Vitamin D supplements may slow aging: Study
- The VITAL randomized, double-blind, placebo-controlled trial studied vitamin D3 supplementation effects on telomere length over four years in U.S. adults aged 50 and older.
- This trial arose from telomere shortening as a natural aging process linked to age-related diseases and sought to test if vitamin D3 could slow this shortening.
- The sub-study involved 1,054 participants whose white blood cell telomere length was measured at baseline, Year 2, and Year 4 to assess supplementation impact.
- Results showed vitamin D3 supplements significantly reduced telomere shortening by about 140 base pairs, equivalent to nearly three years of aging, while omega-3 had no effect.
- The findings suggest vitamin D3 may slow cellular aging by preserving telomere length, though researchers emphasize further study is needed to confirm broader implications.

Common daily vitamin could slow biological aging, major study suggests
Vitamin D might be doing more than just supporting bone health — it could also help the body age slower, according to a new study led by researchers at Mass General Brigham (MGB) and the Medical College of Georgia. The study, published this month in The American Journal of Clinical Nutrition, reveals that taking vitamin D supplements may protect against biological aging by slowing the shortening of telomeres, the tiny caps on DNA that naturally …
Experts reveal hidden ways sugar accelerates aging beyond just weight gain
Sugar is not so sweet when it comes to aging, especially when it's about your skin, brain health and the inflammation in your body, experts told Fox News Digital. "In essence, sugar acts like a slow poison when consumed in excess. It silently damages the structures that keep us young, our collagen, our vasculature, our metabolic systems and even our brain," Daniel Tawfik, a molecular biologist and co-founder of Healthspan, a digital medical clin…
