Vitamin A is an essential nutrient that supports vision, immune function, and skin health. It comes in two primary forms: preformed Vitamin A (retinoids) from animal products and provitamin A (carotenoids) from plant-based foods like carrots and sweet potatoes. Retinoids, such as retinol, are crucial for skin repair, while carotenoids like beta-carotene convert into active Vitamin A in the body.
This vitamin plays a key role in maintaining good eyesight, particularly night vision, by supporting the function of rhodopsin, a protein necessary for seeing in low light. It also strengthens the immune system by aiding in the production of white blood cells, which help the body fight infections, and promotes healthy skin by encouraging cell turnover and wound healing.
Vitamin A deficiency can lead to night blindness, weakened immunity, and skin issues, while severe deficiencies may cause xerophthalmia, a condition that can result in permanent blindness. It's important to consume Vitamin A from both animal and plant sources, but excessive intake, especially from supplements, can lead to toxicity.
