Vitamin A is an essential nutrient that is important for a variety of bodily functions, including vision, immune system health, and skin health. It is a fat-soluble vitamin, which means that it is stored in the body’s fat cells and can build up to toxic levels if consumed in excess.
There are two main forms of vitamin A: retinoids and carotenoids. Retinoids, such as retinol, are found in animal-derived foods like dairy products, egg yolks, and the liver. Carotenoids, such as beta-carotene, are found in plant-based foods like fruits and vegetables. The body can convert carotenoids into retinoids, which it can then use.
Some signs of vitamin A deficiency include night blindness, dry eyes, and dry skin. Long-term deficiency can also lead to more serious health problems, such as blindness and an increased risk of infection.
It is important to note that excessive intake of vitamin A can also lead to negative health effects, such as birth defects, liver damage, and osteoporosis. It is recommended to get vitamin A from food sources and consult with a doctor or dietitian before taking any supplement.
