This way, the deficiency of such vitamins occurs less since there is a storage plan available. This vitamin was discovered ages ago to be used in treatment of blindness and night blindness as well. Vitamin A is usually related with the eyes and their proper visual effect since it plays a huge part in the visual cycle but this vitamin has to do with the skin as well. Youâ€™ll see what happens if there isnâ€™t enough vitamin A and also when the vitamin is also taken in excessive amounts. An adult male or female require about 3000 international units of Vitamin A per day. However, the recommended daily intake is about 5000 international units. However, in stages of pregnancy or lactation and even infectious diseases, the requirement for vitamin A increases.
