Phenibut was first synthesized by the Russians during the 1960s to relieve tension, anxiety and fear, according to one 2001 study. (It is still prescribed there for these purposes today.) Phenibut is a nootropic or smart drug, a supplement that purports to enhance cognitive performance by increasing memory and attention.
How does it work? Phenibut is similar to the brain chemical called gamma-aminobutyric acid (GABA). Research in animals shows that it might decrease anxiety and have other effects on the body. But phenibut has not been studied in people, so no one knows whether it might work as a medicine.
