This Popular Supplement May Actually Slow Biological Aging, Scientists Reveal
Brigham and Women’s Hospital & Harvard Medical School, March 30, 2026 (SciTech Daily)
A daily multivitamin–multimineral supplement may do more than fill nutritional gaps. In a study of 958 older adults, researchers found that two years of daily supplementation modestly slowed changes in certain DNA-based markers linked to biological aging.
The findings, published in Nature Medicine, suggest that nutrition may subtly influence some of the molecular patterns scientists use to track how the body ages over time.
Howard Sesso and colleagues measured five DNA-based markers of biological aging in blood samples from 958 participants with an average age of about 70 years.
In a pre-specified analysis of a randomized clinical trial, participants were assigned to take either a daily multivitamin–multimineral tablet, a cocoa extract supplement, or a placebo. The trial followed participants for two years.
The researchers found that people taking the multivitamin–multimineral supplement showed a slower yearly increase in two epigenetic clocks associated with mortality risk: PCPhenoAge and PCGrimAge. The rate of increase was reduced by about 2.6 months for PCPhenoAge and 1.4 months for PCGrimAge.
Among participants who showed faster-than-average biological aging at the start of the study, the slowing effect was greater. In this group, the PCGrimAge clock slowed by about 2.8 months.
