Erectile Dysfunction (ED), Vitamin D, Sunlight and Nitric Oxide

Erectile Dysfunction (ED), Vitamin D, Sunlight and Nitric Oxide

By Marc Sorenson, EdD

A new article on November 30, 2015, from the Daily Mail, discusses breaking research on the association between ED and vitamin D.[1] The research from Johns Hopkins University, by Dr. Erin Michos and her colleagues, was conducted on 3,400 men over age 20, 30% of whom were vitamin D deficient, and 16% of whom reported symptoms of ED. Men with Vitamin D deficiency were 32% more likely to suffer ED than those whose levels were sufficient.

Although I, along with Dr. Grant, were the first to hypothesize that vitamin D deficiency could lead to ED,[2] I have moderated my opinion somewhat. It is entirely possible that higher vitamin D levels are really a surrogate measurement for sunlight exposure. Although vitamin D probably has a positive affect on ED, the UVA portion of sunlight has a nearly immediate effect in dilating the blood vessels[3] through the production of nitric oxide (NO), which is absolutely necessary for producing an erection.[4] Viagra and other ED drugs work by inhibiting the breakdown of NO, which keeps NO in circulation for a longer period.[5] But, they don’t always work and can have many deleterious side effects.[6]

My hope is that research will be done to determine the effectiveness of sunlight exposure in alleviating the condition. Of course, the underlying cause of ED is consuming foods that occlude the arteries. Sunlight and/or vitamin D serve as palliatives to that occlusion, as do the ED drugs. A nutrition program filled with colorful fruits and vegetables,[i] along with ample sunlight exposure, would, in my opinion, produce the very best results in mitigating or perhaps reversing the disease.
