[Iron absorption after oral application of a combination of Fe2+-succinate and multivitamins (author's transl)].Arzneimittelforschung. 1977; 27(8):1606-8.A
The rate of iron absorption of Fe2+-succinate orally applied with multivitamins, was measured by means of whole-body counter in 45 subjects. The dosage was 330 mg ferrous succinate (115 mg Fe2+). Absorption was generally 4.5% (5.2 mg) in normal subjects, 8.6% (9.9 mg) in subjects with latent iron deficiency, and 29.6% (34 mg) in subjects with manifest iron deficiency. In women taking oral contraceptives and not suffering from iron deficiency, no significant increase in the iron absorption rate was measured.
