Manuel Viso, MD: "Taking vitamin D3 can slow biological aging by three years."

Vitamin D, telomeres, and longevity are at the center of a scientific breakthrough that has sparked interest in the medical community. Among them, Dr. Manuel Viso highlights the potential of this micronutrient to slow cellular deterioration , calling it " super amazing, " adding: "I loved it."

The research, published in The American Journal of Medicine , is part of the VITAL trial and analyzed more than 25,000 adults over four years. Those who took 2,000 IU of vitamin D3 daily , known as active vitamin D, showed less telomere length loss , which is associated with a reduction in the rate of biological aging. “Taking this vitamin can slow biological aging by three years ,” Viso summarizes.

The doctor and science communicator shared his enthusiasm for the discovery on social media: "I wanted to tell you about a super surprising study that I loved, and it's a study from Harvard National School together with Augusta University, and what they saw is that daily vitamin D supplementation could reduce aging ."

Telomeres and shoelaces

To explain the process, Viso uses a very clear image: "And how did he do it? Well, by protecting the telomeres. And what are telomeres? Well, the end caps of chromosomes. In other words, telomeres are like those little plastic caps on shoelaces that prevent them from fraying. "

Viso states that " every time a cell divides, the telomeres shorten. When telomeres are too short, cells stop functioning or die. And that's when cellular, organic, and physical aging begins." In this regard, the doctor assures that "the researchers hypothesized that by taking vitamin D in this study, they saw that telomeres lasted much longer or that at least their shortening slowed down, which would mean at least three fewer years of biological aging."

The 25,000 people who took part in the study took 2,000 IU of vitamin D3 daily and showed less telomere length loss.

Although the results are promising, the specialist insists on caution: "Obviously, these are studies that need to be taken with caution because they require further research." Still, he emphasizes that maintaining adequate vitamin D levels through sunlight , diet, or supplementation can be key to cellular health over time.
