Vitamin E

What is Vitamin E?

Vitamin E is a powerful fat-soluble antioxidant that plays a crucial role in human health. It is a group of compounds that includes tocopherols and tocotrienols.

How does it work in the body?

In the body, vitamin E acts as an antioxidant by neutralising free radicals, which are unstable molecules that can cause damage to cells and tissues.

Scientific benefits

Several studies have demonstrated the potential health benefits of vitamin E.

A study published in Dermatologic Therapy demonstrated that topical application of vitamin E can enhance skin recovery after sun damage.

Dosage and recommendations

The recommended daily dose of vitamin E varies depending on age and sex. For adults, the recommended dose is approximately 15 mg (22.4 IU) per day. It is important to note that excessive vitamin E intake can have adverse effects, including an increased risk of bleeding, especially if taken in combination with anticoagulant medications. It is advised to consult a physician before starting vitamin E supplementation, particularly for those with underlying health conditions.

Best sources and forms

Vitamin E occurs naturally in many foods. Some of the best sources include:

• Nuts and seeds, especially almonds and sunflower seeds
• Green leafy vegetables, such as spinach and broccoli
• Vegetable oils, such as wheat germ oil, sunflower oil, and olive oil
• Whole grain products
• Avocado

There are different forms of vitamin E, including natural and synthetic. Natural vitamin E (d-alpha-tocopherol) is considered more biologically active than the synthetic form (dl-alpha-tocopherol), and it is recommended to choose natural sources when possible.

Side effects and warnings

Although vitamin E is safe for most people at recommended doses, high intakes can lead to side effects. Common side effects include:

• nausea
• diarrhoea
• fatigue
• increased risk of bleeding

Individuals taking anticoagulant medications or with certain health conditions should be especially cautious and consult a doctor before taking vitamin E supplements.
