What are Probiotics? 

Probiotics are living microorganisms that, if consumed in appropriate quantities, can offer benefit to the person taking them. They are thought to be beneficial in a variety of ways, including: 

• Antimicrobial effect by modifying microflora

  • Modifying the microorganisms in your gastrointestinal tract so only good microorganisms stay instead of ones that can make you sick. 

• Secreting antibacterial substances 

• Competing with pathogens (bacteria, virus or microorganism that can cause disease) to prevent them from staying in your gastrointestinal tract. 

• Competing for nutrients that pathogens need to survive. 

• Modulating the immune system

• Regulating the allergic immune response 

Some common species of probiotics you might see: 

• Lactobacillus acidophilus

• Lacticaseibacillus casei

• Lacticaseibacillus paracasei

• Lactiplantibacillus plantarum

• Limosilactobacillus reuteri

• Lacticaseibacillus rhamnosus

• Bifidobacterium bifidum

• Bifidobacterium breve

• Bifidobacterium lactis

• Bifidobacterium longum

Does it Work? 

Studies in children have shown that probiotics can beneficial in cases of:

• Acute infectious diarrhea (diarrhea caused by a bacterial or viral infection). 

• Antibiotic associated diarrhea (diarrhea is a common side effect when taking antibiotics).

The effect probiotics can have in these cases (duration and severity of diarrhea) can be different for each child. Some children might have a modest response while others have a significant response. It’s also important that not all probiotics contain the same microorganism strains or the same amount. Response may vary depending on the probiotic product used. 

Are Probiotics Safe for Children? 

Generally, probiotics are considered safe in children if taken appropriately. Parents should be cautious and consult with their pediatrician if their child is immunocompromised, has had a transplant or less than 1 month of age.
