Vitamin E Toxicity

Excerpt

Vitamin E is a major lipid-soluble antioxidant obtained exclusively from the diet. It was discovered in the 1920s as an essential dietary element required by rats for reproduction. There are approximately eight different vitamin E-related molecules, but the dominant molecule in humans is alpha-tocopherol. Tocotrienols are the other molecules that are widely studied for vitamin E supplementation. These two molecules have been studied in various dosages and for many different health purposes. Vitamin E has peroxyl radical scavenger properties. While vitamin E toxicity is associated with an increased risk of bleeding, its deficiency has been associated with neurologic diseases and anemia.
