Adverse effect after cessation of rats' unjustified iron or iron and zinc supplementation on hematological parameters but not ferritin concentration

After cessation of unjustified both iron and iron/zinc supplementation resulted in an adverse effect on hematological but not other iron status parameters. In the situation of iron deficiency in the diet, iron supplementation alone had a prolonged beneficial effect and was more effective than simultaneous iron/zinc supplementation in the improvement of the iron status.
