This is promising news.
A trio of studies, involving over 5,000 participants, suggests that the daily intake of a multivitamin may serve as a protective measure against memory loss in older adults. Dr. Chirag Vyas, an instructor in investigation at Massachusetts General Hospital, stated that the collective findings indicated that, in comparison to a placebo, a daily multivitamin could potentially slow cognitive aging by around two years. These studies were conducted as part of the COSMOS trial, a larger clinical investigation exploring whether a daily multivitamin (specifically, Centrum Silver), a cocoa extract supplement, or a combination of both could offer protection against heart disease and cancer. The latest study, published in The American Journal of Clinical Nutrition, involved 573 adults aged 60 and above, who took either a multivitamin or a placebo daily for a period of two years.
Dr. Vyas and his research team concluded that a daily multivitamin had a modest impact on mitigating normal age-related memory loss, benefiting both overall cognition and the ability to recall day-to-day memories. However, there remains uncertainty regarding the specific vitamins and minerals responsible for this protective effect and the mechanisms through which they exert their influence. Dr. Vyas emphasized the necessity for future studies to pinpoint the micronutrients contributing to cognitive benefits and advocated for greater diversity among research participants.
With advancing age, the membranes surrounding brain cells tend to deteriorate, and vitamins may play a role in safeguarding against this decline. Despite the plausible notion that vitamins alone could preserve cognitive function, Dr. Richard Caselli, a neurology professor emeritus at the Mayo Clinic, expressed some reservations based on the relatively brief duration of the studies. He acknowledged the minimal cognitive change observed over three years in healthy individuals without Alzheimer’s.
Dr. Zaldy Tan, a geriatric medicine physician at the Cedars Sinai Jona Goldrich Center for Alzheimer’s and Memory Disorders, suggested that individuals deficient in specific vitamins might experience greater benefits from a multivitamin. He highlighted the potential link between deficiencies in vitamins such as B12, A, and E and cognitive health. However, the evidence in this regard remains inconclusive, and the universal benefit of supplementation for the general public is not assured.
In addressing cognitive decline, Caselli underscored the importance of maintaining overall health. He recommended staying socially, mentally, and physically active and addressing common health conditions like heart disease, sleep apnea, and diabetes. While acknowledging the likely benefits of a daily multivitamin supplement, Caselli emphasized the critical role of a healthy diet and lifestyle in promoting optimal brain health.
