Fountain Life

Editor's pick

Longevity centers built around an intensive annual workup — full-body MRI, coronary CT, genome sequencing, and hundreds of biomarkers — with physicians who translate the data into a prevention plan. Membership-based, with locations in several US cities.

Biograph

A preventive-medicine clinic offering one of the deepest single-visit assessments available — advanced imaging, cardiac testing, and biomarker panels — followed by ongoing physician care. Membership pricing at the premium end of the market.

Lifeforce

A telehealth longevity program: quarterly at-home blood draws covering 50+ biomarkers, clinician consults, and protocols spanning hormones, peptides, and supplements. A middle path between a wellness app and a concierge clinic.

Superpower

An annual 100+ biomarker blood panel at a price that undercuts the concierge tier: one draw a year at 2,000+ Quest locations or at home, results and clinician insights in a single dashboard. HSA/FSA eligible; the budget-friendly comparison point to premium panel memberships.

Wild Health

Precision-medicine telehealth that starts with your DNA and bloodwork, then builds a personalized plan with a dedicated physician and health coach. Genomics-driven primary care without the clinic waiting room.

Parsley Health

Root-cause functional medicine delivered by telehealth: long visits with MDs, health-coach support, and testing aimed at chronic issues conventional 15-minute appointments miss. Membership-based; some insurance accepted.

Stelo by Dexcom

Dexcom's over-the-counter glucose biosensor — the first OTC-cleared CGM in the US, from the category's dominant medical manufacturer. 15-day wear, pay-as-you-go packs or a monthly subscription, FSA/HSA eligible, aimed at metabolic-health-curious users rather than diabetes management.

Tally Health

Epigenetic age testing from a cheek swab, built on a peer-reviewed methylation clock from a Harvard-lab pedigree. Membership includes twice-yearly TallyAge tests, a personalized action plan, and supplements. Now owned by the same parent company as TruDiagnostic, but runs as a separate consumer-lifestyle brand.

Marek Health

Telehealth built around serious bloodwork: comprehensive panels, guided optimization with clinical oversight, and treatment for hormone and metabolic issues. Popular with the data-driven fitness crowd.

TruDiagnostic

Epigenetic testing from a finger-prick sample: measures DNA methylation to estimate biological age and pace of aging using research-grade clocks. The de facto standard for tracking whether interventions are working.

Lingo

Abbott's over-the-counter continuous glucose monitor: a two-week biosensor and coaching app for anyone curious about their glucose responses — no prescription, no subscription required.

Labcorp OnDemand

Order standard lab tests yourself — no doctor visit — and get drawn at any Labcorp location. Covers the basics from lipid panels to thyroid and vitamin levels at straightforward per-test prices.

Galleri

A multi-cancer early detection blood test that screens for a shared signal across 50+ cancer types, many with no other screening option. Requires a prescribing clinician; intended to complement, not replace, routine screening.

BetterHelp

The largest online therapy platform: matched with a licensed therapist for weekly video, phone, or chat sessions plus unlimited messaging, on a weekly-billed subscription you can pause anytime.

SelfDecode

DNA and lab-result analysis focused on actionability: polygenic risk scores across hundreds of traits, with diet, supplement, and lifestyle recommendations tied to your genetics on an ongoing subscription.

DexaFit

Walk-in body-composition and metabolic testing: DEXA scans for precise fat, muscle, and bone density, plus VO2max and resting-metabolic-rate tests. Locations across the US, priced per scan.

WHOOP

A screenless wrist strap that grades your daily strain, recovery, and sleep, then tells you how hard to push. The hardware is included in the membership — beloved by athletes who want coaching, not notifications.

Levels

Continuous glucose monitoring for metabolic health: CGM sensors plus an app that scores how your meals, sleep, and workouts move your blood sugar — turning metabolic health into a feedback loop.
