Description
Vitamin A, a fat-soluble vitamin crucial for many bodily functions, was first discovered in 1913 by American biochemists. Its discovery established that it was a nutrient essential for growth, eyesight, reproduction, and the maintenance of cells. The term "vitamin A" refers to a group of compounds, including retinol, retinal, and four carotenoids, among which beta-carotene is the most well-known. Humans mainly get their Vitamin A from foods, either in the form of retinol from animal sources like dairy products, fish, and liver, or as provitamin A carotenoids from plant sources such as dark-colored fruits, leafy vegetables, and vegetable oils.
