DSIP

Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide initially identified for its potential to encourage deep and restorative sleep. Present in the brain, hypothalamus, and various tissues, DSIP has been widely researched for its effects on sleep regulation, stress response, and neuroprotective activity. 

Unlike conventional sedatives, DSIP supports natural sleep processes without promoting dependency.

Beyond its role in sleep regulation, DSIP has demonstrated a range of biological activities, including potential involvement in stress response, thermoregulation, and neuroendocrine processes. The peptide is composed of nine amino acids arranged in the sequence Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu.

Current research applications include studies on:

• Sleep physiology
• Circadian rhythm biology
• Molecular pathways involved in regulating sleep and wakefulness
