Introduction to Vitamin E

Vitamin E is a fat-soluble vitamin that plays a crucial role in maintaining the overall health of the body. It is a powerful antioxidant that helps protect the body from damage caused by free radicals, which are unstable molecules that can harm cells and contribute to the development of chronic diseases. Vitamin E is also essential for the proper functioning of the immune system, and it has been linked to a range of health benefits, including improved skin health, reduced risk of heart disease, and improved cognitive function.

Types of Vitamin E

There are eight different forms of vitamin E, but the most biologically active form is alpha-tocopherol. Other forms of vitamin E include beta-tocopherol, gamma-tocopherol, and delta-tocopherol, as well as four tocotrienols. Each form of vitamin E has a slightly different chemical structure, which affects its absorption and biological activity in the body.
