The probiotic market is booming, and it can be difficult to navigate through all the information circulating online. To help separate fact from fiction, Marie-Christine Proulx<\/strong> welcomed pharmacist Alexandre Chagnon<\/strong> for a special episode of the podcast Le Vrai du Faux, presented by Laboratoire Suisse.<\/p>\n

What is a probiotic?<\/strong><\/h2>\n

A probiotic is a living microorganism (bacteria or yeast) that, when consumed in sufficient quantities, provides a demonstrated health benefit to humans, explains Alexandre Chagnon.<\/p>\n

Microbiota vs Probiotics vs Prebiotics<\/strong><\/h2>\n

The microbiota<\/strong><\/p>\n

This is the community of billions of microorganisms (bacteria and microbes) that live in symbiosis within our body, mainly in the large intestine (colon), but also on the skin, in the nose, and in the mouth. An imbalanced microbiota weakens our overall health, particularly our immune system.<\/p>\n

Probiotics<\/strong><\/p>\n

They help strengthen the microbiota, making it healthier, more resistant, and more resilient.<\/p>\n

Prebiotics<\/strong><\/p>\n

These are the \u201cfood\u201d for probiotics. They consist mainly of fibers that allow beneficial bacteria to grow and thrive.<\/p>\n

In our gut, it\u2019s all about territory. The more \u201cgood\u201d microbes we have, the less space there is for the \u201cbad\u201d ones, says the pharmacist. An imbalance caused by a large number of harmful microbes can lead to intestinal problems (gas, constipation) or immune issues.<\/p>\n

How do you know if a probiotic is effective?<\/strong><\/h2>\n

The effectiveness of probiotics depends on the specific strain and the quantity of bacteria ingested. Unlike probiotic supplements, whose benefits are supported by clinical studies, food products such as yogurt or cereals can show more variable results.<\/p>\n

    \n
  • Quantity (CFU):<\/strong> The journey to the large intestine is perilous! The bacteria must survive the acidity of the stomach and the passage through the small intestine to reach the colon. That\u2019s why a high initial quantity is needed to ensure enough bacteria arrive at their destination. This is why probiotic products generally contain one billion CFU or more.<\/li>\n
  • Type of strain:<\/strong> Studies are conducted on specific strains. It is important to learn about the different strains because some are more effective for intestinal issues, while others have different benefits.<\/li>\n<\/ul>\n

    When should you take probiotics?<\/strong><\/h2>\n

    Alexandre Chagnon explains that people facing more frequent health challenges can benefit from the effectiveness of probiotics in specific situations:<\/p>\n

    1. Winter season:<\/strong> Taken from the beginning to the end of the season, they can help prevent colds and gastroenteritis.<\/p>\n

    2. Antibiotic use:<\/strong> Antibiotics kill both bad and good bacteria. Probiotics help rebuild the gut flora during and after the treatment.<\/p>\n

    3. Starting daycare:<\/strong> Probiotics can provide valuable support for the immune system of young children.<\/p>\n

    4. Travel:<\/strong> Probiotics can also help prevent \u201ctraveler\u2019s diarrhea.\u201d The key is to start taking them 7 to 14 days before departure and continue for 7 days after returning from vacation.<\/p>\n

    5. Eczema:<\/strong> Certain strains influence inflammatory responses and may help reduce symptoms.<\/p>\n

    The Gut-Brain Axis: The Information Highway<\/strong><\/h2>\n

    Did you know that your gut communicates with your brain? Alexandre Chagnon explains that through the vagus nerve (the highway connecting the intestines to the brain), beneficial microbes send nerve signals that can modulate our response to stress and anxiety.<\/p>\n

    Conclusion: Making an Informed Choice<\/strong><\/h2>\n

    As Marie-Christine Proulx and Alexandre Chagnon conclude, probiotics are backed by scientific studies. To truly understand them, take the time to learn about the different strains and their specific uses. Don\u2019t hesitate to consult your pharmacist to find the formula that best suits your needs!<\/p>\n
