Premature formulas contain which additional elements when compared to term infant formulas?

• A. Calcium (Ca) and Phosphorus (P)
• B. Potassium and Phosphorus
• C. Sodium and Long-Chain Triglycerides
• D. Iron and Zinc

Answer: (A)

Premature formulas are fortified to meet the higher mineral needs of babies born early, who miss most of the mineral accretion that occurs in the last months of gestation. The most impactful additional minerals in these formulas are calcium and phosphorus, provided in higher amounts with a suitable balance because they work together for bone mineralization and growth. Premature infants rely on these nutrients to support rapid bone development outside the womb, so increasing Ca and P helps promote stronger bones as they catch up. Other elements like sodium or long-chain triglycerides are not uniquely added to preterm formulas in the same way, and while iron and zinc are important, their fortification isn’t the distinguishing feature that sets preterm formulas apart from term formulas.
