NAD+
Nicotinamide Adenine Dinucleotide
NAD+ is a vital coenzyme present in every cell that plays crucial roles in energy metabolism, DNA repair, and cellular aging processes. As NAD+ levels naturally decline with age (by ~50% by age 50), supplementation through IV therapy or injections aims to restore cellular energy production, activate longevity pathways through sirtuin proteins, and support mitochondrial health. Research demonstrates significant improvements in cognitive function, physical performance, and biomarkers of aging.
Clinical Benefits
Mechanism of Action
NAD+ functions as an essential coenzyme in over 400 enzymatic reactions, primarily serving as an electron carrier in cellular respiration and energy metabolism. In mitochondria, NAD+ accepts electrons from metabolic substrates and transfers them through the electron transport chain for ATP synthesis. NAD+ also serves as a substrate for three major enzyme families: sirtuins (SIRT1-7), poly(ADP-ribose) polymerases (PARPs), and CD38/CD157. Sirtuin activation by NAD+ promotes deacetylation of key proteins involved in metabolism, stress resistance, and longevity, including PGC-1α for mitochondrial biogenesis, p53 for DNA repair, and FOXO transcription factors for stress response. PARP enzymes utilize NAD+ for DNA repair processes, while CD38 represents a major NAD+ consumer that increases with age, contributing to age-related NAD+ decline.
