A large-scale study conducted by researchers at Columbia University and Brigham and Women’s Hospital/Harvard has found that taking a daily multivitamin supplement can slow down age-related memory decline in older adults. Over 3,500 adults aged 60+ were assigned a multivitamin or placebo for three years. After the first year, memory improved in the multivitamin group, with the effect sustained throughout the study. The improvement was more significant in participants with underlying cardiovascular disease. The findings suggest that multivitamin supplementation could be a safe and affordable method for protecting cognitive health in older adults. However, consulting a physician is advised.
