Doctors at Michigan State University have found that vitamin D can help cancer patients live longer if taken for at least three years.
The findings, presented at the annual meeting of the American Society of Clinical Oncology on June 3, 2019, suggest that vitamins have significant benefits in addition to their promoting effect on bone health.
According to 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 prevents cancer." Tarek Haykal, an attending physician in internal medicine at Michigan State University and the study's author.
The researchers looked at disease prevention data from more than 79,000 patients in studies that randomly compared data from patients taking vitamin D or a placebo up to three years. Haykal and his team focused their attention on any information related to cancer incidence and mortality.
"The difference in mortality between the vitamin D and placebo groups was statistically significant enough to indicate its importance in the cancer population," Haykal said.
While these findings show promise, Haykal cautions that the exact vitamin intake and levels needed in the blood are still unknown. He also said it's not clear how much longer vitamin D might extend life, or why.
"There are still a lot of questions that need more research," Haykal said. All we can say is that it takes at least three years to see results with supplements."However, the results show enough promise that Haykal would like to see more doctors, especially oncologists, prescribe vitamin D to patients.
"We know the benefit of it is the least side effects," he said. So it has a lot of potential."
