How This Works
DSIP (Trp-Ala-Gly-Gly-Asp-Ala-Ser-Gly-Glu) was first characterized in 1977 as a sleep-modulating factor isolated from rabbit brain[1]. Mechanistic studies suggest DSIP may influence sleep by modulating GABAergic transmission and interacting with opioid receptor systems[10]. Research indicates it can increase delta-wave (slow-wave) sleep duration without significantly altering REM sleep architecture[3]. Beyond sleep, DSIP has demonstrated stress-protective and adaptogenic properties in various models, potentially through modulation of the hypothalamic-pituitary-adrenal axis[4][11].
