Boosting Cellular NAD+ Precursors
To restore declining NAD+ levels, we rely on cellular precursors. Nicotinamide Mononucleotide (NMN) is an active precursor that rapidly converts into NAD+ in the body.
Cellular Absorption Pathways
NMN utilizes a specific transporter called Slc12a8 to enter cells directly:
- Bioavailability: Sublingual or liposomal formulations bypass stomach acid digestion, entering the bloodstream directly.
- Metabolic Health: Supplementation supports insulin sensitivity, cardiovascular health, and physical stamina.
