Read all about the latest NMN survey 2025 here
The quest for healthy aging and increased vitality has taken a major scientific leap forward in 2025. Read the NMN research 2025 here! One substance is at the center of this: nicotinamide mononucleotide, or NMN for short. As a natural precursor to NAD⁺ – a coenzyme essential for cellular energy and DNA repair – NMN offers numerous benefits, from improved muscle function to sharper cognitive performance, according to recent clinical studies. But what do the latest, peer-reviewed studies really say about the effects of NMN in humans? In this article, we take you through the most groundbreaking findings of 2025 and show why NMN is increasingly seen as the key to vitality in later life.
1. Liposomal NMN increases NAD⁺ levels more effectively
A 2025 randomized, double-blind study examined the effect of liposomal versus standard NMN supplementation on NAD⁺ levels in healthy adults. Participants received 350 mg of liposomal NMN, standard NMN or placebo daily for four weeks. Results showed that the liposomal NMN group showed a significant increase in NAD⁺ levels compared with both the standard NMN and placebo groups. Moreover, the increased NAD⁺ levels remained higher than baseline levels four weeks after stopping supplementation, indicating a long-term effect. The study concluded that liposomal NMN is a more efficient method of increasing NAD⁺ levels, possibly because of improved cellular uptake. Renue By Science
2. Improvement in physical performance and biological age
A 2024 clinical trial evaluated the impact of NMN supplementation on physical performance and biological age in healthy adults. Participants took 300, 600 or 900 mg of NMN daily for 60 days. Results showed significant improvements in the 6-minute walk test, with the greatest increase in the 600 mg group. In addition, participants reported improvements in energy, endurance and overall well-being. Epigenetic analyses suggested a delay in biological aging, indicating the potential anti-aging effects of NMN.
3. Support muscle and liver health.
A meta-analysis of nine clinical trials with a total of 412 participants between the ages of 40 and 80 examined the effects of NMN on muscle function and liver health. Results showed that NMN supplementation increased walking speed by 10-20%, especially in participants under 60 years of age. In addition, NMN reduced alanine aminotransferase (ALT) levels by about 15%, indicating improved liver function. These findings suggest that NMN may help maintain muscle mass and liver health with aging.
4. Improvement of insulin sensitivity.
A randomized, double-blind study examined the effect of NMN supplementation on insulin sensitivity in postmenopausal women with prediabetes and overweight or obesity. Participants received 250 mg of NMN or a placebo daily for 10 weeks. The NMN group showed a significant increase in insulin-mediated glucose uptake in skeletal muscle, as well as improvements in insulin signaling and gene expression related to muscle remodeling. These results suggest that NMN supplementation may improve insulin sensitivity and possibly reduce the risk of type 2 diabetes. alzdiscovery.org
5. Cognitive benefits and neuroprotection
Preclinical studies have shown that NMN can inhibit the buildup of beta-amyloid plaques associated with neurodegenerative diseases such as Alzheimer’s disease. In mice, NMN improved spatial working memory, gait coordination and neurovascular health. These effects are attributed to the increase in NAD⁺ levels and subsequent activation of sirtuins, which play a role in reducing oxidative stress and promoting mitochondrial function. Although clinical studies in humans are still ongoing, preliminary results are promising and suggest that NMN may play a role in preventing or delaying cognitive decline. BioMed Central
These recent findings highlight the potential of NMN supplementation in improving various aspects of health, including energy production, physical performance, metabolic function and cognitive health. Although the results are promising, further research is needed to determine the long-term effects and optimal doses of NMN in different populations.
The scientific insights from 2025 make it clear: NMN is much more than hype. From improved physical performance and insulin sensitivity to possible slowing of cognitive decline – the benefits are substantiated by increasingly robust human studies. Still, it remains important to choose high-quality, pure supplements that are effectively absorbed by the body.
