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 .
Effect of vitamin A supplementation on haemoglobin and vitamin A levels during pregnancy.
About 450 pregnant women from a low-income group were recruited to study the effect of vitamin A supplementation on plasma vitamin A levels  in the mother and cord and on the birth weights of the neonates . Results showed that supplementation with 1800 micrograms vitamin A/d for more than 12 weeks prevented the decline in plasma vitamin A that otherwise occurs during the last few weeks of pregnancy . This improvement in maternal values for vitamin A at a critical time of development favourably affected availability to the fetus , as reflected by the marked elevation in cord levels . Supplementation for a period of 12 weeks was found to be sufficient , since subsequent discontinuation did not alter the beneficial response . Apart from increasing maternal and cord vitamin A levels , vitamin A supplementation along with iron prevented , in this study , the significant decline in haemoglobin occurring at 26 - 28 weeks of gestation . The birth weights were not altered by vitamin A supplementation
Therefore , vitamin A supplementation alone may reduce the risk of anemia , by improving hemoglobin and ferritin levels in individuals with low serum retinol levels
