For parents of premature or low birth-weight babies, nutrition is everything. Aptamil FMS® Breast Milk Fortifier is a specialized supplement that enriches expressed breast milk with the extra protein, energy, and nutrients required for healthy weight gain and immune development in fragile newborns.

Why Use Aptamil FMS® for Preterm Baby Nutrition?

• ✔️ Increases protein, energy, calcium, phosphorus, and vitamins in breast milk
• ✔️ Developed for infants under 1,800 g or born before 37 weeks
• ✔️ Supports brain development, immune strength, and weight gain
• ✔️ Used in hospitals across Europe – trusted by pediatricians
• ✔️ Easy to mix: 1 scoop (4 g) per 100 mL of breast milk

Evidence-Based Benefits of Breast Milk Fortification

A 2020 Cochrane Review showed that fortifying breast milk leads to an additional ~2 g/kg/day in weight gain in premature infants. The ESPGHAN guidelines recommend fortified breast milk as the preferred nutrition for all babies under 1,800 g birth weight. Aptamil FMS® meets these standards.

Is Aptamil FMS® Safe for My Baby?

Yes. Although fortification increases osmolarity to ~436 mOsm/L, it remains well within the safe limit of 450 mOsm/L set by pediatric standards. It is safe for daily use under medical supervision.

Note: Aptamil FMS® may offer minimal choline, which is important for brain development. Discuss supplementation with your doctor if needed.

How to Mix Aptamil FMS® with Breast Milk

Add 1 level scoop (4 g) of Aptamil FMS® to every 100 mL of expressed breast milk. Mix until fully dissolved. This increases the calorie content to ~82 kcal per 100 mL.
