The Claim
Daily multivitamin-mineral supplementation is associated with consistent cognitive benefits across three distinct cognitive assessment methods: clinic-based in-person testing, telephone interviews, and web-based assessments.
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 is linked to similar improvements in cognitive test scores whether the tests are done in a clinic, over the phone, or online.
See the scientific wording
The cognitive benefits of daily multivitamin-mineral supplementation observed in the COSMOS trial are consistent across three different cognitive assessment methods—clinic-based in-person testing, telephone interviews, and web-based assessments—suggesting the effect is robust to measurement mode.
Taking daily vitamins and minerals gives brain cells more of the nutrients they need to make energy and clean up harmful byproducts, which keeps thinking and memory skills steady no matter how the test is given.
What the research says
1 studyTaking a daily multivitamin helped older adults think and remember better, no matter if they took the test in a clinic, on the phone, or online — so the improvement is real and not just because of how the test was given.
