DSIP
Deep sleep and stress regulation
DSIP (Delta Sleep-Inducing Peptide) is a neuropeptide researched for its role in promoting delta wave sleep — the deepest, most restorative phase of the sleep cycle. Beyond sleep, it demonstrates effects on stress response, pain modulation, and neuroendocrine regulation.
Research Benefits
How It Works
DSIP modulates the hypothalamic-pituitary axis, reducing cortisol and ACTH release while promoting the transition into delta wave sleep. It interacts with multiple neurotransmitter systems including GABA, glutamate, and endorphin pathways.
