A fat-soluble vitamin called vitamin A is essential for a variety of bodily processes, including healthy vision, a robust immune system, reproduction, and skin health. Preformed vitamin A and provitamin A are the two varieties of vitamin A that can be found in food. Retinol, also known as preformed vitamin A, is frequently present in meat, fish, eggs, and dairy products. The body, however, transforms the carotenoids found in plant foods like red, green, yellow, and orange fruits and vegetables into vitamin A. In developed nations, deficiency is uncommon, but many people in developing nations do not get enough vitamin A. Pregnant women, breastfeeding mothers, infants, and children are most at risk for deficiency. Your risk of deficiency may also be increased by cystic fibrosis and persistent diarrhea. Skin cells need vitamin A to grow and repair themselves. It also aids in reducing inflammation brought on by specific skin problems. Eczema and other skin conditions may be brought on by a lack of vitamin A in the body. Skin that is dry, itchy, and inflamed is a symptom of eczema. Alitretinoin, a prescription drug with vitamin A activity, has been shown in numerous clinical studies to be effective in treating eczema. People with chronic eczema who took 10–40 mg of alitretinoin daily saw up to a 53% reduction in their symptoms during a 12-week study. Remember that there are numerous reasons why people develop dry skin, but a chronic vitamin A deficiency may be one of them. The most well-known effects of vitamin A deficiency include eye problems. In extreme cases, not getting enough vitamin A can lead to complete blindness or dying corneas, which are characterized by marks called Bitot’s spots. Dry eyes, or the inability to produce tears, is one of the first signs of vitamin A deficiency.
