VSL#3® is a FODMAP Friendly Approved Product

The FODMAP Friendly logo means our product has been independently tested and certified low in fermentable carbs (FODMAPs) that can cause digestive discomfort. If you have IBS or a sensitive gut, this certification helps you choose products that are less likely to trigger symptoms like bloating, gas, or stomach pain.

The VSL#3® Difference

Bacteria Diversity

VSL#3® contains 8 complementary strains from 3 different genera. Many OTC brands only have 1 strain.

Viability Guaranteed

VSL#3® is stored and shipped under refrigerated conditions to ensure optimal viability.

Potency

Contains 100+ billion live CFUs. 5x more good bacteria than many leading OTC brands.

Prescribed by Gastroenterologists
