NAD⁺ precursorEmerging
NMN (Nicotinamide Mononucleotide)
Direct NAD+ precursor. Early-phase clinical evidence shows raised blood NAD+ levels after oral dosing.
How it works
NMN (nicotinamide mononucleotide) is a direct precursor of NAD+, just one enzymatic step away. Because NAD+ falls with age and is central to energy, DNA repair and sirtuins, NMN is meant to offset that decline. The NAD+ rise is documented, but clinical longevity effects in humans remain open; the hype outpaces the evidence.
