Vitamin E: An Overview

Vitamin E is a group of fat-soluble compounds with antioxidant properties. It exists in eight different forms, with alpha-tocopherol being the most active in humans. It is essential for the proper functioning of many organs in the body, and it helps to protect cells from damage caused by free radicals.

Sources of Vitamin E

Vitamin E is found in various foods, including:

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

Functions of Vitamin E

Vitamin E has several important functions in the body, including:

• Antioxidant activity: It helps to protect cells from damage by neutralizing free radicals.
• Immune function: It supports the immune system and helps the body to fight off infections.
• Cell communication: It helps to regulate gene expression and cell signaling.
• Skin health: It is important for healthy skin and eyes.

Deficiency and Excess of Vitamin E

A deficiency of vitamin E is rare, but it can lead to nerve and muscle damage, vision problems, and an impaired immune response. On the other hand, excessive intake of vitamin E through supplements can cause bleeding problems, particularly in individuals taking blood thinners.

Recommended Intake

The Recommended Dietary Allowance (RDA) for vitamin E varies by age and sex. For children and adults, the RDA ranges from 4 to 15 milligrams per day.
