Vitamin E is a fat-soluble antioxidant that plays a key role in protecting the body's cells from harmful oxidative stress and free radicals. Vitamin E helps strengthen the immune system, supports nervous system functionality, and contributes to maintaining healthy skin and tissues. The most biologically active form of vitamin E, alpha-tocopherol, is not only the body's primary vitamin E but also a reliable marker for evaluating total vitamin E levels, upon which this test is based through a blood analysis of s-alpha-tocopherol.
Vitamin E test based on Alpha-Tocopherol
The analysis is based on s-alpha-tocopherol in the blood, the most common and biologically active form of vitamin E. This provides insight into your vitamin E levels and whether they fall within the normal reference range.
Insufficient vitamin E levels can affect the nervous system and muscle function, while excessive levels may negatively impact the blood's ability to clot.
Vitamin E deficiency and symptoms
Vitamin E deficiency is relatively rare but can occur in conjunction with certain conditions or factors that affect fat absorption. Testing for vitamin E may be particularly relevant if:
- You experience symptoms potentially linked to vitamin E deficiency such as muscle weakness, vision problems, nerve damage, or balance issues.
- You have a condition that affects fat absorption such as celiac disease, Crohn's disease, cystic fibrosis, or pancreatitis.
- You are undergoing fat-reducing treatments such as bariatric surgery or taking medications that reduce fat absorption.
- You are curious about your antioxidant status to optimize your health and prevent oxidative stress.
- You take vitamin E supplements and want to ensure your levels are within a safe range.
Understand your vitamin E concentration
Vitamin E is essential for the body's functions and contributes to:
- Cell Protection: Neutralizes free radicals that can damage cells and accelerate aging.
- Immune System: Supports the body's defense against infections and diseases.
- Skin Health: Promotes healthy skin and may reduce inflammation.
- Nerve Function: Helps maintain nerve functionality and protects against nerve damage.
Reference Values for s-alpha-tocopherol
Normal levels of s-alpha-tocopherol range between 12–46 µmol/L. Low levels may indicate a vitamin E deficiency affecting nerve and muscle function, while high levels can suggest overdosage and an increased risk of bleeding.
