The article discusses a study conducted by researchers at Columbia University Irving Medical Center, which found that a daily multivitamin can enhance memory in older adults. The study involved participants aged 55 and older who took either a placebo or a multivitamin for 16 weeks. Those who took the multivitamin exhibited significant improvements in their memory performance compared to the placebo group. The multivitamin used in the study contained high doses of several B vitamins, vitamin C, vitamin D, and vitamin E. The findings suggest that these specific nutrients may play a role in preserving cognitive function in older adults and could potentially be used as a preventive measure against age-related memory decline.
