What is vitamin E?
Vitamin E is a fat-soluble compound that includes eight different isotypes: four tocopherols and four tocotrienols. Each of these isotypes has its own unique characteristics and benefits, but in general, vitamin E is known for its potent antioxidant action.
Sources of vitamin E
Vitamin E is found naturally in a variety of foods, mainly in vegetable oils such as olive oil, sunflower oil, wheat germ oil and canola oil. Other good sources include nuts and seeds, such as almonds and sunflowers, and to a lesser extent in green leafy vegetables and some fruits such as avocado and kiwi.
Understanding the function and sources of vitamin E is the first step in integrating this important nutrient into your diet effectively, which can have a significant impact on preventing ageing and improving overall health.
Benefits of vitamin E in the face of ageing
Vitamin E offers multiple benefits that can help counteract the effects of ageing in both physical and functional aspects. Here we explore some of the most significant:
- Skin protection: Vitamin E is crucial for maintaining the integrity of the skin, helping to prevent damage caused by exposure to UV rays. This can result in less appearance of wrinkles and fine lines, and skin that remains more elastic and healthy over time.
- Cardiovascular health: One of the most important benefits of vitamin E is its ability to improve cardiovascular health. By preventing the oxidation of LDL cholesterol, it helps reduce the risk of atherosclerosis, which is vital for preventing conditions such as heart attacks and strokes.
- Brain function: Vitamin E plays an important role in protection against cognitive degeneration. Adequate vitamin E intake is associated with a lower risk of developing neurodegenerative diseases such as Alzheimer’s and other forms of dementia.
- Immune system health: The strength of the immune system often declines with age, but vitamin E can help maintain a robust immune system, crucial for protecting the body from infection and disease.
- Eye health: Vitamin E contributes to the prevention of age-related eye diseases, such as macular degeneration and cataract.
These benefits make vitamin E an essential component of any nutrition strategy aimed at combating the signs of ageing and maintaining good health as you age. Incorporating vitamin E-rich foods or considering supplementation under medical supervision can be an excellent way to take advantage of these benefits.
Fuentes de vitamina E
Para aprovechar los beneficios de la vitamina E en la lucha contra el envejecimiento y mejorar la salud general, es importante conocer y consumir alimentos ricos en este nutriente. La vitamina E se encuentra principalmente en una variedad de alimentos vegetales y algunos productos animales. Aquí detallamos las principales fuentes:
- Aceites vegetales: Los aceites como el de aceite de oliva virgen extra, germen de trigo, girasol, almendra y avellana son algunas de las fuentes más ricas en vitamina E. Usar estos aceites en ensaladas o para cocinar a bajas temperaturas puede ser una excelente manera de aumentar la ingesta de vitamina E.
- Frutos secos y semillas: Alimentos como las almendras, nueces, semillas de girasol y piñones contienen cantidades significativas de vitamina E. Incorporar estos alimentos en su dieta diaria, ya sea como snacks, en ensaladas o en platos principales, es una forma práctica de obtener este antioxidante esencial.
- Verduras de hoja verde: Las verduras como la espinaca, acelga y el kale también aportan vitamina E, además de una variedad de otros nutrientes importantes.
- Frutas: Algunas frutas como el kiwi, mango y aguacate son fuentes moderadas de vitamina E y pueden complementar la ingesta obtenida de otras fuentes.

Intake recommendations
To maximise the benefits of vitamin E and support overall wellbeing, it is essential to follow appropriate intake recommendations. Here we provide detailed guidance on how much vitamin E you should consume, depending on your age, gender and other specific needs.
- Recommended daily allowance: The recommended daily intake (RDA) of vitamin E varies according to age and gender. For adults, the generally recommended RDI is approximately 15 milligrams of alpha-tocopherol per day, which is the most active form of vitamin E in the human body.
- Pregnant or breastfeeding women: Pregnant or breastfeeding women may need a slightly higher amount, around 19 milligrams per day, to support their additional needs and those of their baby.
- Children and adolescents: Children also have specific requirements that vary by age. For example, children aged 1-3 years need approximately 6 milligrams per day, while adolescents need about 11 milligrams per day.
- Older people: As people age, their ability to absorb vitamins may decrease, so maintaining an adequate intake of vitamin E is crucial to protect against cellular ageing and maintain strong immune functions.
Tips for optimising vitamin E absorption
- Include sources of healthy fat in your diet: Vitamin E is fat-soluble, which means that its absorption is most effective when consumed alongside sources of fat. Adding a little olive oil to leafy green vegetables or having a handful of nuts with fruit can help improve vitamin E absorption.
- Variety in the diet: Consuming a wide variety of foods rich in vitamin E is the best way to ensure an adequate intake of all forms of vitamin E and other antioxidants that can work together to improve overall health.
By following these recommendations, you can ensure you get enough vitamin E to take advantage of its antioxidant and ageing-supporting benefits, while maintaining a healthy balance in your diet.
Precautions and advice
Although vitamin E is crucial for health and offers many benefits, especially in terms of anti-ageing, it is important to be aware of some precautions when increasing your intake, either through diet or supplementation.
Potential toxicity and side effects
- Excessive consumption: Although rare, consuming vitamin E in very high doses can lead to complications such as bleeding due to its anticoagulant effect. The recommended upper daily intake for adults is approximately 1,000 milligrams (1,500 IU) of alpha-tocopherol per day.
- Symptoms of toxicity: Symptoms of vitamin E toxicity may include nausea, diarrhoea, headaches, fatigue and blurred vision, as well as an increased risk of bleeding.
Drug interactions
- Anticoagulant medications: Vitamin E may enhance the effect of anticoagulant medications such as warfarin, increasing the risk of bleeding. If you are taking this type of medication, it is essential to consult a healthcare professional before modifying your vitamin E intake.
- Other medications: It may also interact with cholesterol-lowering drugs and some cancer treatments. Medical supervision is crucial to avoid adverse interactions.
