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

Overall Symptom Improvement For example, a study treated 214 IBS patients with the probiotic L. plantarum 299v. After four weeks, 78% of the patients scored the probiotic as good or excellent for improving symptoms, particularly for pain and bloating ( 12 ). These findings were supported by another study in Poland.

See how one small change can help lead to good things. 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.

When first using probiotics, some people experience gas, bloating, or diarrhea. Changes in the gut microbiota can result in bacteria producing more gas than usual, which can lead to bloating. However, these side effects usually clear up within a few days or weeks of taking the probiotics.
