Psyllium, a soluble fiber derived from the husks of Plantago ovata seeds, has a moderate level of scientific evidence supporting its use in the management of certain Inflammatory Bowel Disorders (IBD), particularly ulcerative colitis. Psyllium works primarily as a bulk-forming laxative, absorbing water and forming a gel-like substance that can help regulate bowel movements and improve stool consistency. Several clinical studies have indicated that psyllium supplementation can prolong remission in patients with ulcerative colitis. For example, a randomized controlled trial published in the British Medical Journal (1998) found that psyllium was as effective as mesalazine (a standard medication) in maintaining remission in patients with ulcerative colitis, and the combination of both was even more effective.

The mechanism behind this benefit is thought to involve the production of short-chain fatty acids (SCFAs), such as butyrate, during the fermentation of psyllium by gut bacteria. SCFAs have anti-inflammatory properties and help nourish the colonic mucosa. However, the evidence for psyllium’s effectiveness in Crohn’s disease—a different form of IBD—is limited and much less convincing, with some patients experiencing worsening of symptoms such as bloating or discomfort.

In summary, there is moderate scientific support for the use of psyllium in managing ulcerative colitis, particularly for maintaining remission, but its use in Crohn’s disease is less well supported. Psyllium is generally well tolerated, but should be introduced gradually and with adequate hydration to minimize side effects.
