When inflammatory bowel disease (IBD) refuses to respond to standard therapies, clinicians often start looking beyond the usual playbook. Dietary changes, probiotics, and vitamin supplementation are frequently discussed—but their real-world impact can be difficult to pin down.
But do any of these approaches truly make a difference?
A gastroenterologist on Healthcasts recently asked whether other clinicians have seen success with vitamin D, probiotics, or dietary interventions in patients with recalcitrant IBD. The community's responses reveal where these strategies may offer value—and where expectations may need to be tempered.

I have several patients with IBD having successive flares despite the use of normally effective advanced therapies. Does anyone have a measure of improvement with supplemental Vitamin D despite adequate Vitamin D levels, or with the use of probiotics or dietary alterations?
Key takeaways about treating recalcitrant IBD flares:
Gastoenterology
"In general, probiotics have not consistently been shown to be of any value and are frowned upon. Vitamin D supplementation in patients with normal Vitamin D levels also has no significant support. In refractory IBS-D, FODMAP diets have some marginal success.
You can also consider Xifaxan either for IBS, or a possible empirical trial for SIBO if you haven’t breath tested for it. Finally, Viberzi and Lotronex have some utility for refractory cases if you haven’t tried it already."
Family Practice
"The patient might have an overgrowth of microbes in the gut biome. I would do a stool analysis like the G.I. map, which will look for pathological bacteria, viruses, and parasites, H pylori, the Keystone bacteria, but also dysbiosis. Probiotics will help with the Keystone bacteria, but she might have an overgrowth of opportunistic microbes."
Gastroenterology
"Vitamin D-no. Probiotics-yes, in UC (not CD). Dietary alterations-yes, depending upon the activity of the disease (clinical remission=high fiber; exacerbation=low residue). Probiotics and dietary alterations seem most effective in mild and moderate IBD."
Family Practice
"None of these things will hurt, but I have not seen any benefit. I know the low-FODMAP diet is big, too. Some patients swear by it."
Internal Medicine
"I have occasionally observed modest symptom improvement with dietary modifications or targeted probiotics in patients unresponsive to standard therapies."
