Vitamin A can be referred as a group of compounds seen in both plant and animal foods. It comes in two forms: provitamin A carotenoids and preformed vitamin A.

Preformed vitamin A is the active form of the vitamin, which can be readily used by the body. It is soluble in fat and located in animal foods, such as eggs and liver, and contains retinoid compounds such as retinoid acid, retinol, and retinal.

The correlation between diseases and Vitamin deficiency was first established in ancient Egypt. The Egyptians applied extracts from liver to the eyes of persons affected by night blindness due to poor nutrition.

It was suggested in 1892 that dieting may impact on susceptibility to diseases. This was based on an observation that children suffering from whooping cough or measles also developed blindness caused by a deficiency in vitamin A.

Further studies revealed that supplements containing carrots could lower the figures and intensity of respiratory diseases.

More studies in recent times have revealed that deficiency of vitamin A causes increased incidence of respiratory diseases, tuberculosis, malaria, HIV, etc.

Studies also revealed that a high dosage of vitamin A supplements in kids infected with measles heightened the number of immune cells known as circulating T cells. It was also revealed that vitamin A supplements could lower respiratory infections in infants.
