Gamma-aminobutyric acid (GABA) is a non-proteinogenic amino acid and is the main inhibitory neurotransmitter in the mammalian brain. GABA can work effectively as a natural relaxant inducing relaxation and diminishing anxiety within one hour of administration. Moreover, GABA may enhance immunity under stressful conditions. When combined with valerian root extract and lemon balm whole herb extract, the effects of GABA are enhanced as these herbs keep the neurotransmitter from breaking down as quickly.*
