For parents navigating food allergies, finding safe and effective supplements can be a challenge.

One common concern is whether kids with acasein allergy,an allergy to the protein found in milk, can safely take Growing Up Prebiotics

Let’s break down what casein allergy is, how it differs from lactose intolerance, and howGrowing Up Prebioticsis a safe option.

What Is a Casein Allergy?

Acasein allergy occurs when the immune system mistakenly identifiescasein, a protein in cow’s milk, as a harmful substance.

This triggers an allergic reaction, which can range from mild symptoms (hives, upset stomach) to severe reactions like anaphylaxis.

Unlike lactose intolerance, which results from the body's inability to digest lactose (a milk sugar), a casein allergy is an immune response that requires strict avoidance of all milk proteins

Is Growing Up Prebiotics Casein-Free?

Yes!Growing Up Prebiotics does not contain casein.

As for kids with Cow's Milk Protein Allergy, read more here from our nutrition scientist about what you need to know about lactose and cow's milk allergies.

The key prebiotic in Growing Up Prebiotics is Human Milk Oligosaccharides (HMOs),a powerful prebiotic fiber that supports gut health.

While HMOs are naturally found in human breast milk, the HMOs in Growing Up Prebiotics are  produced through fermentation, not extracted from actual human milk. 

This means they are structurally identical to those in breast milk and contain the exact same nutrition benefits without using actual milk. 

Can Kids with a Casein Allergy Safely Take Growing Up Prebiotics?

Yes,  Growing Up Prebiotics is safe for kids with a casein allergy

However, for toddlers or kids with severe food allergies, it’s always a good idea to consult with a pediatrician before introducing any new supplement.

Why HMOs Are Beneficial for Kids with Allergies

Toddlers or kids with food allergies often experiencegut imbalances due to immune system overactivation. Early-life nutrition during infancycan also high impact how allergies develop over time. HMOs, as a prebiotic, help: 

  1. Nourish beneficial gut bacteria, likeBifidobacterium infantis, which plays a role in immune regulation.

  2. Strengthen the gut barrier, reducing inflammation and improving overall digestive health.

  3. Support immune function, helping the body better tolerate food and environmental allergens.

Summary

Growing Up Prebiotics is safe for kids with a casein allergy, as it does not contain any ingredients derived from cow's milk. 

The HMOs in the formula are produced through fermentation, making them bioidentical to those in breast milk and provides the same nutrition benefits. 

Parents looking for a gut-friendly supplement for their little ones with allergies can feel confident in adding Growing Up Prebiotics to their routine.
