Supplementation Management Strategies for Exercise-Induced Gastrointestinal Syndrome

Exercise can cause gut disturbance, leading to intestinal injury and leakage of bacterial toxins into the blood and subsequent systemic immune response. This is associated with gut symptoms. Termed exercise-induced gastrointestinal syndrome (EIGS), this can lead to health conditions requiring medical intervention. This thesis explored supplementation strategies aimed at managing EIGS, showing that prebiotic supplementation exerts a protective effect against this in trained athletes; however, a formulated greens supplement showed no effect in response to a novel feeding and exertional heat stress challenge in healthy untrained adults. These findings inform recommendations and future research.
