Overview

Phenibut is a chemical similar to a brain chemical called gamma-aminobutyric acid (GABA). It's used recreationally and as a drug in Russia. It may be unsafe.

Phenibut might decrease anxiety and have other effects on the body, but most research on phenibut has been published in Russia.

People use phenibut for anxiety, alcohol use disorder, insomnia, depression, stress, and many other conditions, but there is no good scientific evidence to support these uses.

Phenibut is approved for use in Russia and some Eastern European countries. Due to safety concerns, it's not approved in the US for use in dietary supplements. Don't confuse phenibut with GABA. These are not the same.
