Vitamin A is essential for the production of rhodopsin, a pigment in the retina that helps us see in low-light conditions. It also plays a vital role in the maintenance of epithelial tissues, which line our organs and skin. This nutrient can be found in two primary forms: preformed vitamin A (retinol) from animal sources such as liver and dairy products, and provitamin A (beta-carotene) from plant sources like carrots, sweet potatoes, and leafy greens.
