NAN Pro 3: Composition, Benefits, and Usage Guide

Choosing the right growing-up milk for toddlers is a decision many parents find genuinely stressful, especially when the shelves are full of options. NAN Pro 3 is a stage-3 toddler formula from Nestle, designed for children aged 1 year and above who are moving from breast milk or nfant formula  toward a more varied diet. This guide covers what goes into it, how it differs from earlier stages, how to use it safely, and when to call your pediatrician.

NAN Pro 3 is a growing-up milk formula made by Nestle. "Growing-up milk" is a broad category of fortified, milk-based drinks made for toddlers who have started eating solid foods but may still have nutritional gaps in their daily diet.

The formula is intended for toddlers from 12 months onwards. At this stage, a child's diet is expanding quickly, but it can still fall short on certain vitamins, minerals, and fatty acids that support rapid growth. NAN Pro 3 is designed to complement a balanced diet, not replace it, and it is not a substitute for breast milk in infants under 12 months.

NAN Pro 3 composition is built around the nutrient needs of toddlers in their second year of life and beyond. The key components, based on the brand's published label information, include:

Macronutrients

• A whey-predominant protein blend, which is generally easier for small stomachs to digest than casein-dominant proteins
• Carbohydrates from lactose and maltodextrin for sustained energy
• Vegetable oils that supply essential fatty acids

Micronutrients and Functional Additions

• DHA (docosahexaenoic acid), an omega-3 fatty acid linked to brain and eye development
• Iron, calcium, and vitamin D to support bone health and help prevent the deficiencies common in toddlers
• Vitamin C and zinc to support immune function
• Iodine, which is important for thyroid function and cognitive development

Probiotics

NAN Pro 3 contains L. reuteri, a probiotic strain that may help support gut comfort and digestive balance. Individual responses vary, so speak with your pediatrician if your child has a history of digestive issues.

The exact quantities per serving differ by pack size and batch. Always read the current label on the tin you purchase, as formulations can be updated periodically.

Understanding the NAN Pro 1 2 3 difference helps parents move through stages with more confidence.

  A few important points:

• NAN Pro 1 and 2 are infant formulas that fall under stricter regulatory oversight because they may serve as the sole source of nutrition.
• NAN Pro 3 is categorised as a growing-up milk and is always intended alongside solid foods.
• NAN Pro Excella is a separate premium line that comes in stage variants (Excella 1, 2, and 3) rather than being a single product. It uses partially hydrolysed protein across all stages, but this is not the same as a fully hypoallergenic formula for diagnosed cow's milk protein allergy.

NAN Pro 3 is a follow-on formula intended for toddlers, and it can be introduced at the age and stage recommended on the product packaging or by your child’s healthcare professional.

When to switch?

Most parents transition to NAN Pro 3 around their child's first birthday, which aligns with the recommended NAN Pro 3 age of 12 months and above. If your child is on NAN Pro 2, the switch can happen gradually over one to two weeks: start with one feed of NAN Pro 3 per day while continuing NAN Pro 2 for the rest, then progressively replace. Always confirm the timing with your pediatrician, especially if your child was born preterm or has an underlying medical condition.

Preparation steps

1. Wash hands thoroughly before preparing any feed.
2. Boil fresh water and allow it to cool to the temperature stated on the current product label.
3. Use only the scoop provided in the tin. Level each scoop with the flat edge of a clean knife; do not pack the powder down.
4. Add the recommended number of scoops to the measured water, not the other way around, to prevent overconcentration.
5. Close the bottle and shake until the powder is fully dissolved.
6. Check the temperature on the inside of your wrist before feeding.
7. Discard any leftover formula within one hour of preparation. Do not refrigerate and reuse prepared feeds.

Frequency and volume

NAN Pro 3 complements food rather than replacing it. As a general guide, two servings per day alongside three solid meals is common practice, but your pediatrician's recommendation takes priority over any general guidance.

NAN Pro 3 is not suitable for every child. Do not use it without medical advice if your child has:

• Cow's milk protein allergy (CMPA): NAN Pro 3 contains intact cow's milk protein. Children with confirmed CMPA need an extensively hydrolysed or amino acid-based formula prescribed by a doctor.
• Galactosemia: The formula contains lactose and is not safe for children with this rare metabolic disorder.
• Clinically diagnosed lactose intolerance: Children with diagnosed intolerance may need a lactose-free alternative rather than a standard growing-up milk.
• Any condition requiring a specialised formula: Always consult your doctor before switching formulas if your child has a chronic health condition.

If you are unsure whether NAN Pro 3 is appropriate for your child, speak to a pediatrician before introducing it.

Most toddlers tolerate NAN Pro 3 well. A small number may experience mild digestive changes when first introduced, such as softer or firmer stools, which often settle within a few days as the gut adjusts.

Signs that warrant a call to your doctor include:

• Persistent vomiting or diarrhoea after feeds
• Skin rashes, hives, or swelling around the mouth
• Unusual fussiness, gassiness, or signs of abdominal pain that do not resolve
• Blood in stools

These could indicate an intolerance or allergy that needs proper assessment.

Report adverse events to your healthcare provider or the relevant regulatory authority.

Prepared formula left at room temperature for more than one hour should always be discarded. Never add extra scoops to increase concentration, as this can cause dehydration and places strain on a toddler's kidneys.
