A new study has found that people who take vitamin D supplements are significantly less likely to develop cancer, stroke or diabetes, and that their risk of death from any cause is reduced by at least 25 percent.
The findings, reported in the journal The Lancet Oncology, provide a rare glimpse into how the human body reacts to a variety of nutrients, which could shed light on the benefits of taking them in particular.
“The fact that vitamin D protects against cancer, cardiovascular disease, and diabetes, even in people who are predisposed to them, is pretty extraordinary,” said Dr. Andrew Weinstock, the study’s senior author and an assistant professor at Boston University School of Medicine.
“We really don’t know the whole story, but it’s pretty clear that vitamin d is a key player in preventing these types of diseases.
And the fact that it has such a protective effect even in predispositive people is quite remarkable.”
Vitamin D is the vitamin that protects the human immune system from harmful viruses, bacteria and parasites.
It’s also the primary source of vitamin K, which is crucial for bone health and helps maintain a healthy blood supply.
Vitamin K plays a critical role in the production of collagen, a key component of skin and nails, and helps to repair damaged tissue.
The researchers studied 1,976 adults with diabetes who had either high blood pressure or diabetes and a history of other chronic diseases.
Those with high blood or diabetes were also more likely to be taking supplemental vitamin D.
After analyzing their data for four decades, the researchers found that participants who were taking vitamin D regularly had a reduced risk of heart disease, cancer, diabetes and strokes.
They also had lower rates of diabetes and cancer, and a reduction in risk of all causes of death.
They were also less likely than participants who did not take vitamin, for example, to develop type 2 diabetes.
In fact, those who were vitamin D-deprived had a 50 percent reduced risk for all of those conditions, compared to those who had low blood pressure.
“That means that the effect of vitamin D is significant,” Weinstocks said.
“It’s a really remarkable result.
People who are in good health should be taking it.”
He said he hopes the findings will also lead to new research on how vitamin D affects the immune system.
Vitamin D is known to protect the body from some of the most common types of cancer, including melanoma, breast cancer, colon cancer and lung cancer.
The study was funded by the National Institutes of Health and the Office of Dietary Supplements, which includes the Centers for Disease Control and Prevention, National Institutes for Health, and the U.S. Department of Health.
