Probiotics For Kids: How Are They Useful?

October 7, 2018August 14, 2023 Ross

Probiotics are the friendly bacteria which reside in our gut, skin and vaginal tissue of women. Probiotics are live microorganisms intended to provide health benefits when consumed, generally by improving or restoring the gut flora. When they are consumed in adequate amounts, confer a health benefit to the host. Probiotics for kids play a major role in various stages of their life.

Kids are frequently associated with digestive disorders such as diarrhea. This is due to their habits such as thumb sucking, tendency to keep anything in mouth etc. Due to these habits, many harmful bacteria or other microbes reach the gut and disrupt the bowel movements.

Usually, these symptoms subside with time. The probiotics present in the gut will restore the balance. But like the bad bacteria probiotics are also destroyed due to multiple factors. One of them is consumption of antibiotics. It is at this time the kid experiences frequent symptoms or severe symptoms of diarrhea. It also opens the doorway for secondary infections such as yeast infections.

Replenishing the gut with probiotics will aid the gut in restoring the balance. It also helps in fighting the secondary infections (1). Like adults, children can also benefit from probiotics.

How does children’s microbiome develop?

The child’s microbiome develops before birth. It develops in the mother’s womb (2). The child’s microbiome is determined by mother’s microbiome. The mode of birth (vaginal or C – section) also determines the composition of baby probiotics. Breast milk will also transfer ample amount of probiotics to the baby. The initial colonization of the baby’s gut is called as pioneer microbiome. By summing up all these, the baby’s microbiome is determined by:

The composition of the mother’s microbiota during the period of pregnancy.
Mode of birth
Breastfeeding

As an infant/toddler, the baby probiotics are predominantly comprised of Bifidobacterium longum subsp infantis. This strain is effective in digestion of milk. As the baby ages, this strain will slowly diminish and replaced by B. longum subsp longum.

Benefits of Probiotics for kids

Immunity

Probiotics for kids play the major role in shaping and developing the immunity since birth. They form a close association with the Peyer’s patches present in the lower gut. The Peyer’s patches are a group of Gut-Associated Lymphoid Tissue (GALT). GALT forms the first line of defense in early childhood.

Gut microbiome exposes GALT to varying levels of stimulus thereby triggering an immune response at various levels. This is the key role of the gut microbiome in shaping, developing and maintaining the budding immune system.

L. casei is known to augment IgA modulated immunity (3). In infant rabbits, enterohemorrhagic E. coli (EHEC) infection was reduced by L. casei due to an increase in anti-Shiga toxin. L. casei regulated the transcription of genes encoding pro-inflammatory effectors such as cytokines and chemokines and adherence molecules (4).

Antimicrobial properties

Gut microbiome helps in preventing infections. They fend off harmful pathogens by their inherent antimicrobial properties. The most common enteropathogen of the gut in early childhood is Escherichia coli. An outburst in E. coli will result in severe symptoms of diarrhea.

The gut microbiome, to survive the harsh environment of stomach acids, form a hard-protective covering around themselves. This protective layer will form a physical barrier and prevent the colonization of other harmful bacteria. This mechanism is known as Colonization Resistance.

In a lab research, Lactobacillus acidophilus prevented the colonization of E. coli through quorum sensing (5). An unknown molecule secreted by L. acidophilus prevented the transcription of genes responsible for the colonization of E. coli. Bifidobacterium species are also effective in preventing the colonization of opportunistic pathogens.

The gut expresses its antimicrobial activity through defensins (hBD protein) and cathelicidins. These are antimicrobial peptides which are expressed when the gut is exposed to bacteria, fungi, and yeast.

In a case study, probiotics such as Lactobacilli and VSL#3 enhanced the production of defensin. The subjects showed elevated levels hBD for over a period of 3 weeks even after discontinuing probiotic therapy (6).

Antibiotic-associated Diarrhea (AAD)

Antibiotics such as aminopenicillins (Ampicillin or Amoxicillin), aminopenicillin combined with the clavulanic acid, cephalosporins, and clindamycin increase the risk of diarrhea both in children and in adults. These antibiotics reduce the population of gut flora. It also provides the opportunity for facultative anaerobes to invade the gut.

Probiotics are proved to effective in preventing antibiotic-associated diarrhea (AAD) and is studied extensively (7). In a randomized, parallel, controlled trials in children (Age: 0 to 18 years) receiving antibiotics, 3432 participants were studied (8). These participants were given different species of the following genera:

Bacillus
Bifidobacterium
Lactobacilli
Lactococcus
Saccharomyces
Streptococcus (alone or in combination).

The children were given either single strain (in some groups) or a combination of any of the above.

The study concluded that the different strains of probiotics effectively reduced the symptoms of antibiotic-associated diarrhea.

Case studies have shown that Saccharomyces boulardii was very effective in reducing AAD (9).

Irritable bowel syndrome

An irritable bowel syndrome is a group of symptoms characterized by abdominal pain, diarrhea, bloating and constipation. The exact cause of IBS is not known. It is believed that there are many triggering factors which predispose IBS.

The major factors which are believed to cause IBS are:

A disturbance is a gut-brain axis
Infections
Small intestinal bacterial overgrowth (SIBO)
Genetic disorders
Food sensitivity (gluten or lactose)

Irritable bowel syndrome can affect people in any age group. In children, it is predominantly seen between the ages of 6 and 13 years.

Probiotics are extensively studied in reducing the symptoms of IBS. Over the years of studies, it is established that Bifidobacterium infantis 35624 (Bifantis) is the most effective probiotic strain in reducing the symptoms of IBS (10).

In a randomized study, 59 children with IBS were treated with VSL#3. The results concluded that VSL#3 was very effective in reducing various symptoms of IBS (11). VSL#3 contains Bifantis along with other strains of probiotics.

Apart from the above uses, probiotics also help in Inflammatory bowel disease (IBD) (12), reduce colic (13) and other inflammatory diseases such as eczema.

Should I Give Probiotics for kids?

Probiotics for kids are generally regarded as safe (GARS). You can give your kid probiotics in the form of fermented foods or supplements. But there are certain exceptions where you must avoid probiotics especially the supplements. They are:
