Extract: Studies were done on the effect of ascorbic acid and five amino acids (histidine, cystine, cysteine, valine and glutamic acid) on intestinal iron absorption in a group of ninety Egyptian infants and young children, of which fifty seven were healthy controls and thirty three were suffering from Fe deficiency anemia. Supplements tested promoted Fe absorption in healthy controls in the following order: valine>histidine>ascorbic acid. Cysteine, glutamic acid and cystine were found to have no significant effect. Supplementation with valine, ascorbic acid and histidine also increased intestinal Fe absorption in anemic subjects, but to a lesser extent than in controls. Supplementation of histamatinic therapy with these compounds is recommended. Their use is also suggested to improve the availability of the Fe content of everyday diets.
