In case you need another reason to take vitamin D, a new study has suggested a role for low levels of vitamin D as a contributing factor to erectile dysfunction. Vitamin D has previously been shown to help prevent breast, colon and prostate cancer, MS, colds and flus, and low levels are associated with greater risk for heart attack.
The study found that those with severe erectile dysfunction (ED) had significantly lower vitamin D levels than those with mild ED, and that deficiency was worse in those with arteriogenic ED than in non-arteriogenic ED. The authors speculate that low vitamin D may be part of the mechanism that promotes dysfunction of the vascular endothelium, contributing to ED.
