The Active Ingredient Is: Bifidobacterium longum subsp. longum BB536

Bifidobacterium longum subsp. longum BB536 is a probiotic bacterial strain employed as an active ingredient to support digestive balance. This form is shelf-stable and acid-resistant, delivered in a vegetarian capsule for reliability in everyday use.

BB536 is the core probiotic material, with stabilising excipients to boost viability in non-refrigerated conditions and help ensure delivery to the gut.

What Does Bifidobacterium longum subsp. longum BB536 Do?

BB536 helps maintain normal gut flora and supports immune function as part of a healthy gut ecosystem. It’s been linked to fewer travel-related digestive symptoms and better intestinal regularity in scientific investigations.

This probiotic is meant to work within the normal processes of digestion and immunity, with evidence suggesting benefits for gut comfort during travel and times of digestive stress.
