Can vitamin D help slow biological aging? A new study suggests it can.
According to research published in The American Journal of Clinical Nutrition (May 2025), taking 2,000 international units (IU) of vitamin D3 daily may help slow the shortening of telomeres , DNA structures that are closely linked to aging and chronic diseases.
And why is this important for our health?
Because telomeres act like a “biological clock” in our cells . As we age, they shorten, and when this happens too quickly, it can lead to increased inflammation, increased oxidative stress, and a weakened immune system.
In this study, the group receiving vitamin D for four years lost less telomere length compared to the group taking a placebo.
Although the results should be viewed with caution due to some study limitations, these data raise new questions about how certain micronutrients, such as vitamin D, might influence the aging process from within.
Even so, it’s important to remember that moderate, safe sun exposure remains the most natural and effective way to obtain vitamin D. However, in these times—due to lifestyle choices, indoor work, or lack of sunlight in some places—supplementation can be a great help.
