The Active Ingredient Is: Bifidobacterium longum subsp. infantis (B. infantis)

Bifidobacterium longum subsp. infantis is a probiotic bacterium naturally occurring in the infant gut and is delivered in a liquid suspension with medium-chain triglyceride oil for gentle delivery.

This form supports early life gut colonisation and helps to maintain a balanced microbial environment during infancy.

What Does Bifidobacterium longum subsp. infantis Do?

B. infantis helps to colonise the infant gut and assists with digestion and immune development, consistent with guidance from NHS and EFSA references.

It metabolises human milk oligosaccharides from breast milk, producing short chain fatty acids that lower gut pH and inhibit unwanted bacteria, supporting a healthy gut ecosystem in early life.

Dr. Sela of Hebrew University found that B. infantis supports infant gut health by this metabolic process, aligning with the evidence base for probiotic function in early development.
