I read an article about the research on mice with NADH a couple of years ago . You stop producing NAD+ as you get older. It’s feeds the mitochondrial DNA. I don’t want to be a salesmen for it, but it does keep up my energy levels. Kind of amazing actually.
“A conserved NAD+ binding pocket that regulates protein-protein interactions during aging”
" NAD+ is a coenzyme that plays a central role in biological functions; it declines in humans as they age
→ Animal studies suggest that increasing NAD+ levels could provide a wide range of health benefits; human studies are now progress to determine if this is true.
