# Research Synthesis: NAD+ Biomarker Effects — full paper

## Abstract

This paper synthesizes evidence on NAD+ biomarker effects across 24 accepted source papers and 1531 high-confidence extracted claims.

The evidence profile contains 2 direct clinical sources, 22 adjacent clinical sources, and no sources classified primarily as mechanistic or model-system evidence, with 61 cross-study disagreem…
