Harvard study reveals multivitamin supplementation may reduce cognitive aging in older adults by up to two years.
In a recent study, scientists at Harvard Medical School have discovered a potential new method to thwart cognitive decline in older adults using multivitamin-mineral (MVM) supplementation. The study, recently published in The American Journal of Clinical Nutrition, provides promising evidence that daily MVM supplementation could play a crucial role in enhancing cognitive function, particularly in episodic memory, among older individuals.
As the global population ages, cognitive decline becomes a growing concern. Age-related cognitive deterioration can significantly impact one’s quality of life, leading to challenges in memory, problem-solving, and attention. Notably, previous research has highlighted various factors contributing to cognitive decline, including a poor diet, increased oxidative stress, and the buildup of toxic proteins called amyloid beta which are believed to be a primary driver of Alzheimer’s disease. However, the role of nutrition supplements, specifically MVM, in mitigating these effects has remained unclear until now.
The COSMOS (COcoa Supplement and Multivitamin Outcomes Study) trial, led by Chirag Vyas and colleagues, involved 21,442 participants, offering a unique insight into the long-term effects of MVM on cognitive health in elderly subjects. The study’s innovative approach included detailed, in-person neuropsychological assessments to evaluate the effectiveness of MVM supplementation over a two-year period.
The results from the COSMOS-Clinic sub-study, involving 573 participants, indicated a modest but significant improvement in global cognition and a more pronounced effect on episodic memory due to MVM supplementation. These findings were further supported by a comprehensive meta-analysis across three COSMOS cognitive substudies. What’s more, the degree of MVM’s positive impact on global cognition was likened to a reduction in cognitive aging by approximately two years, further demonstrating MVM’s potential as a cognitive intervention for older adults.
This research marks a significant step in understanding and potentially improving cognitive health in older adults through nutritional interventions. The study’s implications extend beyond the academic sphere, offering actionable insights for healthcare providers and individuals seeking to preserve cognitive function with age. It suggests that MVM supplementation could be an effective, non-invasive strategy to counteract the effects of aging on the brain.
The study’s findings open the door for further research to confirm and expand upon these results. The broader impact on public health could be substantial, potentially offering a simple yet effective means to enhance cognitive longevity and quality of life for the aging population. However, it is crucial to note that while MVM supplements show promise, they are not a panacea for aging and age-related diseases and should be considered as part of a holistic approach to healthy aging that includes diet, exercise, and regular mental stimulation.
