Vitamin E (mixed tocopherols) is an antioxidant that has been investigated for its potential role in the prevention of aging and age-related conditions. The rationale is that oxidative stress, driven by reactive oxygen species (ROS), contributes to cellular damage and the aging process. Vitamin E, being a lipid-soluble antioxidant, can protect cell membranes from oxidative damage. However, while laboratory and animal studies suggest antioxidant supplementation can reduce markers of oxidative stress, the translation of these findings to human aging is limited.

Large-scale, long-term randomized controlled trials in humans have not consistently demonstrated that Vitamin E supplementation slows the aging process, prevents age-related diseases, or extends lifespan. Some observational studies suggest diets rich in Vitamin E may be associated with healthier aging outcomes, but these findings are confounded by other healthy lifestyle factors. Moreover, high-dose Vitamin E supplementation has not been shown to offer substantial benefit and, in some studies, has been associated with increased risks (e.g., hemorrhagic stroke).

In summary, while the use of Vitamin E for aging prevention is grounded in plausible biological mechanisms and some historical enthusiasm, robust scientific evidence supporting its efficacy in preventing aging or age-related decline in humans is weak. Current guidelines do not recommend Vitamin E supplementation specifically for aging prevention in healthy adults.
