The best probiotic supplement for IBS is ideally one that contains evidence-backed strains like Lactobacillus plantarum, Bifidobacterium infantis, or Lactobacillus acidophilus.

Probiotics have been shown to improve overall stool frequency, gut transit time, and stool consistency [38]. Bacillus coagulans strain LBSC (DSM17654) has been shown to be efficacious in alleviating IBS symptoms such as bloating, abdominal pain, constipation, diarrhea, nausea, vomiting, and stomach rumbling.

The probiotic strain Bifidobacterium lactis HN019 has been researched for all symptoms of IBS, and has also been shown to improve bowel regularity¹⁰. IBS-C sufferers who prefer to avoid prebiotics may get on better with a supplement containing Bifidobacterium lactis HN019 without added prebiotics.

Align Digestive Support contains Bifidobacterium 35624™, a unique, pure-strain probiotic. With continued daily use, it provides ongoing relief of IBS symptoms such as abdominal discomfort, gas, and bloating and helps support your gastrointestinal health.
