# Alpha memo: Acute NAD+ precursor supplementation in older humans may rescue redox deficits without guaranteeing exercise gains across all contexts

**One-sentence alpha:** Nicotinamide riboside (NR) appears more likely to improve redox markers and exercise performance in older, redox-depleted humans, while the same molecule in young rats tended to impair performance, suggesting context (age, bas…
