Supplementing with NMN prevented the loss of muscle mass in mice by enhancing the function of their mitochondria — the energy powerhouses of our cells that tend to decline in function with age.

This study elucidates how hyperglycemia impacts muscle repair, which could have wide-reaching effects for treating age-related muscle loss and opening doors for studying regenerative muscle growth.

Supplemental selenium protects against diet-induced obesity in mice and extends lifespan in yeast, likely through the mineral's ability to inhibit a signaling pathway called IGF-1.  

NAD+ is crucial in fueling the seven different genes in our body that govern aging. These genes are called sirutins and NAD+ is the sirtuin activator.
