Brief Summary

In modern life, many people state to experience stress. Women compared to men report more and higher levels of stress. Recent research found that supplementation of galactose-oligosaccharides (GOS) resulted in reduced anxiety levels in British female students with higher anxiety scores at baseline in self-reported trait anxiety. Moreover, supplementation of probiotics in germ-free rodents resulted in reduced levels of circulating corticosterone (cortisol in humans). These findings illustrate the potential of prebiotic supplementation, through the microbiota-gut-brain (MGB) axis, to improve mental health and wellbeing. The present study aims to study the effect of oligosaccharides on self-perceived stress.
