. Serum concentrations of vitamin A were measured in term infants ( n =72) and their mothers at delivery and after 20 weeks of breast‐feeding ( n =48). During the 20 weeks the infants received either no supplemental vitamin A (but the mothers were given 3000 IU vitamin A daily) ( n =16) or a daily vitamin A supplementation of 600 ( n =17) or 1500 IU ( n =15). After 20 weeks of breast‐feeding the vitamin A levels in the unsupplemented infants were similar to those at birth. The infants supplemented either with 600 or 1500 IU had higher vitamin A serum levels than at birth ( p <0.01), however, there was no difference between the two supplemented groups. During lactation, the serum vitamin A concentrations of the mothers increased significantly in all groups with or without vitamin A supplementation.
