Vitamin E Alpha, or alpha-tocopherol, is a fat-soluble antioxidant that plays a crucial role in protecting cell membranes from oxidative damage. It is primarily obtained through dietary sources such as nuts, seeds, and vegetable oils.

The measurement of Vitamin E Alpha in the blood is used to evaluate nutritional status, particularly in cases of suspected deficiency or toxicity. It is also important in the diagnosis and management of malabsorption disorders.

Normal levels of Vitamin E Alpha range from 12 to 42 μmol/L. Levels below this range may indicate a deficiency, while levels above may suggest excessive supplementation or underlying health conditions.
