The Claim
Daily multivitamin supplementation for over a decade has no significant effect on the rate of cognitive decline in men aged 65 years or older, as measured by global cognitive composite scores and verbal memory tests.
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 more than ten years does not change the rate of cognitive decline in men aged 65 or older, based on standardized tests of memory and overall thinking ability.
See the scientific wording
Daily multivitamin supplementation for over a decade has no significant effect on the rate of cognitive decline in men aged 65 years or older, as measured by global cognitive composite scores and verbal memory tests, indicating that such supplementation does not prevent age-related cognitive deterioration in this well-nourished, highly educated male population.
The brain's nerve cells already get all the vitamins they need from a normal diet, so adding extra vitamins doesn't change how they stay healthy, connect to each other, or handle aging stress over time.
What the research says
1 studyStudy: Long-Term Multivitamin Supplementation and Cognitive Function in Men
This study gave older men either a daily vitamin or a fake pill for over 10 years and found their memory and thinking skills got worse at the same rate no matter which one they took. So, the vitamins didn’t help slow down brain aging.
