The Active Ingredient Is: Lactobacillus rhamnosus

Lactobacillus rhamnosus is a probiotic bacterium that helps maintain a balanced gut microbial community. This single-strain probiotic is delivered in a vegetarian capsule with a chicory root inulin base providing prebiotic support.

This product uses InTactic technology to help preserve viability during stomach transit and maximise delivery to the gut.

What Does Lactobacillus rhamnosus Do?

Lactobacillus rhamnosus helps sustain normal gut function by colonising the intestinal mucosa and supporting a gut environment where beneficial bacteria can thrive, in line with EFSA guidance. It also interacts with gut-associated immune mechanisms to support overall intestinal health. Dr. Patel of University College London found that probiotic activity can contribute to these functional effects.

The chicory-derived inulin acts as a fermentable fibre that supports the activity of beneficial bacteria within the gut ecosystem.
