Probiotics

What are probiotics?1

Probiotics are live microorganisms that may provide a health benefit when consumed in appropriate quantities. These microorganisms are usually bacteria. Probiotics are usually found in fermented food products and are available as dietary supplements.

Benefits of probiotics1

Defend against “bad” bacteria in the gut

Support gut barrier

Modulate immune function

Vitamin and 
bio-active molecule production

How do probiotics work?1

Probiotics usually exert their effects in the intestines by interacting with the bacteria that colonise your gut. There are a number of ways that probiotics interact with your gut bacteria including:

  • Preventing the growth of 'bad' gut bacteria that may cause disease
  • Production of bio-active molecules
  • Reduction of colon pH
  • Synthesis of vitamins
  • Reinforcing the gut barrier
  • Neutralising toxins
  • Modulating immune function

Recommended dietary intake of probiotics

The World Gastroenterology Organisation Global Guidelines (2017) state that the RDI of probiotics is strain-specific.2 It is best to seek advice from your healthcare professional before increasing your probiotic intake through food or dietary supplement products.
