Los objetivos de este estudio fueron describir y comparar concentraciones de retinol, y tocoferol, grasa, energía y nitrógeno en fracciones de leche materna del principio y del final de muestras obtenidas en 24 horas de 24 madres de bebes muy pretermino (< 28 semanas de gestación) y la relación del contenido de vitamina A y E en la leche con la ingesta materna de vitaminas. Las concentraciones de retinol fueron significativamente mas altas en la leche del final que en la del principio (1.6 veces mas), como las concentraciones de -tocoferol (1.6 veces mas), -tocoferol (1.5 veces mas), grasa (1.7 mas), energía (1.3 mas), y nitrógeno (1.05 veces mas). El retinol, -tocoferol, -tocoferol se relacionaron positivamente (P < .05) con la energía y grasa de la leche, pero no con la ingesta materna. Estimados de ingesta o consumo de vitamina A y E de los bebes alimentados con leche del final junto a fortificantes de leche materna sobrepasaron los niveles mas altos de ingesta recomendados. El alto contenido de vitaminas solubles producida en la leche del final de madres de bebes de muy bajo peso al nacer necesita consideración en el diseño y las recomendaciones del uso de fortificantes de leche materna (HMF).
