Synthesized evidence indicates that addition of multiple micronutrients to Fe supplementation may only marginally improve Hb response compared with Fe supplementation alone .
However , addition of ' other micronutrients ' may have a negative effect .
Routine addition of unselected multiple micronutrients to Fe therefore appears unjustified for nutritional anaemia control programmes
OBJECTIVES To study the effect of combining multiple ( two or more ) micronutrients with Fe supplementation on Hb response , when compared with placebo and with Fe supplementation , in children .
Running performance in Gambian children: effects of water-soluble vitamins or iron.
Sixty-nine boys and girls between 10 and 14 years , with evidence of sub clinical vitamin deficiencies and poor iron status were enrolled into the study at the beginning of the rainy season . Children were allocated to three treatment groups to receive five times weekly either a placebo , 200 mg ferrous sulphate or 5 mg riboflavin and 150 mg ascorbic acid . Before receiving the supplement , and 9 weeks later , children performed an exercise regimen on a treadmill during which expired air was collected and heart rate measured . There was a general deterioration in the running performance of the children during the study period which was not affected by either the iron or the vitamin supplement
