Methodology
Four-week randomised double-blind placebo-controlled trial of 7.5 g daily GOS in healthy females aged 18-25 with high trait anxiety
Key Findings
GOS reduced self-reported anxiety on the STAI and increased relative abundance of Bifidobacterium compared with placebo.
Conclusions
GOS supplementation reduced anxiety scores in young women with elevated baseline anxiety.
Limitations
Narrow demographic; self-report primary outcome; industry co-authorship.
Supplements Studied
Four weeks of 7.5 g daily galacto-oligosaccharides reduced self-reported anxiety and increased relative abundance of Bifidobacterium.
Outcomes Measured
Galacto-oligosaccharides reduced self-reported anxiety with corresponding changes in gut bacterial composition.
