How does multivitamins help in improving the overall health?

Hello,Welcome to iclinq.com,I can understand your concern.

Complementary medicine use is becoming increasingly popular with multivitamins being the most commonly used vitamin supplement. Although adequate vitamin and nutrient concentrations are necessary for optimal health and cognitive functioning, there is no scientific consensus as to whether multivitamin use prevents cognitive decline or improves mental functioning. The aim of the was to determine if multivitamins can be used efficaciously to improve cognitive abilities Our current options for improving brain health are limited. For example, regular exercise, optimal weight, and a heart-healthy diet can improve cardiovascular health and lower the chances of certain types of dementia, such as dementia due to strokes. Beyond such common-sense measures, no available medicines, supplements, or treatments reliably improve brain function over the long term, despite advertisements claiming otherwise. That's why researchers continue to explore whether certain foods or supplements could prove effective. In a recent study published in Alzheimer's and Dementia, more than 2,200 volunteers ages 65 and older were randomly assigned to receive cocoa or a placebo, a multivitamin or a placebo, or both cocoa and a multivitamin for three years. The multivitamin chosen for this study was Centrum Silver, which contains 27 vitamins, minerals, and other nutrients in various amounts. When tests of cognition were analyzed at the end of the trial, those receiving cocoa did not demonstrate any improvement. But those assigned to take a multivitamin had improved scores on tests of overall brain function (especially in people with cardiovascular disease) memory executive function (tasks such as planning ahead or remembering instructions). Based on these findings, the researchers estimated that three years of multivitamin use could slow age-related decline in brain function by as much as 60%.
