The Claim
In healthy adults aged 55–65, 16 weeks of daily multivitamin supplementation has no causal effect on performance in computerized cognitive tasks assessing spatial working memory, contextual memory, or executive function, despite observed biomarker improvements.
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.
Taking a daily multivitamin for 16 weeks does not improve performance on tests of memory and thinking skills in healthy adults aged 55 to 65, even though some biological markers changed.
See the scientific wording
In healthy adults aged 55–65, 16 weeks of daily multivitamin supplementation does not improve performance on computerized cognitive tasks assessing spatial working memory, contextual memory, or executive function, indicating no causal effect on cognition despite biomarker improvements.
Taking daily multivitamins lowers harmful substances in the blood like homocysteine, oxidative damage markers, and inflammation signals, but these changes do not reach the brain in a way that improves how nerve cells communicate or store memories.
What the research says
1 studyPeople over 55 took a daily multivitamin for 16 weeks, and while their blood tests got better, their memory and focus tests didn’t improve at all. So the vitamin didn’t help their brain performance.
