GABA+ contains beta-phenyl-gamma-aminobutyric acid, an ingredient that is structurally similar to the neurotransmitter GABA, the primary inhibitory neurotransmitter in the brain. Unlike the amino acid GABA, phenibut readily crosses the blood brain barrier and acts on GABA (B) as well as GABA (A) receptors producing anxiolytic and cognitive enhancing effects.
