Short answer — for most people wanting an ongoing, evidence‑driven longevity tracking membership I recommend InsideTracker. If your primary goal is “biological age” (epigenetic clock) tracking, pair a service like TruDiagnostic for methylation clocks. For gut/metabolism focus, consider Viome. For low-cost clinical monitoring, use Quest/Labcorp or Ulta Lab Tests plus occasional specialist tests.
Why these (briefly):
- InsideTracker — best all‑around longevity membership: focused blood biomarkers tied to aging and disease risk, personalized lifestyle/supplement recommendations, repeat testing and progress tracking, and integrations with DNA/wearables. Good balance of clinical markers + actionable coaching.
- TruDiagnostic — research‑grade DNA methylation (epigenetic) clocks (Horvath/PhenoAge/GrimAge etc.) and longitudinal reports. Best if your main outcome is “biological age” not just standard labs.
- Viome — deep stool and/or RNA‑based metabolic profiling with diet/supplement recommendations oriented to metabolic and immune health (useful when gut health is a longevity priority).
- LetsGetChecked / Everlywell — convenient, subscription‑friendly at‑home kits and nurse/telehealth followup; good for straightforward repeat monitoring (lipids, HbA1c, testosterone, thyroid, vitamin D) if you prefer home sampling.
- Quest Diagnostics / Labcorp / Ulta Lab Tests (direct‑to‑consumer) — lowest per‑test prices for standard clinical labs. Best if you want full control and will get interpretation from a clinician or coach.
What to track for longevity (recommended panels):
- Glucose metabolism: fasting glucose, HbA1c, fasting insulin (or HOMA-IR)
- Lipids: full lipid panel + apoB if available
- Inflammation: hs‑CRP
- Liver/kidney: ALT/AST, creatinine, GFR
- Hormones: testosterone (men), estradiol (women as relevant), DHEA, SHBG
- Nutrients: vitamin D (25‑OH), B12, ferritin, magnesium
- Thyroid: TSH, free T4, free T3 if symptomatic
- Others: IGF‑1, homocysteine, omega‑3 index (if available)
- Biological age: DNA methylation clocks (TruDiagnostic/Elysium Index/etc.) or transcriptomic aging if you want deeper aging measures
Testing cadence suggestions:
- Standard blood biomarkers: every 3–6 months while you change interventions, then every 6–12 months once stable.
- Epigenetic clocks (methylation): every 6–12 months (changes are slower).
- Microbiome/transcriptome: every 6–12 months or when changing major diet/medication.
A few cautions:
- Decide whether you want clinically certified labs (Quest/Labcorp/InsideTracker) vs consumer kits (Everlywell/Viome); clinical labs are better if you want treatments prescribed.
- Epigenetic clocks are informative but still evolving; interpret trends rather than single numbers.
- Discuss abnormal results with your clinician.
If you want, tell me your budget, whether you prefer at‑home vs phlebotomy, and whether you care most about biological age vs classic clinical risk markers — I’ll recommend a single best plan and a sample testing cadence.
