Vitamin A is a fat-soluble vitamin essential for various bodily functions. It plays a crucial role in maintaining healthy vision, supporting the immune system, and promoting proper growth and development. There are two main forms of vitamin A: retinol, found in animal products, and provitamin A carotenoids, found in plant-based foods like carrots and spinach. A deficiency in vitamin A can lead to serious health issues, including night blindness and a weakened immune response. To ensure adequate intake, it is important to consume a balanced diet that includes sources of vitamin A, such as dairy products, fish, and colorful fruits and vegetables.
