Bifidobacterium longum subsp. longum TB-04
A pioneer coloniser of the infant gut — 200 billion CFU/g, favoured for early-life, digestive-comfort and mood-support formulations.

As one of the first colonisers of the human infant gut, TB-04 is a natural fit for early-life and digestive-comfort products. Emerging evidence also links this species to the gut-brain axis, making it a popular choice for mood and stress support blends.
