Vitamin E is a fat-soluble vitamin that plays a crucial role in maintaining overall health and well-being. It is an essential nutrient that primarily functions as an antioxidant, helping to protect cells from damage caused by free radicals. While vitamin E is important for various bodily functions, the recommended daily allowance for vitamin E is typically measured in international units (IU), not milligrams (mg). The recommended dietary allowance (RDA) for vitamin E varies depending on factors like age, gender, and life stage.
