Vitamin A Definition
What Is Vitamin A?

Any of several vitamins (as from egg yolk or fish-liver oils) required especially for good vision. Vitamin A also known as retinol, a fat-soluble vitamin which helps in the normal functioning of the mucus membranes of the eye and respiratory tract, and the formation of visual pigments in the eye. It is also essential for normal tissue growth and differentiation. Essential in the diet either as the preformed vitamin (retinol) found in animal foods or as a precursor, carotene, found in plant foods (usually both are present in the diet). It is mainly required for control of growth, cell turnover and fetal development, maintenance of fertility, and maintenance of the epithelial tissues lining the mouth and respiratory and urinary tracts; essential in vision.
