8 Signs and Symptoms of Vitamin A Deficiency

Vitamin A is a fat-soluble vitamin that is important for many bodily functions, including proper vision, a strong immune system, reproduction and good skin health.

There are two types of vitamin A found in foods: preformed vitamin A and provitamin A (1).

Preformed vitamin A is also known as retinol and commonly found in meat, fish, eggs and dairy products.

On the other hand, the body converts carotenoids in plant foods, such as red, green, yellow and orange fruits and vegetables, into vitamin A (2Trusted Source).

While deficiency is rare in developed countries, many people in developing countries do not get enough vitamin A.

Those at highest risk of deficiency are pregnant women, breastfeeding mothers, infants and children. Cystic fibrosis and chronic diarrhea may also increase your risk of deficiency.

Dry skin
