Vitamin E

Vitamin E is a group of fat-soluble compounds that act as antioxidants in the body. The most biologically active form of vitamin E is alpha-tocopherol.

Sources of Vitamin E

Vitamin E is found in various foods, including:

• Vegetable oils (such as wheat germ, sunflower, and safflower oils)
• Nuts and seeds (such as almonds, sunflower seeds, and hazelnuts)
• Green leafy vegetables (such as spinach and broccoli)
• Fortified cereals and other fortified foods

Functions of Vitamin E

Vitamin E functions primarily as an antioxidant, protecting cells from the damage caused by free radicals. It also plays a role in immune function, DNA repair, and other metabolic processes.

Deficiency and Toxicity

A deficiency of vitamin E is rare but can lead to nerve and muscle damage. On the other hand, excessive intake of vitamin E supplements can lead to toxicity, characterized by symptoms such as nausea, fatigue, and impaired blood clotting.
