The Claim
Among adults aged 65 and older who later developed mild cognitive impairment, daily multivitamin-mineral supplementation was associated with a 0.26 standard deviation slower rate of cognitive decline in the year before diagnosis compared to placebo, with greater effects observed in global cognition and executive function.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults aged 65 and older who later developed mild cognitive impairment, those who took a daily multivitamin-mineral supplement experienced a slower rate of cognitive decline in the year before diagnosis compared to those who took a placebo, particularly in overall thinking skills and executive function.
See the scientific wording
Among adults aged 65 and older who later developed mild cognitive impairment, those previously assigned to daily multivitamin-mineral supplementation showed a 0.26 standard deviation slower rate of cognitive decline in the year before diagnosis compared to those on placebo, particularly in global cognition and executive function.
Daily multivitamin-mineral supplements provide essential nutrients that help brain cells produce energy more efficiently and reduce damage from harmful molecules, which slows down the loss of thinking skills as the brain begins to show early signs of decline.
What the research says
1 studyOlder adults who took a daily multivitamin and later developed memory problems still lost their thinking skills more slowly than those who took a sugar pill. The multivitamin didn’t stop memory problems from happening, but it helped slow them down once they started.
