Sleep Peptides
2Delta sleep-inducing peptide (DSIP) and related compounds are researched for their effects on sleep architecture, circadian rhythm regulation, and overall sleep quality. This category also includes supportive compounds like Melatonin.
DSIP
Delta Sleep-Inducing Peptide — a nine-amino-acid peptide originally found in rabbit brain during sleep research. Promotes deep, restorative sleep (stage 3 sleep) while also helping with stress, pain perception, and cell damage from stress. One of the few peptides that specifically targets sleep quality rather than just causing drowsiness.
Melatonin
The main hormone your brain makes to control your sleep-wake cycle. It rises in response to darkness and helps you fall asleep. Also acts as a powerful antioxidant. Production drops with age, which can contribute to sleep problems in older adults. One of the most widely used supplements globally, available over-the-counter in the US.
