Low blood levels of vitamin E have been linked to greater physical decline in older adults. Researchers looked at several micronutrients, including folate, vitamins B6, B12, D and E, but only vitamin E was associated with physical decline.
The study examined almost 700 people in Tuscany, Italy. Over a period of three years, physical performance was measured using the Short Physical Performance Battery, which included three objective tests of physical function.
The researchers proposed three possible mechanisms which could explain the vitamin E relationship. Vitamin E could prevent the oxidative stress can result in damage to muscle or DNA, diminish atherosclerosis or other pathologic conditions, or prevent neurodegenerative disorders.
