Vitamin D May Slow the Progression of Low Grade Prostate Cancer - Preliminary results of a small randomized trial
Researchers from the Medical University of South Carolina recently presented the early results of a small randomized trial investigating the effect of Vitamin D on patients with low grade prostate cancer undergoing radical prostatectomy. In this trial, 37 men who were waiting to undergo surgery for their prostate cancer were randomly assigned to receive either 4,000 IU (international units) of Vitamin D per day or placebo. All patients then underwent radical prostatectomy and their prostates were examined.
Results: Lead researcher, Bruce Hollis, PhD, reported that "In greater than 60% of those taking it, Vitamin D actually made the cancer better." He reported that in some cases the tumors shrank and in others the cancer went away. However, the study was small, and results from a larger trial aren't expected for several years, he added.
The Bottom Line: It is intriguing to think that Vitamin D, a vitamin that many physicians recommend for a variety of ailments, is also helpful in fighting prostate cancer. But results are preliminary and further study remains to be done to reach any definite conclusions about Vitamin D and its effect on prostate cancer.
