For your skin
The "longevity molecule" of cellular skincare. It boosts NAD+ levels directly, helping your skin cells behave like younger ones. Clinical trials show it improves skin elasticity and barrier strength by activating cellular repair genes. A top pick for age-reversal routines.

Direct precursor to NAD+ (Nicotinamide Adenine Dinucleotide) that enters cells via the Slc12a8 transporter; activates SIRT1 (the "longevity gene") to stimulate DNA repair, mitochondrial biogenesis, and epidermal barrier reinforcement while suppressing senescent-associated secretory phenotypes (SASP).
Why we tier this anecdotal
2 cited papers across 2 countries. Most of what's cited here is mechanism-level or in-vitro work. We track this as Anecdotal until controlled clinical trials accumulate.
