Daily Multivitamins May Slow Biological Aging in Older Adults, New Study Finds

A new study published in Nature Medicine suggests that taking a daily multivitamin may help slow biological aging in older adults. Researchers analyzed data from nearly 1,000 participants aged 60 and older and found that those who took a multivitamin experienced slower changes in two key “epigenetic clocks,” which measure biological aging through DNA methylation. 

The study drew from the large COcoa Supplement and Multivitamin Outcomes Study (COSMOS), a randomized, double‑blind, placebo‑controlled trial conducted between 2016 and 2020. Participants who took multivitamins showed measurable reductions in the pace of aging compared with those who received a placebo. The effect was especially strong among individuals whose biological age was already higher than their chronological age. 

Researchers emphasized that while many older adults take multivitamins without knowing whether they help, these findings offer promising evidence that supplementation may support healthier aging. However, they also noted that cocoa extract — another supplement tested in the study — showed no measurable impact on aging.

New Study Shows Simple Lifestyle Changes Could Reduce Dementia Risk by 25%

A growing body of research suggests that older adults may significantly reduce their risk of dementia through small but consistent lifestyle adjustments. According to recent reporting, experts say that incorporating regular brain‑stimulating activities—such as puzzles, reading, or structured memory exercises—can help counteract the cognitive decline associated with aging. 

Researchers also emphasize the importance of staying physically active. Even light daily movement, such as walking or stretching, may help maintain healthy blood flow to the brain and reduce sedentary habits that have been linked to increased dementia risk. 

Health professionals note that these findings offer hope for seniors seeking proactive ways to preserve cognitive health without relying solely on medical interventions. As dementia rates continue to rise globally, the study’s insights provide actionable steps that older adults and caregivers can begin implementing immediately.
