Vitamin A Betacarotene

Vitamin A is a group of unsaturated nutritional organic compounds that includes retinol, retinal, retinoic acid, and several provitamin A carotenoids (most notably beta-carotene).

Vitamin A is an essential vitamin required for vision, gene transcription, boosting immune function, and great skin health. A deficiency of vitamin A can lead to blindness and increased viral infection, however, deficiency is only considered a problem in developing countries where it is a leading cause of blindness in children. Overconsumption of vitamin A can lead to jaundice, nausea, loss of appetite, irritability, vomiting, and even hair loss.

Vitamin A is a fat-soluble vitamin, and therefore, needs to be consumed with fat in order to have optimal absorption. High vitamin A foods include sweet potatoes, carrots, dark leafy greens, winter squashes, lettuce, dried apricots, cantaloupe, bell peppers, fish, liver, and tropical fruits. The current daily value for Vitamin A is 5000 international units (IU).
