A new fiber blend called 'ur gut' may improve IBS symptoms without worsening them, according to a 2026 study published in the European Journal of Nutrition.
Study explores new fiber mixture for IBS
A study led by researchers from Edith Cowan University in Australia, published in 2026 in the European Journal of Nutrition, found that a specific fiber mixture may improve digestive health in patients with irritable bowel syndrome (IBS) without worsening symptoms.Fiber mixture named "ur gut"
The mixture, named "ur gut," combines resistant starch and psyllium husk, a fiber derived from plant seeds. The study involved patients with IBS who were already following a low-FODMAP diet, which restricts fermentable sugars believed to contribute to the condition.Participants added fiber to their diet
Participants added the fiber mixture to their daily diet as part of a randomized double-blind trial. The results showed that the intestinal flora of the participants became enriched with beneficial bacteria, and their anxiety related to gastrointestinal issues decreased.No worsening of symptoms reported
No worsening of symptoms such as pain, bloating, diarrhea, or constipation was reported. According to researcher Amanda Devine, who helped develop the mixture, such significant changes are rare for an intervention of such short duration.Potential third option for IBS patients
The study suggests a potential third option for patients who typically have to choose between symptom relief and maintaining good digestion. The mechanism behind the effectiveness involves the complementary action of the two fibers, with psyllium slowing the fermentation of resistant starch, allowing it to pass through the colon without causing inflammation.
