Taking a daily multivitamin may help slow age-related memory decline, a study has found.
Over 3,500 adults aged 60 and above participated in the study, taking either a daily multivitamin or a placebo for three years. The results showed that those on multivitamins experienced memory improvement equivalent to about three years of age-related memory decline.
Taking a daily multivitamin supplement can slow age-related memory decline, finds a large study led by researchers at Columbia University and Brigham and Women’s Hospital/Harvard.
“Cognitive aging is a top health concern for older adults, and this study suggests that there may be a simple, inexpensive way to help older adults slow down memory decline,” says study leader Adam M. Brickman, PhD, professor of neuropsychology at
Study methods
In the current study, more than 3,500 adults (mostly non-Hispanic white) over age 60 were randomly assigned to take a daily multivitamin supplement or placebo for three years. At the end of each year, participants performed a series of online cognitive assessments at home designed to test memory function of the hippocampus, an area of the brain that is affected by normal aging. The COSMOS-Web study is part of a large clinical trial led by Brigham & Women’s Hospital and Harvard called the COcoa Supplement and Multivitamin Outcomes Study (COSMOS).
By the end of the first year, memory improved for people taking a daily multivitamin, compared with those taking a placebo. The researchers estimate the improvement, which was sustained over the three-year study period, was equivalent to about three years of age-related memory decline. The effect was more pronounced in participants with underlying
Good nutrition important for aging brain
Though the researchers did not look at whether any specific component of the multivitamin supplement was linked to the improvement in memory, the findings support growing evidence that nutrition is important for optimizing brain health as we age.
“Our study shows that the aging brain may be more sensitive to nutrition than we realized, though it may not be so important to find out which specific nutrient helps slow age-related cognitive decline,” says Lok-Kin Yeung, PhD, a postdoctoral researcher in Columbia’s Taub Institute for Research on
