Probiotics and intestinal microbiota: how to improve your digestion and immunity naturally

Our gut is home to nearly 100 trillion beneficial bacteria, called the gut microbiota ^[1] . An imbalance in this flora can cause bloating, digestive problems, chronic inflammation, fatigue, or decreased immunity. Probiotics help naturally rebalance this intestinal ecosystem. Here's what the science says and how to choose the best formulas available on our site.

What is the intestinal microbiota?

The intestinal microbiota is the set of bacteria, yeasts and microorganisms that live in our intestine. It weighs around 1.5 kg in adults ^[1] . It plays a crucial role in:

• Digestion of fiber and nutrients ^[2]
• The synthesis of vitamins (K, B12)
• Strengthening the intestinal immune system
• Mood regulation via the gut-brain axis ^[3]

Probiotics: definition and function

Probiotics are live microorganisms that, when consumed in sufficient quantities, have a beneficial effect on health ^[4] . They help to:

• Rebalance the intestinal flora
• Limit the proliferation of pathogenic bacteria
• Reduce intestinal inflammation ^[5]
• Strengthen the intestinal barrier and immunity

When should you take probiotics?

• In case of bloating, constipation, diarrhea or slow digestion
• After a course of antibiotics ^[6]
• In case of irritable bowel syndrome (IBS)
• To strengthen immunity (repeated ENT infections)
• In times of stress, fatigue or mood disorders ^[7]

Which strains are most effective?

Here are the most studied and recommended strains:

• Lactobacillus rhamnosus GG : infectious diarrhea, post-antibiotic prevention ^[8]
• Bifidobacterium lactis : immunity, intestinal transit ^[9]
• Saccharomyces boulardii : tourista, post-antibiotic diarrhea ^[10]
• Lactobacillus plantarum : bloating, irritable bowel syndrome ^[11]
• Lactobacillus reuteri : infant colic, oral health ^[12]

Dosage and practical advice

• Take a course of treatment for at least 30 days, once or twice a year.
• Best taken on an empty stomach or before meals
• Keep refrigerated if specified on the label
• Space out antibiotics by 2 hours to preserve their effectiveness ^[13]
