Adults over age 60 who want to stave off memory loss could benefit from taking a daily multivitamin supplement, suggests a recent study from Columbia University in New York and Brigham and Women’s Hospital/Harvard in Boston.”Daily multivitamin supplementation improved memory in older adults after one year, an effect that was sustained, on average, over the three years of follow up,” Adam M. Brickman, PhD, professor of neuropsychology at Columbia University Vagelos College of Physicians and Surgeons, told Fox News Digital.During the study — published in The American Journal of Clinical Nutrition — more than 3,500 adults over age 60 were randomly assigned to take either a daily multivitamin or a placebo for a three-year period. ROSALYNN CARTER DIAGNOSED WITH DEMENTIA AT 95: WHAT TO KNOW ABOUT THE CONDITION IN THE ‘OLDEST OLD’At the end of each year, the participants completed self-administered cognitive tests to determine the strength of their memory.After the first year, those taking the multivitamin showed memory improvement compared to the placebo group — an effect that continued over the entire course of the study. Adults over age 60 who want to stave off memory loss could benefit from taking a daily multivitamin supplement, suggests a recent study.

(He was not involved in the study.)”Improvements were seen in specific areas of memory like immediate recall, but not in executive function (decision-making) or object recognition in the multivitamin group compared with placebo,” Deland told Fox News Digital. “There are risk factors that we don’t know about yet, and I believe nutrition is a significant one.” There was also a sampling bias, with the bulk of the patients in the study falling into a certain demographic, as lead researcher Brickman pointed out.”The study participants were predominantly White with high education, and therefore not representative of the U.S. population,” he told Fox News Digital. “The demographic composition of the participants limits our ability to generalize the findings.” “Daily multivitamin supplementation improved memory in older adults after one year, an effect that was sustained, on average, over the three years of follow up,” the study author told Fox News Digital.

While it often occurs after a stroke, it can also result from other conditions that interrupt the flow of oxygen and nutrients to the brain.Multivitamins not always essential, but can be beneficialWhile it may seem that multivitamins are beneficial to everyone, “the common thinking in the past has been that they don’t benefit older adults, especially in the setting of a healthy, balanced diet,” according to Hackensack’s Deland. Some large review studies suggest that B vitamins, vitamin C, calcium, magnesium and zinc are most relevant to cognitive performance, a doctor told Fox News Digital. (iStock)”However, the increasing prevalence of Alzheimer’s disease in the U.S. suggests that there are risk factors we don’t know about yet, and I believe nutrition is a significant one,” he went on. Given that numerous studies have suggested that diets low in nutrient density or high in highly processed ingredients can increase the chances of someone developing cognitive impairment, Deland believes that supplementing the diet with multivitamins may help preserve cognitive function. “This is especially important in the care of our elderly population, for whom access to fresh, nutritious food is limited by availability, accessibility and cost,” Deland said. AI TOOL GIVES DOCTORS PERSONALIZED ALZHEIMER’S TREATMENT PLANS FOR DEMENTIA PATIENTS”I’ve found that it’s easier to get patient buy-in through suggesting vitamin supplementation rather than just saying, ‘Eat better’ — not to mention that it’s simpler to take one multivitamin than numerous individual vitamin supplements,” he added.As far as specific vitamins and minerals that actually deliver the memory boost, Deland noted that large review studies suggest that B vitamins, vitamin C, calcium, magnesium and zinc are most relevant to cognitive performance — and that a deficiency in them is relatively common. Older adults who are considering taking a daily multivitamin should talk to their physicians about whether that supplementation is appropriate for them, the lead author of a new study noted. (iStock)”And while they are not technically vitamins, the compounds resveratrol (found in grapes, berries and red wine), quercetin (found in unprocessed fruits and vegetables) and curcumin may all have benefit in preserving cognition into later life,” he added.Vitamin D deficiency is linked to worse cognition in later life, Deland said, while omega-3 fatty acid intake has been shown to aid in memory and cognitive function.Doctor input is keyOlder adults who are considering taking a daily multivitamin should talk to their physicians about whether supplementation is appropriate for them, Brickman noted.This study was geared toward cognitive or memory changes that occur with normal aging, the researcher pointed out.IN ALZHEIMER’S STUDY, SLEEPING PILLS ARE SHOWN TO REDUCE SIGNS OF DISEASE IN THE BRAIN”Our data do not suggest a treatment or preventative strategy for diseases that affect memory, like Alzheimer’s disease,” he clarified. “If older adults are concerned about their memory, they should seek an evaluation by a memory specialist and/or speak to their doctors about their concerns.”Particularly for adults who are already taking other supplements, it’s important to check with a doctor before adding a multivitamin to the mix, Raziano noted.Too many vitamins could cause “toxicity and a potential overdose.” “There’s always the risk of polypharmacy,” she warned. “We don’t want [people] taking too much of anything, which could lead to vitamin toxicity and a potential overdose.”Deland agreed with this. “Always discuss supplementation and dietary changes with your doctor,” he said. “While there is a potential benefit to multivitamin supplementation, other supplements may have important interactions with medications or medical conditions.”CLICK HERE TO SIGN UP FOR OUR HEALTH NEWSLETTEROne benefit of multivitamins, however, is that the contents of the pills are pretty tightly controlled, Raziano pointed out.She recommends going with a high-quality Centrum brand-name multivitamin; check to make sure it’s a fresh, non-expired bottle.CLICK HERE TO GET THE FOX NEWS APPIn addition to potentially taking multivitamins, Deland stressed the importance of prioritizing fresh, unprocessed foods and getting frequent aerobic exercise totaling at least 150 minutes weekly, “to preserve your independence and your mind.” Melissa Rudy is health editor and a member of the lifestyle team at Fox News Digital.
