Can multivitamins improve memory? A new study shows 'intriguing' results
They tracked about 3,500 older adults who were enrolled in a randomized controlled trial.
One group of participants took a placebo, and another group took a Silver Centrum multivitamin, for 3 years.
At the end of the first year, people taking a multivitamin showed improvements in the ability to recall words.
People taking the multivitamin were able to recall about a quarter more words, which translates into remembering just a few more words, compared to the placebo group.
"We estimate that the effect of the multivitamin intervention improved memory performance above placebo by the equivalent of 3.1 years of age-related memory change," the authors write in their paper, which was published this week in the American Journal of Clinical Nutrition.
And the authors point to a sustained benefit.
