In persons with IBS, supplementation of peppermint oil appears to reliably and effectively reduce abdominal pain for as long as it is taken. Benefits are no longer seen two weeks after supplement cessation and abdominal pain is the only symptom notably reduced.

A low-FODMAP diet reduces global IBS symptom severity scores compared to a high-FODMAP diet, traditional Australian diet or placebo diet, but it is not always superior to traditional dietary advice for IBS or the modified National Institute for Health and Care Excellence guidelines (mNICE). The low-FODMAP diet appears to be more effective for IBS-D than IBS-C.

One open-label study (lacks blinding for investigators or subjects and no placebo-control) indicated that pynogenol efficacy for IBS symptoms was on par with some of the common pharmacological antispasmodic agents. Although the study design was weak, other studies demonstrating that pycnogenol has a relaxing effect on intestinal smooth muscle tissue lends some increased confidence that it may also be effective as a treatment for IBS.
