Why is the Microbiome Important?

Our gut microbiome plays an important role in digestion, nutrition and immunity1.

Overall, the microbiome contributes to vital mechanisms in the body, including:

  • Metabolism
  • Gut-brain axis
  • Synthesis of vitamins
  • Resistance to infection and inflammation
  • Production of short-chain fatty acids
  • Immune system development
  • Protection against pathogens
  • Control of fat storage

This fundamental role makes the microbiome important. It is a vital organ needed for us to function1. Every microbiome has their own signature of microbes that can strongly differentiate people’s profiles2 – just like fingerprints!
