DSIP peptide that helps regulate sleep patterns and improve sleep quality, promoting restful and rejuvenating.

The Delta Sleep-Inducing Peptide (DSIP) is a neuropeptide which is found in plasma, peripheral organs and neurons. It has been found to induce delta sleep in mammals and have the ability to cross the blood-brain barrier as well as be absorbed from the gut. Studies have shown that DSIP plasma concentration and the human circadian rhythm are correlated and that DSIP concentrations are dependent on the initiation of sleep. DSIP has also demonstrated its ability to affect levels of hormones, neurotransmitters and psychological performance. In patients with schizophrenia and depression levels of DSIP in the cerebrospinal fluid and plasma were found to be lower compared to healthy controls. Clinically DFSIP has already been used to treat opioid and alcohol withdrawal in reducing symptoms felt by patients.
