The Claim
Daily multivitamin-mineral supplementation for 2 to 3 years is associated with a modest but statistically significant improvement in global cognition and episodic memory in adults aged 60 and older, with effect sizes equivalent to reducing cognitive aging by approximately 2 years, based on pooled data from over 5,000 participants across three randomized controlled sub-studies.
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.
Adults aged 60 and older who take a daily multivitamin-mineral supplement for 2 to 3 years show a measurable improvement in overall thinking skills and memory compared to those who do not, with the improvement equivalent to slowing cognitive aging by about two years.

Taking daily vitamins and minerals gives the brain more of the nutrients it needs to make energy and clean up harmful byproducts, which lets brain cells connect better and store memories more effectively.
What the research says
1 studyTaking a daily multivitamin for a couple of years helped older adults think and remember slightly better—like their brains were two years younger. The study tested this directly and found a real, measurable benefit.
