What is vitamin A?
Vitamin A is found in foods such as milk, cheese, eggs, butter, fortified margarine, meat, liver, oily saltwater fish, grains, oils, carrots, squash, dark green and yellow vegetables, and fruits such as cantaloupe or apricots. Vitamin A is important for the eyes and skin, the immune system, and for normal growth.
Vitamin A is a fat-soluble vitamin that is absorbed with fats in your diet and stored in your body's fatty tissue.
Vitamin A is used to treat vitamin A deficiency.
Vitamin A is possibly effective in preventing cataracts, or slowing the progression of retinitis pigmentosa (an eye disease that causes damage to the retina). Vitamin A is also possibly effective in preventing diarrhea in pregnant women who are malnourished.
