What is vitamin E?
Vitamin E is a fat-soluble nutrient and an important antioxidant that helps to protect cells from damage caused by free radicals. It exists in eight different forms, but alpha-tocopherol is the most active and most commonly found in the human body. Here are some of the key benefits associated with vitamin E:
Antioxidant properties
Vitamin E is a potent antioxidant that helps protect cells from the damaging effects of free radicals, which can lead to oxidative stress and damage to DNA and other cellular structures. This can contribute to chronic diseases such as cancer, heart disease, and Alzheimer’s disease. Studies have found that vitamin E supplements may help to reduce the risk of certain types of cancer, including lung and prostate cancer.
Skin health
Vitamin E plays an important role in maintaining healthy skin. It helps to regulate the production of sebum, the oily substance that moisturizes the skin and hair. Vitamin E also helps to reduce inflammation in the skin and promote wound healing. Studies have also found that vitamin E may help to protect against UV damage from the sun, which can contribute to skin aging and wrinkles.
Immune system support
Vitamin E is involved in regulating immune function. Studies have found that vitamin E supplements may help to reduce the risk of respiratory infections and other diseases that affect the immune system.
Heart health
Vitamin E has been linked to a reduced risk of heart disease. It may help to prevent the formation of plaque in the arteries and improve blood vessel function.
Eye health
Vitamin E may help to reduce the risk of age-related eye diseases such as cataracts and macular degeneration. Studies have found that vitamin E supplements may help to slow the progression of these diseases and improve vision.
Anti-inflammatory properties
Vitamin E has been shown to have anti-inflammatory effects, which may help to reduce the risk of chronic diseases that are associated with inflammation, such as arthritis and diabetes. Studies have found that vitamin E supplements may help to reduce inflammation in people with these conditions.
Signs of Vitamin E deficiency
Vitamin E deficiency is relatively rare and most commonly occurs in individuals with fat malabsorption disorders or in individuals who follow a diet that is severely low in fat. Here are some signs and symptoms that may occur if you have a vitamin E deficiency:
- Muscle weakness
- Balance problems
- Vision problems
- Skin issues
- Weakened immune system
- Poor cognitive function
Good sources of vitamin E:
- Nuts and seeds: Almonds, sunflower seeds, hazelnuts, pine nuts, peanuts, and pumpkin seeds are all good sources of vitamin E. One ounce of almonds contains about 7.3 milligrams of vitamin E
- Oils: Vegetable oils such as wheat germ oil, sunflower oil, and safflower oil are good sources of vitamin E. One tablespoon of wheat germ oil contains about 20.3 milligrams of vitamin E
- Leafy green vegetables: Spinach, kale, and collard greens are all good sources of vitamin E. One cup of cooked spinach contains about 3.7 milligrams of vitamin E
- Fortified foods: Many breakfast cereals and other packaged foods are fortified with vitamin E. Check the nutrition label to find out how much vitamin E is in the product
- Avocado: One medium avocado contains about 4.2 milligrams of vitamin E
- Fish: Some fish, such as salmon and trout, are good sources of vitamin E. One 3-ounce serving of salmon contains about 1.5 milligrams of vitamin E
Fruits: Mangoes, kiwifruit, and papayas are all good sources of vitamin E. One medium-sized mango contains about 1.1 milligrams of vitamin E
It’s important to note that while there is evidence to support the potential health benefits of vitamin E, more research is needed to fully understand its effects on various health conditions. In addition, excessive intake of vitamin E can be harmful, so it’s important to talk to a healthcare provider before taking any supplements or making significant changes to your diet.
