Rating (out of 5): 2

Vitamin E, particularly in the form of natural tocopherols, is often marketed as an antioxidant that may help prevent or slow aging by protecting cells from oxidative damage. Scientific validation for its use in aging prevention is limited. Several epidemiological and observational studies have suggested that higher dietary intake of Vitamin E is associated with a reduced risk of age-related diseases, such as cardiovascular diseases and some neurodegenerative conditions. However, large randomized controlled trials (RCTs) have generally failed to show significant benefits of Vitamin E supplementation in extending lifespan or preventing age-related decline in otherwise healthy adults.

Some studies indicate that Vitamin E may play a role in skin health, helping to reduce signs of photoaging when applied topically, but oral supplementation results are inconsistent. The antioxidant properties of Vitamin E are biologically plausible in combating oxidative stress linked to aging, but direct evidence for its effectiveness in aging prevention or longevity is weak. Furthermore, high-dose supplementation may carry risks, including increased mortality in certain populations as shown in some meta-analyses.

In summary, while Vitamin E’s role as an antioxidant provides a scientific rationale for its use in aging prevention, robust clinical evidence supporting its effectiveness in this context is lacking. Current guidelines suggest that obtaining Vitamin E from dietary sources is preferable to supplementation for the general population.
