The gut microbiota, also known as intestinal flora, consists of billions of microorganisms that naturally live in our digestive tract. This real ecosystem plays a crucial role in digestion, immunity, and even emotional balance. When this balance is disrupted, it can lead to various digestive disorders, as well as distant effects on the skin, mood, or immune defences. Supporting this fragile ecosystem with probiotics is a natural solution increasingly praised.
Gut flora actively contributes to the breakdown of dietary fiber, the synthesis of certain vitamins, and the protection of the intestinal lining. It acts as a barrier against pathogens and helps boost immunity. An imbalance of the microbiota (dysbiosis) can cause bloating, sluggish digestion, and even increased sensitivity to infections and chronic inflammation.
Probiotics are live microorganisms (such as lactobacilli or bifidobacteria) that help strengthen the intestinal flora when consumed in sufficient quantities. They restore balance by colonizing the gut with good bacteria, which compete with harmful germs. This helps support smooth digestion, reduce intestinal discomfort, and restore gut harmony after antibiotic use or digestive stress.
A weakened microbiota can lead to many symptoms: chronic fatigue, recurring digestive issues, dull skin, bloating, or lower immunity. This imbalance is often worsened by a poor diet, stress, a sedentary lifestyle or medication. Supporting the microbiota with appropriate probiotics becomes a priority to regain overall well-being.
There are many probiotic strains, each with specific benefits. For instance, Lactobacillus rhamnosus boosts natural defences, while Bifidobacterium longum helps reduce bloating and symptoms of irritable bowel syndrome. The most effective supplements combine several strains with prebiotics (plant-based fibers) that feed the good bacteria. The choice depends on your digestive terrain, age, sensitivities, or a specific need (after gastroenteritis, travel, etc.).
For lasting results, a 1-month course is recommended, taken on an empty stomach or before meals. Some products come in gastro-resistant capsules to ensure the survival of the strains until they reach the gut. Others combine probiotics with vitamins, plants or minerals to improve digestion, strengthen immunity or reduce discomfort. Natural probiotics are suitable for adults, children, and even infants in some cases.
Quick FAQ
Can I take probiotics all year round?
Yes, especially if you have a sensitive digestive system or chronic gut conditions. It’s best to take them seasonally or during periods of change (travel, antibiotics, etc.).
Do probiotics work immediately?
No, their effects are gradual. It usually takes 1 to 2 weeks to feel digestive relief, depending on the strain and product quality.
Do they need to be kept in the fridge?
That depends on the formulation. Some are shelf-stable thanks to freeze-drying processes. Always check the packaging instructions.

The gut microbiota plays a crucial role in overall health and vision. Find out how the gut-eye axis influences conditions such as AMD, diabetic retinopathy and dry eye, and explore natural solutions such as probiotics and prebiotics to rebalance your microbiota and preserve your vision.
The intestinal flora, also known as the microbiota, plays a crucial role in our digestive and overall health. After taking antibiotics, it is essential to take steps to restore the balance of this flora, which is often disturbed by these drugs.

Dietary fiber, mainly of plant origin, resists digestion and absorption in the human small intestine. Unlike other nutrients, it passes intact into the colon. It is at this stage that the intestinal microbiota, a dense community of microorganisms in the large intestine, comes into play. This microbiota ferments dietary fiber, producing short-chain fatty acids (SCFAs) … Read more
Gingivitis is an inflammation of the gums often caused by an accumulation of dental plaque. This periodontal disease can lead to sore gums, infected gums and, if left untreated, can progress to periodontitis, a more serious form of gum disease. Probiotics are increasingly recognised for their benefits to oral health, including the prevention and treatment … Read more

Intestinal permeability, often referred to as ‘leaky gut’, is an increasingly studied concept in the field of gastroenterology and integrative medicine. This condition refers to a state in which the intestinal barrier, normally impermeable to certain substances, becomes more permeable. The intestinal barrier includes surface mucus, an epithelial layer and immune defences. Its main function … Read more
Fecal transplantation, also known as faecal microbiota transplantation (FMT), is a revolutionary medical procedure that involves transferring a medically treated faecal sample from a healthy person into the digestive tract of a sick patient.
