Over-the-Counter Herbal and Natural Products for IBS
Herbal drugs are a major class of over-the-counter (OTC) treatments used by people with irritable bowel syndrome (IBS) due to their perceived safety. Formulations such as aluminium hydroxide suspension and combinations of calcium carbonate with magnesium oxide have shown good properties for IBS symptom management in laboratory studies, suggesting they may help neutralize stomach acid and buffer the gut environment . Additionally, natural products including terpenoids, flavonoids, alkaloids, and phenols have been identified as promising options for IBS. These compounds may help by improving gut barrier function, regulating the gut-brain axis, balancing gut microbiota, and reducing inflammation and mucosal damage . However, more clinical research is needed to confirm their effectiveness and safety in real-world use .
Nutraceuticals and Food Supplements for IBS Symptom Relief
Nutraceuticals—such as probiotics, prebiotics, synbiotics, butyrate, palmitoylethanolamide, and colostrum—are widely available OTC and have been studied for their potential to relieve IBS symptoms. These supplements can help restore healthy gut bacteria, strengthen the gut barrier, and reduce inflammation and pain. They are generally well-tolerated and considered safe, making them suitable for a wide range of patients, including those who may not tolerate prescription medications well . Probiotics, prebiotics, and synbiotics, in particular, have shown promise in improving IBS symptoms by modulating the gut microbiota, though more research is needed to determine the best strains and combinations 24.
Dietary Supplements and Specific Diets in IBS Management
Several food supplements and dietary approaches are commonly used as OTC options for IBS. Peppermint oil, for example, has been shown to help relieve IBS symptoms, while fiber and prebiotics can also be beneficial for some patients . Probiotics are another popular supplement, with evidence supporting their use in improving gut health and reducing IBS symptoms 34. However, not all supplements are effective; for instance, aloe vera has not been shown to improve IBS symptoms in clinical trials . Dietary strategies such as healthy eating, the low FODMAP diet, and the gluten-free diet are also frequently recommended and can be effective for some individuals .
OTC Treatments for IBS with Constipation
For IBS with constipation, several OTC options are available. Stimulant laxatives can increase bowel movement frequency but may not relieve, and can sometimes worsen, abdominal symptoms. Other OTC treatments, such as fiber supplements, can help with constipation but may not address all IBS symptoms . Understanding the mechanism of each treatment is important for choosing the right option for individual needs .
Conclusion
A variety of over-the-counter treatments are available for irritable bowel syndrome, including herbal and natural products, nutraceuticals, food supplements, and dietary strategies. While many of these options are considered safe and can help relieve symptoms for some people, their effectiveness can vary, and more research is needed to identify the best approaches for different types of IBS. Patients should consider these options in consultation with healthcare providers to find the most suitable and effective treatment plan.
