Multivitamins may help prevent memory impairment in older people



Studies conclude that a daily multivitamin intake is sufficient to prevent memory loss in older adults.

The brain needs several nutrients for optimal health. New research reveals multivitamin Daily use may slow the age-related decline in memory in older people.

This was a three-year study of 3,500 participants aged 60 and older, and the findings are published in a journal. American Journal of Clinical Nutritionthe authors say the results are “remarkable” but that more research is needed.

The scientists did not analyze whether specific ingredients in the supplement were associated with better memory, but “the conclusion is that nutrition is important for optimizing brain health as we age.” They say it supports growing evidence that

The responsible scientists are from Brigham and Women’s Hospital in the United States and Columbia University Irving Medical Center. This study is part of a larger study called. universe This includes a total of two independent randomized clinical trials (Cosmos-Web, current and Cosmos-Mind published in 2022).

“It is noteworthy that two separate studies from the Cosmos randomized trial found that a daily multivitamin improved memory and slowed cognitive decline. It shows promise as a safe, accessible, and affordable approach to protect the health of the elderly.”, summarized by Professor Joan Manson in a note from Brigham.

Cosmos Web explains that more than 3,500 adults over the age of 60 were randomly assigned to take a daily multivitamin supplement or a placebo for three years. release From Irving Medical Center.

At the end of each year, the volunteers underwent a series of online cognitive tests (memorizing words) at home designed to test memory function in the hippocampus (the region of the brain affected by normal aging).

By the end of the first year, people taking a daily multivitamin improved their memory compared to those taking a placebo.

This improvement persisted throughout the 3-year study, and the researchers calculated that the multivitamin intervention improved memory by 3.1 years compared with the placebo group.

Both the current study and the previous study showed that the participants who benefited the most may be those with a history of cardiovascular disease.

Adam Brickman of Columbia University said: “There is evidence that people with cardiovascular disease may have lower levels of micronutrients that can be corrected with multivitamins, but at this time, it is unclear why this group is more effective. I don’t know how big it is,” he said.

According to the researcher, “these results are encouraging and will undoubtedly pave the way for important follow-up studies of the effects of multivitamin supplements on cognition.”

But Brickman cautions that no supplement of any kind should replace other, more holistic ways of getting the same micronutrients. “Multivitamins are generally safe, but you should always consult your doctor before taking them.”

Cosmos-Web provides evidence that multivitamin supplementation has cognitive benefits, but further research is needed to identify the specific nutrients that contribute most to this benefit and the underlying mechanisms associated with it. The authors summarize that it is necessary.

Additional studies are also needed to determine whether the results are generalizable to more diverse populations (the current study participants were predominantly non-Hispanic white).
