Within the last few years, knowledge about vitamins has dramatically increased resulting in improved human requirements of many vitamins. This book presents a supplementation of vitamin A dose given over a period of time to children to figure out its effects, as well the correlation of infection and hemoglobin trends in children over different frequency of intervals has been recorded to figure out the results. This book highlights the current understanding of the possible association of infection and hemoglobin in children. The supplementation has been given to understand the potential of visible sign of micronutrient deficiency diseases, and their disappearance in children over the period of time. The book thus contains high quality references incorporating new updated discoveries. Unfortunately the hypothetical statement lacks sufficient scientific evidence support and the case study may suggest that vitamin A supplementation given over a period of time completely vanishes the relevant micronutrient deficiency diseases.
