What is Vitamin E?
Vitamin E, a fat-soluble vitamin vital for numerous bodily functions, is a powerful protector against free radicals. Our metabolism and environmental factors like smoke and radiation produce these harmful molecules. Unlike a physical shield, Vitamin E works behind the scenes, neutralizing these free radicals before they can damage our cells.
Beyond this crucial defense, Vitamin E plays a key role in maintaining healthy vision, reproduction, and the function of our blood, brain, and skin. Research suggests it may even contribute to managing metabolic disorders like obesity, diabetes, hypertension, and dyslipidemia.
Luckily, obtaining this essential vitamin is easy. Vitamin E is abundant in various foods, including vegetable oils (corn, cottonseed, soybean, safflower), wheat germ, whole-grain cereals, and leafy green vegetables. While cooking and storage can reduce its presence, a balanced diet ensures we receive adequate amounts.
Importance of Vitamin E
Vitamin E is of great importance to our health due to its various roles:

It enhances the activity of immune cells, such as T cells and macrophages, which play key roles in defending the body against infections. The antioxidant properties of vitamin E also contribute to immune health by neutralizing free radicals that can compromise the immune response. Ensuring sufficient levels of vitamin E is important for overall immune function and resilience against infections.
- Brain Function: Vitamin E contributes to healthy brain function. It is believed to protect brain cells from oxidative stress, which is implicated in neurodegenerative diseases. While research on vitamin E and cognitive function is ongoing, some studies suggest that it may have a role in reducing the risk of cognitive decline associated with aging. However, the relationship between vitamin E and brain health is complex, and more research is needed to fully understand its mechanisms and potential benefits.
It’s important to note that while vitamin E plays these roles in the body, individual responses may vary, and it’s always advisable to consult with healthcare professionals for personalized advice on vitamin E supplementation or dietary adjustments.
Genetics of Vitamin E Levels
Genetic variations play a significant role in determining individual vitamin E levels. These variations affect how our bodies absorb, transport, and utilize this crucial antioxidant. Understanding these genetic influences can revolutionize our approach to optimizing vitamin E levels, paving the way for personalized strategies and improved health outcomes.
BUD13, ZNF259(ZPR1), and APOA1/C3/A4/A5
The genetic variant rs964184, located on chromosome 11q23.3, has been associated with alpha-tocopherol levels. This locus is situated in a gene-rich region at gene ZNF259(ZPR1) and between gene BUD13, and the gene cluster APOA1/C3/A4/A5.
APOA1/C3/A4/A5 is known for its involvement in lipid metabolism and regulation. The presence of this SNP suggests a potential link between vitamin E levels and processes related to lipid metabolism.
Close to the BUD13 there is also another significant SNP for Vitamin E levels, rs12272004.
The replicated findings in this meta-analysis strengthen the found associations, emphasizing the significance of these genetic markers in influencing alpha-tocopherol concentrations. Further research may uncover the precise mechanisms by which these genes contribute to vitamin E regulation.
The genetic variant rs11057830, located on chromosome 12q24.31, represents another locus associated with alpha-tocopherol levels. This locus is situated near the SCARB1 gene, which plays a role in lipid metabolism and is involved in regulating cholesterol levels. Identifying this SNP suggests a potential connection between vitamin E levels and lipid-related processes mediated by SCARB1.
Exploring the specific interactions between SCARB1 and vitamin E metabolism may provide valuable insights into the regulatory pathways involved.
The genetic variant rs2108622, located on chromosome 19pter-p13.11, is another novel SNP associated with alpha-tocopherol levels. This locus is situated near the CYP4F2 gene, known for its role in metabolizing various compounds, including vitamin E. The identification of this SNP suggests a potential impact on vitamin E metabolism, influencing its circulating levels.
In the meta-analysis, the association with CYP4F2 was reaffirmed, highlighting the importance of this genetic marker in the context of vitamin E regulation. Further investigations into the specific interactions between CYP4F2 and vitamin E metabolism could provide valuable insights into the underlying mechanisms.
These genetic variants identified through GWAS shed light on the intricate relationship between genetics and the response to long-term vitamin E supplementation, providing valuable insights into personalized approaches to nutritional interventions.
Non-Genetic Factors Influencing Vitamin E Levels
It’s important to know that genes alone do not influence vitamin E levels – several other factors do as well. Below are some insights on what other components interact with vitamin E concentrations within our body.
Vitamin E is present in numerous food items, encompassing vegetables, fruits, meats, and animal products. Noteworthy sources include canola oil, olive oil, margarine, almonds, and peanuts.
Fat Absorption Mechanisms
As a fat-soluble vitamin, the absorption of vitamin E in the gastrointestinal tract is contingent upon processes governing fat absorption or metabolism. Consequently, individuals with conditions leading to fat malabsorption (e.g., Celiac disease, Crohn’s disease, pancreatic disorders) may experience a gradual deficiency in vitamin E over time.
Interaction with Other Nutrients
Deficiencies in iron and zinc can influence vitamin E metabolism and impede the transport of vitamin E stores from the liver to other body tissues.
Various health conditions can impact vitamin E levels. For instance, metabolic disorders like obesity, diabetes, hypertension, and dyslipidemia may influence vitamin E concentrations.
The dosage of vitamin E in supplements is another contributing factor. In the United States, the median daily intake of vitamin E from food typically ranges from 5 to 10 milligrams (mg). Vitamin E supplements commonly provide concentrations of 268 or 537 mg (equivalent to 400 or 800 international units).
Understanding these factors can help individuals and healthcare providers develop strategies to maintain optimal Vitamin E levels. However, it’s important to consult with a healthcare provider for personalized advice.
Signs of Vitamin E Deficiency
Vitamin E deficiency can manifest in several ways:
- Muscle Weakness: Vitamin E is essential to the central nervous system. Its deficiency can result in oxidative stress, leading to muscle weakness.
- Coordination and Walking Difficulties: A deficiency can cause certain neurons, called the Purkinje neurons, to break down, harming their ability to transmit signals.
- Numbness and Tingling: Damage to nerve fibers can prevent the nerves from transmitting signals correctly, resulting in these sensations, also known as peripheral neuropathy.
- Vision Deterioration: A vitamin E deficiency can weaken light receptors in the retina and other cells in the eye. This can lead to loss of vision over time.
- Immune System Problems: Some research suggests a lack of vitamin E can inhibit the immune cells.
- Retinopathy and Dry Skin: These are also reported signs of Vitamin E deficiency.
Please consult with a healthcare provider if you experience any of these symptoms. They can conduct a blood test to determine your vitamin E levels.
