The Claim
Multivitamin supplementation in older adults is associated with cognitive performance equivalent to two years less cognitive aging than no supplementation.
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.
Older adults who take multivitamins show cognitive test scores similar to those of people two years younger who do not take multivitamins.
See the scientific wording
Multivitamin supplementation in older adults is associated with cognitive benefits equivalent to two years less cognitive aging.
Taking daily multivitamins raises levels of key vitamins in the blood, which activate receptors in the memory center of the brain. This triggers new nerve cell growth and strengthens connections between brain cells, leading to better recall of recent events.
What the research says
4 studiesOlder adults who took a daily multivitamin for two years performed on cognitive tests as if they were two years younger than those who didn’t take the vitamin. The study found this difference was real and not due to chance.
Study: Multivitamin supplementation improves memory in older adults: a randomized clinical trial.
Older adults who took a daily multivitamin for three years remembered words better, as if their memory had gotten younger by over three years—better than the two-year improvement claimed. So yes, the study backs up the idea that multivitamins help memory in older people.
