Three Studies Link 24-Month Multivitamins and 4-Week Diet Shifts to Slower Biological Aging

Summary
Three new studies tied everyday habits to slower biological aging, including a 24-month trial in which daily Centrum Silver users showed slightly slower epigenetic aging than a placebo group.
A separate diet study found older adults improved the gap between biological and chronological age after just 4 weeks, with the biggest gains in plant-forward, complex-carbohydrate diets; a high-fat omnivorous diet showed no meaningful change.
A 2026 fitness study of 24,576 adults 65 or younger linked higher midlife cardiorespiratory fitness to longer health span and life span; men showed 2% longer health span, 9% fewer diseases and 3% longer life span, with similar results in women.
Researchers and outside clinicians said the findings are encouraging but preliminary, stressing that biomarker shifts do not yet prove fewer heart attacks, cancers or longer survival.
Taken together, the reports add to evidence that exercise, diet and possibly multivitamins may help delay age-related decline, though long-term benefits still need confirmation.

Biological Age vs. Chronological Age: What Multivitamins, Diet, and Lifestyle Can—and Can’t—Do for Healthy Aging
Overview
Recent results from the large NIH-funded COSMOS trial show that daily multivitamin supplementation can modestly slow biological aging in older adults, especially for those who are biologically older than their actual age. The trial also found that taking a daily multivitamin improved memory and overall cognitive function over two years. These benefits suggest that multivitamins are having a real effect inside the cells of older individuals, particularly those over 60. The findings highlight that while multivitamins are not a cure-all, they may offer meaningful support for healthy aging when combined with a balanced lifestyle.
