Your shortlist.

ZOE

A personalized nutrition program born from large-scale research: an at-home test kit (including a CGM and gut microbiome analysis) scores how your body handles foods, then coaches you through eating for your biology.

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.

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.

Seed

DS-01, a two-in-one prebiotic and probiotic with strains selected from published human trials and a capsule engineered to survive to the colon. Subscription-based, with an unusually science-forward pitch.

Oura Ring

Editor's pick

A titanium smart ring that tracks sleep stages, heart-rate variability, temperature, and readiness with best-in-class accuracy — and none of a smartwatch's bulk. Ring purchase plus a monthly membership for full insights.

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.
