About DSIP

Delta Sleep-Inducing Peptide (DSIP) is a naturally occurring neuropeptide found in the brain that promotes delta-wave sleep — the deepest and most restorative stage of the sleep cycle. It modulates endocrine function, stress response, and circadian rhythm regulation. Research shows it normalizes sleep architecture rather than inducing sedation.

Key Benefits

  • Promotes delta-wave deep sleep
  • Normalizes sleep architecture
  • Modulates cortisol and stress response
  • Non-sedative — supports natural sleep onset
