NAD+
Nicotinamide adenine dinucleotide
A coenzyme found in every cell. Injections and drips have little controlled research.
What it is
Not a peptide but a coenzyme found in every cell, essential for turning food into energy and for DNA repair. Levels fall with age in some tissues.
How it's thought to work
Raising NAD+ is proposed to support cell energy and repair pathways linked to aging.
What the evidence shows
Small human trials of oral precursors (NR and NMN) show they raise blood NAD+ levels, with mixed effects on health measures. Directly injected or infused NAD+ has very little controlled human research.
Regulatory status
Not approved as a treatment for aging or general wellness.
Safety notes
Infusions commonly cause flushing, nausea and chest tightness, especially when given quickly.
