A third major study has found evidence that daily multivitamin supplements improve memory and slow cognitive aging in older adults. The research, conducted by Mass General Brigham, tested the effects of a daily multivitamin on cognitive changes in a study of 573 participants in the COSMOS trial.
The results showed a statistically significant benefit for cognition among participants taking the multivitamin compared to placebo. This suggests that a multivitamin could help prevent memory loss and slow cognitive aging among older adults.
The study focused on participants who underwent in-person assessments, along with the results of a combined analysis from three separate studies. The results from this latest report confirm consistent and statistically significant benefits of a daily multivitamin versus a placebo for both memory and global cognition.
