Vitamin A is a fat-soluble vitamin. It is vital for healthy vision, skin, and immune function. Vitamin A comes in two primary forms in our diet. It is found in animal products such as dairy, fish, and meat, especially liver. Provitamin A form in beta carotenoids are found in plant-based foods like fruits, vegetables, and other green, leafy plants. Beta-carotene, the most notable carotenoid, can be converted by the body into vitamin A as needed. Vitamin A is critical for eye health, enabling proper retinal functioning. It also plays a role in the growth and maintenance of the skin and mucous membrane cells, thereby acting as a barrier to bacterial and viral infections. Additionally, it supports immune function by helping to produce and function the white blood cells that fight off infections. Deficiency in vitamin A can lead to vision problems, including night blindness, and increase the risk of infections and certain skin conditions.
