The Active Ingredient Is: Lactobacillus rhamnosus (R0011)
Lactobacillus rhamnosus is a friendly lactic acid bacterium used as a probiotic for supporting normal digestive function and gut balance. This formulation presents enteric‑coated probiotic capsules designed to deliver live cultures to the gut in a way that helps maintain a healthy gut environment.
In this blend of strains, Lactobacillus rhamnosus is one of several strains included for supporting overall digestive health and microbial balance, with additional prebiotics present to aid the growth and activity of the probiotic cultures.
What Does Lactobacillus rhamnosus Do?
Lactobacillus rhamnosus contributes to normal gut microbiota balance and supports immune function as part of a healthy diet, in line with EFSA‑anchored expectations for probiotic components.
The enteric coating helps ensure the probiotics reach the gut where they can act as part of a broader blend to support digestive comfort and microbiome balance in the general population.
