What is Vitamin E ?

The body requires the fat-soluble vitamin vitamin E for a variety of vital processes. It also promotes a number of important physiological processes in the body in addition to acting as an antioxidant.1Overview | Researched based study from

It occurs naturally in many foods and is also available as supplements.

The body uses vitamin E, a fat-soluble vitamin, for a number of essential functions.


Facts on vitamin E

  • Researchers at the University of California, Berkeley made the discovery of it in 1922.
  • Eight distinct substances, including four tocopherols and four tocotrienols, make up vitamin E.
  • As a potent antioxidant, it is frequently used in skincare products.
  • Being a fat-soluble vitamin, it is stored in the body’s fatty tissues and, if taken in excess, can accumulate to hazardous levels.


Benefits of vitamin E

Excellent antioxidant

  • In the body, it mostly serves as an antioxidant.
  • Its primary function is to shield cells from harm from dangerous substances called free radicals, which may cause oxidative stress and be a factor in chronic illnesses including cancer, heart disease, and dementia.1Biological role | Researched based study from

Immune system support

  • By encouraging the creation of white blood cells that fight against infection and illness, it helps to strengthen the immune system.

Skin health

  • It is thought to aid in defending the skin against pollutants and UV radiation damage. By lowering inflammation and encouraging collagen formation, it is also believed to delay the ageing process of the skin.1Biological role | Researched based study from
  • Additionally, it could hydrate the skin and make wrinkles and fine lines less obvious.

Eye health

  • It could aid in preventing age-related macular degeneration, which is one of the main factors in visual loss in older people.

Cardiovascular health

  • It has been demonstrated that by enhancing blood flow and lowering inflammation, it can aid in the prevention of blood clot formation and lower the risk of heart disease.

Brain function

  • Additionally, it could help keep people’ cognitive abilities intact and lower their risk of cognitive decline.1Biological role | Researched based study from

  • Such as oats, brown rice, and whole grains like wheat.


  • Several fruits, including papaya, kiwi, and mangoes, have trace quantities of vitamin E. 1Sources | Researched based study from

Animal based sources are

Egg whites

  • One big egg provides almost 6% of the daily necessary amount of egg yolks, which makes them a decent source.


  • Beef liver, chicken liver, and other organ meats are good sources of the recommended daily allowance, with a 3-ounce portion of beef liver providing around 10% of that amount.1Sources | Researched based study from


  • There are small amounts in several fish varieties, including trout, salmon, and herring.


  • Sources include chicken, pig, and beef, however the quantity varies depending on the cut of meat.1Sources | Researched based study from


Risk factors for vitamin E deficiency

In healthy people who eat a balanced, diverse diet, vitamin E deficiency is uncommon. On the other hand, some medical disorders, such as:

Disorders of fat absorption

  • The body’s capacity to absorb dietary fat can be impacted by illnesses including Crohn’s disease, cystic fibrosis, and liver disease.2Risk factors | Researched based study from

Low-fat diets

  • The shortage can also be brought on by extremely low-fat diets or diets that drastically limit fat consumption.

Genetic disorders

  • Deficiency may also result from rare hereditary conditions that alter the metabolism of vitamin E.2Risk factors | Researched based study from

What are the symptoms of Vitamin E deficiencies?

  • Weakened muscles-Loss of muscle mass and muscular wasting might result from the shortage.
  • Poor coordination-It can have an impact on the neurological system and lead to balance and coordination issues.
  • Vision issues-A lack of vitamin E can harm the retina, resulting in vision issues like blurry vision in low light and loss of peripheral vision.2Symptoms | Researched based study from
  • Anemia-A condition when the body doesn’t have enough red blood cells to carry oxygen to the tissues.2Symptoms | Researched based study from
  • Immune system impairment-It can make the immune system less effective thus rendering infections more likely.
  • Skin conditions-It may result in scaly, rough, and dry skin.
  • Nerve damage-It is possible for nerve injury to take place, which can cause pain, tingling, and numbness in the hands and feet.2Symptoms | Researched based study from


What are the various forms of vitamin E?

There are eight distinct forms of it in nature, which may be further broken down into tocopherols and tocotrienols.

  • Alpha tocopherol is the most common and physiologically active form of vitamin E.
  • Gamma-tocopherol, which is frequently present in foods and has particular anti-inflammatory qualities, is another.4Forms | Researched based study from

To obtain the maximum advantage from supplements, it’s crucial to select a combination of these kinds while shopping. Physically, it can be found in the following forms:

  • Soft gels or capsules-supplements are frequently offered for sale as soft gels or capsules that may be swallowed.4Forms | Researched based study from
  • Drops of liquid-additionally, it is offered in liquid form, which may be mixed with food or beverages.
  • Oils or topical creams-its moisturizing and antioxidant characteristics make it a popular ingredient in skincare products like creams and oils.
  • Foods fortified-it is frequently added to meals to boost their nutritious content, such as breads, morning cereals, and plant-based milk substitutes.4Forms | Researched based study from
  • Multivitamin supplements-it may be found in multivitamin products, which combine vitamins and minerals. 4Forms | Researched based study from


Recommended dosage

  • Babies (0–6 months): 4 mg per day.
  • 7–12 month old infants: 5 mg per day.
  • Children (ages 1-3): 6 mg per day.

  • For adults (19 years of age and older): 15 mg daily.1Dosage | Researched based study from


Overdose signs

For adults, 1000 mg per day is the safe upper ingestion limit. Overdosing is possible if you take in more than this.5Overdose | Researched based study from

Overdose symptoms might include

  • Nausea
  • Diarrhea
  • Fatigue
  • Headache
  • Blurred vision
  • Bleeding

A significant vitamin E excess may cause a stroke and hemorrhage.

If you believe that you or someone you know has overdosed, get straight to the hospital.5Overdose | Researched based study from


Medicine-related interactions

Blood-thinning drugs, such as warfarin

  • These drugs’ effects may be enhanced by vitamin E, which also raises the risk of bleeding. 3Interactions | Researched based study from

Cholesterol-lowering medications, such as statins

  • Vitamin E could lessen the impact, which might raise cholesterol levels.

Drugs for chemotherapy

  • The supplements may lessen the efficiency of chemotherapy drugs, making them less efficient in killing cancer cells.3Interactions | Researched based study from

Immunosuppressive medications, such as cyclosporine

  • May become less effective, which might increase the risk of organ rejection in transplant recipients.3Interactions | Researched based study from


Key Takeaways
