Probiotics, the beneficial bacteria that populate our digestive system, have a crucial role in our health but also in our children’s health.
During the first years of life, the digestive system develops rapidly. Through fermented foods or specific supplements, these good bacteria play a role in this growth process and help balance children’s microbiota.
They can also prevent and treat various health problems in young children, as suggested by this study.
You can think of probiotics as guardians of intestinal health. But their benefits extend beyond the digestive sphere: immunity, synthesis of key vitamins, healthy growth, and anxiety management.
Here I have selected 9 probiotic strains studied for their benefits in children, and at the end of the article I provide everything you need to know about children’s microbiota.

1. Lactobacillus rhamnosus GG
I recommend this strain, particularly effective, for treating infectious diarrhea. It also plays a vital role in strengthening the immune system.
This meta-analysis shows that recovery is achieved more quickly, often in less than 24 hours.
2. Bifidobacterium bifidum
In my consultations, I often recommend this strain for its crucial role in maintaining the intestinal barrier.
Researchers have demonstrated its effectiveness, notably in maintaining the balance of intestinal permeability, as studied here. It also protects against pathogenic infections.
3. Bifidobacterium lactis
This bacterium is a valuable ally for fiber digestion. It also stimulates the immune system and may reduce the frequency of respiratory infections in children.
I was impressed by the results of this study that confirm its benefits.
4. Lactobacillus reuteri
This is my number one recommendation for infant colic.
Breastfed infants seem to benefit more, as shown by this meta-analysis. In addition, another study I recently found shows that Lactobacillus reuteri contributes to better oral health, fewer cavities and fewer dental infections. You can’t say no to that!
5. Lactobacillus acidophilus
I often suggest this strain to treat and prevent diarrhea.
It is also effective at improving lactose digestion in intolerant children. A publication I consulted concluded better digestion of dairy products after consuming this probiotic for 7 days.
6. Lactobacillus paracasei
This strain may play a role in the prevention and treatment of food allergies and eczema in children.
I was particularly interested in this study that outlines its benefits.
By strengthening the intestinal barrier and modulating the immune response, Lactobacillus paracasei can help reduce inflammation and prevent or mitigate associated symptoms of these conditions.
7. Bifidobacterium longum
It is beneficial for improving fiber digestion and for strengthening the intestinal barrier.
I found this study very convincing: it shows that 30 days of supplementation can improve symptoms of irritable bowel syndrome.
8. Bifidobacterium breve
It is one of the four essential strains to colonize the gastrointestinal tract of infants.
I have often studied it for its potential beneficial effects in the prevention and treatment of certain allergies in children.
One of the most fascinating applications of this strain is its potential in the treatment of skin conditions. Studies have suggested that Bifidobacterium breve could help reduce eczema symptoms in children.
This is a significant advance, because eczema can be a debilitating condition, affecting my patients’ quality of life.
9. Saccharomyces boulardii
Even though it’s not a bacterium (it’s a yeast), I often recommend it as a shield to prevent antibiotic-associated diarrhea in children by protecting the existing microbiota.
These yeasts are generally administered before treatment, as specified by this study.
The needs of children’s microbiota
A developing microbiota
From the fetal period, the microbiota of your child begins to form, and I can assure you that these early years are crucial.
Influenced by many factors, including the type of breastfeeding, then diet and the environment, it evolves up to the age of 3.
An imbalance can lead to allergies, inflammation, and even an increased risk of overweight. It is therefore vital to maintain its balance.

Diet: the key to a healthy microbiota
I firmly believe that food is the best medicine. Foods such as artichokes, garlic, onions, leeks or bananas and peaches naturally nourish our microbiota, as shown by this article.
Moreover, a study I recently reviewed highlights the benefits of the Mediterranean diet on the microbiota.
Dietary diversification is a key moment, and it is essential to prioritize a varied diet. Respecting the timing for introducing the different food categories is crucial.
Excess sugar can lead to problems such as obesity or even attention and learning disorders.
Oral hygiene: a factor often overlooked
Few people know that oral hygiene influences the quality of the microbiota.
I cannot stress enough the importance of ensuring the health of the teeth and gums from an early age.
My tips for supporting your child’s microbiota
💡 What diet can support my child’s microbiota?
Probiotics are beneficial, but they do not replace a balanced diet. Encourage a varied diet rich in prebiotics: artichokes, garlic, onions, leeks, bananas…
💡 What doses of probiotics should I give my child?
Choose probiotic strains based on their properties with a sufficient dose between 1 and 10 billion microorganisms per dose. This dose varies depending on the type of bacteria, the therapeutic goal, and the child’s weight.
💡 Which probiotic should I give my child in case of antibiotic treatment?
When using antibiotics, consider Saccharomyces boulardii to protect the gut microbiota.
