RESEARCH DIGEST / NAD+ · SOURCES

NAD+ references: every study cited here, stamped to source

The complete citation ledger for this NAD+ digest — peer-reviewed journals, DOIs, and PubMed identifiers for each claim.

How to read this list

Every quantitative claim in this digest carries a bracketed marker like [4] that maps to the numbered entries below. Each entry gives the authors, title, journal, year, and a DOI plus a PubMed link so the source can be verified directly. The list spans the human precursor trials, the mechanism and ageing reviews, the IV pharmacokinetic work, and the model-organism studies cited across the site.
