Older adults taking daily multivitamins for three years remembered words as if their memory had reversed by over three years — better than the two-year claim. But after 10 years, others showed no benefit at all, even as blood markers improved. The brain didn’t care what the blood said.
There's disagreement
Studies point in different directions — there's no clear consensus yet.
A daily multivitamin might make your brain feel younger — but not everyone agrees.
Some studies found that older adults who took multivitamins for two to three years performed better on memory tests, as if their brains had turned back the clock by two to three years. But other research found no such benefit — even after 16 weeks or more than 10 years of taking them, thinking skills didn’t improve compared to those who took placebos. The positive results came from longer-term studies, while the negative ones include both shorter and very long-term trials, so it’s not clear why they disagree. One thing all studies agree on: multivitamins did improve blood markers, but that didn’t always translate to better brain performance.
If you’re taking a multivitamin for your brain, it might help — but it might not, and we still don’t know why the results are so different.
