Vitamin A is a fat-soluble vitamin that is necessary for the proper function of the immune system, vision, and cell growth and differentiation. It acts as an antioxidant in cells and helps repair damage. It also helps ward off age-related macular degeneration (AMD), a leading cause of vision loss. Vitamin A is found in foods like liver, meat, fish, and dairy products. Another compound called beta-carotene is found in orange fruits and vegetables including cantaloupe, carrots, mangoes, sweet potatoes, and apricots. It is also found in spinach, red peppers, and broccoli. The body converts beta-carotene into vitamin A.
