NMN
Nicotinamide Mononucleotide
NAD+ precursor backed by strong clinical evidence for boosting cellular energy and supporting healthy aging.
NMN (Nicotinamide Mononucleotide) is a precursor to NAD+, a coenzyme essential for cellular energy production and DNA repair that declines with age. Multiple RCTs and meta-analyses demonstrate that NMN supplementation effectively raises NAD+ levels in humans, with growing evidence for improvements in metabolic health, exercise capacity, and biological markers of aging. Competes with NR (Nicotinamide Riboside) as a NAD+ boosting strategy.

Kim M et al. • Nutrients (2022)
“These findings suggest the potential of NMN in preventing loss of physical performance and improving fatigue in older adults.”
Key Findings:
- 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.
- The NMN_PM group demonstrated the largest effect size for 5-STS (d = 0.72) and drowsiness (d = 0.64).
- Overall, NMN intake in the afternoon effectively improved lower limb function and reduced drowsiness in older adults.
- These findings suggest the potential of NMN in preventing loss of physical performance and improving fatigue in older adults.
Yang DL et al. • Journal of the International Society of Sports Nutrition (2026)
“NMN supplementation, while inhibiting inflammatory signaling in exercised human skeletal muscle, may also suppress mitochondrial replenishment from phagocytes to repairing myofibers.”
Key Findings:
- BFR-exercise increased the mitochondrial content in exercised muscle by 171% after 24 h of recovery.
- NMN supplementation, while inhibiting inflammatory signaling in exercised human skeletal muscle, may also suppress mitochondrial replenishment from phagocytes to repairing myofibers.
- Further research warranted to confirm findings
Noh H et al. • Journal of assisted reproduction and genetics (2026)
“NMN supplementation shows improvements for oocyte function across diverse preclinical models.”
Key Findings:
- NMN supplementation shows improvements for oocyte function across diverse preclinical models.
- Human transcriptomic data further highlight mitochondrial and oxidative pathways as key regulatory points during oocyte maturation.
- Standardised protocols and clinical trials are needed to evaluate NMN's translational potential in the context of human reproduction.
Christen S et al. • Nature metabolism (2026)
“This rct examined the effects of NMN.”
Key Findings:
- 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.
- Overall, these results indicate a dual effect of NR and NMN and their microbially produced metabolite NA: a sustained increase in systemic NAD+ levels and a potent modulator of gut health.

Wang JP et al. • Current pharmaceutical biotechnology (2025)
“NMN has positive efficacy in enhancing muscle function, reducing insulin resistance and lowering aminotransferase levels in middle-aged and elderly individuals.”
Key Findings:
- Based on changes in gait speed (SMD: 0.34 m/s, 95%CI [0.03, 0.66] p = 0.033), NMN had significant effects on muscle mass.
- Moreover, NMN had a better effect on ALT (SMD: -0.29 IU/L, 95%CI [-0.55, -0.03] p = 0.028).
- NMN has positive efficacy in enhancing muscle function, reducing insulin resistance and lowering aminotransferase levels in middle-aged and elderly individuals.
- NMN is an encouraging and considerable drug for anti-aging treatment.
