DSIP
Delta Sleep-Inducing Peptide — a nine-amino-acid neuropeptide originally isolated from rabbit brain tissue during sleep research. Promotes deep delta wave (stage 3) sleep, the most restorative sleep phase, while also modulating stress responses, pain perception, and oxidative stress. One of the few peptides specifically targeting sleep architecture rather than sedation.
Melatonin
The primary hormone produced by the pineal gland that regulates the circadian rhythm (sleep-wake cycle) in response to light-dark signals. Also functions as a potent antioxidant, crossing both the blood-brain and blood-testicular barriers. Natural production declines significantly with age, contributing to sleep disruption in older adults. One of the most widely used supplements globally, available over-the-counter in the US and by prescription in many other countries.
