The Claim

Daily multivitamin-mineral supplementation for two to three years improves episodic memory and global cognition in adults aged 60 and older, with effect sizes equivalent to reversing 2 to 4.8 years of cognitive aging.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

In plain English

Taking a daily multivitamin and mineral supplement for two to three years leads to better episodic memory and overall cognitive performance in adults aged 60 and older, with the improvement matching the cognitive gain of aging backward by 2 to 4.8 years.

Daily multivitamin-mineral supplementation for two to three years improves episodic memory and global cognition in adults aged 60 and older, with effect sizes equivalent to reversing 2 to 4.8 years of cognitive aging.

Why this might work

Daily multivitamins provide key nutrients that lower harmful oxidative damage in brain cells, boost energy production in mitochondria, and strengthen the connections between neurons involved in forming and recalling memories.

What the research says

3 studies

  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.

    Taking a daily multivitamin for two years slightly improved memory and thinking skills in older adults, as if their brains were 2 years younger. This doesn't mean it fixes all memory problems, but it does help a little.

  2. 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 for two years helped older adults remember things a little better, like names or stories, according to a big study. It didn't clearly help with all thinking skills, but memory improved enough to be real.
