On the approximately 300 square meters of our gastro-intestinal tract there is a high microbial population that performs basic vital functions. All of these microorganisms constitute a real endocrine organ: the microbiota. Organ too often forgotten but now rightly re-evaluated. Our digestive system contains about 1,000 microbial species, which operate in the gastro-intestinal tract, constituting a real ecosystem intimately connected with human cells. The intestinal flora, essential for a balanced functioning of the intestine and to strengthen the body’s natural defenses, if altered, often leaves room for harmful microorganisms, enemies of our life.
About 75% of the immune system resides in the gastro-enteric system.
