NAD+ sublingual lozenges Sublingual NAD (Nicotinamide Adenine Dinucleotide) refers to taking NAD or its precursors (like NMN/NR) in forms like wafers or drops that dissolve under the tongue, allowing direct absorption into the bloodstream, bypassing digestion for potentially faster action on energy, DNA repair, and cellular health, though some sources suggest tablets are just as effective and more practical, with studies needed for long-term effects.
