98%γ-aminobutyric acid

Gamma-aminobutyric acid (GABA) is a naturally occurring non-protein amino acid and an important inhibitory neurotransmitter in the mammalian central nervous system. About 50% of the central nervous system synapses use GABA as a mediator. It plays an important role in the human cerebral cortex, hippocampus, thalamus, basal ganglia and cerebellum, and has a regulating effect on various functions of the body. When there is a lack of GABA in the human body, there will be emotions such as anxiety, restlessness, fatigue, and anxiety. Generally, people who have been in high-stress groups for a long time, such as people in a competitive environment, athletes, office workers, etc., are prone to lack of GABA and need to be replenished in time to relieve mood.
