What is Vitamin E?
Vitamin E is a fat-soluble antioxidant that exists in eight different forms. Alpha-tocopherol is the most biologically active form and the one preferentially used by the human body.
Membrane Protection
Vitamin E's primary function is protecting cell membranes from oxidative damage caused by free radicals. It's particularly important for cells exposed to high oxygen levels, like those in the lungs and eyes.
Skin Health
Applied topically or consumed orally, vitamin E supports skin health by protecting against UV damage, promoting wound healing, and maintaining the skin's moisture barrier.
Food Sources
The best sources include wheat germ oil, sunflower seeds, almonds, hazelnuts, spinach, and avocados. Most people can meet their needs through a varied diet rich in nuts and seeds.
Supplementation Considerations
Natural vitamin E (d-alpha-tocopherol) is more bioavailable than synthetic forms (dl-alpha-tocopherol). High-dose supplementation should be approached with caution, as some studies have suggested potential risks at very high levels.
