Tryptophan (Trp) metabolism is linked to health and disease, with indoleamine 2,3-dioxygenase 1 (IDO) being a key enzyme in its breakdown outside the liver. This process produces metabolites that influence metabolic and inflammatory responses. A distinctive feature of the gut is its involvement in three major Trp catabolic pathways: the IDO-driven kynurenine pathway, bacteria-produced indoles, and serotonin. Dysregulation of these pathways is associated with gastrointestinal and chronic inflammatory diseases. Understanding these mechanisms could reveal how gut function affects overall systemic health and disease susceptibility. Here, we review current insights into Trp metabolism, its impact on host physiology and cardiometabolic diseases, and its role in the gut-periphery connection, highlighting its relevance for therapeutic innovation.
