Overview
DSIP (Delta Sleep-Inducing Peptide) is a 9-amino acid neuropeptide first isolated from rabbit brain in 1977 during sleep research. It is named for its ability to promote slow-wave delta sleep, the deepest and most restorative phase of the sleep cycle.
DSIP crosses the blood-brain barrier and has been studied for its effects on sleep architecture, stress hormone modulation, and pain perception. Research has been conducted primarily in European academic institutions, with some clinical studies in humans demonstrating improved sleep efficiency and reduced sleep latency.
Mechanism of Action
DSIP modulates sleep architecture through multiple mechanisms: it influences serotonergic and GABAergic neurotransmission, reduces cortisol and CRH (corticotropin-releasing hormone) levels, and may affect melatonin secretion timing. Its sleep-promoting effects appear to normalize disrupted sleep patterns rather than inducing sedation, distinguishing it from pharmacological sleep aids.
