The Claim
Daily supplementation with a multivitamin-mineral for three years has no significant effect on the incidence of mild cognitive impairment or dementia in adults aged 65 and older, although it is associated with a modest slowing of cognitive decline in individuals who subsequently develop mild cognitive impairment.
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-mineral supplement for three years does not lower the chance of developing mild cognitive impairment or dementia in adults aged 65 and older, but it is linked to a small reduction in the rate of cognitive decline among those who later develop mild cognitive impairment.
See the scientific wording
Daily supplementation with a multivitamin-mineral for three years does not significantly reduce the incidence of mild cognitive impairment or dementia in adults aged 65 and older, despite showing a modest slowing of cognitive decline in those who later developed mild cognitive impairment.
Taking daily multivitamins and minerals keeps brain cells working more efficiently by supporting energy production and reducing minor chemical imbalances, but it does not stop the underlying damage that leads to memory loss or dementia.
What the research says
1 studyTaking a daily multivitamin for three years didn’t stop older adults from developing memory problems, but for those who still got memory issues, their thinking skills declined a little slower than those who didn’t take the vitamin.
