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.
Marine n-3 Fatty Acids and Prevention of Cardiovascular Disease and Cancer
The New England journal of medicine (2019) · Rct · n=25871
During a median follow-up of 5.3 years, a major cardiovascular event occurred in 386 participants in the n-3 group and in 419 in the placebo group (hazard ratio, 0.92; 95% confidence interval [CI], 0.80 to 1.06; P=0.24).
Omega-3 fatty acids for intermittent claudication
The Cochrane database of systematic reviews (2024) · Meta analysis · n=1830
Omega-3 compared with a control may have little to no effect on ankle-brachial index (MD -0.02, 95% CI -0.08 to 0.04; 3 studies, 168 participants; very low-certainty evidence).
A systematic review and meta-analysis of the omega-3 fatty acids effects on brain-derived neurotrophic factor (BDNF)
Nutritional neuroscience (2024) · Meta analysis · n=587
The present systematic review and meta-analysis indicate the efficacy of omega-3 FAs in increasing the serum concentration of BDNF.
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 multiple meta-analyses showing EPA-dominant formulas >1g/day most effective. Effects plateau around 2-2.5g. Adjunctive use with antidepressants shows better outcomes than monotherapy.
AI-estimated from published studies. Interpret as directional guidance.
Omega-3 has a higher evidence score (9/10 vs 5.5/10) and wins in 3 of 3 categories.
For neuroprotection, Omega-3 has a higher relevance score (85 vs 70).
No known interactions between NMN and Omega-3 have been documented in our database. However, always consult a healthcare provider before combining supplements.
