Epithalon vs. NAD+: Longevity Research Comparison

Epithalon was developed as a synthetic analog of the pineal-derived tetrapeptide Epithalamin. Preclinical research from Vladimir Khavinson’s group has examined its effect on telomerase expression in cell lines and on senescence markers in rodents. NAD+ is an endogenous cofactor required for oxidation–reduction reactions in glycolysis, the TCA cycle, and the electron transport chain, and it is a substrate for the sirtuin family of NAD-dependent deacetylases. The two are only linked in the literature by their shared appearance under the “longevity research” umbrella term.

Both compounds ship as lyophilized powders in sealed sterile vials. Both are moderately hygroscopic and should be stored refrigerated pre-reconstitution and frozen post-reconstitution in aliquots. NAD+ is more sensitive to hydrolysis in aqueous solution than a small peptide — reconstituted NAD+ is best used within days if kept at 2–8 °C, or aliquotted immediately for −20 °C storage.
