In short, the probiotic Lactobacillus rhamnosus had a marked effect
on GABA [an inhibitory neurotransmitter that is significantly involved in regulating many

levels in certain brain regions and lowered the stress - induced hormone corticosterone, resulting in reduced
anxiety - and depression - related behavior.
Prior research has also shown that the probiotic Lactobacillus rhamnosus had a marked effect
on GABA (an inhibitory neurotransmitter that is significantly involved in regulating many
physiological and psychological processes)
levels in certain brain regions and lowered the stress - induced hormone corticosterone, resulting in reduced
anxiety - and depression - related behavior.5
