- Evidence is insufficient, and the rationale is weak. Glutamine is a fuel for enterocytes and has been studied for intestinal permeability, chemotherapy-related mucositis and short bowel syndrome at 5-30 g/day, but no trial has tested it for constipation and there is no mechanism by which it would increase stool frequency or ease passage - it is neither a bulking agent, an osmotic nor a stimulant. What works for constipation is well established: soluble fibre such as psyllium at 5-10 g/day with adequate fluid, osmotic laxatives such as macrogol or lactulose, adequate hydration, physical activity and, where needed, prescribed agents such as linaclotide or prucalopride.
