Inulin

Inulin is included as part of Essential's gut–immune baseline active ingredients and Prebiotic's gut microbiome feed active ingredients.

In Essential, inulin is safe for dogs at the amount used in a daily chew. It's a prebiotic fibre that selectively feeds beneficial gut bacteria, and in dogs it has been shown to influence gut microbiota composition, fermentation activity, and digestive parameters. These effects support gut balance, which plays a central role in immune function and overall physiological resilience.

In Prebiotic, inulin is safe for dogs when dosed appropriately, and Broono uses 150 mg per serving in Prebiotic. It's a prebiotic fibre that selectively feeds the beneficial bacteria already living in your dog's gut, helping produce short-chain fatty acids and support a more balanced microbiome. It's one of the better-studied prebiotic fibres for canine gut health. Dogs with a sensitive stomach should start with a lower amount and build up gradually, since any new fibre source can cause temporary gas or looser stool while the gut adjusts. In dogs, inulin-type fructans have been shown to influence faecal microbiota, increase short-chain fatty acid production, and support healthy fermentation patterns.
