A small new study suggests that vitamin D may reverse progression of low-grade prostate tumors.
For the study, 37 men were divided into two groups. One group received 4,000 international units of vitamin D per day while the placebo group didn´t receive vitamin D, and then after a period of 60 days their prostate glands were removed and examined.
"Vitamin D decreases inflammation in tissues, and inflammation is a driver of cancer. In greater than 60 percent of those taking it, vitamin D actually made the cancer better," study leader Bruce Hollis explained.
