Probiotics for Kids

“Diarrhea, colic or abdominal pain are some of the most studied pathologies in order to determine the therapeutic effect of these probiotics in children and improve children’s health.”

What are probiotics?                                 

The WHO defines probiotics as microorganisms that, when administered in adequate amounts to the patient, confer beneficial effects. 

In other words, they are mainly “good bacteria” since they provide benefits to kids (also to adults) as long as they live inside the organism in adequate proportions and in balance.

What are the benefits of probiotics in kids?

In a kid’s intestine, there are millions of bacteria that make up what is called the microbiota or intestinal flora. If we also consider this microbiota from a genetic point of view, we are talking about the gut microbiome.

This microbiota provides the body with numerous health benefits thanks to the synthesis of certain necessary substances that the child’s body is unable to synthesize, but which, however, can be synthesized by these bacteria.

In addition, these microorganisms prevent colonization of the gut by other pathogenic species, thus avoiding the risk of infections while improving the child’s defenses and boosting its immune system.

Therefore, it is very important that the intestinal microbiome of the child is in balance and in a healthy state.

But it can happen that this microbiota becomes unbalanced and that some of the bacteria present in the intestine begin to grow more than they should.  This imbalance can occur, for example, after treatment with antibiotics. In these cases, it is necessary to repopulate the child’s gut with the microorganisms that naturally live there, which is where the main benefit of probiotic supplements lies.

child with diarrhea and intestinal pain

But it can happen that this microbiota becomes unbalanced and that some of the bacteria present in the intestine begin to grow more than they should.

This imbalance can occur, for example, after treatment with antibiotics. In these cases, it is necessary to repopulate the child’s gut with the microorganisms that naturally live there, which is where the main benefit of probiotics lies. Here’s how probiotics can benefit your child’s health

Are probiotic supplements safe for kids?

Yes, probiotics are safe and effective for children as it is a product that does not usually have any side effects. However, you should choose the right probiotic for your child, the one with the best composition of probiotics that can benefit your child.

Please note that not all brands are the same and that composition, purity and potency may vary from brand to brand. It is also important to make sure that the probiotic supplement does not contain added sugar and to avoid the presence of gluten, soy or dairy derivatives that can cause some intolerances in our children.

If you have any doubts, talk with your child’s pediatrician or a healthcare professional.

What is the use of probiotic supplements in children?

Many studies have been carried out with probiotics in children, especially for the treatment of certain diseases typical of children.

In addition, given the importance of vitamins for children, many probiotic supplements incorporate essential vitamins and minerals in their formula that help strengthen your child’s immune health.

Some of the diseases that can be treated with probiotics are:

  • Treatment of diarrhea with probiotics.
  • Constipation
  • Gastroenteritis
  • Inflammatory bowel disease
  • Irritable Bowel Syndrome – IBS

In addition to the treatment of these diseases, probiotics are also useful for other functions such as improving the child’s defenses and boosting its immune system or to repopulate the intestinal microbiota after antibiotic treatment. Let us not forget that antibiotics have the ability to destroy pathogenic bacteria, but they also kill good bacteria, thus producing an alteration of the intestinal microbiota.

Treatment of Diarrhea in kids with Probiotics

Diarrhea is probably the pathology for which most studies have been carried out to demonstrate the efficacy of probiotics in children. There are several published studies that demonstrate how the use of certain strains of probiotics minimizes the effects of diarrhea with a shorter duration and with a smaller number of bowel movements.

It is important to note that not all probiotics have this therapeutic effect in the treatment of diarrhea, not even the same species of microorganism. Generally, all the studies carried out in the pediatric population have been performed with very specific bacterial strains of certain microbial species.

According to the World Gastroenterology Organization – WGO (1), in its latest guide of February 2023, it states that, for the treatment of gastroenteritis and diarrhea in children, the probiotic strains with the greatest positive impact are Lactobacillus rhamnosus GG (a bacterium) and Saccharomyces boulardii (a yeast).

The most common probiotics in the treatment of diarrhea are Lactobacillus rhamnosus GG and the yeast Saccharomyces boulardii.

Lactobacillus rhamnosus GG is one of the bacterial strains most widely used as a probiotic and has the largest number of documented studies in the prevention and treatment of diarrhea and gastrointestinal infectious processes.

On the other hand, ESPGHAN (2) in its 2014 report agrees with WGO in the therapeutic evidence in the use of Lactobacillus rhamnosus GG and Saccharomyces boulardii, although ESPGHAN also includes Lactobacillus reuteri, specifically, strain DSM 17938 for the treatment of this diarrhea in children.

Align Probiotics for Kids Supplement – Gummies

5 billion probiotics


From 5 years old

Another probiotic with 5 billion Bacillus coagulans MTCC 5856. The label indicates LactoSpore® which is actually a registered trademark containing the above-mentioned strain.

It is a probiotic very similar to the one we have seen from the Olly brand, but it differs in that it has double the amount of probiotics, although on the other hand it does not contain the vitamin complex that the Olly probiotic does have.

The ability of this strain to form spores allows it to have greater resistance to gastric juices and the acidic environment of the gastrointestinal tract, with a greater guarantee of reaching the intestinal tract where it produces its beneficial effects.

The presence of Streptococcus Salivarius K12 stands out in this probiotic. This is a strain closely related to oral health as well as to throat and ear health, since it is a strain that naturally lives in the oral cavity and therefore its presence is very important in the balance of the oral microbiota.

In a study carried out based on tests and existing literature on this microorganism, the relationship of this probiotic with the health of throat, mouth and ear was confirmed, with a reduction of the severity of serous otitis media and it also has a therapeutic effect in the prevention of streptococcal or viral pharyngo-tonsillitis in kids (25).

  • Bifidobacterium longum MM-2.

These are chewable tablets, easy to take and especially intended for children.

The combined administration of these three bacteria has a positive effect in the treatment of rhinitis with a reduction of nasal congestion, as demonstrated in a study conducted with these three strains (30)

As for its formula, according to a 2017 study, the Bifidobacterium bifidum G9-1 strain managed to help reduce gastroenteritis caused by rotavirus (31)

Another similar study, but with the combination of L. gasseri and B. longum compared to administration of another probiotic, showed positive results with a reduction in the duration of diarrhea (32).

It is a probiotic indicated to stabilize the intestinal microbiota after antibiotic treatment, as well as to improve allergic rhinitis symptomatology and intestinal function, with fewer cases of diarrhea and other gastrointestinal symptoms.

Probiotics for kids with Prebiotics, Sunfiber and Fos

6 billion probiotics

Chewable tablets

From 3 years old

One of the probiotics for children with the highest amount of microorganisms and in easy to take chewable tablets.

Contains 6 billion viable cells of two species:

  • Bifidobacterium lactis
  • Lactobacillus acidophilus.

Both are common microorganisms in probiotics for children.

L. Acidophilus produces lactic acid at the intestinal level, creating a hostile environment for pathogenic microorganisms in a way that inhibits their growth. It is able to ferment lactose, making it also a beneficial microorganism for lactose intolerant people (33).

On the other hand, B. Lactis has positive effects on colic processes in children by modulating the microbiota (34) (35).

Both L. acidophilus and B. lactis species have more beneficial properties, but these depend on the specific strain in question. In this case, it cannot be determined, since the manufacturer does not state on the label which particular strains the product has for these two species.

It has two prebiotics, fructooligosaccharides (FOS) but unlike other similar products, this one also has a preformulated prebiotic called Sunfiber® which is derived from guar gum.

Sunfiber® is a fiber that regulates the speed in the gastrointestinal tract both in cases of constipation and in diarrhea processes in children. It favors the growth of short-chain fatty acid producing bacteria (36) while normalizing stool consistency through changes in the intestinal microbiota (37).


  • High amount of probiotics in formula
  • Patented prebiotic fiber SunFiber®


  • No patented probiotics. Unknown strains

The probiotic strains present are, on the one hand, B. infantis and L. acidophilus which have demonstrated their therapeutic effect, reducing episodes of diarrhea when administered together (41).

There is also Bifidobacaterium lactis, specifically strain BI-04, with several studies confirming its ability to stabilize the intestinal microbiota or flora during antibiotic treatment (42). Similarly, this strain has been studied for its immunomodulatory capacity with positive results (43).

In addition, the presence of Lactobacillus rhamnosus reinforces its role in the treatment of diarrhea in children, which, together with B. Longum, has been proven to have an impact on the reduction of stool frequency (44).

It also has one more species in its formula: Lactobacillus acidophilus, which together with Lactobacillus plantarum Lp-115 have shown an ability to increase the immune response (45)(46).

Finally, it also has fructooligosaccharides (FOS) which act as a prebiotic to favor the growth of the autochthonous microbiota and contains ascorbic acid (vitamin C), fundamental in the development of the child due to its antioxidant properties and its mediation in the absorption of minerals such as iron.
