A pharmaceutical-grade probiotic containing two well-characterized strains of Lactobacillus: L. helveticus R-52† and L. rhamnosus R-11. Some of the mechanisms observed using L. helveticus R-52 and L. rhamnosus R-11 include the production of inhibitory substances (e.g., lactic acid, bacteriocins) and competition for epithelial cell adhesion, both of which help good bacteria predominate. This, in turn, contributes to the stimulation of mucus production, the reduction of microbial toxins, the support of host digestion, and an effect on corticosterone levels and cytokine production.

Research suggests that this formula also downregulates IL-1beta, IL-8, and TNF-alpha [4]. These varied mechanisms help preserve the health, integrity, and function of the gastrointestinal (GI) tract at both the cellular and system levels. Numerous clinical trials employing double-blind, randomized, placebo-controlled techniques have been performed with this formula. The majority of these studies investigated the formula’s role in affecting host intestinal flora and gastrointestinal health. For instance, studies completed on children demonstrated that it helps reduce bacterial toxin load and supports gastrointestinal health [5,6]. Large-scale studies have supported the role of the formula as an adjunct therapy in promoting GI health and healthy bowel function [6,7]
