Vitamin A (Beta Carotene)

Along with vitamins D, E, and K, vitamin A is classified as a fat-soluble vitamin. One half of the body's available supply of Vitamin A is preformed, meaning that it is biologically ready for use in the body. Preformed Vitamin A occurs only in animal based foods (i.e. organ meats, eggs, and meat products). Biologically active forms of Vitamin A include retinol (alcohol and aldehyde), and retinal esters (retinal acetate and palmitate). The many fortified foods and vitamin supplements consumed by Americans today consist of the preformed Vitamin A, usually the retinal ester based form of the vitamin.


Carotenoids, precursors to vitamin A, are found in many of the most popularly consumed plant sources within the human diet. Carotenoids constitute approximately 1/2 of our daily dietary intake of Vitamin A. A key in determining the given availability of Vitamin A in a given fruit or vegetable is the color it provides. The more vivid and deeper colors of produce, (orange, yellow, and green), the higher the Vitamin A value that particular fruit or vegetable provides. Beta Carotene is the most active and predominant form in fruits and vegetables.
