Getting Started with Beginbaby Prebiotic + Probiotics

Welcome!

This guide introduces you to Begin Health’sBeginbaby Prebiotic + Probiotics.

We developed this baby formula booster to support your little one’s health, starting with the gut. 

Early gut disruptions such as those from C-section delivery, formula feeding, or early antibiotic exposure can alter the trajectory of your baby's health. 

Beginbaby Prebiotic + Probiotics provide a daily gut boost to formula-fed and combo-fed babies, helping create a strong foundation for a healthy gut and strong immune system.

What Beginbaby Prebiotic + Probiotics Does

Beginbaby is asynbiotic—combining bothprebiotics and probiotics—designed to seed and nourish a baby’s developing gut microbiome.

It features:

• 2’-FL Human Milk Oligosaccharide (HMO) – a prebiotic that mimics the benefits of breast milk.

• Bifidobacterium longum subsp. infantis – a powerful, baby-specific probiotic strain supporting gut development.

• Bifidobacterium animalis subsp. lactis (BB-12) – a well-researched probiotic shown to promote immune and digestive health.

In early infancy, the gut microbiome develops rapidly, impacting digestion, nutrient absorption, immunity, and even brain health throughout life.

Beginbaby helps mimic the natural gut-building process of breastfeeding, especially beneficial for babies who may not receive the full benefits of breast milk.

Why Your Baby’s Gut Needs Support

Birth method, antibiotic exposure, and feeding type all influence the infant gut microbiome:

• C-section births bypass exposure to beneficial maternal bacteria.

• Formula feeding may lack important prebiotics like HMOs.

• Antibiotics, even a single course, can disrupt early microbial balance.

These disruptions may contribute to issues like constipation, colic, eczema, and weaker immune response.

Beginbaby helps naturally build and replenish what nature intended by delivering beneficial bacteria along with the fuel they need to thrive.

Summary

Beginbaby Prebiotic + Probiotic supports the baby gut with a science-backed prebiotic + probiotic blend designed for infants. 

Whether breastfed, formula-fed, or combo-fed, Beginbaby helps build a resilient gut foundation.

What Are HMOs and Why Do They Matter?

Human Milk Oligosaccharides (HMOs) are the third most abundant component of human breast milk.

• HMOs arenot digestible by babies; they exist to feed beneficial bacteria.

• 2’-FL HMO supports the growth ofB. infantis, which predominates in the guts of breastfed babies.

• Research shows HMOs help shape immune development, block pathogens, and support gut lining integrity .

Beginbaby uses 2’-FL HMO, the most common HMO found in breast milk, and clinically backed for infant gut health.

What Do Bifidobacteria Do?

Probiotic strains likeB. infantis andB. lactis are naturally found in healthy infant guts.

• B. infantis is a keystone strain in breastfed babies, breaking down HMOs and lowering gut pH to inhibit harmful bacteria .

• B. lactis (BB-12) supports immune system training, gut barrier function, and stool consistency .

Studies show that babies with more B. infantis tend to have fewer gastrointestinal issues and healthier immune markers.

Tips on Getting Started with Beginbaby Prebiotic + Probiotic
