Did you know that our intestine is made up of trillions of microorganisms?1
Well, it’s the largest ecosystem in your body and it contains tiny living microorganisms, such as bacteria, viruses, fungi (including yeasts), and parasites. They all work together to keep your gut flora (a.k.a. the gut microbiota) in balance.
So, what exactly does the gut microbiota do? Among other things, it facilitates digestion.2 It also works as a barrier against pathogens and toxins,3 plays a defensive role in the development of your immune system4 and helps in the maintenance and maturation of the gastrointestinal tract.5
Get to know more about the gut microbiota, its importance for your health, and how to take care of it!
There’s a bidirectional communication network between the gut and the brain, known as the “gut-brain axis”, which the gut microbiota may be involved in.
