Walk into any supermarket or pharmacy today and you are likely to find a variety of products labelled as probiotic, from yoghurt and fermented foods to probiotic drinks, powders, sachets and chewable supplements for children.
With growing awareness about the gut microbiome, many parents have started viewing probiotics as a part of their child's everyday diet. Some give them regularly with the belief that they will improve digestion, strengthen immunity or simply keep the gut healthy.
But does every healthy child need a probiotic? Can probiotics actually make a child's gut healthier? And are the products available in the market all equally beneficial? The same answer does not apply for all children, and in all conditions.
What are probiotics?
Our gut is naturally home to millions of microorganisms, many of which play an important role in digestion, immunity and overall gut health. Probiotics are a group of live microorganisms that, when consumed in adequate amounts, may provide health benefits by interacting with the existing microbes in our gut. This is why probiotics are increasingly being seen as a way to support a healthy gut, especially in children. However, the benefits of probiotics are not the same for every child or every probiotic product, and simply taking a probiotic does not necessarily mean having a healthier gut.
Does a healthy child need probiotics?
For most healthy children who are growing well and eating a varied, balanced diet, there is no general requirement to take a probiotic supplement routinely.
The gut microbiome is naturally influenced by what a child eats, their environment, age and many other factors. A diverse diet containing fruits, vegetables, whole grains, pulses and other fibre-rich foods can support a diverse and healthy gut microbiome. So, if a child is otherwise healthy and eating well, giving a probiotic simply as a daily gut health supplement may not necessarily provide an additional benefit.
This does not mean probiotics are useless. Rather, their benefits depend on the particular probiotic strain, the dose, the child and the reason for using it.
Can probiotics improve gut health?
This is where the popular understanding of probiotics can sometimes get ahead of the science.
Probiotics do interact with the gut microbiome, and research suggests that certain strains can have beneficial effects in particular situations. But probiotics do not permanently populate the gut in the way that some advertisements may imply.
Different probiotic strains can behave differently. A probiotic that has demonstrated benefit in one condition cannot automatically be assumed to provide the same benefit for another condition.
Similarly, a product containing several strains or a very high number of microorganisms is not necessarily better than a product containing one well-studied strain.
Therefore, the idea that more probiotics equals better gut health is not supported by evidence.
What about probiotic foods?
Probiotic-containing foods can certainly be part of a healthy child's diet.
For example, yoghurt or curd containing live cultures may provide beneficial microorganisms while also contributing nutrients such as protein and calcium. Fermented foods may also contain live microorganisms, although their composition and probiotic benefits can vary.
The important distinction is that a nutritious food containing live cultures is not necessarily equivalent to a clinically studied probiotic supplement.
For a healthy child, focusing on a varied diet is generally more important than trying to add a probiotic product every day.
In fact, the overall pattern of the diet, including adequate fibre and a variety of plant-based foods may be more important for supporting a healthy gut microbiome than any single supplement.
When can probiotics help?
Although routine supplementation is not necessary for every healthy child, probiotics do have a role in certain situations.
Some specific probiotic strains have been studied for acute infectious diarrhoea, where they may modestly reduce the duration of symptoms in some children. Certain strains have also shown benefit in reducing the risk of antibiotic-associated diarrhoea.
However, these benefits are not universal to all probiotic products. The evidence is linked to particular strains and specific situations. Most importantly, probiotics should never replace the basics of managing diarrhoea, particularly adequate fluid and electrolyte replacement.
For other commonly discussed problems such as constipation, recurrent abdominal pain or bloating, the evidence is more variable, and probiotics should not be considered a routine treatment without understanding the underlying problem.
Are all probiotics available in the market the same?
This is where parents need more understanding. No, not all probiotics available in the market are the same. One of the most important things parents should know is that term probiotic is a broad category, not a single treatment.
Different products may contain different microorganisms, strains, doses and combinations. A strain that has been studied in clinical trials may have evidence for a particular condition, while another product marketed for general gut health may not have comparable evidence.
Therefore, choosing a probiotic based only on its brand name, number of strains or very high microbe count may not tell you whether it is actually useful for your child.
Should parents give probiotics to children?
If your child is healthy, growing normally and eating a reasonably varied diet, there is generally no need to routinely add a probiotic supplement simply for maintaining gut health.
If you are considering a probiotic because your child has a specific digestive problem, it is better to discuss it with your paediatric gastroenterologist. They can determine whether there is a role for a probiotic and, if so, which strain and duration may be appropriate.
This is particularly important for children who are seriously ill or have conditions that affect their immune system, as probiotics may not be appropriate for everyone.
Take Home Message
The growing interest in the gut microbiome is a positive development. We are learning more about how closely the gut, nutrition and overall health are connected. But this does not mean that every child needs a probiotic supplement.
For a healthy child, a varied and balanced diet is usually a better foundation for gut health than routinely reaching for a probiotic product.
