Vitamin E. Low Levels Linked to Physical Decline

A study from Yale suggests that older people are susceptible to greater physical decline when Vitamin E blood levels are low.

The researchers measured levels for several nutrients, including folate, vitamins B6, B12, D and E, but only the last vitamin was associated with physical decline for older persons, they report in the Journal of the American Medical Association. 698 people with an average age of 73.7 were followed for three years. Physical performance was measured using the Short Physical Performance

The researchers calculated on two determinants of physical decline: low vitamin E (alpha-tocopherol) levels among people aged between 70 and 80, and being older than 81. Levels of other micronutrients were not associated with declined levels.

Vitamin E plays a major role defending the body from oxidative stress. The researchers suggest three mechanisms which could explain the relationship between low vitamin E levels and the decline in physical function: The increased level of oxidative stress could result in damage to muscle or DNA; there could be an exacerbation of atherosclerosis or other pathologic conditions; and an increase in neurodegenerative disorders.

"Approximately 15 to 30 mg/d of dietary alpha-tocopherol [a component of vitamin E] is needed … this amount can be easily reached through diet, from sources such as almonds, tomato sauce, and sunflower seeds among others or from supplements.
