Vitamin E is a fat-soluble vitamin with several forms, but only alpha-tocopherol is used by the human body. It is a vital nutrient for maintaining good health and is important for the eyes, skin, blood, brain, and the proper functioning of many organs. Vitamin E acts as an antioxidant, protecting cells from free radical damage, reducing inflammation, and improving immune function. It is naturally found in nuts, seeds, vegetable oils, and green vegetables, and can also be taken as a dietary supplement. While vitamin E deficiency is rare, it is important to include this vitamin in our diet to maintain optimal health and potentially prevent chronic diseases.

What You'll Learn
Vitamin E is an antioxidant, protecting cells from free radicals
Vitamin E is a fat-soluble vitamin with several forms, but the human body can only use alpha-tocopherol. Vitamin E is a nutrient required for good health, and one of its most important functions is to act as an antioxidant. This means that it protects cells from free radical damage.
Free radicals are molecules that can cause damage to cells, and they are produced by natural processes in the body and from external sources such as ultraviolet light and fluorescent light bulbs. Vitamin E can protect against this damage and reduce the production of free radicals. In the 1980s, scientists discovered that free radical damage was involved in the early stages of artery-clogging atherosclerosis and might also contribute to cancer, vision loss, and other chronic conditions.
Vitamin E has numerous other important roles within the body due to its antioxidant activity. It is important for the proper functioning of many of the body's organs, including the eyes, skin, blood, and brain. It also enhances immune function and prevents clots from forming in heart arteries.
Vitamin E is found in vegetable oils, nuts, seeds, and green vegetables. Most people can get enough vitamin E from a healthy diet, but supplements have become popular. However, the risks and benefits of these supplements are still unclear, and it is best to get vitamins from a balanced diet.

It enhances immune function and reduces inflammation
Vitamin E is a fat-soluble vitamin with antioxidant properties. It is the major lipid-soluble component in the cell antioxidant defence system, protecting cells from free radical damage. Free radicals are damaging molecules that may contribute to cancer, vision loss, and other chronic conditions.
Vitamin E enhances immune function by stimulating the body's defences and increasing phagocytic functions. It also reduces inflammation, which is a key contributor to many diseases. A study on murine acquired immunodeficiency syndrome (AIDS) showed that a 15-fold increase in dietary vitamin E normalised immune parameters altered in HIV/AIDS. Additionally, vitamin E protected against the side effects of azidothymidine, such as bone marrow toxicity.
Vitamin E is found in vegetable oils, nuts, seeds, and green vegetables. It is recommended to eat vitamin E-rich foods every day as part of a healthy diet. Supplements are also available, but they should be taken as directed by a doctor.
Vitamin E deficiency is rare, but it can occur in people with digestive disorders or those who don't absorb fat properly. Deficiency symptoms include bleeding in the brain, eye problems, and a form of anaemia where red blood cells rupture.

Vitamin E is good for the eyes, skin, blood and brain
Vitamin E is a potent antioxidant that exists in different forms, with alpha-tocopherol being the form that best meets our needs. Vitamin E plays an important role in protecting the body from oxidative stress and supporting the immune system. It is commonly found in nuts and seeds, which also provide fibre, healthy fats, minerals, and other essential vitamins. Vitamin E is good for the eyes, skin, blood, and brain and can be consumed through dietary sources or supplements.
Vitamin E is beneficial for eye health, particularly in protecting against oxidative damage, which can lead to cataracts and age-related macular degeneration. The Age-Related Eye Disease Study (AREDS) found that vitamin E helped reduce the risk of advanced age-related macular degeneration by 25% in those with early signs of the condition. Additionally, the alpha-tocopherol form of vitamin E, along with lutein and zeaxanthin, may decrease the risk of cataracts. However, it is important to note that some studies have not found a significant link between vitamin E and vision health, so further research is needed.
Vitamin E is also beneficial for skin health and is commonly found in skincare products and supplements. It acts as an antioxidant, helping to protect skin cells from damage and keeping the skin moisturized. Vitamin E is found naturally in sebum (skin oil), which creates a barrier to lock in moisture. While it may not make wrinkles disappear or prevent sunburn, applying products containing vitamin E can benefit dry skin. Consuming vitamin E in the right amounts may also help protect the skin from environmental stressors.
In terms of blood health, vitamin E can thin the blood, which may increase the risk of a hemorrhagic stroke. Therefore, it is important for individuals taking blood-thinning medications to consult their doctors before taking vitamin E supplements.
Finally, vitamin E may play a role in brain health and cognitive function. Its antioxidant properties have been linked to slowing down the progression of dementia, particularly in the early stages of mild cognitive impairment (MCI). However, more research is needed to fully understand the role of vitamin E in cognitive decline and its potential benefits for individuals with Alzheimer's disease or other cognitive conditions.

It may help with period pain and premenstrual symptoms
Vitamin E is a fat-soluble vitamin with several forms, but the human body only uses alpha-tocopherol. It acts as an antioxidant, scavenging loose electrons and reducing free radical damage. This damage is involved in the early stages of artery-clogging atherosclerosis and may contribute to cancer, vision loss, and other chronic conditions.
Vitamin E is also an anti-inflammatory and can improve immune function. It can help prevent clots from forming in heart arteries. Vitamin E is found in nuts and seeds, which also provide fibre, healthy fats, minerals, and essential vitamins.
Vitamin E has been found to reduce period pain and premenstrual symptoms. Period pain is often characterised by an increased concentration of prostaglandins (hormone-like substances) in menstrual fluid, and suppressing its production has become the primary way to treat menstrual pain. Vitamin E can inhibit the release of arachidonic acid (a fatty acid) and its conversion to prostaglandin, ultimately reducing period pain.
A 2021 study showed that supplementing with a combination of vitamin E and vitamin C daily for eight weeks helped reduce the severity of pelvic pain and dysmenorrhea in women with endometriosis. Experts recommend individuals focus on incorporating vitamin E-rich foods into their diet before taking supplement pills. However, a conversation with a healthcare professional will be beneficial in understanding how supplement pills may help meet specific needs.

Vitamin E is found in nuts, seeds, and green vegetables
Vitamin E is a fat-soluble nutrient with several forms, but alpha-tocopherol is the only one used by the human body. Its main role is to act as an antioxidant, protecting the body from free radicals, reducing inflammation, and improving immune function.
Some green vegetables that are high in vitamin E include red sweet peppers, turnip greens, beet greens, spinach, and butternut squash. Butternut squash, in particular, contains 1.29 mg of vitamin E per 100 g serving, as well as plenty of other vitamins and nutrients.
Overall, vitamin E is widespread in foods, and deficiency is rare. However, disorders that affect the absorption of fat, such as cystic fibrosis or liver disease, can lead to vitamin E deficiency over time.
