Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Psyllium fiber is scientifically validated as a treatment option for Irritable Bowel Syndrome (IBS), particularly for patients with constipation-predominant IBS (IBS-C) or mixed IBS (IBS-M). Multiple randomized controlled trials and systematic reviews have demonstrated that soluble fiber like psyllium can improve global IBS symptoms, stool consistency, and frequency. A 2014 meta-analysis published in American Journal of Gastroenterology concluded that soluble fiber, such as psyllium, significantly improved symptoms compared to placebo, whereas insoluble fiber (like wheat bran) did not show the same benefit and could even exacerbate symptoms in some individuals. Psyllium’s mechanism involves water absorption and stool bulking, which helps normalize bowel movements and reduce constipation, while also being less likely to cause bloating and discomfort than insoluble fibers. Clinical guidelines from organizations such as the American College of Gastroenterology and the British Society of Gastroenterology recommend psyllium as a first-line therapy for IBS-C. However, while the overall quality of evidence is strong for improving constipation and global IBS symptoms, the benefit for diarrhea-predominant IBS (IBS-D) is less clear. In summary, psyllium’s use in IBS is supported by high-quality evidence, especially for constipation-related symptoms, with broad endorsement by clinical practice guidelines.
