provitamin A
Beta-carotene, for one
Provitamin A refers to compounds the body can convert into vitamin A, most notably beta-carotene found in orange and yellow vegetables.
Unlike preformed vitamin A from animal sources, provitamin A comes from plant foods: Carrots are rich in provitamin A.
The body converts only what it needs, making overdose from dietary sources unlikely.
