The Claim

Multivitamin supplementation reduces cognitive aging by approximately two years in older adults, whereas creatine supplementation at 5g/day for six weeks does not improve cognitive performance in healthy young adults.

What the research says

Supports is higher

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

In plain English

Taking multivitamins slows cognitive decline in older adults by about two years. Creatine supplements do not improve cognitive performance in healthy young adults.

See the scientific wording

Multivitamin supplementation reduces cognitive aging by approximately two years in older adults, whereas creatine supplementation at 5g/day for six weeks does not improve cognitive performance in healthy young adults.

Why this might work

Vitamins and minerals from a multivitamin help brain cells make energy and protect them from damage, which keeps the brain working better as people get older.

What the research says

4 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.

    This study found that taking a daily multivitamin helped older adults' brains work a bit better, equivalent to being 2 years younger, which matches the first part of the claim. It didn't test creatine, so it can't say anything about that part.

  2. Study: Multivitamin supplementation improves memory in older adults: a randomized clinical trial.

    The study shows that taking a daily multivitamin helps older adults remember better, making their memory about 3 years younger, which matches the claim that multivitamins slow cognitive aging by about two years.
