Taking a multivitamin every day can ‘significantly’ improve memory and slow cognitive ageing—and it should be taken by older people who are worried about dementia and Alzheimer’s disease.
The supplement can make your brain two years younger, say researchers in the Cosmos (Cocoa Supplement and Multivitamin Outcomes Study) trial.
A multivitamin, containing around 20 essential micronutrients, has been tested against a dummy pill. The researchers assessed the mental capabilities of a group of 573 participants who were given the multivitamin or a placebo for two years.
The study is the third in a series of Cosmos trials that have consistently shown the benefits of vitamins on mental ageing. “The finding that a daily multivitamin improved memory and slowed cognitive ageing in three separate placebo-controlled studies in Cosmos is exciting and further supports the promise of multivitamins as a safe, accessible and affordable approach to protecting cognitive health in older adults,” said JoAnn Manson of Mass General Brigham, where the Cosmos study is based.
With an ageing population that is worried about dementia and Alzheimer’s, taking a multivitamin every day is, well, a no-brainer.
