How to read this NAD+ reference register

These are the NAD+ research citations behind the NAD+ and precursor studies summarized across this site. The list runs from the human precursor trials and mechanistic reviews through the IV NAD+ pilots to the most recent 2025-2026 evidence syntheses. Each entry carries a DOI and a PubMed link where available. Bracketed numbers in the text — [1], [2], and so on — refer to the matching entry here. This digest summarizes published research on NAD+ and its precursors; it is editorial commentary on public science, not medical advice.
