DSIP Peptide

Delta Sleep-Inducing Peptide, or DSIP, is a synthetic peptide developed with the intention to regulate several systems and maintain normal endogenous functions. DSIP may not only regulate sleep cycle, as suggested by its name but may also play a role in regulating various physiological processes. DSIP is a nine amino acid-containing nonapeptide, endogenously found in neurons, plasma, and peripheral organs. Suggested to induce delta sleep in mammals, this neuropeptide also appears to possibly impact electrophysiological activity and possibly regulate the neurotransmitter levels in the brain. (1)

DSIP peptide was first characterized and examined during the years 1963 to 1977 and has since been widely studied by scientists. (2)  Initially regarded only for its potential as a sleep-including factor, DSIP was soon suggested to possess other potential actions, such as mitigating pain, sleeplessness, and withdrawal. In 1984, a DSIP-like material was also detected in breast milk with an almost 90% recovery rate. It is suggested that the naturally found milk proteins are easily absorbed in the gastrointestinal tract of infants. However, it is not known whether DSIP-like material affects the sleep cycle of infants (4).
