DSIP

Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring nonapeptide originally identified for its role in supporting deep, restorative sleep. Present in the brain, hypothalamus, and various other tissues, DSIP has been widely researched for its effects on sleep regulation, stress response, and neuroprotection. Rather than acting as a conventional sedative, DSIP helps regulate sleep in a more natural way and is not associated with dependency, which is why it continues to be a focus of scientific study.
