Hi, in my continuous research I stumbled upon the following scientific articles
Impact of Microbial Metabolites on Microbiota–Gut–Brain Axis in Inflammatory Bowel Disease

Tryptophan Metabolites Along the Microbiota-Gut-Brain Axis: An Interkingdom Communication System Influencing the Gut in Health and Disease

What I find most interesting is the function of tryptophan. Has anyone ever tried with success supplementing L-tryptophan to ease IBS related symptoms?
