Vitamin A is used to prevent or treat low levels of the vitamin in people who do not get enough of it from their diets. Most people who eat a normal diet do not need extra vitamin A. However, some conditions (such as protein deficiency, diabetes, hyperthyroidism, liver/pancreas problems) can cause low levels of vitamin A. Vitamin A plays an important role in the body. It is needed for growth and bone development and to maintain the health of the skin and eyesight. Low levels of vitamin A may cause vision problems (such as night blindness) and permanent eye damage.
