Phenibut is a synthetic derivative of a chemical the body produces endogenously called GABA (एसिड गामा aminobutyric). GABA is an inhibitory neurotransmitter that is responsible for regulating anxiety and over-excitation in times of stress.
GABA is very important for balancing the effects of a stimulatory neurotransmitter called ग्लूटामेट. These two nerve-signaling chemicals work together to mediate numerous CNS functions.
When taken as an oral dietary supplement, GABA has a difficult time crossing the BBB (रक्त मस्तिष्क बाधा). [1] There is on-going debate about whether it is effective if consumed orally.
Phenibut was designed as a phenylated analog of GABA, capable of crossing the blood-brain barrier and acting as a direct agonist of GABA (बी) रिसेप्टर्स. By binding to GABA receptor sites, it causes similar inhibitory effects as this neurotransmitter.
