When it comes to choosing a probiotic for your baby, the options can feel overwhelming. Not all probiotics are the same, and different strains have been studied for different concerns—from colic and digestion to immune support.

Rather than focusing on marketing claims, it can be helpful to look at products that are commonly used in clinical practice and have some evidence behind them. Below are a few options to consider, depending on your baby’s needs.

Infant Probiotic Options

When I’m choosing probiotics for babies, I’m looking for products that are evidence-informed and practical for parents to actually use. Here are the ones I reach for most often in practice:

Best Probiotic Drops for Colic and Digestion

BioGaia Protectis Baby Drops

BioGaia Protectis Baby Drops probiotic for infants used for colic digestion and gut health

These drops contain Lactobacillus reuteri DSM 17938, one of the most well-studied probiotic strains for infants.

This strain has been researched for colic, constipation, and regurgitation—common concerns in early infancy. The liquid format makes it easy to use: it can be given directly, mixed into formula, or applied before feeding.

 

Where to find it:

Best Infant Probiotic for Diarrhea and Immune Support

Metagenics UltraFlora Baby

Metagenics UltraFlora Baby probiotic drops for infants with LGG and BB-12 strains for digestive and immune support

This formula combines Lactobacillus rhamnosus GG (LGG) and Bifidobacterium lactis (BB-12), two of the most widely studied probiotic strains in infants.

These strains have been researched for diarrhea (including antibiotic-associated diarrhea), colic, and immune support. The liquid format makes it easy to administer consistently.

 

Where to find it:

Best Multi-Strain Probiotic for Infants

Genestra HMF Baby Line

Genestra HMF Baby probiotic line for infants including drops and powders for digestive and immune health

This line includes several options (HMF Baby B, HMF Baby F, HMF Baby Immune, and drops), allowing for more tailored support depending on your baby’s needs.

These products combine multiple probiotic strains and come in both powder and liquid formats. Powders can be mixed into breastmilk, formula, or soft foods.

Dr. Domenique adds: Multi-strain probiotics can be helpful when you’re looking for broader digestive and immune support, especially when feeding method or health history varies.

Probiotics for your infant

The “best” probiotic for your baby will always depend on the specific concern you’re trying to support, along with your baby’s age, feeding method, and overall health.

If you’re unsure where to start, working with a healthcare provider can help you choose a product and strain that makes sense for your child. And remember—probiotics can be helpful in certain situations, but they’re just one piece of the bigger picture when it comes to infant gut health.
