Pinealon is a synthetic tripeptide (Glu-Asp-Arg) derived from the pineal gland, where it is thought to act as a peptide bioregulator influencing gene expression in neural and pineal tissues. Research has focused on its neuroprotective properties, with studies suggesting it may reduce oxidative damage in neural cells, support mitochondrial function in neurons, and influence the circadian clock mechanisms regulated by the pineal gland. Some research has examined Pinealon’s effects on melatonin secretion patterns and sleep quality in aged models, positioning it at the intersection of cognitive, longevity, and vitality research.
