Vitamin A (retinol, retinoic acid) is a fat-soluble vitamin important for vision, growth, cell division, reproduction and immunity. It also has antioxidant properties.

Vitamin A is present in many foods, such as spinach, dairy products and liver. Other sources are foods rich in beta-carotene, such as leafy vegetables, carrots and cantaloupe. Your body transforms beta-carotene into vitamin A.

The second type, provitamin A, is found in fruits,vegetables and other products of vegetable origin. The most common type of provitamin A present in foods and dietary supplements is beta-carotene.
