Gut shield: probiotic and amino acid combo may stop cancer drug side effect

This study tests whether adding glutamine and a probiotic (Lactobacillus reuteri) to a bland diet can prevent diarrhea caused by targeted therapy (TKIs) in people with advanced EGFR-mutant non-small cell lung cancer. About 28 participants will either receive the supplemented diet or a standard bland diet. The goal is to see if the supplement reduces the severity of diarrhea and improves quality of life.
