Vitamin E is a fat-soluble antioxidant that plays a crucial role in maintaining health and preventing disease. Often overshadowed by its more famous counterparts like Vitamin C and Vitamin D, Vitamin E is nonetheless vital for numerous physiological functions. This blog provides an in-depth look at Vitamin E, exploring its benefits, sources, potential deficiencies and excesses, and practical tips for ensuring adequate intake.
What is Vitamin E?
Vitamin E refers to a group of eight fat-soluble compounds known as tocopherols and tocotrienols. The most biologically active form of Vitamin E in humans is alpha-tocopherol, which is primarily responsible for its antioxidant effects. Vitamin E is found in various foods and is also available as a dietary supplement. As an antioxidant, Vitamin E helps protect cells from oxidative stress caused by free radicals—unstable molecules that can damage cells and contribute to aging and chronic diseases. By neutralizing these free radicals, Vitamin E plays a role in maintaining overall health.
