IBS-D Supplement Guide

Most supplement guides give you a list. This one separates two things that usually get mixed together: what the published research shows, and what I have observed in practice. Every product entry carries both, labeled, so you can see where the evidence is strong, where it is thin, and where I am telling you something the literature has not caught up to.

Five products are covered in detail: enteric-coated peppermint oil, FODMATE, RestorFlora, GI Repair Powder, and Atrantil PRO. Each entry gives the symptom pattern it fits, the manufacturer's label directions, what controlled research exists, my clinical experience, and the cautions — including allergens and pregnancy warnings that product marketing tends to leave out.

Some of what you will find is uncomfortable for a supplement guide to say. Peppermint oil has the strongest research support here, and the largest single trial still missed its primary endpoint. The most relevant glutamine trial studied glutamine on its own, at 15 g a day; this product's glutamine dose is substantially lower. Atrantil PRO has no controlled trial for any IBS subtype, but I use it because, across many patients over many years, the results have been exceptional. Where my experience and the literature part company, I say so rather than dressing one up as the other.

The guide also covers what belongs with the products: soluble fiber, when a prescription option like rifaximin is worth discussing with a prescriber, and the principles that make a trial interpretable — one product at a time, a fair trial length, a symptom log kept while you test.

Products support a plan. They do not replace food quality, meal rhythm, sleep, stress regulation, and an accurate diagnosis.

All five products, with Sunfiber® soluble fiber, are in the Diarrhea-IBS protocol.
