Effect of 12-Week Intake of Nicotinamide Mononucleotide on Sleep Quality, Fatigue, and Physical Performance in Older Japanese Adults: A Randomized, Double-Blind Placebo-Controlled Study
Nutrients (2022) · Rct · n=108
Significant interactions were observed between 5-STS and drowsiness. 5-STS of all groups on post-intervention and drowsiness of the NMN_PM and Placebo_PM groups on mid- and post-intervention showed significant improvement compared with those in pre-intervention.
Anti-inflammatory effects of nicotinamide mononucleotide (NMN) in human skeletal muscle after BFR-exercise
Journal of the International Society of Sports Nutrition (2026) · Rct · n=11
BFR-exercise increased the mitochondrial content in exercised muscle by 171% after 24 h of recovery.
The differential impact of three different NAD(+) boosters on circulatory NAD and microbial metabolism in humans
Nature metabolism (2026) · Rct · n=65
Ultimately, we propose a gut-dependent model for the modes of action of the three NAD+ precursors with NR and NMN elevating circulatory NAD+ via the Preiss-Handler pathway, while rapidly absorbed Nam acutely affects NAD+ levels via the salvage pathway.

Dietary Supplementation With NAD+-Boosting Compounds in Humans: Current Knowledge and Future Directions
The journals of gerontology. Series A, Biological sciences and medical sciences (2023) · Systematic review
Limitations are identified and future research directions are suggested to further our understanding of the potential efficacy of NAD+-boosting compounds for improving physiological function and extending human health span.© The Author(s) 2023.
Based on multiple RCTs showing dose-dependent increases in blood NAD+ levels. Effects vary significantly by formulation bioavailability. Most studies used 250-1000mg doses.
Based on RCT with n=111 NAFLD patients showing reduced hepatic inflammation markers and ceramide 14:0 levels. Conservative estimate given single study and disease-specific population.
AI-estimated from published studies. Interpret as directional guidance.
