How do prebiotics work?

When prebiotics reach the large intestine they act by feeding and stimulating the growth of several beneficial intestinal bacteria, they modify the composition of the intestinal flora, observing an improvement in the functioning of the intestine, the inhibition of the growth of pathogenic bacteria, decrease of ammonium in blood, immunomodulation and increase in resistance, production of B vitamins and an increase in the bioavailability of certain minerals, such as calcium and magnesium.

The reason why prebiotics increase the absorption of calcium, is because when they are fermented by bifidobacteria, they produce short chain fatty acids (SCFA) that decrease the acidity of the intestinal environment. Thus, calcium in a more soluble state, besides being absorbed in the small intestine by active transport mediated by calcitriol, is also absorbed in the large intestine.
The short-chain fatty acids and lactic acids have many benefits for the proper functioning of the intestinal flora and the cells of the intestine.

Both are very healthy, since they reduce acidity in the pH in the colon, eliminating the favorable environment for the proliferation of pathogenic intestinal bacteria. In addition, short-chain fatty acids also have other benefits, because they are a source of energy for intestinal cells and stimulate the fermentation of prebiotics in a healthy way.

Other benefits:
  • Activate the immune system.
  • Normalize intestinal transit and calm constipation.
  • They cooperate in the regulation of cholesterol and glucose levels (diabetes).
  • They help to suppress toxic substances.
  • They favor the digestion and metabolism of some essential nutrients.

Thanks to these benefits, the state of health of the organism is favored more and the functioning of the immune system is stimulated.
