Recognizing Vitamin E Deficiency: The Overlooked Risk That Can Impair Your Vision

Many people focus on maintaining sufficient levels of commonly discussed vitamins such as C and D to stay healthy. However, vitamin E is frequently overlooked despite its critical role in overall wellness. A deficiency in vitamin E can lead to severe health issues, particularly affecting the nervous system and vision.

Vitamin E is a powerful antioxidant that protects cells from damage caused by free radicals—unstable molecules that can harm cellular structures. Without enough vitamin E, the immune system struggles to defend against infections and illnesses.

Typically, a balanced diet provides adequate vitamin E. However, individuals with certain medical conditions that impair fat absorption are at higher risk of deficiency because vitamin E is a fat-soluble vitamin and requires fat for proper absorption. These conditions include fat malabsorption disorders and some rare genetic diseases such as abetalipoproteinemia and ataxia with vitamin E deficiency.

Symptoms of vitamin E deficiency primarily impact the nervous system and may include muscle weakness, vision problems, numbness, fatigue, and difficulties with movement coordination. In severe cases, the deficiency can even cause blindness.

In areas with food insecurity or among people on very low-fat diets, vitamin E deficiency can arise from insufficient intake. Newborns, especially premature infants, also face a higher risk because the vitamin crosses the placenta minimally during fetal development, leaving newborns with low initial stores. Fortunately, breast milk or formula typically provides adequate vitamin E for infants.

If you notice symptoms such as muscle weakness, vision disturbances, or unusual numbness, it is crucial to consult a healthcare provider to evaluate vitamin E status. Early detection and treatment can prevent the serious consequences associated with this often-missed deficiency.
