The Claim
Daily multivitamin-mineral supplementation in older adults is associated with a magnitude of improvement in global cognition equivalent to a reduction of two years of cognitive aging, as observed in the COSMOS meta-analysis.
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 might make your brain act as if it’s two years younger, based on a big study of older adults.
See the scientific wording
The cognitive benefit of daily multivitamin-mineral supplementation in older adults was equivalent to reducing cognitive aging by two years, based on the magnitude of improvement in global cognition observed in the COSMOS meta-analysis.
Daily vitamins and minerals help brain cells use energy better and reduce damage from harmful molecules, which lets brain circuits work more efficiently and improves memory and thinking skills.
What the research says
1 studyTaking a daily multivitamin for two years helped older adults’ brains perform a little better on memory and thinking tests—so well, in fact, that the researchers said it was like their brains acted two years younger.
