How to read this list

Each numbered entry corresponds to the inline [N] markers throughout the site. The list spans the human precursor trials (NMN and NR), the mechanism and review literature, and the wider animal and cosmeceutical studies. Every figure quoted in the digest — the 22%/51%/142% NR dose-response, the NMN 250–900 mg/day doses, the roughly two-fold head-to-head — traces back to a named study below. Links resolve to PubMed; DOIs are included for direct lookup.
