A new study suggests that Vitamin D supplements may support telomere health, the protective ends of chromosomes crucial for healthy aging. This indicates Vitamin D may help slow aging, fueling optimism that it could enhance longevity and health.
Telomeres are at the ends of our 46 chromosomes and shorten with each cell division. Once they become critically short, cells lose their ability to divide and ultimately perish. Shortened telomeres are associated with age-related chronic conditions such as heart disease, cancer, and osteoarthritis.
The research included a randomized trial of about 1,000 individuals, all over 50 years old that were split into two groups. One group received 2,000 IU of vitamin D supplements daily, while the other group took placebo pills.
Vitamin D showed a beneficial effect on telomere length. Participants taking vitamin D experienced minimal telomere shortening at the two- and four-year marks, while the placebo group saw significant telomere shortening at both intervals. After four years, the vitamin D group exhibited less than half the telomere shortening compared to the placebo group.
By preserving telomere length and safeguarding DNA, vitamin D supports cellular integrity and may prolong the functional lifespan of immune cells. It can also help regulate inflammation, which is linked to cellular aging and age-related diseases. Vitamin D stabilizes chromosomes, which enables cells to operate more efficiently and lowers the risk of premature cell death.
Future studies can investigate the reasons behind vitamin D’s effects on telomere length, such as its potential influence on telomerase, an enzyme that extends telomeres, or its role in protecting against DNA damage.

While melanoma and squamous cell carcinoma are generally slow-growing and rare, a new study finds that people with tattoos face a greater risk of developing melanoma. While tattoos raised melanoma risk, they did not increase the odds of squamous cell carcinoma, another sun-driven skin cancer that, unlike the much more lethal melanoma, arises from different skin cells.
A groundbreaking new study reveals that soybean oil, the most consumed edible oil in the U.S., may directly drive obesity, independent of calorie intake. Scientists now have compelling evidence that the problem isn’t the oil itself. Instead, the real culprit appears to be the harmful metabolites soybean oil produces once inside the body.
New research shows that keeping your heart healthy might depend on what’s happening in your gut. Inside your digestive system live trillions of bacteria, viruses, and fungi, known as the gut microbiome, that influence far more than just digestion. These microscopic inhabitants play a surprisingly powerful role in protecting your heart and reducing the risk of cardiovascular disease.
