Causes of Vitamin E Deficiency
Vitamin E deficiency can result from various factors ranging from dietary habits to genetic disorders. The most common causes include isolated vitamin e deficiency, inadequate dietary intake, malabsorption disorders, genetic conditions, premature birth, liver disease, digestive system surgeries, and chronic fatigue or inflammation.
Each of these factors can significantly impact your body’s ability to maintain adequate Vitamin E levels, leading to a host of health issues.
Let’s delve deeper into each cause to understand how they contribute to this deficiency.
1. Inadequate Dietary Intake
A diet lacking in Vitamin E-rich foods is a primary cause of deficiency.
Many foods that are excellent sources of Vitamin E include:
- Vegetable oils
- Nuts
- Seeds
- Leafy vegetables
However, some common diets may not include enough of these foods rich, leading to inadequate intake. This issue is particularly prevalent in countries with high rates of food insecurity, where access to Vitamin E-rich foods is limited.
People who follow restrictive diets or have limited access to diverse food sources are at a higher risk of developing Vitamin E deficiency.
2. Malabsorption Disorders
Certain health conditions can impair the body’s ability to absorb fat, which in turn affects Vitamin E absorption. Disorders such as Celiac disease, Crohn’s disease, and cystic fibrosis are notable examples. In developed countries, vitamin E deficiency is usually caused by such disorders that impair fat absorption. These conditions disrupt the normal process of fat absorption and fat malabsorption, leading to a deficiency in fat-soluble vitamins like Vitamin E.
Consequently, even if a person’s diet includes enough Vitamin E, their body’s ability may not be able to absorb and utilize it effectively.
3. Genetic Disorders
Genetic disorders can also lead to Vitamin E deficiency. One such condition is the deficiency of the alpha-tocopherol transfer protein (aTTP), which is crucial for Vitamin E metabolism. Additionally, rare genetic conditions like abetalipoproteinemia hinder the body’s ability to transport Vitamin E.
These genetic anomalies disrupt the normal processing and distribution of Vitamin E, leading to severe deficiencies.
4. Premature Birth
Premature infants are at a higher risk of Vitamin E deficiency due to their low reserves and insufficient transfer of the vitamin from the placenta. These infants often require additional Vitamin E to support their rapid growth and development.
If left untreated, Vitamin E deficiency in premature infants can lead to serious health complications.
5. Liver Disease
Liver disease can significantly impact Vitamin E levels. Conditions such as cirrhosis or hepatitis affect the liver’s ability to store and metabolize Vitamin E. Since the liver plays a crucial role in processing this fat-soluble vitamin, any impairment can lead to deficiency.
People with chronic liver diseases often experience reduced Vitamin E levels, which can exacerbate their health issues.
6. Digestive System Surgeries
Surgeries involving the digestive system, such as weight loss surgery, can affect the body’s ability to absorb Vitamin E. Post-surgical factors can lead to malabsorption, contributing to a deficiency in this essential nutrient.
Patients undergoing these procedures need to be monitored for potential Vitamin E deficiency and may require supplementation to maintain adequate levels.
7. Chronic Fatigue or Inflammation
Chronic inflammatory conditions can lead to decreased absorption of Vitamin E. Health issues like chronic fatigue syndrome and ongoing inflammation adversely affect the body’s ability to maintain adequate Vitamin E levels. These conditions not only impact overall health but also increase the risk of developing Vitamin E deficiency.
Symptoms of Vitamin E Deficiency
Vitamin E deficiency manifests through a variety of symptoms, ranging from mild to severe. These symptoms include:

Lower limb areflexia and cardiac arrhythmias are also common neurological symptoms associated with this deficiency.
2. Vision Problems
Vision problems are another significant symptom of Vitamin E deficiency. Low levels of this vitamin can lead to retinopathy, characterized by abnormal blood vessel growth in the eyes. In severe cases, individuals may experience blurred vision or even blindness. Recognizing these symptoms early can prevent long-term damage to your vision loss.
3. Immune System Weakness
Vitamin E plays a vital role in maintaining a healthy immune system. A deficiency can weaken the body’s ability to fight off infections, making individuals more susceptible to illnesses. This increased vulnerability can lead to frequent infections and slower recovery times, highlighting the importance of adequate Vitamin E levels for a strong immune response.
4. Skin Issues
Vitamin E deficiency can lead to various skin issues, including dry, rough skin, and irritation. This vitamin is essential for maintaining healthy skin, and its absence can result in noticeable skin problems.
Adequate Vitamin E intake is crucial for maintaining skin health and overall well-being.
5. Muscle and Coordination Problems
Deficiency in Vitamin E can significantly affect muscles and motor skills. Individuals may experience muscle weakness, loss of muscle mass, and difficulty with coordination. These symptoms can impact daily activities and overall quality of life, making it essential to address Vitamin E deficiency promptly.
6. Anemia
Vitamin E deficiency can contribute to oxidative stress, leading to hemolytic anemia. This condition is characterized by the breakdown of red blood cells, resulting in symptoms like fatigue and pale skin. Anemia further complicates the health issues associated with Vitamin E deficiency, necessitating timely intervention.
7. Increased Risk of Chronic Diseases
Long-term Vitamin E deficiency can increase the risk of chronic diseases such as heart disease, cancer, and diabetes. Studies suggest that low Vitamin E levels are associated with these serious health conditions, highlighting the importance of maintaining adequate levels to prevent long-term complications.
Diagnosing
Diagnosing Vitamin E deficiency involves measuring serum alpha-tocopherol levels, the most direct method for confirming the deficiency. Blood tests are commonly used to assess Vitamin E levels and identify any abnormalities. These tests can provide a clear indication of whether an individual is suffering from Vitamin E deficiency.
In addition to blood tests, diagnosis can be based on symptoms and physical examination results. Conditions like cystic fibrosis and chronic liver diseases can lead to Vitamin E deficiency by impairing fat absorption.
For accurate diagnosis, especially in adults with abnormal lipid levels, a ratio of serum alpha-tocopherol to serum lipids is critical. Diagnosis of vitamin E deficiency is based on measuring this ratio, as it provides a more precise assessment of Vitamin E status. This comprehensive approach ensures that Vitamin E deficiency is accurately identified and treated.
Treatment Options
Vitamin E deficiency is primarily treated with a vitamin e supplement. These supplements help restore the body’s Vitamin E levels.
These supplements can come in the form of alpha-tocopherol or mixed tocopherols, both of which are effective in restoring adequate Vitamin E levels. The recommended daily amount for adults is 15 milligrams, but this can vary based on individual needs and specific health conditions. For example, patients with chronic cholestasis may require a dosage of 15 to 25 IU/kg per day, while those with cystic fibrosis might need between 5 to 10 IU/kg daily.
In cases where oral vitamin supplementation is not possible due to intestinal issues, Vitamin E can be administered via intramuscular injections. For severe deficiencies like abetalipoproteinemia, higher doses ranging from 100 to 200 IU/kg per day may be necessary.
Mixed tocopherols can also be administered at a dosage of 200 IU. These treatments help to quickly restore Vitamin E levels, alleviating deficiency symptoms and preventing further health complications.
