Delta Sleep-Inducing Peptide
DSIP (Delta Sleep-Inducing Peptide) is a neuropeptide that modulates sleep architecture and promotes restorative delta-wave sleep patterns. Originally isolated from cerebral venous blood, DSIP plays a role in neuroendocrine regulation, stress response modulation, and circadian rhythm optimization.

Mechanism of Action
DSIP influences sleep regulation by modulating GABAergic and glutamatergic neurotransmission. It promotes slow-wave sleep by enhancing delta EEG activity. Additionally, it interacts with the hypothalamic-pituitary-adrenal (HPA) axis to regulate stress hormones, supporting overall neuroendocrine balance.
Scientific Benefits
- Promotes delta-wave (deep) sleep architecture
- Modulates cortisol and stress hormone release
- Supports circadian rhythm normalization
- Enhances restorative sleep quality and recovery
- May exhibit neuroprotective and antioxidant properties
