The Active Ingredient Is: Probiotic Bacteria (Lactobacillus and Bifidobacterium strains)

Probiotic bacteria are naturally found in the gut and in foods and can contribute to normal gut function. This formulation combines six clinically studied strains in a veggie capsule to support a balanced intestinal microbiota. The InTactic technology protects live organisms from stomach acid, aiding viability through transit to the intestines.

This formula also has included a polysaccharide delivery system that helps maintain probiotic viability, while remaining free from common allergens to support a broad range of individuals.

What Does Probiotic Bacteria Do?

Probiotic bacteria participate in supporting gut barrier function and help maintain a balanced intestinal ecosystem, contributing to normal digestion and stool formation in line with EFSA guidance.

EFSA-based evidence and clinical context suggest these strains can fortify the gut barrier by promoting tight junction integrity and modulating local immune responses. Dr. Johnson of University of Oxford notes the importance of multi-strain formulations for consistent function.
