If you're someone who is interested in anti-aging supplements, chances are you've come across NMN and its potential benefits. According to animal studies, NMN has shown promising results in slowing down the biological hallmarks of aging, leading to a surge of excitement in longevity supplement research. In fact, a few human trials are ongoing to see if a similar response is observed in humans. With the decline of NAD levels being linked to various age-related diseases, the hope is that NMN, as the direct precursor to NAD, can extend longevity and boost levels.
