Research Comparison
Epitalon (Epithalon, AEDG) vs NAD+ (Nicotinamide Adenine Dinucleotide)
A side-by-side research comparison of Epitalon (Epithalon, AEDG) and NAD+ (Nicotinamide Adenine Dinucleotide) drawn from Cobalt Peptides' peptide database records.
Epitalon (Epithalon, AEDG)
Epitalon (Epithalon, AEDG) is a synthetic tetrapeptide derived from a naturally occurring pineal gland peptide, composed of four amino acids (Ala-Glu-Asp-Gly). It has been extensively studied in Russian research for its role in regulating aging processes, particularly through telomerase activation and circadian rhythm modulation. The peptide is associated with cellular longevity, improved sleep regulation via melatonin production, and systemic anti-aging effects. Research suggests it may influence gene expression, antioxidant systems, and cellular repair pathways, with effects observed even at extremely low (microgram-level) concentrations.
NAD+ (Nicotinamide Adenine Dinucleotide)
Nicotinamide Adenine Dinucleotide (NAD+) is an essential coenzyme present in all living cells, playing a central role in energy production, DNA repair, and cellular metabolism. It functions as a key redox carrier, cycling between oxidized (NAD+) and reduced (NADH) states to drive mitochondrial ATP production. NAD+ levels decline significantly with age (up to ~10–50% across tissues), contributing to reduced mitochondrial efficiency, increased oxidative stress, and impaired cellular repair. Injectable NAD+ bypasses oral absorption limitations, providing immediate systemic availability and rapid cellular uptake.
