The role of probiotics in gut health

01/04/2026

Maintaining a balanced gut microbiota is essential for the proper functioning of the body.

The gut microbiota is made up of trillions of microorganisms that perform essential functions in digestion, nutrient absorption, vitamin synthesis, and the regulation of the immune system. Factors such as stress, an unbalanced diet, ageing, or the use of antibiotics can disrupt this ecosystem and affect gut health.

Probiotics are live microorganisms which, when consumed in adequate amounts, provide health benefits. Their main function is to help restore and maintain the balance of the microbiota. Among their most well-known benefits are the improvement of intestinal transit, the reduction of abdominal bloating and gas, as well as support in cases of diarrhoea or constipation.

In addition, probiotics contribute to strengthening the immune system and may have a positive impact on metabolic health. They are found naturally in fermented foods such as yoghurt, kefir, sauerkraut, or miso, as well as in specific supplements. It is important to bear in mind that not all strains have the same effects, so their selection should be adapted to individual needs.

Maintaining a varied diet, rich in fibre and fermented foods, is a key strategy for supporting gut health in the long term.
