Research finds that vitamin D extends the survival time of cancer patients
2020-10-15
Doctors at Michigan State University found that taking vitamin D for at least three years can help cancer patients live longer.
The study results indicate that vitamins not only promote bone health but also have significant benefits. The findings were presented at the American Society of Clinical Oncology annual meeting on June 3, 2019.
According to data from the Centers for Disease Control and Prevention, cancer is the second leading cause of death in the United States.
"Vitamin D can significantly reduce the risk of death in cancer patients, but unfortunately, there is no evidence that it can prevent cancer," said Tarek Haykal, an internist at Michigan State University and the study's author.
Researchers observed disease prevention-related data from more than 79,000 patients across multiple studies, which randomly compared data of patients using vitamin D or placebo for up to three years. Haykal and his team focused on any information related to cancer incidence and mortality.
Haykal said, "The difference in mortality between the vitamin D group and the placebo group is statistically very significant, which is enough to demonstrate its importance for the cancer population."
Although these findings show promise, Haykal warned that the exact vitamin intake and the required blood levels are still unknown. He also said it is unclear how much vitamin D can extend life and why such results occur.
Haykal said, "There are still many questions that require more research. We can only say that taking supplements for at least three years is needed to see effects."
However, the results show enough hope that Haykal hopes to see more doctors, especially oncologists, prescribe vitamin D to patients.
He said, "We know its benefits come with minimal side effects. Therefore, it has great potential."
