Supplements for longevity and Nicotinamide Riboside

Each entry’s own grades, side by side. A grade says how strong the evidence is for one outcome — it does not rank one entry over the other.

Goal guide

Supplements for longevity

13 compounds relevant to longevity, ranked by overall evidence grade.

Grade B13 graded outcomesrevised Jul 10, 2026

Assembled by the app from other entries in this library. It adds no evidence of its own — follow the links to the entries it draws on.

Compound or practice

Nicotinamide Riboside

The better-studied NAD+ precursor — reliably raises NAD+, still short on hard human outcomes.

Grade C2 graded outcomesrevised Jul 10, 2026

A structured monograph in Prometheus's bundled library. Its grades are the monograph's own reading of the evidence, not a peer-reviewed review.

Swap the two

Graded in both

Outcomes are matched by name. Two entries can describe the same outcome in different words, so one listed further down may still be graded in the other.

No outcome has the same name in both entries. They may still overlap under different wording — read the two lists below.
