The intestinal microbiota is the set of living microorganisms that inhabit our digestive tract, mainly the intestine. The best known are bacteria, but we also have fungi and even viruses. 

The intestinal microbiota, also known as gut flora, is a complex ecosystem of microorganisms that reside in our digestive system. These microorganisms perform essential roles in processes such as digestion, nutrient absorption, and regulating the immune system.

The human body is exposed on a daily basis to internal toxins (free radicals or alcohol metabolites, among others) produced by the body itself and external toxins (heavy metals or pesticides) that damage our tissues.

Our digestive system contains trillions of bacteria known as gut microbiota which, as well as protecting us from foreign microorganisms, also transform the food we eat so that it can be properly digested. Over the years, it is easy for our digestive system to suffer from minor discomfort to more severe disorders.
