Short answer — for most people who want an ongoing, actionable longevity-focused lab membership, InsideTracker is the best single choice. It combines wide biomarker coverage, evidence-based interpretation, personalized lifestyle recommendations, and repeat testing/coaching options.
Why InsideTracker (best overall)
- Broad blood panels that target aging/metabolic/inflammation markers (lipids, glucose, HbA1c, CRP, hormones, iron, liver/kidney markers, etc.).
- Algorithmic analysis tied to published optimal ranges for longevity, with clear, prioritized recommendations (diet, supplements, exercise, sleep).
- Membership options that include periodic retesting, trend tracking, and integration with wearables and genetics.
- Uses CLIA-certified labs and is set up for longitudinal tracking, which is key for longevity monitoring.
Good alternatives depending on your exact goal
- TruDiagnostic — Best for epigenetic age tracking (DNA methylation clocks). If your primary interest is tracking “biological age” via methylation, they’re industry-leading and designed for repeated measures over time.
- Levels or NutriSense — Best for metabolic/glycemic longevity work. Continuous glucose monitoring (CGM) membership + coaching gives real-time actionable insight into diet/exercise effects on glucose control, which is strongly tied to aging risk.
- Life Length (and formerly TeloYears) — Best for telomere length testing. Telomeres are a specific aging biomarker; these services use validated lab methods for telomere measurement.
- Thorne + Thorne at-home testing — Good integrated option if you want lab testing plus supplement recommendations and practitioner access.
- LetsGetChecked / Everlywell — Cheaper at-home testing options for specific markers (thyroid, hormones, vitamin D, basic panels) if you don’t need full longevity analytics or coaching.
What to look for in a longevity lab membership
- CLIA-certified labs and validated testing methods
- Repeated testing and trend reports (not a one-off test)
- Actionable, evidence-based recommendations (not just raw numbers)
- Data portability (exportable results) and integrations (wearables/genetics)
- Optional access to coaching or clinicians for interpretation
Price and frequency
- Memberships vary: expect $100–$600+ per test depending on panel depth, and memberships or coaching add $20–$200/month. For most longevity markers, retest every 3–12 months depending on intervention and marker variability.
If you want, tell me your budget and which longevity outcomes matter most (metabolic health, epigenetic age, hormonal balance, telomeres, etc.) and I’ll recommend the single best plan and a testing schedule. Also consider discussing abnormal results and interventions with your clinician.
