Vitamin E is a fat-soluble nutrient that plays a crucial role in maintaining good health. It is a group of eight antioxidants that includes four tocopherols and four tocotrienols. Vitamin E was first discovered in 1922 by Herbert McLean Evans and Katharine Scott Bishop, who found that the nutrient was essential for proper reproduction in rats. Since then, researchers have continued to explore the many functions of vitamin E in the human body.

Functions of Vitamin E in the Body
Vitamin E has many important functions in the body. One of its primary roles is to act as an antioxidant, which means it helps protect cells from damage caused by free radicals. Free radicals are unstable molecules that can damage cells and contribute to the development of chronic diseases, such as cancer and heart disease.
Vitamin E also plays a role in maintaining a healthy immune system, as well as in the formation of red blood cells. Additionally, it may help reduce inflammation in the body and protect against age-related cognitive decline.
Risks Due to Deficiency
A deficiency in vitamin E can lead to a range of health problems, including muscle weakness, vision problems, and an increased risk of infections. It may also contribute to the development of certain neurological disorders, such as Alzheimer's disease.
