Updated: July 30, 2025

As parents, we always want what’s best for our children’s health. Finding the best probiotics for kids is a great way to support their well-being. A high-quality children’s probiotic can improve digestion, help with constipation, and boost their immune system. With many options available for a kids probiotic, it can be challenging to find the perfect supplement for your child or toddler. In this 2025 guide, we’ll explore the top probiotics for kids, discuss safety, and help you make an informed decision.

Key Takeaways: Best Children’s Probiotic

  • Quality Matters: Investing in a high-quality probiotic for kids is crucial for a child’s developing gut microbiome. Avoid budget-friendly options that lack clinically-backed strains.
  • Top Overall Probiotic: Seed PDS-08 is our top recommendation. It’s the best pediatric probiotic for its comprehensive formula that supports digestion, immune health, and helps with eczema and asthma.
  • Best Budget-Friendly Option: For a more affordable yet effective choice, Ora Organics Trust Your Gut Pixies is a great alternative that kids love.
  • Key Benefits: The right probiotics for children can help with regular bowel movements, reduce antibiotic-associated diarrhea, support immune function, and improve skin health, as confirmed by scientific reviews.
  • Choosing a Probiotic: Look for products with specific, clinically-studied strains like Lactobacillus rhamnosus GG and Bifidobacterium infantis, and always consult a pediatrician to find the best children’s probiotic for your family.

What Are Probiotics for Kids?

A visual explanation of how the best probiotics for children work to support gut health.

Probiotics for kids are live, beneficial bacteria and yeasts that are essential for their overall health, particularly their digestive system. Often called “good” or “friendly” bacteria, these microorganisms help maintain a healthy balance within a child’s gut microbiota—a complex community of trillions of microorganisms vital for digestion, immune function, and well-being. Knowing the best time to take probiotics can further enhance their effectiveness.

They work by colonizing the gut, promoting the growth of beneficial bacteria while inhibiting harmful ones through mechanisms like competitive exclusion, as outlined in scientific literature. Found in probiotic foods like yogurt and sauerkraut, and available as dietary supplements, the best probiotics for children have been studied for numerous health benefits, including:

  • Improved digestive health and regularity.
  • Enhanced immune function through immunomodulation.
  • Relief from gastrointestinal issues like diarrhea and constipation.
  • Support for a child’s developing immune system.

What Are The Best Probiotics To Stop Diarrhea In Children?

A variety of probiotic forms that can help with diarrhea in children and toddlers.

When looking for the best probiotic for toddler diarrhea, specific strains have been shown to be particularly effective. The most researched and recommended strains are:

Types of Probiotic Strains For Kids

Understanding the specific strains in a children’s probiotic supplement can help you choose the best one for your child’s needs. For a deeper dive, explore our guide to the best probiotic strains. Here are some of the most beneficial and well-researched strains for kids:

Lactobacillus Rhamnosus GG (LGG)

The gold standard for kids’ probiotics. Excellent for reducing diarrhea, preventing respiratory infections, and treating eczema, with its efficacy supported by meta-analyses.

Bifidobacterium Infantis

A key bacteria in the infant gut, crucial for digesting breast milk and building a strong immune system. It helps reduce inflammation and symptoms of IBS.

Saccharomyces Boulardii

A beneficial yeast that is a powerhouse against diarrhea. It survives stomach acid well and helps restore gut balance, especially during and after antibiotic use.

Lactobacillus Acidophilus

A common and helpful strain that supports overall digestive health, helps absorb nutrients, and can reduce the risk of childhood illnesses.

How to Choose the Best Children’s Probiotic

Look for Clinically-Studied Strains

Not all probiotics are created equal. Choose products that contain well-researched strains for children, such as Lactobacillus rhamnosus GG, Bifidobacterium infantis, and Saccharomyces boulardii. Efficacy is strain-specific, not species-specific.

Consider the Form and Dosage

Pick a form your child will actually take, whether it’s a powder, chewable, or liquid. Ensure the dosage (measured in CFUs) is appropriate for your child’s age. Doses in clinical trials often range from 10^8 to 10^9 CFU/day.

Check for Quality and Purity

Opt for reputable brands that are transparent about their ingredients. The best probiotics for kids are free from artificial colors, sweeteners, preservatives, and common allergens.

Consult a Healthcare Professional

Before starting any new supplement, it’s always best to talk to your child’s pediatrician to ensure it’s the right choice for their specific health needs.

When to Start and Stop Giving Probiotics to Children

When to Start

Probiotics can be given at different ages, but it is crucial to consult a pediatrician before introducing them to infants, especially those with pre-existing health conditions. Some products are suitable for children as young as 3 months, but professional guidance is key. The FDA has issued warnings for premature infants.

When to Stop

There is no specific age to stop giving probiotics, as they can be beneficial throughout life. For acute issues like diarrhea after antibiotics, a one-month course may be sufficient. For ongoing support, continuous use is often safe, but it’s wise to check in with your healthcare provider periodically to assess your child’s needs.

What is the best children’s probiotic?

Based on our research, Seed PDS-08 is the best children’s probiotic overall due to its comprehensive synbiotic formula, clinical backing, and clean ingredients. For a budget-friendly option, Ora Organics Kids Pixies is an excellent choice.

What is the best probiotic for a 2 year old?

BioGaia Protectis drops are excellent for this age group, especially for colic and digestive comfort. Always consult your pediatrician before giving any supplement to a toddler.

Are there any side effects of probiotics for kids?

Probiotics are generally safe for healthy children. When first starting, some kids might experience mild gas or bloating as their gut adjusts. This is usually temporary. However, if your child has a compromised immune system or a serious illness, probiotics should be used with extreme caution, so consult a doctor before use.

Conclusion: Choosing The Best Kids Probiotic
