ABOUT

Built for the obsessed.

Longeviz started with a simple question: everyone is taking supplements, but is anyone actually measuring whether they work?

Evidence grading

Every supplement in your stack is graded A to D, based on human research for longevity and healthspan outcomes. No hype, no miracle pills.

Biomarker tracking

Upload your blood panel and Longeviz tracks each marker against longevity-oriented targets, charts your trajectory, and runs an AI audit of your stack.

Streaks & accountability

Daily check-ins build streaks and a weekly leaderboard with friends. Consistency is the supplement that actually works.

THE SCALE

A to D. Nothing in between.

A

Strong human evidence

B

Emerging human evidence

C

Weak or mixed evidence

D

Little to no evidence

Longeviz is for people who take their health seriously: biohackers, athletes, and anyone who wants their routine grounded in evidence rather than marketing. Built by an independent team of evidence-first users. Not a medical device, not medical advice, just data.
