A new study suggests that getting enough vitamin D may be key to living longer and aging healthfully. Researchers followed over 1,000 healthy adults for four years and found that taking 2,000 international units (IU) of vitamin D3 daily slowed down telomere shortening, a measure of biological age.
Telomeres are the protective caps on chromosomes that wear down with age. Dr. Joseph Mercola, board-certified family physician, explains that when telomeres get too short, cells can’t divide properly and start to malfunction or die. Vitamin D3 helped slow down this process, reducing the risk of heart disease, cancer, and premature aging symptoms.
The study’s findings suggest vitamin D3 has anti-inflammatory effects, immunity protection, and a role in cell function, particularly within the mitochondria. This may help preserve metabolic power, resilience, and brain function.
While the study is promising, its limitations include a lack of broad demographic diversity. Experts agree that more research is needed to fully understand the effects of vitamin D on aging. However, this study adds credibility to the role of vitamin D3 in slowing age-related decline.
To maintain good health, experts recommend practicing other healthy habits, such as eating a Mediterranean-style diet, exercising regularly, getting good sleep, and maintaining an active social life. Vitamin D can be obtained through sun exposure, but supplements may be necessary for those with deficiencies. It’s essential to talk to a doctor before starting any supplementation regimen.
