Child’s Gut Support — Functional Protein IgG + Lactoferrin
A targeted blend with IgG, Lactoferrin, and amino acids, formulated to support gut balance, nutrient absorption, immune defences, and healthy growth — helping children thrive every day.
Support Gut Balance
Helps maintain a healthy gut lining during critical growth years.
Support Nutrient Absorption
Helps improve uptake of iron, amino acids, and key nutrients for growth.
Support Immune Defences
Helps strengthen everyday resistance to seasonal bugs and common illnesses.
Support Healthy Growth
Helps fuel energy, development, and resilience during ages 1–12.
-
Picky eating and slow growth
Meals are a struggle — small appetite, pushing food away, and not keeping up on the growth chart.
-
Frequent tummy troubles
Bloating, loose stools, or digestive discomfort after meals that make it harder to absorb nutrients.
-
Catching every bug at school
Colds, fevers, or skin flare-ups that show up with seasonal changes or after school exposure.
-
Low energy compared to others
Getting tired faster than friends, missing out on play, or struggling to keep up with daily activities.
Functional Proteins
Support the gut barrier and mucosal surfaces, reducing digestive stress and improving balance during critical growth years.
Lactoferrin + Transferrin
Iron-binding proteins that regulate and carry iron — essential for nutrient absorption, energy, and immune balance.
Amino Acids
18 amino acids, including 9 essential, provide building blocks for healthy growth, development, and resilience.
Together By combining functional proteins with Lactoferrin, IG 5000 supports your child on two levels: creating a balanced gut environment for nutrient absorption, and directly fuelling growth, energy, and resilience.
- Picky eating, poor appetite, and slow growth.
- Bloating, diarrhoea, or poor nutrient absorption.
- Frequent colds, fevers, or skin flare-ups during seasonal change.
- Weak constitution, tiredness, or cross-infections at preschool/school.
- Whole Milk Powder (milk, soy)
- Enriched IgG Whey Fraction (milk)
- Bovine Immunoglobulin

When to Consider IG 5000 lactoferrin
1
Everyday pressures on growing kids
Children’s gut and immune systems are still developing. Picky eating, frequent tummy troubles, or catching every bug at school are all signs the gut–child axis needs extra support.
2
Everyday signals parents notice
- Small appetite and slower growth
- Digestive discomfort or nutrient absorption issues
- Frequent colds, fevers, or skin flare-ups
- Low energy compared to peers
These may all be signals that a child’s gut barrier and nutrient absorption need support.
3
Targeted Support
A blend of functional proteins and lactoferrin to fuel healthy growth.
We combine functional proteins (IgG) with lactoferrin, an iron-binding protein. Together they support gut balance, improve nutrient absorption, and strengthen everyday defences — helping children eat better, grow stronger, and stay resilient through the early years.
