Indication: Cognitive function
Source: Am J Clin Nutr, 2003;77:975-984.
Research: Researchers tested the cognitive function of almost 15,000 women, aged 70 to 79 participating in the Nurses’ Health Study. The tests included memory, immediate and delayed recall of lists of words and tests of verbal fluency. For example, one of the tests asked women to name as many animals as they could in one minute. (The responses ranged from two to 38 animal names.) Test scores were compared with the subjects’ use of vitamin E and C supplements.
Results: Women who had been taking both vitamin E and C supplements for at least 10 years had significantly better cognitive performance than women who had never taken those supplements. The benefits were less consistent among women who had taken vitamin E alone, and no benefits were associated with vitamin C alone. The analyses also showed a trend of increased benefit with duration of supplement use and was stronger among women with poor dietary intake of vitamin E.
