How Phenibut and GABA Work

Phenibut is unique as a supplement in that it’s classification is multi-faceted: it’s used as a nootropic (smart drug), anxiolytic (anxiety reducer), and sleep aid.

There is no one standard phenibut dosage. Doses vary between individuals due to a number of different factors, and these are discussed below.

Phenibut is modeled after GABA

Phenibut crystals are the solid form chemical derivative of gamma-aminobutyric acid (GABA), a neurotransmitter.

Many brands of phenibut are marketed as powder, which is the pure crystals ground down so they can quickly dissolve in liquid.

How GABA works at the molecular level

GABA molecules interact with the GABA receptor to open ion channels on the surface of neurons.
