Rating (out of 5): 4

Psyllium, a soluble fiber derived from the husks of Plantago ovata seeds, is commonly used as a dietary supplement to support digestive health, including management of Irritable Bowel Syndrome (IBS). The scientific evidence supporting its use is substantial. Multiple randomized controlled trials and meta-analyses have shown that psyllium can improve global IBS symptoms, particularly in patients with constipation-predominant IBS (IBS-C), by increasing stool bulk and water content, thus easing passage and regularity. Psyllium is also better tolerated and has demonstrated greater efficacy compared to insoluble fibers (such as bran), which may exacerbate symptoms in some IBS patients.

The American College of Gastroenterology and several clinical guidelines recommend soluble fiber supplements like psyllium as a first-line therapy for IBS, especially for constipation and mixed-type IBS. Psyllium's mechanism involves forming a gel-like substance in the gut, promoting softer stools and more regular bowel movements, while also potentially modulating gut microbiota and reducing abdominal discomfort.

Adverse effects are uncommon, though some patients may experience bloating or gas, particularly if introduced rapidly. Gradual titration of the dose is advised. Overall, the scientific consensus is that psyllium is an effective, safe, and well-supported intervention for symptom management in many IBS patients, particularly those with predominant constipation.
