Top 5 Probiotics for Kids: Boosting Digestive Health & Immunity


Probiotics can help balance a child’s gut bacteria, promote digestive health, boost immunity, and alleviate specific symptoms such as colic in newborns, constipation, and acid reflux. In this article, we’ll suggest five top-rated probiotics for kids. However, before giving your child any probiotic supplement, it’s a good idea to consult with a pediatrician to ensure it’s safe and tailored to your child’s health needs.

Clinically proven probiotics for newborns

BioGaia Protectis probiotic drops are suitable for newborns and older, known for their safety and effectiveness. The main ingredient is L. reuteri. Clinical studies have shown that this strain can effectively relieve symptoms of colic, vomiting, occasional constipation, and diarrhea. It’s available in two formulations: a standalone probiotic (5ml) and a probiotic combined with Vitamin D3 (10ml).

L. reuteri is among the most extensively researched probiotic strains. According to information from BioGaia, as of December 2022, the efficacy and safety of various L. reuteri strains from BioGaia have been confirmed in about 258 clinical studies involving roughly 21,000 participants. 127 of these studies were on newborns to 18-year-olds, while 131 were on adults.

L. reuteri is one of the few bacteria that evolved alongside humans. A crucial member of the gut microbiota, it plays an essential role in helping infants digest breast milk and solid foods. This bacteria binds closely to the intestinal wall, improving immune response. However, due to modern lifestyles—including low-fiber diets, improved sanitation, antibiotic use, and C-section births—most people lack L. reuteri in their gut. Through probiotics, L. reuteri can be reintroduced into the body.

User feedback from over 10,000 users on iHerb indicates that these probiotic drops effectively alleviate symptoms like reflux and colic. Some parents noted that after trying various remedies without success, BioGaia Protectis drops showed significant relief, with their babies having regular bowel movements and a notable decrease in colic.

BioGaia Protectis drops are free from artificial colors, flavors, dairy, and soy. They contain non-GMO sunflower oil and natural palm kernel oil. Using them is easy: 5 drops regardless of the baby’s age (a 5ml package lasts about 50 days). The drops are tasteless and can be mixed with breast milk, formula, or any food below body temperature, making feeding convenient.

One thing to note is that, compared to other brands, BioGaia Protectis drops are a bit pricier. Once opened, they have a 3-month shelf life. However, considering their safety and efficacy, they’re an excellent choice for parents seeking a quality probiotic supplement.

Frequently Asked Questions about Kids’ Probiotics

What are sources of probiotics for children?

Probiotic supplements usually contain an indigestible component called ‘prebiotics’ that fosters the growth of gut bacteria. Infants can typically get prebiotics from their mother’s breast milk. Until about six months of age, breast milk remains the primary source of prebiotics.

Formula milk doesn’t offer the natural probiotics found in breast milk. That’s why some products attempt to add probiotics to the formula to mimic the health benefits of natural breast milk.

What are the benefits of kids’ probiotics?

Research has found that probiotics can help treat conditions in kids such as diarrhea and eczema, control allergies, prevent urinary tract infections, and alleviate symptoms of colic in newborns.

Other conditions that might benefit from probiotics include:

  • Atopic disorders
  • Necrotizing enterocolitis
  • Antibiotic-related diarrhea
  • Acute infectious diarrhea
  • Chronic inflammatory bowel diseases

Probiotics might also help treat or prevent the following conditions not specific to children:

  • Acne
  • Asthma
  • Atopic dermatitis
  • Constipation
  • Clostridium difficile infection
  • Diverticulitis
  • Traveler’s diarrhea
  • Urinary tract infections
  • Upper respiratory tract infections
  • Allergic rhinitis (hay fever)
  • Irritable bowel syndrome
  • Hepatic encephalopathy
  • Cavities
  • Periodontal disease

Are there side effects for kids taking probiotics?

They’re generally considered safe, but probiotics can potentially cause conditions like:

  • Systemic infections
  • Impaired metabolic activities
  • Over-stimulation of the immune system
  • Gene transfer

What are natural food sources of probiotics?

Several everyday foods contain probiotics that can increase the beneficial microbes in the body. Foods rich in probiotics include:

  • Yogurt
  • Cheese
  • Pickles
  • Miso
  • Kombucha tea
  • Buttermilk
  • Sourdough bread
  • Fermented foods

How to identify processed foods with probiotics?

Foods might not always label their probiotic content. If you’re buying yogurt with probiotics, make sure it’s pasteurized. Also, check the ingredient list to ensure it contains live cultures. Yogurt labels usually specify the particular strains of probiotics present, and there should be at least 100 million live cultures per gram.

Fermented foods also contain probiotics. The fermentation process preserves food and promotes the growth of probiotics. Foods that can be fermented include cabbage, cucumbers, and soybeans. Various methods, like adding yeast or bacteria, can facilitate the fermentation process.
