Short answer — for most people who want ongoing, actionable longevity tracking, InsideTracker is the best single membership option. A few other good choices depend on your specific focus (metabolism, budget, clinician integration).
Top picks
- InsideTracker — Best overall for longevity tracking. Covers a broad set of longevity-relevant biomarkers (metabolic markers, lipids, inflammation, hormones, micronutrients), offers DNA integration, gives individualized lifestyle and supplement recommendations, and supports repeat testing and coaching. Good if you want data-driven, personalized guidance rather than just raw lab results.
- Levels — Best if your primary longevity goal is metabolic health. Uses continuous glucose monitors (CGMs) and software to track glycemic responses to food/exercise/sleep. Excellent for improving metabolic flexibility, an important longevity determinant.
- Thorne (testing + coaching) — Best if you want clinical-grade labs tied to supplement protocols and practitioner support. Thorne pairs testing with evidence-backed supplement recommendations and access to clinicians/coaches for follow-up.
- LetsGetChecked — Best budget-friendly recurring testing with telehealth. Monthly/quarterly subscriptions for panels (hormones, thyroid, lipids, male/female health) and nurse/doctor consults; convenient at-home kits and easy retesting cadence.
- Quest Diagnostics or Labcorp (via your clinician) — Best when you want the widest clinical test menu and fully clinical integration (prescriptions, specialist referrals). Not always a consumer “membership,” but arranging regular panels through a clinician gives the most direct medical oversight.
What to look for when choosing a membership
- Biomarkers covered: make sure it includes: hs-CRP (inflammation), fasting glucose/HbA1c, fasting insulin, lipid panel (ideally apoB or advanced lipids), IGF‑1, sex hormones, vitamin D, omega‑3 index, CMP, CBC, homocysteine. Add tests you need based on age/sex/family history.
- Actionability: personalized interpretation and clear, evidence-based recommendations you can act on.
- Retest frequency and cost: check how often retests are included and total yearly cost.
- Clinician/coach access: for abnormal results or medication decisions.
- Data integration: ability to combine with wearables, DNA, or CGM if you use them.
- Privacy and lab quality: clinical-grade labs and clear privacy policy.
Quick cautions
- Don’t start/stop prescription meds solely on a direct-to-consumer lab result without clinician input.
- Some advanced tests (NMR, genetic or specialty assays) add cost but may be worth it for specific concerns.
