A novel study suggests that daily vitamin D3 supplementation could significantly impact aging. Over four years, participants taking the supplement showed less DNA damage, corresponding to slower aging—essentially reversing nearly three years of aging compared to a placebo group. The research indicates the potential benefits of vitamin D for telomere preservation, inflammation reduction, and chronic disease risk lowering, urging further long-term studies despite the participants exceeding standard dosage recommendations. Experts caution about vitamin D overconsumption due to possible health risks.
Given the study was relatively short, the team said the results were 'promising' and they've called for longer research to be conducted.
VITAL is the first large-scale and long-term randomized trial to show that vitamin D supplements protect telomeres and preserve telomere length.
