Vitamin E: Benefits, Deficiency, Side Effects and Source

Vitamin E, also known as tocopherol, is a potent fat-soluble antioxidant that plays a pivotal role in many physiological functions. It has been lauded for its numerous health benefits, ranging from boosting the immune system to aiding in the prevention of cardiovascular diseases. However, similar to other nutrients, maintaining a balance is key. While it’s vital to ensure sufficient Vitamin E intake to harness its benefits, one must also be aware of the symptoms and health implications of its deficiency. This article explores the roles, benefits, sources of Vitamin E, and the potential side effects of its deficiency.

Roles of Vitamin E

Vitamin E is a powerful antioxidant that helps protect cells from oxidative stress caused by free radicals. It has many functions in the body, including regulating enzyme activities and gene expression, maintaining cell membrane integrity, and supporting immune function. Additionally, vitamin E’s anti-inflammatory properties help reduce inflammation in the body, which can contribute to chronic diseases such as cancer and heart disease.

Benefits of Vitamin E

Research has shown that Vitamin E provides numerous health benefits, some of which include:

  • Boosting the immune system: Vitamin E helps maintain a healthy immune response by promoting the production of natural killer cells and T-cells.
  • Protecting against cardiovascular diseases: Vitamin E’s antioxidant properties aid in preventing the oxidation of LDL cholesterol, reducing the risk of heart disease.
  • Improving eye health: Vitamin E may help prevent age-related macular degeneration, a leading cause of blindness in older adults.
  • Promoting skin health: Vitamin E is often used topically for its moisturizing and anti-inflammatory properties. It can also help protect against UV damage and premature aging.
  • Supporting brain function: Vitamin E may play a role in cognitive health and has been linked to a reduced risk of Alzheimer’s disease.

Deficiency of Vitamin E

While deficiency of Vitamin E is relatively rare, it can lead to serious health issues, especially in individuals with specific genetic disorders or malabsorption issues. Symptoms of Vitamin E deficiency include:

  • Neuromuscular problems: These are characterized by muscle weakness, difficulties with coordination and balance (ataxia), and numbness in the extremities.
  • Immune system dysfunction: Vitamin E is essential for maintaining immune system health. Deficiency can lead to an increased susceptibility to infections.
  • Retinopathy: This is a progressive eye disorder that can lead to vision loss, caused by damage to the retina.
  • Cognitive problems: Severe vitamin E deficiency can even contribute to neurological and cognitive issues such as impaired reflexes, speech, and vision.

Prolonged deficiency of Vitamin E necessitates medical attention. It’s crucial to consult a healthcare provider if any of these symptoms are persistent, to ensure appropriate treatment and dietary adjustments.

Sources of Vitamin E

Vitamin E can be found in various food sources, including:

  • Plant oils (wheat germ oil, sunflower oil, safflower oil)
  • Nuts and seeds (almonds, peanuts, hazelnuts)
  • Green leafy vegetables (spinach, broccoli)
  • Avocados
  • Fortified cereals and dairy products
  • Supplements (consult a healthcare provider for dosage and recommendations)

It’s important to note that Vitamin E is a fat-soluble vitamin, meaning it requires the presence of fat to be absorbed by the body. Therefore, consuming it with healthy fats such as avocado or nuts can increase its absorption. Additionally, cooking foods containing Vitamin E can decrease their levels; opting for raw or lightly cooked sources is recommended.

Side Effects of Excess Vitamin E

While Vitamin E has many health benefits, excessive intake can also have adverse effects on the body. These include:

  • Increased risk of bleeding: High doses of Vitamin E can act as a blood thinner, increasing the risk of bleeding and bruising.
  • Nausea and diarrhea: Consuming too much Vitamin E can cause gastrointestinal discomfort, including nausea and diarrhea.
  • Reduced absorption of other vitamins: Excess Vitamin E can interfere with the absorption of other fat-soluble vitamins, such as Vitamin A and K.

It’s essential to stick to the recommended daily intake for Vitamin E, which is 15 mg for adults. Consult a healthcare provider before starting any supplements to ensure safe and appropriate dosages.

Vitamin E for Hair, Nails, and Skin

Vitamin E’s potent antioxidant and moisturizing properties make it a popular ingredient in hair, nail, and skincare products.

For Hair

Vitamin E can contribute to a healthy scalp and hair in several ways. It promotes circulation in the scalp, supporting hair growth. Its antioxidant properties help reduce oxidative stress and free radicals that can cause hair follicle cells to break down. Regular use of Vitamin E infused products or oils can add shine, prevent breakage, and reduce split ends.

For Nails

Vitamin E can also be beneficial for nail health. It can help combat yellow nail syndrome, a condition that can make nails turn yellow, thicken, and slow their growth rate. Applying Vitamin E oil on the nails can also prevent dryness and cracking, promoting stronger and healthier nails.

For Skin

Vitamin E is widely recognized for its skin benefits. It helps keep the skin hydrated and calm, thanks to its moisturizing and anti-inflammatory properties. Its antioxidant properties also protect the skin from damaging UV rays and environmental pollutants, reducing signs of aging. Vitamin E can help lighten scars, dark spots, and under-eye circles, promoting an even skin tone.

While Vitamin E can be beneficial for hair, nails, and skincare, it’s essential to do a patch test before applying new products containing Vitamin E, as some people might be sensitive to it. Always consult a dermatologist or other healthcare professional before starting any new skincare routine.

Daily Intake and Supplements for Vitamin E

The recommended daily intake for Vitamin E is 15 mg for adults. Pregnant and breastfeeding women may require slightly higher amounts, as directed by their healthcare provider.

If necessary, supplements can be used to meet the recommended intake levels. However, it’s important to consult a healthcare provider before starting any new supplement regime, especially if already taking other medications or if pregnant/breastfeeding.


Vitamin E is a vital nutrient that plays various roles in maintaining good health. Its antioxidant and anti-inflammatory properties make it a powerful tool in preventing chronic diseases, boosting the immune system, and supporting brain function. While Vitamin E deficiency is rare, incorporating it into our diets through food sources or supplements can provide numerous benefits. However, excessive intake of Vitamin E can have adverse effects, and it’s essential to stick to the recommended daily intake. Additionally, Vitamin E is a popular ingredient in hair, nail, and skincare products for its moisturizing and antioxidant benefits. Always consult a healthcare professional before starting any new supplements or skincare routine. So keep your body healthy by incorporating Vitamin E into your diet and enjoy its many benefits!
