Vitamin D is linked to erectile dysfunction
A new study shows a connection to Low D and ED.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5503426/ – The role of Vitamin D supplementation on erectile dysfunction
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5817208/ – In the whole sample, after performing logistic regression models, higher levels of 25(OH) vitamin D were significantly associated with high values of total testosterone and of all the International Index of Erectile Function (IIEF) questionnaire parameters. On the other hand, higher levels of total testosterone were positively and significantly associated with high levels of erectile function and IIEF total score. After vitamin D replacement therapy, total and free testosterone increased and erectile function improved
I supplement with vitamin D in the winter (as per UK government recommendations given the lack of sunlight in Scotland), and I can’t say I’ve noticed much difference.
In the UK it’s estimated that about half the population has vitamin D insufficiency, so seasonal supplementation makes sense. although the effect on bone health is probably more of a concern.
