Your body uses vitamin E for multiple purposes, including protecting you from oxidative stress and supporting your immune system. You can get vitamin E from certain foods and dietary supplements.

Vitamin plays many roles in your body, including:

  • protecting your cells from oxidative damage by neutralizing harmful molecules called free radicals
  • supporting proper immune function
  • promoting cellular signaling and metabolic processes

Vitamin E exists naturally in certain foods, including:

  • seeds
  • nuts
  • some vegetables
  • some fortified products

This article explores the 8 potential benefits and risks of vitamin E and how to get it through your diet.

Vitamin E in food vs. in supplements

According to The Dietary Guidelines for Americans 2020–2025, it’s best to get the Recommended Daily Allowance (RDA) of vitamins and nutrients through a balanced and nutritious diet.

This is for many reasons, including:

  • Whole foods may contain other beneficial nutrients, such as fiber and protein.
  • People who eat plant-based foods high in vitamin E may eat these instead of ultra-processed foods and foods with low nutritional value.
  • High amounts of vitamin E, common in supplements, may have adverse health effects.

However, some people, including those with certain dietary restrictions or following low-calorie eating plans, may need supplements to address a vitamin deficiency.

Note that most research on the effects of vitamin E uses supplements to determine the health effects of increasing vitamin E consumption.

Getting enough vitamin E may help prevent oxidative stress and cellular damage.

Oxidative stress occurs when there’s an imbalance between your body’s antioxidant defenses and the production and accumulation of compounds called reactive oxygen species (ROS). This can lead to cellular damage and increased disease risk. Oxidative stress can increase the risk of:

  • cancer
  • heart disease
  • eye disorders
  • cognitive decline

Because vitamin E is a powerful antioxidant in the body, research suggests supplementing with high doses may reduce markers of oxidative stress and boost antioxidant defenses in certain populations.

For example, a 2018 study in 54 people with kidney damage caused by high blood sugar (diabetic nephropathy) found that supplementing with 800 IU of vitamin E per day for 12 weeks significantly increased levels of glutathione peroxidase (GPx) compared with a placebo.

GPx is a group of antioxidant enzymes that protect cells from oxidative damage.

A 2021 study suggests that supplementing with a combination of vitamin E and vitamin C daily for 8 weeks reduced markers of oxidative stress, such as malondialdehyde and ROS, in female participants with endometriosis.

However, in certain other populations, high doses of vitamin E supplements may increase the risk of other health conditions, including:

  • bleeding and hemorrhagic stroke
  • prostate cancer
  • all-cause mortality

The risk of these adverse effects has not been found with vitamin E consumed in food.

Having high blood pressure and high levels of blood lipids such as LDL (bad) cholesterol and triglycerides may increase your risk of developing heart disease.

Research suggests that vitamin E supplements may help reduce certain heart disease risk factors in some people, but more studies are still needed to support their use.

A 2019 review of 18 studies found that, compared with placebo treatments, vitamin E supplements significantly reduced systolic but not diastolic blood pressure, the top and bottom numbers of blood pressure readings, respectively.

Some studies also suggest that taking vitamin E with omega-3 supplements may reduce LDL and triglyceride levels in people with metabolic syndrome. Metabolic syndrome is a cluster of conditions, including high blood fat levels, that increases the risk of heart disease and other health conditions.

In 2022, the US Preventive Services Task Force released a statement recommending against using vitamin E supplements to prevent cardiovascular disease or cancer. The Task Force noted that vitamin E supplements did not reduce cardiovascular disease or death due to cardiovascular disease.

According to 2022 research, eating nuts and seeds, both high in vitamin E, is associated with improved cardiovascular health. It is also associated with a reduced risk of metabolic syndrome, diabetes, and some types of cancer.

NAFLD includes several conditions that cause an accumulation of fat in the liver in people who drink little or no alcohol.

According to research findings, vitamin E supplements may improve some aspects of health in people with NAFLD.

A 2021 review of eight studies found that supplementing with vitamin E reduced levels of the liver enzymes alanine aminotransferase (ALT) and aspartate aminotransferase (AST), decreased blood lipid levels, and improved liver health in people with NAFLD.

Elevated AST and ALT levels can indicate liver inflammation and damage in people with NAFLD, so lower levels are favorable.

Dysmenorrhea is a condition characterized by severe and frequent menstrual pain, such as cramps and pelvic pain.

Promisingly, research suggests vitamin E supplements may reduce pain in women with this condition.

In a 2018 study in 100 women with dysmenorrhea, taking 200 IU of vitamin E daily relieved menstrual pain more than a placebo. The effects were even better when combining the vitamin with an omega-3 supplement containing 180 mg of EPA and 120 mg of DHA.

Additionally, a 2021 study showed that supplementing with a combination of vitamin E and vitamin C daily for 8 weeks helped reduce the severity of pelvic pain and dysmenorrhea in women with endometriosis.

Vitamin E supplements have also been linked to several other potential health benefits:

May benefit skin health

Vitamin E supplements may be helpful for those with certain skin disorders, such as eczema and psoriasis. However, the research is currently limited, and more studies are needed to support this potential benefit.

May benefit cognitive health

Maintaining optimal vitamin E levels and taking supplements may help prevent cognitive decline. However, it’s still unclear whether the supplements benefit people with cognitive conditions like Alzheimer’s disease.

May benefit older adults

Because vitamin E plays important roles in health, such as reducing inflammation and improving immune function, increased intake may benefit people with increased needs or don’t get enough in their diets. This may include older adults.

May improve lung function

A small 2019 study suggests vitamin E supplements could improve lung function and certain asthma symptoms in adults. The results of an older 2014 study suggest vitamin E could have a similar benefit for children with asthma. However, additional studies are still needed to better support these findings.

In a 2019 study, having adequate levels of vitamin E in the bloodstream is associated with a reduced risk of lung cancer in males with a history of smoking cigarettes. An older study from 2017 also linked higher dietary intake of vitamin E, measured by the amount in the bloodstream, with better lung function in male participants.

If you’re looking to increase your intake of vitamin E-rich foods, here are a few good options:

FoodServingVitamin E
wheat germ oil1 tablespoon (14 mL)135% of the Daily Value (DV)
dry-roasted sunflower seeds1 ounce (28 grams)49% of the DV
dry-roasted almonds1 ounce (28 grams)45% of the DV
peanut butter2 tablespoons (28 mL)19% of the DV
boiled spinach1/2 cup (112 grams)13% of the DV
boiled broccoli1/2 cup (46 grams)8% of the DV
kiwi1 medium (69 grams)7% of the DV
mango1/2 cup (82 grams)5% of the DV
tomato1 medium (123 grams)5% of the DV

Remember that the best way to get enough vitamin E in your diet is to consume various nutritious foods daily, including vegetables, fruits, nuts, and seeds.

Vitamin E deficiency in otherwise healthy individuals is uncommon, as most people get enough from their diet.

The adequate daily intake of vitamin E is:

AgeNon-pregnant, non-lactating individualsPregnant individualsLactating individuals
0–6 months4 mg
7–12 months5 mg
1–3 years6 mg
4–8 years7 mg
9–13 years11 mg
14+ years15 mg15 mg19 mg

Vitamin E deficiency

While vitamin E deficiency is generally rare, it’s more common in certain populations.

For example, people with medical conditions associated with fat malabsorption, including cystic fibrosis and Crohn’s disease, are at an increased risk.

Additionally, those with certain rare inherited diseases, such as abetalipoproteinemia, are more likely to have a deficiency.

Consuming too much vitamin E from food is unlikely. However, it is possible to consume too much vitamin E through supplements, which can lead to negative side effects and harm to your health.

Studies suggest that vitamin E supplements may increase the risk of prostate cancer in healthy people with prostates.

High dose vitamin E supplements may also increase the risk of bleeding, as well as hemorrhagic stroke.

The Tolerable Upper Intake Level (UL) for supplemental vitamin E is currently set at 1,000 mg daily. However, health concerns, including a possible risk of increased mortality, are associated with doses much lower than the UL. Therefore, you should generally not supplement with vitamin E unless a qualified healthcare professional recommends it and monitors your intake.

Remember that vitamin E supplement doses vary significantly, with some providing much more than a healthy person needs daily. Therefore, check the labels of vitamin supplements carefully and select supplements from brands that submit their products for third-party verification.

Interactions with medication

Vitamin E can potentially interact with certain medications.

While a few examples are listed below, it’s always important to talk with a healthcare professional about the supplements you’re taking, especially before they start you on prescription medication.

Vitamin E may have negative interactions with:

  • anticoagulant and antiplatelet medications
  • simvastatin and niacin
  • chemotherapy and radiotherapy

Vitamin E is an important fat-soluble nutrient. It’s a powerful antioxidant and is needed for immune health and cellular signaling in your body.

Some studies show that taking vitamin E supplements may benefit certain populations, including people with diabetic nephropathy and NAFLD.

However, supplements are often unnecessary because most people get enough vitamin E through their diet.

High doses of vitamin E supplements can cause side effects and interact with certain medications.

If you’re considering adding more vitamin E to your diet, talk with a healthcare professional about your specific health concerns first.

Just one thing

Try this today: Nuts and seeds are some of the richest dietary sources of vitamin E. These crunchy foods also provide fiber, healthy fats, minerals, and essential vitamins. To increase your vitamin E intake, try snacking on a trail mix made with almonds and sunflower seeds or enjoying fruit with nut or seed butter.
