Guide To Vitamin A Deficiency Symptoms

Vitamin A deficiency is a condition in which an individual does not have a sufficient amount of vitamin A in their body. Vitamin A helps develop and maintain mucous membranes, healthy teeth, soft tissue, skeletal tissue, and the retina. There are three different forms of vitamin A, including carotenoids, retinol, and beta carotenes. Vitamin A deficiency can occur when an individual's body is unable to absorb fats from consumed food, or when their metabolism has become altered. A lack of vitamin A ingestion can also result in this type of deficiency.
