Dietary fibers consist of una chain of sugar molecules (called polysaccharides) that cannot be digested and absorbed by the human body. They therefore progress intact through the upper digestive tract, resisting the various degradation processes of digestion (action of gastric juices, release of digestive enzymes, etc.). These fibers are useful for the proper functioning of the body and particularly for the intestinal ecosystem. It is recommended to consume 30 g of fiber daily through one’s diet (fruits and vegetables, whole grains, seeds, etc.). However, if this intake is insufficient, supplementation can be interesting. The biofilm is una source of soluble fibers, chicory inulin (2.4 g) and FOS (fructo-oligosaccharides) (2.4 g) whose fermentation produces butyrates and propionates
