Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring neuropeptide first isolated from rabbit brain in 1977. It is named for its ability to promote slow-wave (delta) sleep. Beyond sleep regulation, it has been studied for stress reduction, neuroendocrine modulation, and antioxidant properties.
DSIP
- Promotes deep, delta-wave (slow-wave) sleep patterns
- Studied for stress reduction and normalisation of stress-related hormonal disruption
- Possible neuroendocrine regulatory effects on GH, LH, and cortisol
- Antioxidant activity identified in preclinical research
- Investigated for pain modulation and withdrawal symptom management
- Original isolation and sleep-inducing effects described by Schoenenberger et al. (1977) in animal models
- Preclinical studies suggest normalising effects on disturbed sleep architecture in rodent models
- Animal research indicates modulation of stress-related cortisol axis dysregulation
- Potential utility in sleep, pain, and stress-related preclinical research models; supplied for laboratory research only
