Brief Summary:

Anemia is one of the major health problems of the developing countries of the world [1]. According to the WHO reference criteria, an adult is labeled as anemic, if the blood hemoglobin concentration falls below 13.0 g/dL in men or less than 12.0 g/dL in the non-pregnant women [2]. Hemoglobin concentrations below the lower limit of normal are a common laboratory finding in apparently healthy people in general population all over the world [3-5]. Many of these mildly anemic individuals are not investigated sufficiently to establish the probable cause of their anemia and thus may end up with morbidity and health problems, especially the young women in developing countries [4].

Only few studies on the use of vitamin E in the correction of anemia have been published and hardly any on correction of mild anemia in healthy adults. The objective of this intervention study was to investigate the association of vitamin E supplementation with post-supplemental blood hemoglobin levels in mildly anemic healthy Pakistani adults.

Other Name: Evion

Placebo Comparator: placebo (edible oil) Drug: placebo (edible oil)

Primary Outcome Measures :
  1. Change in hemoglobin levels [ Time Frame: Change in hemoglobin levels in mildly anemic adults at baseline and after 3 months of intervention (vitamin E or placebo) in all the participants in intervention arm and placebo arm (end-line). ]
    Hemoglobin levels in blood were determined in mildly anemic adults before intervention (baseline) and after 3 months of supplementation with vitamin E 400 mg per day (end-line).
