Epithalon is a synthetic tetrapeptide derived from the naturally occurring pineal gland peptide epithalamin. This peptide is designed to mimic its biological counterpart's role in regulating the body's circadian rhythms and influencing lifespan. It functions by activating telomerase, an enzyme that extends the telomeres of chromosomes, thus promoting cellular longevity. Research on Epithalon began with its potential effects on aging and the immune system, attracting significant interest in its ability to enhance telomere repair and maintenance. Today, it is primarily studied for its effects on:
- Telomere maintenance
- Cellular aging
- Immune system modulation
- Pineal gland function
Secondary research interest includes its impact on antioxidant levels.
