Vitamin E is a vital nutrient recognized for its powerful antioxidant properties and essential role in maintaining healthy skin, vision, and immune function. Scientifically, it refers to a group of fat-soluble compounds, with alpha-tocopherol being the most biologically active and commonly known form.

What Is Vitamin E?
Vitamin E is a group of eight fat-soluble compounds, including four tocopherols and four tocotrienols. These compounds act as antioxidants, protecting cells from oxidative stress caused by free radicals. Free radicals are unstable molecules that can damage cell structures, contributing to aging and various diseases.
Chemical Names and Forms of Vitamin E
Form | Scientific Name | Main Source | Bioavailability |
---|---|---|---|
Alpha-tocopherol | d-alpha-tocopherol | Vegetable oils, nuts | Most active in humans |
Beta-tocopherol | d-beta-tocopherol | Cereal grains | Moderate |
Gamma-tocopherol | d-gamma-tocopherol | Soybean and corn oils | High in typical diets |
Delta-tocopherol | d-delta-tocopherol | Vegetable oils | Lower |
Tocotrienols | Alpha, Beta, Gamma, Delta | Palm oil, rice bran | Emerging research |
