Vitamin A is a group of unsaturated nutritional organic compounds that includes retinol, retinal, retinoic acid, and several provitamins A carotenoids (most notably beta-carotene)
Vitamin A (retinol, retinoic acid) is a nutrient important to vision, growth, cell division, reproduction, and immunity.

Vitamin A is found in many foods, such as spinach, dairy products, and liver. Other sources are foods rich in beta-carotene, such as green leafy vegetables, carrots, and cantaloupe.
