Vitamin E is a fat-soluble vitamin that is crucial in maintaining overall health. It exists in eight different forms, but alpha-tocopherol is the most active and abundant form in the human body. One of its primary functions is to act as an antioxidant, protecting cells from damage caused by free radicals, which are unstable molecules that can contribute to various diseases.
Beyond its antioxidant properties, vitamin E is involved in several other important bodily functions. It supports the immune system, helping the body fight off infections and diseases. It also plays a role in cell signaling and gene expression, influencing various processes such as cell growth and differentiation. Additionally, vitamin E is essential for blood clotting and vascular health.
Vitamin E is naturally found in a variety of foods, including vegetable oils, nuts, seeds, and leafy green vegetables. While deficiencies are rare in healthy individuals, certain groups, such as those with fat malabsorption disorders or premature infants, may be at risk. The recommended daily intake of vitamin E for adults varies depending on age and gender, but it typically falls within the range of 3 to 15 mg per day. Consult the UK National Health Service (NHS) website for specific recommendations and further information on vitamin E.
