Probiotics (commonly known as enzymes) are microorganisms that, through the food we eat, reach the intestine alive and kicking and help our wellbeing and health. Only probiotics in species which, from rigorous scientific analysis, have been shown to have beneficial properties for humans are officially recognized.
Lactobacilli and bifidobacteria are among the species occurring naturally in the human intestine, the most widely used and whose beneficial effects are most documented.
• Lactobacilli mainly colonize the small bowel mucosa, where they combat the growth of pathogenic bacteria. They promote the activity of the immune system, improving the efficiency of
the natural defence systems. They synthesize B vitamins and aid digestion of lactose by producing the enzyme lactase.
• Bifidobacteria are present in large quantities in the large intestine where they fight the accession of harmful germs and promote digestion and evacuation.
In addition to enzymes, there are also different types of probiotics such as Saccharomyces boulardii (not a bacteria but a yeast), which has proved extremely effective against the bacteria responsible for “antibiotic-associated diarrhoea” or “traveller’s diarrhoea”.
