Serum concentrations of vitamin E in healthy infants fed commercial milks

Serum vitamin E concentrations were determined in 60 term and 26 premature infants during the first 2 months of life. All infants received commercial milk formula containing vitamin E. In addition, premature infants older than 10 days were given vitamin E orally as a multivitamin preparation. Thus, daily intake of vitamin E was nearly 1.2 mg/kg body weight in term infants and 2–3 mg/kg body weight in premature infants.In term infants serum levels of vitamin E rose from 2.6 mg/l (cord blood) to 7.0 mg/l (3rd–13th day) and 9.1 mg/l (16th–25th day) and remained at 10 mg/l (in the second month of life). Hemoglobin concentration and red cell number decreased continuously due to physiological anemia of infancy. In premature infants mean values of vitamin E were the same as in term infants. Vitamin E deficiency with hemolytic anemia could be demonstrated in a 2 months old infant suffering from cystic fibrosis.Dedicated to Prof. Dr. H.-R. Wiedemann on the occasion of his 65th birthday
