DSIP Peptide

Meaning

DSIP Peptide, an acronym for Delta Sleep-Inducing Peptide, is a naturally occurring nonapeptide found in the brain and various body fluids that plays a significant role in regulating sleep and stress responses. Its primary function is associated with inducing the slow-wave sleep (delta wave) phase, which is vital for deep physical and hormonal restoration. Beyond its sleep-modulating effects, DSIP is also implicated in stress adaptation, pain perception, and the modulation of certain endocrine functions. Clinical interest lies in its potential to stabilize circadian rhythms and support neuroendocrine recovery in states of chronic imbalance or sleep deficit.
