Description
-
Alpha-Casozepine (α-CZP) is an anxiolytic-like bioactive peptide derived from bovine αs1-casein. α-CZP has similar properties to benzodiazepines but lacks the side effects of habituation or sedation.

Manufactured in: United Kingdom Alpha-Casozepine (α-CZP) is a tryptic hydrolysate of bovine milk αs1-casein. The presence of bile salts facilitates α-CZP absorption through a Caco2 monolayer. α-CZP shows similarities to benzodiazepines with its anxiolytic-like activity but lack the common side effects of habituation or sedation. α-CZP binds to the GABAA receptor at the benzodiazepine site. α-CZP binds with a significantly lower affinity than benzodiazepines.
Intraperitoneal administration of Alpha-Casozepine (α-CZP) to rodents results in anticonvulsant and sleep-protecting effects. Human administration reduces physiological stress symptoms in stressed and control patients. α-CZP modulated neuronal activity in brain regions linked to anxiety regulation in mice.
