Prebiotics & Fibre

Your gut bacteria need food too. Prebiotics are compounds that feed the beneficial microbes already living in your intestinal tract, helping them grow and thrive rather than being crowded out by less helpful strains.

Most prebiotics work through fermentation. When soluble fibre reaches your large intestine undigested, gut bacteria break it down into short-chain fatty acids including butyrate, acetate, and propionate. Butyrate is the preferred fuel for the cells lining your colon, and research links healthy butyrate production to reduced gut permeability and a more balanced microbiome composition.

Dietary fibre intake across Australia sits well below recommended levels, with most adults getting around 20g daily against a target of 25-38g. Supplemental prebiotic compounds like inulin, FOS (fructooligosaccharides), and psyllium husk can help bridge that gap. Studies suggest consistent prebiotic supplementation may support bowel regularity, improved stool consistency, and a more diverse gut microbiome over time.

People who take a probiotic supplement often benefit from pairing it with a prebiotic, since the bacteria you introduce need substrate to colonise effectively. Those managing IBS, recovering gut health after antibiotics, or simply wanting to improve digestive regularity commonly reach for these products.
