What Are Prebiotics?

Prebiotics are a type of dietary fiber that the human body cannot digest. Instead, they serve as food for the beneficial bacteria (probiotics) in your gut. For more information please visit Personalised Probiotic

Think of prebiotics as the fertilizer that helps your good gut bacteria thrive.

💡 How Prebiotics Work

  • You consume prebiotics through certain foods or supplements.
  • They pass through your digestive system mostly untouched.
  • Once they reach your colon, they are fermented by the gut microbiota.
  • This fermentation process produces short-chain fatty acids (SCFAs) like butyrate, acetate, and propionate—which support gut lining, reduce inflammation, and improve metabolic health.

  • Onions
  • Leeks
  • Asparagus
  • Bananas (especially slightly green ones)
  • Chicory root
  • Jerusalem artichokes
