Risks of Vitamin A
About 90% of vitamin A is stored in the liver. Vegetarians can meet their vitamin A requirements with sufficient intakes of deeply colored fruits and vegetables, with fortified foods, or both. Vitamin A deficiency is a major problem when diets consist of starchy staples, which are not good sources of retinol or β-carotene, and when the consumption of deeply colored fruits and vegetables, animal-source foods, or fortified foods is low. Vitamin A plays a role in mobilizing iron from liver stores, so vitamin A deficiency may also compromise iron status. Excessive intakes of pre-formed vitamin A can result in high levels of the vitamin in the liver – a condition known as hypervitaminosis A. No such risk has been observed with high β-carotene intakes.
