The Claim

In sedentary men aged 50–74, an 8-week daily supplementation with a multivitamin, mineral, and herbal formulation significantly improved contextual recognition memory performance (p < 0.05), with no significant changes observed in other cognitive domains.

Cause and effect
1 study reviewed
In plain English

In sedentary men aged 50–74, daily supplementation with a multivitamin, mineral, and herbal formulation for 8 weeks improved performance on a test of contextual recognition memory, with no change in other memory or cognitive functions.

See the scientific wording

In sedentary men aged 50–74, an 8-week daily supplementation with a multivitamin, mineral, and herbal formulation significantly improved contextual recognition memory performance (p < 0.05), while no significant changes were observed in other cognitive domains, suggesting a selective, short-term benefit for this specific memory process in this population.

Why this might work

Taking a multivitamin with B12 and folate raises levels of these vitamins in the blood, which allows the body to convert a harmful compound called homocysteine into a useful one called methionine. Lower homocysteine reduces damage to blood vessels in the brain and decreases stress on nerve cells. This improves how well nerve cells in memory-related brain areas connect and communicate, leading to better ability to remember where things were seen.

  1. Study: Effects of a multivitamin, mineral and herbal supplement on cognition and blood biomarkers in older men: a randomised, placebo‐controlled trial

    In a study with older men who didn’t exercise much, taking a daily multivitamin for 8 weeks helped them remember where they saw things better, but didn’t help with other memory or thinking tasks. So yes, the supplement made a small, specific improvement.
