Vitamin A<\/h1>\n<\/header>\n
\"\"<\/figure>\n

It\u2019s only a semi-myth that eating carrots will help you see in the dark. A carrot\u2019s main nutrient, beta-carotene (responsible for this root vegetable\u2019s characteristic orange color), is a precursor to vitamin A and helps your eyes to adjust in dim conditions. Vitamin A can\u2019t give you superpowers of night vision or cure your dependence on contact lenses, but eating an adequate amount will support eye health.<\/p>\n

Vitamin A also stimulates the production and activity of white blood cells, takes part in remodeling bone, helps maintain healthy endothelial cells (those lining the body\u2019s interior surfaces), and regulates cell growth and division such as needed for reproduction.<\/p>\n

The two main forms of vitamin A in the human diet are preformed vitamin A (retinol, retinyl esters), and provitamin A carotenoids such as alpha-carotene and beta-carotene that are converted to retinol. Preformed vitamin A comes from animal products, fortified foods, and vitamin supplements. Carotenoids are found naturally in plant foods. There are other types of carotenoids found in food that are not converted to vitamin A but have health-promoting properties; these include lycopene, lutein, and zeaxanthin.<\/p>\n

Recommended Amounts<\/strong><\/h3>\n

\u00a0<\/em>Vitamin A is currently listed on the Nutrition Facts label measured in international units (IU). However, the Institute of Medicine lists the Recommended Dietary Allowances (RDA) of vitamin A in micrograms (mcg) of retinol activity equivalents (RAE) to account for different absorption rates of preformed vitamin A and provitamin A carotenoids. Under the Food and Drug Administration\u2019s (FDA) new food and dietary supplement labeling regulations, as of July 2018 large companies will no longer list vitamin A as IU but as \u201cmcg RAE.\u201d [1]<\/p>\n
