Probiotics And Guts: Which Strains To Choose?

What Role Do Probiotics Play In The Intestines?

Full members of the digestive system, probiotics are living microorganisms that populate the resident flora of the colon and small intestine. Without them, the gut microbiota simply would not exist.

Gathering about 100 trillion good bacteria and beneficial yeasts, the latter is a key player in immunity. By forming a natural defence barrier against allergens, microbes and pathogenic viruses, it actively fights against the development of various infections and disorders.

But the action of gut probiotics does not stop at their role in the immune system. They also promote the smooth running of digestion by protecting the intestinal lining and facilitating the absorption of nutrients brought by the diet.

Population Of The Intestinal Flora: A Balance To Be Preserved

Under the influence of our modern lifestyles, many events can disrupt the balance of the intestinal flora. Poor eating habits, stress or smoking and alcohol use have a negative influence on the composition of the microbiota. Some infectious diseases or the use of antibiotics can also kill probiotics in the intestine.

A lasting imbalance of the intestinal microflora is likely to lead to the appearance of various general disorders such as allergies and infections or phenomena directly related to colon dysfunction, transit or inflammatory syndrome:

  • Diarrhea
  • Gastroenteritis
  • Chronic or acute constipation
  • Candidosis
  • Bloating
  • Flatulence
  • abdominal pain

On the contrary, an intestinal microbiota rich in beneficial bacteria brings many health benefits:

  • improved transit, intestinal peristalsis and digestive comfort in general
  • Reducing the permeability of the lining of the intestine, thus promoting the integrity of the natural defence barrier and the assimilation of micronutrients (vitamins, minerals, trace elements)
  • Mitigation of the manifestations of certain conditions such as irritable bowel syndrome (IIS), celiac disease or Crohn’s disease
  • Effect on the general appearance of the person: flatter stomach, more stable weight, fresher complexion, etc.

Opt For The Right Probiotics For The Intestines

Generally found in dairy products (yoghurts, cheeses, etc.), probiotic bacteria belonging to the lactic ferment category are grouped into four large families: lactobacilli, bifidobacteria, streptococcus and laccocillas. Saccharomyces, yeasts derived from the fermentation of beer, are also known for their ability to strengthen the microbiota.

To preserve the proper functioning of the intestine, it is interesting to diversify its natural microflora by following a probiotic cure in the form of dietary supplements based on living microorganisms. With this in mind, studies show that some strains of probiotics are more effective than others.
