NAD+

Also known as: Nicotinamide adenine dinucleotide

Status

No approved product. Not FDA approved as an injection or infusion: this site's US review found no FDA-approved NAD+ drug product for any route. Oral NAD+ and its precursors (NR, NMN) are a separate question — they are sold as dietary supplements, which the FDA does not approve before sale — and an oral supplement's status says nothing about an injected or IV product.

What it is

Not a peptide either — a coenzyme in every living cell, central to energy metabolism. Levels decline with age, which is the entire premise of the longevity market built on it.

What published research measured

Human trials have studied precursors (NMN, NR) for raising blood NAD levels. Whether raising them changes health outcomes is an open question.
