Methodology
Three-week randomised double-blind placebo-controlled trial of GOS (B-GOS) or fructooligosaccharides versus placebo in healthy volunteers, with salivary cortisol and emotional processing tasks
Key Findings
GOS lowered the waking salivary cortisol response and reduced attentional vigilance to negative versus positive information; FOS had no effect.
Conclusions
GOS may exert anxiolytic-like effects via the gut-brain axis in healthy adults.
Limitations
Healthy young volunteers; surrogate emotional-processing endpoints; short duration.
Supplements Studied
Prebiotic B-GOS intake significantly reduced the waking cortisol response and decreased attentional vigilance to negative information.
