NAD+

The essential coenzyme for cellular energy, studied for aging, DNA repair, and metabolic function.

In the literature, NAD+ appears most often in work focused on energy, longevity and anti-aging. Studies in this area tend to look at mechanisms and observed effects in laboratory and preclinical settings rather than outcomes in people, so the picture is best read as a map of where researchers have been curious — not as evidence of any benefit.

Because it is catalogued here under powder peptides, NAD+ also shows up in discussions of cellular repair. Coverage across those topics varies widely in quality and depth, and much of it is early-stage. Reading the underlying research directly is the only way to judge how strong any particular finding is.
