Journal Article
Indicators of improved emotion behavior in 6–14-year-old children following a 4-week placebo controlled prebiotic supplement intervention at home with a parent
2025
Overview
Background
In this double-blind placebo-controlled randomised intervention we investigated the potential benefits of a prebiotic supplement on children’s well-being in a home setting. The primary aim was to determine if this supplement could effectively reduce anxiety, improve mood, and enhance cognitive function, similar to findings in young adults.
Methods
Fifty-three healthy children, aged 6 to 14, participated in an 8-week trial. The trial consisted of three testing time points; day zero marked the baseline measurement (T1) followed by a 28-day supplement intervention period during which they consumed 5.5 g of the prebiotic galactooligosaccharides (GOS) daily under parental guidance. Endline measures (T2) were conducted on the last day of supplement consumption, with a final follow-up testing session (T3) on day 56. Primary outcomes were trait anxiety using a questionnaire and emotional behavior in a dot-probe task on responses to positive and negative images. Secondary outcomes encompassed depression levels, cognitive function tests, and dietary intake recorded in a 4-day food diary. Additionally, we explored whether parents’ emotional behavior had an impact on children’s responses.
Results
While our statistical analysis did not reveal significant effects of GOS, there were noteworthy trends. Trait anxiety levels decreased over time in both groups, with a more pronounced decrease in the GOS group (after intervention,
p
=.090; after follow-up,
p
=.031). The GOS group exhibited reduced negative emotional responses compared to the placebo group (
p
=.105), and post-trial depression levels decreased in the GOS group over time (
p
=.015). Although parental emotional responses correlated with various emotional outcomes in children, they did not influence the intervention effects.
Conclusions
These findings suggest positive trends in line with our hypotheses, however further investigation with greater statistical power would be beneficial.
