vitamin A, oral

• Oral vitamin A is used to treat vitamin A deficiency. Carotene compounds (found, for example, in egg yolk, butter and cream) are gradually converted by the body to vitamin A (retinol). Vitamin A supports growth and bone development, vision, reproduction, and development and maintenance of skin tissue. It may also improve function of the immune system and prevent some cancers. A form of vitamin A called retinal is responsible for transmitting light sensation in the retina of the eye. Deficiency of vitamin A leads to night blindness.
