Tally is narrow by design.

  • Users sensitive to delivery delays

    reviews document 9+ week delays vs advertised 2-4 weeks. If timely results matter, this is a real operational concern.

Our take

Tally Health is a credible biological-age testing service for users specifically interested in the epigenetic age question, with David Sinclair's name behind the methodology and a transparent membership pricing model. The honest counterweights are real: small sample (only 37 reviews, 3.6/5), recurring complaints about result-delivery delays running 9+ weeks vs the advertised 2-4, and the recent April 2026 acquisition by Infinite Epigenetics adding operational uncertainty. For most users wanting longevity-context lab data, Function Health's broader panel at comparable price is the better default; Tally only makes sense if you specifically want the epigenetic age metric.

Pros

  • Built around a single focused use case (epigenetic biological age testing)
  • David Sinclair (Harvard) as scientific founder
  • Transparent membership pricing tiers ($129/mo for 4 tests/year, $159/mo for 2)
  • Includes supplements and personalized recommendations alongside testing

Cons

  • 3.6/5 across only 37 reviews (small sample)
  • Recurring complaints about 9+ week result-delivery delays vs advertised 2-4 weeks
  • No findable profile to evaluate complaint-handling track record
  • April 2026 acquisition by Infinite Epigenetics adds operational uncertainty
  • Narrow scope (epigenetic age only) vs broader DTC lab competitors

Independent test results, recall history, supply-chain controls.

Epigenetic-age testing is a credible scientific methodology with peer-reviewed underlying research, but consumer-facing biological-age tests are still an evolving field with meaningful methodology variance across providers (TallyAge, GlycanAge, Elysium Index, NOVOS Age, etc.). David Sinclair as scientific founder gives Tally academic credibility; the question is whether the test result is actionable in practice.

What we verified (2)

  • Cheek-swab DNA methylation test methodology

    Test methodology

    TallyAge test is built on DNA methylation analysis, the same general approach as cohort competitors. The methylation-based biological-age field is real but young; methodology variance across providers is meaningful.

  • David Sinclair (Harvard) as scientific founder

    Scientific provenance

    Sinclair is well-published in longevity science, which gives Tally academic credibility relative to biological-age services without a comparable founder.

Pricing

15% weight
3.5/5

Value within the category, no surprise fees, refund policy.

$129-$159/mo for the membership is roughly comparable to Function Health's $30/month equivalent for 4 tests/year, but Tally is an epigenetic-only test rather than a 100+ biomarker panel. The premium is the focused product (biological age) plus supplements; whether it's worth the premium over Function depends on whether you specifically want the epigenetic result.

Frequently asked

Is Tally Health legit?

Yes in the narrow sense: Tally Health is a real epigenetic biological-age testing service founded by David Sinclair (Harvard), with the company recently acquired by Infinite Epigenetics in April 2026. The methodology (DNA methylation analysis on cheek-swab samples) is built on peer-reviewed research and Sinclair's name carries unique academic credibility in this field. No ; no active manufacturer lawsuits. Whether 'legit' means trustworthy enough for you is a different question. The honest counterweights are real: 3.6/5 across only 37 reviews (small sample), recurring complaints documenting result-delivery delays of 9+ weeks against the advertised 2-4 weeks, no findable profile to evaluate complaint-handling track record, and operational uncertainty from the recent acquisition. For users specifically wanting epigenetic biological-age testing, Tally is the purpose-built option; for comprehensive biomarker testing for longevity context at lower cost, Function Health is the default.

What is the TallyAge test?

TallyAge is an epigenetic biological-age estimate based on DNA methylation patterns from a cheek-swab sample. The methodology is built on Sinclair-lab research; the underlying science of methylation-based age estimation is real, though consumer-facing biological-age tests vary meaningfully in methodology across providers (TallyAge vs Elysium Index vs NOVOS Age vs GlycanAge). The result is a single number you can track over time as a proxy for biological aging speed.

How long does a TallyAge result actually take?

Tally advertises 2-4 weeks from sample receipt. reviews document actual delivery sometimes running 9+ weeks, with users reporting kits sent in late January 2026 still without results by mid-April. The April 2026 Infinite Epigenetics acquisition is recent enough that operational improvements may follow; pad your expectations and consider this a real operational risk if timely results matter to you.

How does Tally compare to Function Health?

Different products. Tally is a focused epigenetic-age service ($129-$159/month) with supplements; Function Health is a comprehensive lab-testing service ($365/year, $30/month equivalent) with 160+ tests across 100+ biomarkers per draw and MD review of every biomarker. For a comprehensive biomarker baseline, Function is broader for less money; for the epigenetic-age question specifically, Tally is purpose-built. They are complementary rather than competing services.

Is the David Sinclair connection real?

Yes. David Sinclair is a Harvard genetics professor well-published in longevity science, and he is the scientific founder of Tally Health. The methodology behind the TallyAge test draws on his research on DNA methylation and biological aging. The academic provenance is genuinely a differentiator vs biological-age tests without a comparable founder team.

What changed with the Infinite Epigenetics acquisition?

Infinite Epigenetics acquired Tally Health in April 2026. Tally remains a standalone consumer brand under the new parent per the acquisition announcement. Operational impact on result-delivery times and product changes is worth watching; we will update this profile if material changes happen.
