Nutrient Category: | Vitamins and Other Components | ||
Measuring Unit: | mg | ||
Nutrient Summary: | Vitamin E acts as an antioxidant, it helps to protect cells from the damage caused by free radicals. It boosts body's immune system to fight off invading bacteria and viruses. | ||
Nutrient Function: |
Vitamin E's main action is to stop the chain reaction of free radicals from producing more free radicals in body cells. As a result, it has the following functions:
Notes: 1) There are 8 naturally occurring forms of vitamin E. Only the alpha-tocopherol form of the vitamin E is maintained in the plasma and meet the body’s needs for the vitamin. 2) Alpha-tocopherol has forms 2R-stereoisomeric and 2S-stereoisomers. Only 2R-stereoisomeric form is maintained in the plasma and tissues, so it is used for the recommended daily intake value. Vitamin E supplement labeled as dl-alpha-tocopherol includes both forms of alpha-tocopherol vitamin E. 3) Prolonged and high-intensity physical activity can increase muscles oxygen consumption significantly, as a result, the production of free radicals in the body increases. So active people can be benefited to eat more Vitamin E and other antioxidant-rich fruits and vegetables regularly. 4) Vitamin E is a fat-soluble nutrient, it is more easily absorbed in a meal that contains fat. Fat-soluble vitamins are held in fatty tissues and the liver, and released as needed. |

Deficiency Health Effects |
Vitamin E deficiency is very rare in the United States and Canada. However, most people intake less than recommended daily amounts of vitamin E from diets. Vitamin E deficiency only occurs for the individuals with genetic abnormalities of vitamin E metabolism, or fat digest or malabsorption problems. The primary symptom of vitamin E deficiency is peripheral neuropathy (neuromuscular dysfunction), which may lead to loss of feeling in the arms and legs, loss of body movement control, muscle weakness, and vision problems. Another problem is the weakened immune system. |
Effects if Above Upper Limit |
Currently, there is no evidence of adverse effects from the excess consumption of vitamin E naturally occurring in foods. Though Vitamin E toxicity is rare, if it happens, the potential adverse effects of excessive vitamin E supplements intake are increasing the risk of bleeding, and causing hemorrhage. For the individuals who are deficient in vitamin K or on anticoagulant therapy, it may diminish blood coagulation. The Upper Limit for vitamin E is based on the adverse effect of increased tendency to hemorrhage. The UL for adults is 1,000 mg/day from all forms of alpha-tocopherol. |
