Eating carrots to improve night vision is a myth. Beta-carotene, the orange pigment in carrots, is a precursor to vitamin A and helps your eyes adjust to dim light. Vitamin A won’t give you superpowers or cure your contact lens addiction, but it will support eye health.
Vitamin A boosts white blood cell formation and activity, helps reshape bone, maintains healthy endothelium cells, and regulates cell development and division for reproduction.
Preformed vitamin A and provitamin A carotenoids like beta-carotene are the main dietary sources of vitamin A. Animal products, fortified meals, and supplements contain preformed vitamin A. Plants contain carotenoids. Lycopene, lutein, and zeaxanthin are non-vitamin A dietary carotenoids with health benefits.
