Vitamin A, a fat-soluble vitamin, plays essential roles in vision, growth, and
development; the development and maintenance of healthy skin, hair, and mucous
membranes; immune functions; and reproduction.
Vitamin A is also called retinol.
Measurement of the amount of vitamin A is
taken in retinol activity equivalents (RAE). Carotene, an orange pigment found
in food, is split by the body to become two active units of vitamin A. This is
also important when calculating the amount of vitamin A in the body.
The Recommended Daily Allowance (RDA) for vitamin A is 700 RAE per day for
women and 900 RAE per day for men. The RDA given is for adults and changes for
women who are pregnant or lactating.
A good source of vitamin A contains substantial amounts of vitamin A and/or
carotene in relation to its calorie content and contributes at least 10% of the RDA for vitamin A in a serving.
