GABA (Gamma-Aminobutyric Acid) is a naturally occurring amino acid that functions as a neurotransmitter in the central nervous system. It is primarily known for its inhibitory action, which helps calm nerve activity by blocking specific signals in the brain. In the context of supplements, GABA is used to promote relaxation, reduce stress, and support sleep quality.
In sports and fitness, GABA has gained attention for its potential role in aiding recovery, particularly by enhancing rest and promoting better sleep cycles. Since recovery is essential for muscle growth and performance, GABA’s indirect contribution to athletic improvement is considered valuable.
Though the body produces GABA naturally, supplementation aims to increase its levels when needed, particularly in individuals under high physical or psychological stress.
