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.
Important! The analysis can only be performed at clinics affiliated with SYNLAB or Karolinska. When analyzing s-alpha-tocopherol, retinol (vitamin A) is also reported, which means that you will also receive an answer to your vitamin A level.
