Vitamin D Supplements Help Preserve Telomere Length in Aging Adults
- Researchers conducted the VITAL trial, a randomized, double-blind study from 2011 to 2017 in the U.S., to evaluate vitamin D3 and omega-3 effects on telomere length in adults aged 50 and older.
- The study focused on telomere shortening because it naturally occurs with aging and increases the risk of age-related diseases, motivating investigation of supplementation benefits.
- A sub-study within the VITAL trial assessed telomere length in over a thousand participants and found that daily supplementation with 2,000 IU of vitamin D3 effectively reduced telomere shortening over a four-year period compared to placebo, whereas daily intake of 1 gram of omega-3 fatty acids did not influence telomere length.
- Vitamin D3 supplementation was shown to prevent telomere shortening equivalent to nearly three years of aging, leading Haidong Zhu, the study’s first author, to describe it as a potentially effective approach to slow certain aspects of aging, while noting that additional studies are needed.
- These findings suggest vitamin D supplements may slow cellular aging and partly explain reduced risks of some chronic diseases, but experts urge more research to clarify broader health outcomes and optimal use.

Vitamin D Supplements May Slow Process Linked to Aging, New Study Says
A study published on Thursday found that people with higher vitamin D intake may be slowing a process linked to aging. In a paper released by the American Journal of Clinical Nutrition on May 22, Mass General Brigham and the Medical College of Georgia researchers looked at results from a randomized controlled trial known as VITAL showing that taking vitamin D3 supplements can help support telomeres, which are protective ends on chromosomes. “VIT…
