The aging population is of course a cause for concern and brings with it new challenges for the medical industry. As cognitive decline and memory loss become more significant concerns there are more and more studies into their prevention.
And we will be reviewing one particularly interesting study that has been recently published. The study monitored 5000 adults and lasted over two years and it seems that incorporating a daily multivitamin could do a lot to preserve memory and slow cognitive aging.
Now, anyone who knows about vitamin deficiency rates within the US is unlikely to be too surprised as many vitamins required for brain health, such as vitamin D are deficient in up to 70% of people depending on the region, with some vitamins like magnesium not being much better, at least in terms of sub clinical deficiencies.
Understanding the Study: Cocoa Supplement and Multivitamin Outcomes Study (COSMOS)
The Cocoa Supplement and Multivitamin Outcomes Study (COSMOS) represents a groundbreaking clinical trial conducted by researchers at Mass General Brigham.
The large scale study aimed to assess the effects of cocoa extract and multivitamin supplements on various health outcomes including cognitive function.
The trial consisted of three separate studies and involved over 5,000 participants.
The final study, published in The American Journal of Clinical Nutrition, focused specifically on the impact of a daily multivitamin on memory and cognitive aging.
Positive Results: Multivitamin Benefits Memory and Global Cognition
The lead author Dr. Chirag Vyas, an instructor in investigation at Massachusetts General Hospital, emphasizes that taking a daily multivitamin can slow cognitive aging and prevent memory loss.
The meta-analysis of the three studies conducted as part of the trial consistently demonstrated the positive impact of multivitamins on global cognition, including reasoning, attention, planning, and episodic memory.
The Specifics of the Study: Cognitive Assessments and Multivitamin Intervention
In the third and final study of the COSMOS trial, 573 adults aged 60 and above were selected to participate.
These individuals were divided into two groups: one group received a daily multivitamin, while the other received a placebo.
Over a period of two years, the researchers evaluated their cognitive function through in-person assessments and a series of cognitive tests.
The results indicated a modest improvement in global cognition and a significantly positive change in episodic memory among those taking the multivitamin.
So What Does The COSMOS Multivitamin Study Show?
The findings of the COSMOS trial and meta analysis make a pretty good case for the benefits of incorporating a daily multivitamin into the routine of older adults. While the specific micronutrients responsible for these advantages require further investigation, the evidence suggests that multivitamins can slow cognitive aging and preserve memory.
