NAD+ therapy delivers nicotinamide adenine dinucleotide — a coenzyme central to mitochondrial energy production, DNA repair, and sirtuin activation pathways associated with cellular longevity. NAD+ declines with age and chronic stress; IV replenishment bypasses the limited oral bioavailability of NAD+ precursors like NMN or NR and achieves systemic levels more rapidly. Sessions are longer than a standard Myers' and are paced slowly to minimise the mild…
