Vitamin E is a fat-soluble vitamin that acts as an antioxidant and free-radical scavenger in lipophilic environments. Vitamin E requires bile for absorption, and 25% of it is absorbed orally. The vitamin is stored in adipose tissue, liver, and muscle.
The reference range of vitamin E in adults is 5.5-17 µg/mL. In children, it is 3-18.4 µg/mL.
