  Vitamin A is a lipid-soluble micronutrient that plays a vital role in cellular development, metabolism, immune function, vision, and reproductive processes. Insufficient intake or absorption of vitamin A can lead to a deficiency, impairing important physiological functions. Vitamin A deficiency (VAD) is a widespread health concern affecting young children and is associated with significant morbidity and mortality. According to the Institute of Medicine, the recommended dietary allowance (RDA) of vitamin A for healthy adults is 700 micrograms/day for women and 900 micrograms/day for men. Children, pregnant women, and lactating women have different RDAs, which are 300 to 900, 770, and 1300 micrograms/day, respectively. Ocular symptoms related to vitamin A deficiency have been observed to occur when blood concentrations are lower than 10 micrograms/dL. Inadequate nutrition compounded by chronic inflammation resulting from regular gastrointestinal (GI) infections is the primary cau...
