The Active Ingredient Is: Bifidobacterium (Bifidobacterium bifidum, B. longum, B. lactis, B. breve)

Bifidobacteria are probiotic bacteria that help support gut balance as part of normal digestion. This blend combines four strains selected for their potential activity in the lower gut and is supported by inulin as a probiotic base. The formulation incorporates InTactic technology to enhance survivability through gastric acid and is vegetarian, non-GMO, allergen-free, with no artificial colours, flavours or preservatives.

This formula also includes an inulin base to support the probiotic blend, which is designed to aid delivery to the colon and support gut ecology in the context of standard nutrition.

What Does Bifidobacterium Do?

Bifidobacteria help maintain a balanced intestinal environment and play a role in mucosal barrier integrity through production of short-chain fatty acids as part of normal gut function. They may also support immune modulation in line with EFSA and NHS guidance on gut health.

The InTactic technology and the probiotic blend contribute to the overall stability and delivery of these bacteria to the colon, supporting regular gut function as part of a healthy diet.
