Vitamin A is a group of unsaturated nutritional organic compounds that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids (most notably beta-carotene). Vitamin A has multiple functions: it is important for growth and development, for the maintenance of the immune system and good vision.
Vitamin A was first discovered in 1913 and today it is known to be important for several health issues. Vitamin A not only contributes to proper cell growth and repair, particularly of skin cells, but is also essential for strengthening night vision, assisting bone growth, and regulating the immune system. A deficiency of Vitamin A can lead not only to dry skin but also to dry hair, broken fingernails, and dry eyes.
