Einfach gesagt: Based on the small number of RCTs involving mainly relatively healthy adults, short-term supplementation of NMN of 250-2000 mg/d did not show significantly positive impacts on glucose control and lipid profile.
Einfach gesagt: NMN has positive efficacy in enhancing muscle function, reducing insulin resistance and lowering aminotransferase levels in middle-aged and elderly individuals.

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.
3NAD+ therapy benefit/risk analysisSystematische Übersichtn=1,545 · large study2020
Einfach gesagt: Potential risks in raising NAD+ levels in various clinical disorders using NAD+ precursors include the accumulation of putative toxic metabolites, tumorigenesis and promotion of cellular senescence.
Braidy N et al. · Experimental gerontology (2020)
Potential risks in raising NAD+ levels in various clinical disorders using NAD+ precursors include the accumulation of putative toxic metabolites, tumorigenesis and promotion of cellular senescence.
Therefore, NAD+ metabolism represents a promising target and further studies are needed to recapitulate the preclinical benefits in human clinical trials.Crown
Einfach gesagt: Current evidence does not support NMN and NR supplementation for preserving muscle mass and function in adults with mean age of over 60 years.
Prokopidis K et al. · Journal of cachexia, sarcopenia and muscle (2025)
Current evidence does not support NMN and NR supplementation for preserving muscle mass and function in adults with mean age of over 60 years.
Future research should explore supplementation dosage, NAD+ baseline deficiency, and combined interventions.
Einfach gesagt: Results of preclinical and clinical studies confirm the potential benefits of NAD+ precursors for the treatment of AD.
Alghamdi M et al. · Journal of Alzheimer's disease : JAD (2024)
Results of preclinical and clinical studies confirm the potential benefits of NAD+ precursors for the treatment of AD.
However, further clinical studies are required to confirm the increasingly important value of NAD+ precursors as effective pharmacological interventions in the clinic.
10Blood pressureMeta-Analysen=349 · medium study2026
Einfach gesagt: However, the potential of NMN as a viable candidate for early-stage blood pressure management requires confirmation through long-term, large-scale, high-quality RCTs in future clinical studies.

Compared with the placebo, NMN supplementation was associated with a statistically significant but modest reduction in resting DBP (WMD, -2.15 mmHg; 95% CI: -3.68 to -0.61).
In contrast, the reduction in resting SBP was not statistically significant.
Notably, subgroup analyses revealed that NMN supplementation resulted in a significant reduction in SBP specifically among participants aged 60 years and older (WMD: -3.94 mmHg; 95% CI: -7.06 to -0.82).
Einfach gesagt: In this review, we systematically summarize the impact of NMN as a nutraceutical and potential therapeutic drug on cardiovascular diseases and emphasize the correlation between NMN supplementation and cardiovascular protection.
Deng H, Ding D, Ma Y, Zhang H, Wang N, Zhang C, Yang G. · International journal of molecular sciences (2024)
Both in vivo and in vitro studies have demonstrated that nicotinamide mononucleotide (NMN), as a NAD + precursor, alleviates the development of cardiovascular diseases such as heart failure, atherosclerosis, and myocardial ischemia/reperfusion injury.
Importantly, NMN has suggested pharmacological activities mostly through its involvement in NAD + biosynthesis.
Several clinical studies have been conducted to investigate the efficacy and safety of NMN supplementation, indicating its potential role in cardiovascular protection without significant adverse effects.
Einfach gesagt: This mechanistic RCT provides direct evidence that NMN enhances skeletal muscle NAD+ and improves insulin sensitivity, strengthening the translational case for NMN as a metabolic health intervention.

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.
19Mitochondrial content in exercised muscleRCTn=11 · very small study2026
Einfach gesagt: NMN supplementation, while inhibiting inflammatory signaling in exercised human skeletal muscle, may also suppress mitochondrial replenishment from phagocytes to repairing myofibers.

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.
Einfach gesagt: 14 days of supplementation with NR and NMN, but not Nam, comparably increases circulatory NAD+ concentrations in healthy adults.
Christen S et al. · Nature metabolism (2026)
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.
