A provitamin is a substance that may be converted within the body to a vitamin. The term previtamin is occasionally used as a synonym, though it has its own distinct usage for Vitamin D. The term "provitamin" is used when it is desirable to label a substance with little or no vitamin activity, but which can be converted to an active form by normal metabolic processes.
