The Claim

Daily multivitamin-mineral supplementation significantly improves global cognition and episodic memory in community-dwelling older adults, as demonstrated by a meta-analysis of three COSMOS cognition subcohorts.

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.

Cause and effect
1 study reviewed
In plain English

Taking a daily multivitamin-mineral supplement is associated with better overall thinking skills and memory in older adults living in the community.

See the scientific wording

A meta-analysis of three COSMOS cognition subcohorts (COSMOS-Clinic, COSMOS-Mind, COSMOS-Web) demonstrates significant benefits of daily multivitamin-mineral supplementation on global cognition and episodic memory in community-dwelling older adults, suggesting a consistent effect across different cognitive assessment methods.

Why this might work

Taking daily vitamins and minerals gives brain cells the nutrients they need to make energy more efficiently and clean up harmful waste products, which helps memory circuits work better.

What the research says

1 study
  1. Study: Effect of multivitamin‐mineral supplementation on change in cognitive function in the COSMOS Clinical subcohort and meta‐analysis of COSMOS cognition studies

    Taking a daily multivitamin was linked to a tiny but real improvement in memory for older adults, and this was seen across three different studies using different ways to test thinking skills.
