Vitamin A helps to keep eyesight and skin healthy and helps children to grow. Most people who have a normal diet do not need extra vitamin A. However, this vitamin is used to treat or prevent a lack of vitamin A and the problems that occur because of this lack (e.g., night blindness). Low vitamin A may occur with food absorption problems, diabetes, hyperthyroidism, liver disease, or cystic fibrosis with liver complications. Higher amounts of vitamin A may be required during pregnancy and breastfeeding.
