To investigate, researchers studied more than 10,000 men over the age of 65 between 1985 and 1993.
Researchers found that vitamin E had no effect on mortality in men aged 65-70, but it reduced mortality by 24 percent among participants age 71 or older.
The protective effect was most prominent for men over the age of 71, who had a high vitamin C intake and smoked less than a pack of cigarettes per day.
Among 2,284 men with dietary vitamin C intake above the median who smoked less than a pack of cigarettes per day, vitamin E extended their lifespan by up to two years.
In the other participants, consisting of 80% of the cohort, vitamin E did not affect mortality.
Researchers propose that it might be useful to analyze the effect of vitamin E supplementation in large controlled trials by the age of the participant at the follow-up and not just by the time after randomization that has been customary.
The study has been published in the journal Age and Ageing.
