The most common preformed vitamin a is retinol, which is also called vitamin A1.
Provitamin A-carotenoid
Provitamin A carotenoid and is found in fruits and vegetables. The most abundant provitamin A is beta-carotene. Examples of other provitamins A-carotenoids are alpha-carotene and beta-cryptoxanthin. (source ◳)
The bioavailability of provitamin A-carotenoids in fruit and vegetables is lower than once believed. It is difficult to fulfill the daily requirements through plant foods alone. (source ◳)
