Vitamin A
Vitamin A is a vital nutrient that supports various essential functions in the body. It plays a key role in maintaining healthy vision, especially in low light, and is important for immune function, skin health, and cell growth. There are two main forms of vitamin A: preformed vitamin A found in animal products like liver and dairy, and provitamin A carotenoids, found in colorful fruits and vegetables like carrots and sweet potatoes. A balanced diet typically provides sufficient vitamin A, but deficiencies can lead to vision problems and a weakened immune system.
