Vitamin E is a fat-soluble vitamin crucial for maintaining human health. Abundantly found in various foods like vegetable oils, fish, meat, eggs, and fruits, it plays an essential role in many bodily functions.
Functions of Vitamin E

Uses of Vitamin E
Beyond its role as a nutrient, vitamin E is used to treat vitamin E deficiency, which, although rare, can be caused by genetic disorders. Additionally, it is being explored for its potential in treating Alzheimer’s disease, menstrual cramps, and intracranial hemorrhage.
Structure and History
Vitamin E exists in eight different forms, categorized into tocopherols and tocotrienols. The first form is naturally occurring, while the second is synthetic. These forms differ based on the position of the methyl group.
Discovered in 1922 by Herbert Evans and Katherine Bishop, vitamin E was isolated in 1935. It took nearly fifty years for scientists to fully comprehend its importance.
