Radiolabelled tablets of slow-release iron and ferrous sulphate containing 50 mg of elemental iron were given to 28 patients, and iron absorption was studied using a whole body counter.
There was no significant difference between the absorption of ferrous sulphate and that of slow-release iron in normal subjects, anaemic patients, anaemic and non-anaemic post-gastrectomy patients, or those with coeliac disease. Ascorbic acid potentiated iron absorption, especially in anaemic post-gastrectomy patients.
The indications and hazards of slow release iron preparations are discussed.
