Two NAD+ precursors — same destination, different trial footprints
What this is
Head-to-head evidence table: NMN vs NR (Nicotinamide Riboside) (compound).
Why it matters
Both raise NAD+ metabolites in humans. TNiC standardizes on NMN for stack integration and Igarashi/Liao trial dosing. NR is defensible — do not combine high doses without physician oversight.
What to do next
Use the verdict row to pick a primary compound, then open both deep-dives and /shop verification checklists.

TNiC verdict
Tie on core NAD+ restoration. Choose NMN if you run TNiC stacks (SIRT1 pair, Mito Stack). Choose NR if your physician prefers NR-specific literature or you already respond well.
