Caption: Vitamin A. Artwork based on a polarised light micrograph of crystals of vitamin A. This is a fat-soluble vitamin essential for normal growth, bone and teeth formation, night vision, and protecting against infection. Vitamin A is found in animal foods such as liver, fish oils, egg yolk and dairy products. It is absorbed by the body in the form of retinol. Carotene, a pigment from sources such as vegetables and fruits, is converted into vitamin A in the liver. Vitamin A deficiency may lead to weight loss, growth problems, and dry eye (xerophthalmia) which can result in blindness. An excess of vitamin A can also be harmful.
