NMN preserved brain volume, prevented neuronal loss, and improved cellular respiration in brain tissues in this study, providing hope for using NMN as an agent against neurodegeneration. 

The breakdown and deterioration of bone known as osteoporosis contributes to increased morbidity and mortality in older adults; NMN may fight or prevent this age-related bone loss.   

Heart attacks happen more in people once they get older, and aging makes it more difficult to recover. Combined therapy of NMN and melatonin protects the heart from further damage after heart attacks.

NMN may be effective for promoting new capillary growth and treating age-related diseases that occur from reduced blood flow and impaired vascular function, including the muscle loss called sarcopenia.
