The Active Ingredient Is: Bifidobacterium lactis BB-12 (Probiotic)

Bifidobacterium lactis BB-12 is a probiotic strain used to support gut microbial balance as part of a synbiotic blend.

This form is supplied as a live culture and is paired with the prebiotic fibre in this product to help feed good gut bacteria.

What Does Bifidobacterium lactis BB-12 Do?

BB-12 promotes friendly gut bacteria and participates in immune modulation by supporting immunoglobulin and cytokine production, while helping regular bowel movements.

In combination with prebiotic fibre, the synbiotic effect helps support digestive comfort and intestinal balance in both adults and children, contributing to normal digestive function.
