A key nutrient for the development of healthy bones, skin and eyes, vitamin A is a powerful antioxidant that helps fight free radical damage to help keep the immune system strong. Vitamin A is found in many animal sources (retinols) such as animal products, fatty fish, eggs and dairy, and in plant sources (beta-carotene) such as sweet potatoes and carrots. While deficiency is often rare, some watch-outs include night blindness and dry skin. Talk to you doctor before taking a vitamin A supplement to ensure it’s right for you.
