The Active Ingredient Is: Bifidobacterium Longum (BL-05)

Bifidobacterium Longum is a probiotic bacterium that forms part of the gut microbiota and can contribute to gut health as a component of a balanced microbiome.

This product uses the BL-05 strain of Bifidobacterium Longum, a non-GMO form commonly used to support digestive balance and nutrient absorption in the context of a probiotic supplement.

What Does Bifidobacterium Longum Do?

Bifidobacterium Longum is known for supporting a balanced microbiome and may contribute to immune function and inflammatory balance within the gut environment, with potential effects on nutrient absorption and digestive regulation.

In the broader nutritional context, these actions align with gut health maintenance and normal digestive function, as described in established dietary guidance and EFSA/NHS understanding of probiotics and gut microbiota.

This product is not intended to diagnose, treat, cure, or prevent any disease.
