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.

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.

AG1

The daily greens powder: vitamins, minerals, probiotics, and adaptogens in one scoop, on a monthly subscription. Polarizing on price, but the category's most popular all-in-one foundation.

Eight Sleep

A smart mattress cover that heats or cools each side of the bed through the night, adjusting automatically from your sleep data. Consistently the most-cited sleep upgrade in the longevity crowd.
