Vitamin D levels improve cancer survival rates, according to new research

VitaminDImprovesCancerSurviAccording to a new study reported in Endocrine Society’s Journal of Clinical Endocrinology & Metabolism, cancer patients who have higher levels of vitamin D at the time they are first diagnosed tend to have better survival rates than patients who are vitamin D-deficient. The patients with higher vitamin D levels also remain in remission longer, according to the study.

Perhaps the most important conclusion to take from the results of this study is that, though vitamin D likely offers immune help at any time, it is best to be fortifying yourself before the emergency arises.

This particular meta-analysis study looked at the results of 25 separate studies that measured vitamin D levels in cancer patients at the time of diagnosis and tracked survival rates. In most of the research, patients had their vitamin D levels tested before they underwent any treatment for cancer. The study found a 10 nmol/L increase in vitamin D levels was tied to a 4 percent increase in survival among people with cancer.

“By reviewing studies that collectively examined vitamin D levels in 17,332 cancer patients, our analysis demonstrated that vitamin D levels are linked to better outcomes in several types of cancer,” said one of the study’s authors, Hui Wang, MD, PhD, Professor of the Institute for Nutritional Sciences at the Shanghai Institutes for Biological Sciences at the Chinese Academy of Sciences in Shanghai, China. “The results suggest vitamin D may influence the prognosis for people with breast cancer, colorectal cancer and lymphoma, in particular.”
