Abstract
Differences between feeding practices in earlier investigations prompted the present study of iron and vitamin E supplementation in breast milk fed preterm infants. A new and highly sensitive technique for quantitation of alpha‐tocopherol in serum was used. Studies on 34 infants with a birth weight below 2000 g or gestational age ≤35 weeks showed that supplementation with 16.5 mg tocopheryl acetate/day from 10 days of age resulted in a significantly higher haemoglobin concentration and lower reticulocyte count at 8–10 weeks than supplementation with 1.5 mg/day (p++ (as ferrous succinate)/kg/day. It is concluded that extra supplementation with vitamin E is advisable also in breast milk fed preterm infants. A low dosage iron supplementation from 3 weeks of age is safe.
