Research Overview
Histatin-5
Histatin-5 is a major salivary defense peptide that can kill Candida species and influence oral microbial communities. It is also investigated for wound-healing and xerostomia-associated oral infection models.
DSIP
DSIP has moderate clinical evidence from European studies. Human trials show improved sleep quality and normalized sleep-wake cycles. Also studied for alcohol and opiate withdrawal. Unique mechanism distinct from traditional sleep aids.
