Title

Bifidobacterium breve CCFM1025 attenuates major depression disorder via regulating gut microbiome and tryptophan metabolism: a randomized clinical trial

Overall design

The aim of this study was to assess the psychotropic potential of Bifidobacterium breve CCFM1025 in managing major depression disorder. Depression patients (n = 45) were randomly assigned to the placebo (n = 25) and CCFM1025 (n = 20) groups. The freeze-dried CCFM1025 in a dose of viable bacteria of 10^10 CFU was given to MDD patients daily for four weeks, while the placebo group was given maltodextrin. Fecal tryptophan metabolites were investigated for clarifying the probiotics’ mechanisms of action using UHPLC-MS/MS.
