Therefore , vitamin A supplementation alone may reduce the risk of anemia , by improving hemoglobin and ferritin levels in individuals with low serum retinol levels
ABSTRACT Anemia is a worldwide public health problem that can be related to many causes , including vitamin A deficiency .
The aim of this study was to assess and estimate the effect of vitamin A supplementation ( VAS ) on iron status biomarkers and anemia in humans .
Supplementation with vitamin A and iron for nutritional anaemia in pregnant women in West Java, Indonesia
Nutritional anaemia , thought to be caused by iron deficiency , affects 50 - 70 % of pregnant women in the developing world . The influence of vitamin A and iron supplementation was studied in anaemic pregnant women in West Java , in a r and omised , double-masked , placebo-controlled field trial . 251 women aged 17 - 35 years , parity 0 - 4 , gestation 16 - 24 weeks , and haemoglobin between 80 and 109 g/L were r and omly allocated to four groups : vitamin A ( 2.4 mg retinol ) and placebo iron tablets ; iron ( 60 mg elemental iron ) and placebo vitamin A ; vitamin A and iron ; or both placebos , all daily for 8 weeks . Maximum haemoglobin was achieved with both vitamin A and iron supplementation ( 12.78 g/L , 95 % Cl 10.86 to 14.70 ) , with one-third of the response attributable to vitamin A ( 3.68 g/L , 2.03 to 5.33 ) and two-thirds to iron ( 7.71 g/L , 5.97 to 9.45 ) . After supplementation , the proportion of women who became non-anaemic was 35 % in the vitamin-A-supplemented group , 68 % in the iron-supplemented group , 97 % in the group supplemented with both , and 16 % in the placebo group . Improvement in vitamin A status may contribute to the control of anaemic pregnant women
Therefore , vitamin A supplementation alone may reduce the risk of anemia , by improving hemoglobin and ferritin levels in individuals with low serum retinol levels
