Probiotics and prebiotics are two terms that often appear in discussions about infant nutrition and formula labels. Both are included as ingredient features in some infant formulas — but what exactly are they, and what do they mean for your baby's formula choice? This guide explains what probiotics and prebiotics are, how they appear on formula labels, and what questions to bring to your pediatrician.
For a product-focused comparison of formulas that include prebiotics and probiotics, see our guide: Best Baby Formula with Prebiotics and Probiotics. This article explains what these ingredients are and how parents can read labels.
What Are Probiotics and Prebiotics?
Probiotics are live microorganisms included in some infant formulas as ingredient features. Different strains have different characteristics — specific strains matter, and the presence of a probiotic does not guarantee a specific health outcome. Individual responses vary. Probiotics can also be found naturally in fermented foods such as yogurt, sauerkraut, and kimchi.
Prebiotics are non-digestible fibers included in some infant formulas as formulation features. They are intended to support the gut microbiome environment. Common prebiotic types in formula include GOS (galacto-oligosaccharides) and FOS (fructo-oligosaccharides). Prebiotic sources in everyday foods include oats, bananas, peas, and other fiber-rich plants.
Together, prebiotics and probiotics are sometimes described as supporting the gut microbiome. Research in this area is ongoing — they are ingredient features, not clinical treatments. Always verify the current product label for specific strains and amounts.
Prebiotics and Probiotics in Baby Formula
Breast milk naturally contains oligosaccharides (HMOs) and certain bacteria that support the infant gut microbiome. No formula replicates breast milk. Some formulas include prebiotics or probiotics as formulation features — these are ingredient characteristics, not claims of providing the same benefits as breast milk. Individual responses to formula ingredients vary.
Babies also receive an initial exposure to bacteria during vaginal birth. Babies born via cesarean section or those born prematurely may have a different early microbiome exposure. Probiotic use in premature or medically fragile infants is a specialized medical topic and should only be discussed with a neonatal or pediatric specialist. This article does not provide guidance for premature infants or medical conditions.
As babies grow and begin eating solid foods, they will naturally receive prebiotics and probiotics from their diet. Many parents choose formulas that include these ingredients as part of their overall formula comparison — alongside age, feeding tolerance, and pediatric guidance.

Which Baby Formulas Include Prebiotics or Probiotics?
Not all infant formulas include prebiotics or probiotics. Here is an overview of EU organic options available through Organic Baby Formula Shop that include these ingredients as formulation features. Always verify the current product label, as formulations can vary by stage and market.
HiPP Combiotic Formula
The HiPP Combiotic Formula range includes GOS prebiotics and Lactobacillus fermentum CECT5716 as standard ingredient features across its stages. HiPP Combiotic uses algal oil as its DHA source. These are formulation characteristics — not medical treatments or disease-prevention claims. Always verify the current product label.
HiPP Hypoallergenic (HA) Formula
The HiPP HA Formula range uses partially hydrolyzed protein and includes prebiotics as a formulation feature. It is designed for precautionary use with a family history of allergy — not as a treatment for confirmed cow milk protein allergy. Always verify the current product label and consult your pediatrician.
Both formula lines are produced using EU organic certified ingredients designed to provide nutritionally complete infant feeding. Formula choice should be based on your baby's age, health, feeding pattern, and medical guidance.
How to Read a Formula Label for Prebiotics and Probiotics
When comparing formulas, look for:
- Probiotic strain name: Look for the full strain name (genus + species + strain code, e.g., Lactobacillus fermentum CECT5716) rather than a generic "probiotic blend" without further detail.
- CFU count: Colony-forming units indicate the amount of live bacteria. This varies by product and stage.
- Prebiotic type: GOS, FOS, or HMOs are the most common types in EU organic formula. Ingredient type and amount vary by brand and stage.
- DHA source: Algal oil (plant-derived) or fish oil. Always verify on the current product label.
Always verify the current product label. Formulations can change between stages and markets.

When to Ask Your Pediatrician
Formula choice is personal and should be based on your baby's age, health, feeding pattern, and medical guidance. Consult your pediatrician if:
- Your baby was premature or has a low birth weight — probiotic use in preterm or medically fragile infants requires individualized medical advice
- Your baby has recurrent infections, digestive symptoms, allergies, or poor growth
- You are considering switching formula for any health-related reason
- You have concerns about your baby's growth, development, or overall health
