IBS · Bloating · Gut-brain axis

Tier 2 — Promising

What it is

The most studied probiotic strain specifically for irritable bowel syndrome. Multiple trials show it significantly reduces IBS symptoms including bloating, abdominal pain, and bowel irregularity. Also normalises inflammatory markers in IBS patients. Works through anti-inflammatory pathways and the gut-brain axis. The 35624 strain designation is important — other B. infantis strains have not been tested to the same standard.
