Peptide ComparisonGlutathione vs NAD+
Both are Longevity & Cellular peptides.
Glutathione
gamma-glutamylcysteinylglycine
Half-life: Variable (~2-5 minutes IV; hours liposomal)
136 providers listed
NAD+
NAD
Half-life: ~1–2 hours (IV); variable (oral)
451 providers listed
NAD+ has a longer half-life than Glutathione, so it generally needs less frequent dosing.

About Glutathione
Master endogenous antioxidant tripeptide; neutralizes ROS, regenerates vitamins C and E, supports phase II liver detoxification, maintains intracellular redox balance
About NAD+
NAD+ is a coenzyme central to cellular energy metabolism, serving as an electron carrier in glycolysis, the citric acid cycle, and oxidative phosphorylation. It is also a required substrate for sirtuins (SIRT1–7) and PARP enzymes, which regulate DNA repair, gene expression, and mitochondrial biogenesis. NAD+ levels decline measurably with age; IV or subcutaneous delivery aims to restore intracellular pools more directly than oral precursors such as NMN or NR.
