Vitamin A and Carotene
Info source
Vitamin A is a fat-soluble nutrient that occurs in nature in two forms: preformed vitamin A and provitamin A, or carotene.
Carotene is derived from plants and is converted by the body to vitamin A.
Preformed vitamin A is concentrated in certain tissues of animal products in which the animal has metabolized the carotene contained in its food into vitamin A.
