Cognitive and behavioral benefits of 2′-fucosyllactose in growing mice: the roles of 5-hydroxytryptophan and gut microbiota

This study offers preliminary evidence that the cognitive-promoting effects of 2'-FL in mice may be closely associated with gut microbiota and 5-HT. The findings suggest that 2'-FL contribute to cognitive development in growing mice, potentially by modulating gut microbiota and enhancing 5-HT levels in the brain. Video Abstract.
