A new study suggests that vitamin D may protect against prostate cancer. Men around age 65 who had a positive biopsy for prostate cancer who took 4000 IU/day of Vitamin D for a full year had a 55% decrease in the number of follow up positive prostate biopsies. Men who did not take vitamin D, 2\3 had progression compared to only 1\3 who took vitamin D.
Bottom Line; This is a report of a small study and certainly the results are encouraging but preliminary and more testing needs to be done. But as my wise Jewish mother would say, “It may not help, but it voidn’t hoit!”
