The Claim
Multivitamin supplementation in older adults is associated with an improvement in immediate verbal memory equivalent to reversing 3.1 years of age-related memory decline, as estimated by cross-sectional modeling of age and ModRey performance.
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 older adults, taking a multivitamin is linked to a level of improvement in immediate verbal memory that matches the amount of memory loss typically seen over 3.1 years of aging, according to statistical modeling of age and memory test scores.
See the scientific wording
The cognitive benefit of multivitamin supplementation on immediate verbal memory in older adults is equivalent to reversing 3.1 years of age-related memory decline, based on cross-sectional modeling of the relationship between age and ModRey performance, suggesting a clinically meaningful effect despite its small absolute magnitude.
Taking a daily multivitamin increases key vitamins in the blood, which activate receptors in the memory center of the brain. This boosts the growth of new nerve cells and strengthens connections between them, allowing the brain to better hold onto new verbal information right after hearing it.
What the research says
1 studyStudy: Multivitamin supplementation improves memory in older adults: a randomized clinical trial.
Taking a daily multivitamin for three years helped older adults remember slightly more words on a memory test, and that improvement was about the same as the memory boost you’d get by being 3.1 years younger.
