Epithalon (also known as Epitalon or Epithalamin) is a synthetic tetrapeptide composed of four amino acids: alanine, glutamic acid, aspartic acid, and glycine. It was originally derived from a naturally occurring pineal gland peptide complex associated with aging and circadian regulation.
Epithalon is thought to work by activating the enzyme telomerase, which helps maintain or restore the length of telomeres—the protective ends of chromosomes that shorten with age. By supporting telomere stability and promoting cellular renewal, Epithalon may contribute to improved cellular longevity and regulation of oxidative stress. It has also been studied for its potential influence on melatonin production and circadian rhythm balance.
Epithalon has shown the following potential in studies:
Additional research is needed to confirm potential benefits and research indications.
Epithalon and Telomerase Activation (Khavinson et al., 2003)
In cultured human cells, Epithalon exposure was associated with activation of telomerase, the enzyme involved in maintaining telomere length. This correlation suggests that Epithalon may influence cellular aging pathways, although further research is needed to clarify its effects in living organisms.
Epithalon’s Anti-Aging Effects in Mice (Anisimov et al., 2003)
In a long-term mouse study, lifetime administration of Epithalon correlated with extended reproductive activity, reduced genetic damage, and increased longevity among the oldest animals. These findings indicate a potential relationship between Epithalon treatment and
