A daily multivitamin is linked to better health in older adults in a new study


Taking a daily multivitamin could enhance mind perform in older adults, and a new study suggests the advantages are better for these with heart problems.

The findings did not shock the researchers, however fairly stunned them, stated study creator Laura Baker, a professor of gerontology and geriatric medication at Wake Forest University in North Carolina.

“I’ve to use the phrase ‘shocked,'” Baker stated.

Researchers at Wake Forest University School of Medicine, in collaboration with Brigham and Women’s Hospital in Boston, analyzed cognitive perform in older adults assigned to take flavonoid-containing cocoa extract dietary supplements, multivitamins, or placebos each three days. a yr. Until the outcomes had been revealed, nobody, not even the researchers, knew who was assigned to which agenda.

“We actually believed that cocoa extract may need some cognitive profit primarily based on preliminary reviews of cardiovascular advantages. So we’re ready for that massive discovery in the information evaluation – and it isn’t cocoa extract, however fairly a multivitamin that has benefited us,” stated Baker. “We’re excited as a result of our findings open up a new avenue of analysis – easy, reasonably priced, secure. , for a low-cost intervention, it might present a layer of safety in opposition to cognitive decline.”

But he added that he and his group aren’t prepared to suggest that older adults instantly add a daily multivitamin primarily based on these outcomes.

The findings, revealed Wednesday in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, are imprecise and can’t be generalized to the general public. More analysis is wanted to affirm them.

“It’s too early to make any suggestions,” Baker stated. “I feel we should always do this in one other study.”

The new study included 2,262 individuals aged 65 and older who had been enrolled for 3 years between August 2016 and August 2017. Participants accomplished annual phone checks to assess cognitive perform. They scored on story recall, verbal fluency, and quantity ordering, amongst different checks.

Researchers in contrast daily cocoa extract with placebo and analyzed perform primarily based on check scores amongst these taking a daily multivitamin in contrast with placebo.

Researchers discovered that taking multivitamins for 3 years slowed cognitive getting older by 1.8 years, or 60%, in contrast to a placebo. Daily cocoa extract supplementation for 3 years didn’t have an effect on cognitive perform, the researchers wrote.

The study — supported by the National Institutes of Health’s National Institute on Aging — additionally discovered that multivitamins had been most helpful for older adults with heart problems.

“It is recognized that individuals with danger components for heart problems could have decrease ranges of nutritional vitamins and minerals in their blood. “So supplementing with these nutritional vitamins and minerals can enhance cardiovascular health and, in flip, cognitive health — and we all know there’s a sturdy connection between cardiovascular health and mind health,” stated Dr. Kate Vossel, professor of neurology and the Mary S. Director of the Easton Center, Los Angeles.

Because of the hyperlink between cardiovascular and mind health, taking steps to forestall heart problems or different persistent illnesses — reminiscent of consuming a nutritious diet and exercising — can also profit the mind, stated Vossel, who was not concerned in the new study.

“If we are able to actually remove or actually forestall persistent illnesses, we are able to forestall dementia,” he stated. “Approximately 40% of dementia is preventable with better preventative measures over the course of a lifetime.”

The particular components driving this hyperlink between multivitamins and cognitive perform are unclear and require extra analysis, however Baker and his group suppose the findings might assist individuals who lack micronutrients like vitamin C and vitamin E profit from multivitamins. , magnesium or zinc.

“The situation can worsen with age. Many of our seniors usually are not getting sufficient diet for a variety of causes,” Baker stated.

“As we get older, we’ve got extra medical circumstances that may make micronutrient deficiencies worse,” he stated. “The drugs we take for these circumstances can even contribute to micronutrient deficiencies by interfering with the physique’s capability to soak up these important vitamins from the weight loss program.”

Other research have had combined outcomes on the hyperlink between sure nutritional vitamins and dietary supplements and dementia danger, Vossel cautioned.

“We’ve been down this highway a whereas again with analysis on nutritional vitamins and dementia. For years, dementia specialists have been recommending vitamin E primarily based on early promising outcomes for vitamin E and cognition, notably in Alzheimer’s illness sufferers. But since then, the outcomes have been totally different,” stated Vossel.

He added that seniors ought to speak to their major care doctor earlier than beginning a vitamin or complement routine.

“Supplementation is normally secure, nevertheless it needs to be fastidiously monitored, particularly in individuals with reminiscence loss, as a result of taking too many nutritional vitamins might be harmful,” Vossel stated. “Vitamin E overdose or taking excessive ranges of vitamin E additionally will increase the chance of bleeding. So these are just a few ideas.”

Overall, the new study’s findings are encouraging, stated Heather Snyder, Alzheimer’s Association vice chairman of medical and scientific communications.

“Obviously there’s additional work we want to see – particularly unbiased validation in research in bigger and extra various populations – however this is encouraging,” he stated. “More analysis is wanted to perceive the advantages of multivitamins.”
