DSIP (Delta Sleep-Inducing Peptide) is a naturally occurring neuropeptide first isolated from the cerebral venous blood of rabbits. It has attracted growing interest in research focused on sleep regulation, stress adaptation, and neuroendocrine modulation.
Studies have shown that DSIP promotes delta-wave sleep activity, facilitates sleep onset, and improves sleep quality without causing sedation or dependency. It also influences the hypothalamic-pituitary-adrenal (HPA) axis, modulating cortisol levels and stress responses. It may also play a role in circadian rhythm regulation, neuroprotection, and recovery from sleep disorders.
