E as in Vitamin E

What is Vitamin E?

Vitamin E is composed of a group of several related compounds, the tocopherols. They are distinguished from each other by a letter of the Greek alphabet (alpha, beta, etc.), and are found in the form of a yellow oily liquid. Its most active form is α-tocopherol.

Vitamin E is a powerful antioxidant. It is said to be fat-soluble, meaning it is soluble in fats.

Vitamin E is poorly synthesized by the body, which is why it is important to ensure sufficient intake through diet.

How Vitamin E Works

Since Vitamin E is fat-soluble, it is stored in the liver to compensate for potential deficiencies. It protects the cell membranes of the body by preventing the spread of free radicals.

Vitamin E is transported in the blood to target tissues via very low-density lipoproteins (VLDL) and acts on cell membranes. It is then stored in adipose tissues and muscles.

Benefits of Vitamin E

Vitamin E's main function is cell protection, but it also contributes to maintaining a healthy immune system and preventing chronic diseases (heart disease, cancer). Its antioxidant action helps stabilize unsaturated fatty acids, thereby protecting the cell membrane from oxidative stress.

Furthermore, sufficient vitamin E intake also helps prevent brain aging by preserving cognitive abilities.

Sources of Vitamin E

A varied and balanced diet provides sufficient vitamin intake. In food, it is most often found in its γ-tocopherol form.

It is primarily found in fatty foods such as fish, walnuts, almonds, hazelnuts, seeds, avocado, and vegetable oils, such as wheat germ oil, sunflower oil, or avocado oil.
