The Claim

Daily supplementation with a multivitamin-mineral complex over a 2-year period does not result in a statistically significant improvement in executive function or attention among adults aged 60 years and older.

Source: Effect of multivitamin-mineral supplementation versus placebo on cognitive function: Results from the clinic sub-cohort of the COSMOS randomized clinical trial and meta-analysis of three cognitive studies within COSMOS.

What the research says

1 study

  1. Study: Effect of multivitamin-mineral supplementation versus placebo on cognitive function: Results from the clinic sub-cohort of the COSMOS randomized clinical trial and meta-analysis of three cognitive studies within COSMOS.

    The abstract explicitly reports a non-significant effect on executive function/attention (CI includes zero), indicating no meaningful benefit. This is a key negative finding that refines the scope of MVM’s cognitive benefits.
