Vitamin A is a fat-soluble vitamin that is essential for the normal-life activities of the human body. Its physiological functions include forming photosensitive substances in visual cells, affecting the stability and integrity of epithelial tissues, maintaining and promoting immune functions.

Prevention and treatment of vitamin A deficiency is necessary to prevent recurrent respiratory infections and asthma attacks and reduce the occurrence of bronchopulmonary dysplasia.
