Daily Multivitamin May Improve Cognition and Protect Against Mental Decline


Various Vitamin Tablets Supplements

Taking a each day vitamin and mineral complement might enhance cognition in older adults, based on new analysis.

Might taking a each day multivitamin complement assist preserve cognitive well being with ageing and probably stop cognitive decline? In line with new analysis, it’d. A brand new research discovered that taking a each day complement might enhance cognition in older adults, however further research are wanted to substantiate these findings earlier than any well being suggestions are made. The research additionally confirmed that each day use of a cocoa extract complement doesn’t profit cognition.

The findings by researchers from Wake Forest College Faculty of Medication, carried out in collaboration with Brigham and Ladies’s Hospital in Boston have been revealed on September 14 in

More than 6.5 million Americans are living with Alzheimer’s disease, according to the Alzheimer’s Association. Furthermore, 1 in 3 seniors die with the disease or another form of dementia.

“There’s an urgent need for safe and affordable interventions to protect cognition against decline in older adults,” said Laura D. Baker, Ph.D., professor of gerontology and geriatric medicine at Wake Forest University School of Medicine and co-principal investigator of the trial, along with Mark Espeland, Ph.D., professor of gerontology and geriatric medicine at Wake Forest University School of Medicine.

The COcoa Supplement and Multivitamin Outcomes Study for the Mind (COSMOS-Mind), was an ancillary study to the COSMOS trial led by Brigham and Women’s Hospital that randomized 21,442 men and women across the U.S. The study investigated whether taking a daily cocoa extract supplement or a daily multivitamin-mineral supplement reduces the risk of developing heart disease, stroke, cancer, and other health outcomes. It was funded by the National Institute on Aging of the National Institutes of Health.

According to Baker, cocoa extract is rich in compounds called flavanols, and past research indicates that these compounds may positively impact cognition. In addition, Baker said that several micronutrients and minerals are needed to support normal body and brain function, and deficiencies in older adults may increase the risk for cognitive decline and dementia.

In COSMOS-Mind, scientists tested whether daily administration of cocoa extract versus placebo and a multivitamin-mineral versus placebo improved cognition in older adults. More than 2,200 participants, ages 65 and older, were enrolled, and they were followed for three years. To evaluate memory and other cognitive abilities, participants completed tests over the telephone at baseline and annually.

“Our study showed that although cocoa extract did not affect cognition, daily multivitamin-mineral supplementation resulted in statistically significant cognitive improvement,” Baker said. “This is the first evidence of cognitive benefit in a large longer-term study of multivitamin supplementation in older adults.”

According to the researchers’ estimations, three years of multivitamin supplementation roughly translated to a 60% slowing of cognitive decline (about 1.8 years). The results showed that benefits were relatively more pronounced in participants with significant cardiovascular disease, which is important because these individuals are already at increased risk for cognitive impairment and decline.

“It’s too early to recommend daily multivitamin supplementation to prevent cognitive decline,” Baker said. “While these preliminary findings are promising, additional research is needed in a larger and more diverse group of people. Also, we still have work to do to better understand why the multivitamin might benefit cognition in older adults.”
