The Claim

Daily multivitamin-mineral supplementation in older adults is associated with a reduction in cognitive aging equivalent to approximately two years, based on the effect size observed in global cognition across a meta-analysis of over 5,000 participants.

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.

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 older adults is linked to a slowdown in cognitive aging by about two years, according to a large analysis of studies involving more than 5,000 people.

See the scientific wording

The cognitive benefit of daily multivitamin-mineral supplementation in older adults appears equivalent to reducing cognitive aging by approximately two years, based on the effect size observed in global cognition across a meta-analysis of over 5,000 participants.

Why this might work

Taking daily vitamins and minerals helps brain cells use energy more efficiently and reduces damage from harmful molecules, which lets brain circuits work better and faster, making thinking sharper as if the brain were younger.

    Taking a daily multivitamin for a couple of years helped older adults think a little better—so well that it was like their brains were two years younger than they actually were.
